Precautions during usage
Acquisition of CE marking
1. Avoid locations subject to
flammable or corrosive gases,
excessive dust, oil, vibrations, or
excessive shocks.
2. Since the main-unit is made of
polycarbonate resin, avoid contact
with or use in environments
containing methyl alcohol, benzene,
thinners, and other organic solvents;
and ammonia, caustic sodas, and
other alkaline substances.
3. Power supply superimposed surge
protector
Although a surge protector will withstand
standard-waveform voltage with the
values in the next table, anything above
this will destroy the internal circuit. You
should therefore use a surge absorber.
• Surge waveform
[±(1.2×50) µs uni-polar full wave voltage]
4. In order to maintain the
characteristics, do not remove the
timer case.
5. When installing the panel, use the
ATA4811 mounting frame (Sold
separately).
6. If you change the operating voltage,
be sure not to allow leak current into
the timer.
7. Avoid leaving the unit powered
continuously. Leaving the unit
powered up with output set to ON
continuously for a long period of time
(about 1 month or more) will wear out
the electronic components. If you will
be keeping it powered continuously,
combine with a relay to create the
circuit shown below:
8. The timer setting dial should only be
turned within the range indicated on
the dial face. Turning it too far may
break the stopper and cause damage
to internal components.

Please abide by the conditions below
when using in applications that
comply with EN61812-1.
1. Overvoltage category III,
pollution level 2
2. The load connected to the output
contact should have basic insulation.
This timer is protected with basic
insulation and can be double-
insulated to meet EN/IEC
requirements by using basic
insulation on the load.
3. Please use a power supply that is
protected by an overcurrent protection
device which complies with the EN/
IEC standard (example: 250 V 1 A fuse,
etc.).
4. You must use a terminal socket or
socket for the installation. Do not
touch the terminals or other parts of
the timer when it is powered. When
installing or un-installing, make sure
that no voltage is being applied to any
of the terminals.
5. Do not use this timer as a safety
circuit. For example when using a
timer in a heater circuit, etc., provide a
protection circuit on the machine side.

the set time has elapsed, it goes off.
Also, when pins 2to 6are released (the start input goes off), the output
goes on, and after the set time has elapsed, it goes off.
If the status of pins 2to 6(screw-tightening pins xand c) changes dur-
ing the time-limit interval (the start input goes from on to off, or from off to
on), the time-limit interval is restarted from the point at which the change
took place.
If the power supply is turned off, or pins 2to 7(screw-tightening pins xto

Note) During time-limited operation, the time-limited operation is stopped while
the pins 2to 5(screw-tightening pins xto b) are being shorted (the stop
input is on). When the pins are released, time-limited operation resumes.
• If using a time-limit start when the power is turned on, and a reset when
the power is turned off, pins 2to 6(screw-tightening pins xand c)

• Turn the operation mode selector switch to the position.
When pins 2to 6(screw-tightening pins xand c) are shorted (the start
input is turned on) with the power supply on, the limited time interval begins,
and the output goes on after the set time has elapsed. After the output has
gone on, it goes off when the set time has elapsed, and this process is sub-
sequently repeated.

1. Input connections (PM4H-A type)
1) Be sure not to use terminal as the
common terminal of the input signal as
shown in Fig. A. Otherwise, the internal
circuit of the timer may be damaged.
Use terminal as the common terminal
as shown in Fig. B.
If the circuits is connected as in Fig. C,
the internal circuits must be broken. Be
sure to connect the circuit as in Fig. D.
2) When one input signal is simultane-
ously applied to more than one timer, be
sure to avoid the wiring shown in Fig. E.
Otherwise, the short-circuit current will
flow and cause damage. Be sure to align
the polarity of the power supply as
shown in Fig. F.
3) Terminal -(screw terminal x-c)
should be connected as the start input.
Connect terminals -(screw terminal
x-v) for reset signal input. Connect ter-
minals -(screw terminal x-b) for
stop signal input. Be sure not to connect
with other terminals and apply excessive
voltage. The internal circuit will be dam-
aged.
4) The input wiring other than the power
supply circuit should avoid these condi-
tions, high-voltage wiring and parallel
wiring with power wire. Wire in short with
using the shielding wire or metal wiring
tube.
5) For start, reset and stop input, use
gold-plated contact with high reliability.
Since contact bouncing causes errors in
the start, use an input contact less
bounce time.
6) Keep the minimum signal input time
over 0.05 s.
2. Input signal conditions
(PM4H-A type)
1) Connection of contact input (Pin type
example
Use gold-plated contacts with high-relia-
bility. The bounce time at the contacts
causes errors in the timer operation time.
Accordingly, use start input contact
whose bounce time is short. The resis-
tance when shorted should be less than
1kΩ, and when open resistance should
be more than 100kΩ.
For the screw terminal type, connect the
terminal xto the each input signal.
2) Connection of non-contact input (Pin
type example)
(open-collector)
Apply the open-collector connection. The
characteristics of the transistor used
must be VCEO=10V or more, IC=10mA or
more, and ICBO=6µA or less. Additionally,
the input impedance must be 1kΩor
less, and the residual voltage must be
0.6V or less.
For the screw terminal type, connect the
terminal xto the each input signal.
3) Connection of non-contact input (Pin
type example)
(voltage input)
Even if the open collector is not used,
input is also possible from the non-con-
tact circuit of 6 to 30V DC. In this case,
the start input is turned on when the sig-
nal is turned from H to L.
The residual voltage must be 0.6V or
less when Q is on. On the AC type, an
insulated transformer is required as the
power supply for the photoelectric sen-
sor, etc. (power supply for the input
devices).
Note: Keep the minimum input signal time of
each signal to 0.05s or more.
3. Checking the contacts before use
(PM4H-F only)
When the power ON time is less than the
minimum power application time, the
contacts may remain in an ON state, so
the state of the contacts should be
checked before use. When the contacts
are in an ON state, activating them once
will return them to their normal state (the
OFF state after time-out). (Be aware that
relay characteristics may result in the
contacts being in that same ON state if
exposed to excessive vibration and
impact during transport.)
4. Time setting
To set the time, turn the set dial to a
desired time within the range.
Instantaneous output will be on when the
dial is set to “0”.
When the instantaneous output is used,
the dial should be set under “0” range.
(Instantaneous output area)
Note) When power supply is on, the time
range, setting time and operation mode
cannot be changed.
Turn off the power supply or a reset sig-
nal is applied to set the new operation
mode.
If the position is not stable, the timer
might mis-operate.

PRECAUTIONS IN USING THE PM4H SERIES
5. Superimposed surge of power
supply (PM4H series common)
For the superimposed surge of power
supply, the standard waveform is taken
as the standard value for surge-proof
voltage.
If external surge occurs exceeding the
specified value, the internal circuit may
break down. In this case, use a surge
absorption element.
The positive and negative voltages are
applied each five times between the
power pins.
The typical surge absorption elements
include a varistor, a capacitor, and a
diode. If a surge absorption element is
used, use an oscilloscope to see
whether or not the foreign surge exceed-
ing the specified value appears.
6. Acquisition of CE marking
Please abide by the conditions below
when using in applications that comply
with EN61812-1.
1) Overvoltage category III, pollution
level 2
2) This timer employs a power supply
without a transformer, so the power and
input signal terminals are not insulated.
(PM4H-A only)
(1) When a sensor is connected to the
input circuit, install double insulation on
the sensor side.
(2) In the case of contact input, use dual-
insulated relays, etc.
3) The load connected to the output con-
tact should have basic insulation.
This timer is protected with basic insula-
tion and can be double-insulated to meet
EN/IEC requirements by using basic
insulation on the load.
4) Please use a power supply that is pro-
tected by an overcurrent protection
device which complies with the EN/IEC
standard (example: 250 V 1 A fuse, etc.).
5) You must use a terminal socket or
socket for the installation. Do not touch
the terminals or other parts of the timer
when it is powered. When installing or
un-installing, make sure that no voltage
is being applied to any of the terminals.
6) Do not use this timer as a safety cir-
cuit. For example when using a timer in a
heater circuit, etc., provide a protection
circuit on the machine side.

INSTALLING DIN SIZE TIMER
Installations
1. Surface mount
1) For the timers of PM4H and LT4H
series, use the pin type timer. With the
PM4S and QM4H series, only pin-type
timers are available.
2) Put the terminal socket on the board
directly or put it on the DIN rail (Fig. 1).
3) Insert the timer into the terminal sock-
et and fix it with clip (Fig. 2)
4) On DIN rail mounting, mount the timer
on the DIN rail tightly to get the proper
dimension (Fig. 3).
5) 8-pin type should be connected with
terminal socket (AT8-DF8K). 11-pin type
should be connected with terminal sock-
et (AT8-DF11K).
6) DIN rail (AT8-DLA1) is also available
(1 m).
2. Flush mount
1) For the timers of PM4H and LT4H
series, it is recommended to use the
built-in screw terminal type for flush
mount. (Mounting frame and rubber
gasket are provided when timer is
shipped.)
If the pin type is used, the mounting
frame (AT8-DA4) and rubber gasket
(ATC18002 for surface waterproofing)
that are available at extra costs are nec-
essary. If the pin connection socket is
the 8-pin type, use the 8P cap (AD8-
RC); or if it is the 11-pin type, use the
11P cap (AT8-DP11).
2) How to mount the timer
From the panel front, pass the timer
through the square hole. Fit the mount-
ing frame from the rear, and then push it
in so that the clearance between the
mounting frame and the panel surface is
minimized. In addition, lock the mount-
ing frame with a screw.
3) Caution in mounting the timer
• PM4H, and LT4H series
a If the PM4H and the LT4H series are
used as the waterproof types, tighten the
reinforcing screws on the mounting
frames so that the timers, the rubber
gaskets, and the panel surfaces are
tightly contacted with each other.
(Tighten the two screws with uniform
force and make sure that there is no rat-
tling. If the screws are tightened too
excessively, the mounting frame may
come off.)
b If the timer is installed with the panel
cover and the rubber gasket removed,
the waterproofing characteristic is lost.
4) Installation
Loosen the screws on the mounting
frame, spread the edge of frame and
remove it.
Pull the mounting
frame backward while
spreading out its hooks
with your thumbs and
index fingers.
5) Correctly connect the pins while see-
ing the pin connection diagram.
Tighten the terminal screws with a torque
of 0.8 N·cm or less. The screws are
M3.5. (screw-tightened terminal type)
6) If the pin type is used, the rear termi-
nal block (ATC78041) or the 8P cap
(AD8-RC) is necessary to connect the
pins. For the 11-pin type, use the rear
terminal block (ATC78051) or the 11P
cap (AT8-DP11) and avoid directly sol-
dering the round pins on the timer.
7) Panel cutout dimensions
The standard panel
cutout dimensions are
shown in the left figure.
(Panel thickness: 1 to 5
mm .039 to .197 inch)
8) Although the
timers can be
mounted adjacent
to each other in
this case, it is rec-
ommended to
arrange the
mounting holes
as shown in the
right figure to
facilitate attaching
and detaching the
mounting frame.
9) Adjacent
mounting
Although the
timers can be
mounted adjacent to each other, remem-
ber that the panel surface of PM4H or
LT4H series timer will lose its water-
resistant effect. (Panel thickness: 1 to 5
mm .039 to .197 inch)
A = (48 ×n – 2.5) (mm)
When lining up the
timers horizontally,
set the frames in
such a position so
the formed spring
areas are at the
top and bottom.
When lining up the
timers vertically,
set the frames in
such a position as
the formed spring
areas are at the
right and left.

ON-DELAY TIMER BASIC CIRCUIT
1. Delay Operation (Instantaneous
input)
When control switch A is pressed, timer
T starts immediately and after t-time
elapses, load L is turned ON. When B is
pressed, timer T is reset and load L is
turned OFF.
4. Fixed Time Operation (Continuous
input)
When switch A is closed, load L is turned
ON and after t-time elapses, the load is
turned OFF. When switch A is opened,
timer T is reset and load L is turned OFF.
5. Delay Reset Operation
When contact A is reversed, load L is
immediately turned ON. When contact A
is returned to normal state, load L is
turned OFF after t-time elapses.
This circuit is used when the power sup-
ply is kept ON at all times or used for off-
delay-like application.
However, it can not be used as off-delay
timer at the time of power failure.
6. Fixed Time Operation after Delay
Time is Set (Instantaneous input)
When control switch A is pressed, load L
is turned ON after t1-time elapses, and
load L is turned OFF after t2-time elapses.
This circuit is used for the case of instan-
taneous input (one pulse).
3. Fixed Time Operation
(Instantaneous input)
When control switch A is pressed, load L
is immediately turned ON, and after t-
time elapses, load L is turned OFF.
2. Delay Operation (Continuous input)
When switch A is pressed, after t-time
elapsed, the timer contact closes and
load L is turned ON. When switch A is
opened, the timer is reset and the load is
turned OFF.

• What is the timer?
The timer is a relay having such an out-
put (with or without contact) which elec-
trically closes (turns ON) or opens (turns
OFF) the circuit after a preset time elaps-
es when electrical or mechanical input is
given.
• On-delay Operation (Time delay
operation)
The on-delay operation is an operation to
give output when preset time expires
after a predetermined input is given to
the power supply circuit or input circuit.
On-delay operation includes power sup-
ply on-delay operation and signal on-
delay operation.
TIMER-RELATED TERMINOLOGY
• Off-delay Operation (Time delay
resetting)
The off-delay operation is an operation to
turn OFF output when preset time
expires after a predetermined input is
given to the power supply circuit or input
circuit, and at the same time output sig-
nal is given and predetermined input is
turned OFF. Off-delay operation
includes power supply off-delay opera-
tion and signal off-delay operation.
• Flicker Operation
The flicker operation is an operation to
repeat output ON/OFF action according
to preset ON time and OFF time while a
predetermined input is given to the
power supply circuit or input circuit.
Flicker operation includes OFF-start flick-
er operation and ON-start flicker opera-
tion.

• Preset Time
The preset time is the control time set by
setting time-variable timer.
• Operating Time
The operating time means the time
which elapses between the addition of
predetermined input to the power supply
circuit and input circuit and the comple-
tion of operation for preset time.
• Hold Time
It means the time which elapses
between the completion of operation for
preset time and the start of resetting.
• Pause Time
It means the time elapses between the
start of operation for preset time and the
addition of input required again for the
power supply circuit or input circuit.
Timer does not perform normal function
unless this pause time is set longer than
the timer reset time.
• Resetting
It means that the operation returns to the
state before starting while the timer is in
operation for preset time or after it com-
pletes the operation for preset time.
Resetting during the operation for preset
time is referred to as halfway resetting.
• Reset Time
It means the time elapses between shut-
off of input to the power supply circuit or
input of reset signal and the completion
of resetting.
Timer resetting function shares the reset
of contact, reset of mechanical parts
such as pointer etc., reset of parts in
internal circuit such as capacitor etc.,
and the value at which all of these parts
complete their resetting operation is
regarded as reset time. If timer is used
for a pause time shorter than specified
reset time, the operation time expires
earlier than preset, unexpected instanta-
neous operation takes place or the oper-
ation is failed, thus making it impossible
• Minimum Power Application Time
It means the minimum time during which
power must be supplied in order to oper-
ate timer normally, in the case of power
supply off-delay timer.
• Fluctuation of Operating Time
It means the irregularity in operating time
caused when timer is set at specified
time and the operation is repeated under
the same conditions. It is also referred
to as repetitive error.
• Voltage Error
It means the difference between the
operating time at the rated voltage and
that within the allowable voltage range.
• Temperature Error
It means the difference between the
operating time at the temperature of
20±2°C and that within the allowable
temperature range.
• Set Error
It means the difference between the set
time and the time which actually elapses.
It is also referred to as setting error.
The set error of an analog timer is the
rate to the full-scale value. If the set error
is ±5%, it becomes equivalent to an error
of maximum ±5 hours on the assumption
that 100 hours is set in the range of 100
hours. The error produced when 10
hours is set is also equivalent to an error
of maximum ±5 hours. As far as the set
error is concerned, digital timer is by far
exact. Select a digital timer for the case
when accuracy is required.
When using an analog type multi-range
timer for setting of long time, the setting
procedure stated as follows minimizes
the error. For example, if you want to set
8 hours in the range of 10 hours, first set
the pointer to such a graduation where
the actual operating time should become
as close to 8 seconds as possible in the
range of 10 seconds. Then, reset the
range to 10 hours, leaving the pointer set
at the graduation as it is.
• Star ( )/Delta () Operation
This operation controls the time in the
star connection used for star-delta start-
ing which is conducted for starting a
cage induction motor and the time for
switching the star connection over to
delta connection.
to expect the normal operation.
Therefore, be sure to set the timer pause
time longer than the specified reset time.
9
• Pause Time Error
It means the difference between the operating time to a fixed pause time and the operating time to a pause time that varies.
The pause time characteristics are the main characteristics of CR timer (timer exploiting charge and discharge of capacitor C and
resistance R).
If the oscillation count timer (timer which comprises an oscillation circuit composed of CR and quartz and is operated by a counting
circuit inside IC or micro-computer which counts the reference signal) is used, the pause time error becomes almost negligible owing
to its principles of operation. Accordingly, the description about these characteristics may be omitted for the oscillation count timer.
• Equation for Each Error and Measurement Conditions
The operation time shall be measured, in principle, for retention time of 0.5 second and halt time of 1 second.
The measurement shall be repeated five times except for the initial test. The equation for each error and the measurement condi-
tions are shown in the table below:
Note 1: For digital timers, the set value Ts shall be optional.
Note 2: If no question arises from evaluation results, 13-35°C is acceptable.
Note 3: The measurement may be performed in other specified voltage ranges.
Note 4: The measurement may be performed in other specified temperature ranges.
TM: Average of measured values for operation time
Ts: Set value
TMs: Full-scale value. For digital timers, any arbitrary scale-value may be used.
Tmax: Maximum of measured values for operation time
Tmin: Minimum of measured values for operation time

• Functional Vibration Resistance
Means such a vibration as occurs in the
range where the contact closed with that
vibration during the use of the timer
remains closed for the specified time (3
or 1 msec.) minimum.
• Destructive Vibration Resistance
Means such a vibration as occurs in the
range where no part is damage with that
vibration during the transportation or use
of the timer and the operation character-
istics are maintained.
• Functional Shock Resistance
Means such a shock as occurs in the
range where the contact closed with that
shock during the use of the timer
remains closed for the specified time (1
ms) minimum.
• Destructive Shock Resistance
Means such a shock as occurs in the
range where no part is damaged with
that shock during the transportation or
use of the timer and the operation char-
acteristics are maintained.
• Mechanical life
Means the durability that is achieved
when the control output is performed in
the no-load state.
• Electrical life
Means the durability that is achieved
when the specified voltage and current
loads are individually applied to the con-
trol output while being turned ON and
OFF. Generally, the life of the timer is
represented by the number of times the
control output is performed. When a
load is connected to the control output,
the term of "electrical life" is used. When
no load is connected to the control out-
put, the term of "mechanical life" is used.
The electrical life is shorter than the
mechanical life, and becomes longer as
the load decreases. The life of the timer
is made longer by connecting a relay or
a similar part rather than directly switch-
ing a large load with the control output.
• Rated power consumption
Means the power that is consumed when
the rated operation voltage is applied to
the power circuit.
(Rated power consumption = rated volt-
age ×current consumption)
• Rated control capacity
Means the reference value that is used
to determine the performance of the
switching part of the load. This value is
represented by the combination of volt-
age and current.
• Contact resistance
Means the combined resistance that
consists of the contact resistance
between contacts, and the conductor
resistance of pins and contact springs.
• Insulation resistance
Means the resistance between a contact
or a conductive pin like the pin to which
the operation voltage is applied, and a
dead pin or a non-conductive metallic
part like the time case, the base, or a
retaining screw; or the resistance
between contacts.
• Withstand voltage
Means the limit value that does not
cause breakdown when high voltage is
applied for one minute to the same loca-
tion as measured for insulation resis-
tance. The detectable leak current is
normally 10 mA. In special cases, how-
ever, it may be 1mA or 3 mA.
• Withstand surge voltage
Means the limit value that shows the
durability against momentary abnormal
voltage resulting from lightning or switch-
ing a conductive load. The surge wave-
form is represented by the standard
impulsive voltage waveform at ±(1.2 ×
50) µs or ±(1 ×40) µs.

PRECAUTIONS IN USING THE TIMERS
Cautions for circuits
1. Protective circuit for timer contact
In the circuit that switches an inductive load, a contact failure may occur at a contact point due to surge or inrush current resulting
from that switching. Therefore, it is recommended that the following protective circuit be used to protect the contact point.
2. Type of Load and Inrush Current
The type of load and its inrush current
characteristics, together with the switch-
ing frequency are important factors
which cause contact welding.
Particularly for loads with inrush cur-
rents, measure the steady state current
and inrush current and use a relay or
magnet switch which provides an ample
margin of safety. The table below shows
the relationship between typical loads
and their inrush currents.

When you want large load and long life
of the timer, do not control the load direct
with a timer. When the timer is designed
to use a relay or a magnet switch, you
can acquire the longer life of the timer.
3. Connection of input
The PM4H and LT4H series use power
supply without a transformer (power and
input terminals are not insulated). In
connecting various kinds of input signals,
therefore, use a power transformer in
which the primary side is separated from
the ungrounded secondary side as
shown in Fig. A, for the power supply for
a sensor and other input devices so that
short-circuiting can be prevented.
Do not use a single coil transformer
(e.g., Sly-Duck). Otherwise, the internal
circuit of the timer will be short-circuited
as shown in Fig. B resulting in break-
down.
4. Long Continuous Current Flow
Long continuous current flow through the
timer (approx. one month or longer)
cause generation of heat internally,
which degrade the electronic parts. Use
the timer in combination with a relay and
avoid long continuous current flow
through the timer.

5. Leakage current
1) For connecting and disconnecting
operating voltage to the timer, a circuit
should be used, which will prevent the
flow of leakage current. For example, a
circuit for contact protection as shown in
Fig A. will permit leakage current flow
through R and C, causing erroneous
operation of the timer. Instead, the cir-
cuit shown in Fig. B should be used.
Type of load Inrush current
Resistive load Steady state current
Solenoid load 10 to 20 times the steady state current
Motor load 5 to 10 times the steady state current
Incandescent lamp load 10 to 15 times the steady state current
Mercury lamp load 1 to 3 times the steady state current
Sodium vapor lamp load 1 to 3 times the steady state current
Capacitive load 20 to 40 times the steady state current
Transformer load 5 to 15 times the steady state current

If the load is a relay or solenoid, the release time lengthens.
Effective when connected to both contacts if the power supply voltage is
24 or 48 V and the voltage across the load is 100 to 200 V.
If the load is a timer, leakage current
flows through the CR circuit causing
faulty operation.
Note: If used with AC voltage, be sure
the impedance of the load is sufficiently
smaller than that of the c and r.
As a guide in selecting r and c,
c: 0.5 to 1 µF per 1 A contact current
r: 0.5 to 1 Ωper 1 V contact voltage
Values vary depending on the properties of the load and variations in timer character-
istics.
Capacitor c acts to suppress the discharge the moment the contacts open. Resistor r
acts to limit the current when the power is turned on the next time. Test to confirm.
Use a capacitor with a breakdown voltage of 200 to 300 V. Use AC type capacitors
(non-polarized) for AC circuits.
—
The diode connected in parallel caus-
es the energy stored in the coil to
flow to the coil in the form of current
and dissipates it as joule heat at the
resistance component of the induc-
tive load.
This circuit further delays the release
time compared to the CR circuit.
(2 to 5 times the release time listed in
the catalog)
Use a diode with a reverse break-
down voltage at least 10 times the
circuit voltage and a forward cur-
rent at least as large as the load
current.
In electronic circuits where the cir-
cuit voltages reverse breakdown
voltage of about 2 to 3 times the
power supply voltage.
Using the rated voltage characteris-
tics of the varistor, this circuit pre-
vents excessively high voltages
from being applied across the con-
tacts. This circuit also slightly
delays the release time.

2) If the timer is directly switched with a
non-contact element, leak current may
flow into the timer and cause it to mal-
function.
6. Power off time
If the operation voltage for the timer is
turned ON after the limit time operation is
completed or before the limit time is
reached, the Power off time longer than
the timer restoration time must be
secured.
7. Suicide circuit
If the timer is restored immediately after
the specified time is reached, the circuit
must be configured so that the restora-
tion time of the timer can be secured suf-
ficiently.
If the power circuit for the timer is turned
OFF with the timer contact, a suicide cir-
cuit may be configured (Fig. A). In order
to settle the problem with this potential
suicide circuit, the circuit must be
designed so that the timer is turned OFF
after the self-retention circuit is com-
pletely released (Fig. B).
tion:
(1) If an AC load is switched in synchro-
nized phases:
Locking or welding is liable to occur due
to contact transposition. Check this with
the actual system.
(2)If a load is switched very frequently:
If a load which generates arcs when a
contact is switched is turned ON and
OFF very frequently, nitrogen and oxy-
gen in air are combined due to arc ener-
gy and then HNO3is produced. This
may corrode metallic materials.
The effective countermeasures include:
1. Using an arc-extinguishing circuit;
2. Decreasing the switching frequency;
and
3. Decreasing the humidity in the ambi-
ent atmosphere.

8. Electrical life
The electrical life varies depending on
the load type, the switching phase, and
the ambient atmosphere. In particular,
the following cases require careful atten-
Cautions for use
(common for all models)
1. Pin connections
Correctly connect the pins while seeing
the terminal layout/wiring diagram. In
particular, the DC type, which has polari-
ties, does not operate with the polarities
connected reverse. Any incorrect con-
nection can cause abnormal heating or
ignition.
2. Connection to operation power supply
1) Supply voltage must be applied at a
time through a switch, a relay, and other
parts. If the voltage is applied gradually,
the specified time may be reached
regardless of its value or the power sup-
ply may not be reset.
2) The operation voltage for the DC type
must be at the specified ripple percent-
age or less. The average voltage must
fall within the allowable operation voltage
range.
Note: Refer to the ripple percentage of each timer.
3) Make sure that no induced voltage
and residual voltage are applied between
the power pins on the timer after the
power switch is turned OFF.
(If the power line is wired in parallel with
the high-voltage and motor lines,
induced voltage may be produced
between the power pins.)
3. Control output
1) The load for the control output must
be used within the load capacity speci-
fied in the rated control capacity. If it is
used exceeding the rated value, the life
is greatly shortened.
4. Installing the timer
1) To install the timer, use the dedicated
pin bracket or socket (cap). Avoid con-
necting the pins on the timer by directly
soldering them.
2) In order to maintain the characteris-
tics, do not remove the timer cover
(case).
5. Superimposed surge of power sup-
ply
For the superimposed surge of power
supply, the standard waveform (±1.2 ×
50µs or ±1 ×40µs) is taken as the stan-
dard value for surge-proof voltage. (The
positive and negative voltages are
applied each three or five times between
the power pins.)
For the standard values for the PM4H,
LT4H and S1DX type timers, see the
respective items in "Cautions for use."
If external surge occurs exceeding the
specified value, the internal circuit may
break down. In this case, use a surge
absorption element. The typical surge
absorption elements include a varistor, a
capacitor, and a diode. If a surge
absorption element is used, use an oscil-
loscope to see whether or not the foreign
surge exceeding the specified value
appears.
6. Changing the set time
Do not change the set time when the
limit time operation is in progress.
However, this is possible only with the
motor-driven type timer if the set time is
shorter than the remaining time. For
changing the set time on the digital timer
(LT4H series), see the relevant item in
"Cautions for use."

PRECAUTIONS IN USING THE TIMERS
2) The following connection might result
in short circuit between the heteropolar
contacts in the timer.
12
7. Operating environment
1) Use the timer within the ambient tem-
perature range from –10°C to +50°C
+14°F to +122°F (+55°C +131°F for the
LT4H series) and at ambient humidity of
85% RH maximum.
2) Avoid using the timer in a location
where inflammable or corrosive gas is
generated, the timer is exposed to much
dust and other foreign matter water or oil
is splashed on the timer or vibrations or
shocks are given to the timer.
3) The timer cover (case), the knobs,
and the dials are made of polycarbonat-
ed resin. Therefore, prevent the timer
from being exposed to organic solvents
such as methyl alcohol, benzine, and
thinner, strong acid substances such as
caustic soda, and ammonia and avoid
using the timer in atmosphere containing
any of those substances.
4) If the timer is used where noises are
emitted frequently, separate the input
signal elements (such as a sensor), the
wiring for the input signal line, and the
timer as far as possible from the noise
source and the high power line contain-
ing noises.
8. Checking the actual load
In order to increase the reliability in the
actual use, check the quality of the timer
in the actual usage.
9. Others
1) If the timer is used exceeding the rat-
ings (operation voltage and control
capacity), the contact life, or any other
specified limit, abnormal heat, smoke, or
ignition may occur.
2) If any malfunction of the timer is likely
to affect human life and properties, give
allowance to the rated values and perfor-
mance values. In addition, take appro-
priate safety measures such as a duplex
circuit from the viewpoint of product lia-
bilities.

FOREIGN SPECIFICATIONS OVERVIEW
4. Shipping Standards
(1) Lloyd’s Register of Shipping
Standards from the Lloyd’s Register shipping asso-
ciation based in England. These standards are
safety standards for environmental testing of the
temperature and vibration tolerances of electrical
components used for UMS (unmanned machine
rooms in marine vessels) applications. These stan-
dards have become international standards for
control equipment in all marine vessel applications.
No particular action is taken to display the confor-
mation to these standards on the products.
1. International Standards
IEC standard
International Electrotechnical Commission
By promoting international cooperation toward all
problems and related issues regarding
standardization in the electrical and electronic
technology fields, the IEC, a non-governmental
organization, was started in October, 1908, for the
purpose of realizing mutual understanding on an
international level. To this end, the IEC standard
was enacted for the purpose of promoting
international standardization.
2. North America
UL (Underwiters Laboratories Inc.)
This is a non-profit testing organization formed in
1894 by a coalition of U.S. fire insurance firms,
which tests and approves industrial products
(finished products). When electrical products are
marketed in the U.S., UL approval is mandated in
many states, by state law and city ordinances. In
order to obtain UL approval, the principal parts
contained in industrial products must also be UL-
approved parts.
UL approval is divided into two general types. One
is called “listing” (Fig. 1), and applies to industrial
products (finished products). Under this type of
approval, products must be approved
unconditionally. The other type is called
“recognition” (Fig. 2), and is a conditional approval
which applies to parts and materials.
CSA (Canadian Standards Association)
This was established in 1919 as a non-profit, non-
governmental organization aimed at promoting
standards. It sets standards for industrial products,
parts, and materials, and has the authority to judge
electrical products to determine whether they
conform to those standards. The CSA is the ultimate
authority in the eyes of both the government and the
people in terms of credibility and respect. Almost all
states and provinces in Canada require CSA
approval by law, in order to sell electrical products.
As a result, electrical products exported from Japan
to Canada are not approved under Canadian laws
unless they have received CSA approval and
display the CSA mark. Approval is called
“certification”, and products and parts which have
been approved are called “certified equipment”, and
display the mark shown in Fig. 3. The mark shown
in Fig. 4 is called the “Component Acceptance”
mark, and indicates conditional approval which is
applicable to parts. The C-UL mark shown in Fig. 5
(finished products) and Fig. 6 (parts) indicates that
the product has been tested and approved in UL
laboratories, based on UL and CSA standards,
through mutual approval activities.
3. Europe
EN standard
European Standards/Norme Europeennee
(France)/Europaishe Norm (Germany)
Abbreviation for European Standards. A unified
standard enacted by CEN/CENELEC (European

nations employ the content of the EN standards into
their own national standards and are obligated to
abolish those national standards that do not agree
with the EN standards.
(1) Germany
VDE (Verband Deutscher Elektrotechniker)
The VDE laboratory was established mainly by the
German Electric Technology Alliance, which was
formed in 1893. It carries out safety experiments
and passes approval for electrical devices and
parts. Although VDE certification is not enforced
under German law, punishment is severe should
electrical shock or fire occur; therefore, it is, in fact,
like an enforcement.
TÜV (Technischer Überwachungs-Verein)
TÜV is a civilian, non-profit, independent
organization that has its roots in the German Boiler
Surveillance Association, which was started in 1875
for the purpose of preventing boiler accidents. A
major characteristic of TÜV is that it exists as a
combination of 14 independent organizations (TÜV
Rheinland, TÜV Bayern, etc.) throughout Germany.
TÜV carries out inspection on a wide variety of
industrial devices and equipment, and has been
entrusted to handle electrical products, as well, by
the government. TÜV inspection and certification is
based mainly on the VDE standard.
TÜV certification can be obtained from any of the 14
TÜVs throughout Germany and has the same
effectiveness as obtaining VDE certification.

CE MARKINGS OVERVIEW
Counter, Hour Meter conforming to
EN/IEC standards
The Timer, Counter, Hour Meter shown below conform to both EN and IEC standards,
and may display the CE markings.
CE markings and EC
directives
The world’s largest single market, the
European Community (EC) was born on
1 January 1993 (changing its name to
EU in November 1993. It is now always
expressed as EU, apart from EC direc-
tives.) EU member country products
have always had their quality and safety
guaranteed according to the individual
standards of each member country.
However, the standards of each country
being different prevented the free flow of
goods within the EU. For this reason, in
order to eliminate non-tariff barriers due
to these standards, and to maximize the
merits of EU unification, the EC direc-
tives were issued concomitant to the
birth of the EU.
The EN standards were established as
universal EU standards in order to facili-
tate EU directives. These standards
were merged with the international IEC
standards and henceforth reflect the
standards in all countries. Also, the CE
markings show that products conform to
EC directives, and guarantee the free
flow of products within the EC.
Appropriate
EC directives for control
equipment products
The main EC directives that are to do
with machinery and electrical equipment
are the machinery directive, the EMC
directive, the low voltage directive, and
the telecom directive. Although these
directives have already been issued, the
date of their enactment is different for
each one. The machinery directive was 1
January 1995. The EMC directive was 1
January 1996, and the low voltage direc-
tive was enacted from 1 January 1997.
The telecom directive was established by
the separate CTR (Common Technology
References.)
What are EN standards?
An abbreviation of Norme Europeenne
(in French), and called European
Standards in English. Approval is by vote
among the CEN/CENELEC member
countries, and is a unified standards
limited to EU member countries, but the
contents conform to the international
ISO/IEC standards.
