■Protective Cover
The Protective Cover shields the front panel, particularly the count
value setting section from dust, dirt and water, and prevent
malfunctioning of the Counter due to static electricity.
Note: 1. The Hard Protective Cover prevents the set count value
from being altered due to accidental contact with the push-
type thumbwheel switch.
2. The Soft Protective Cover allows the set value to be set by
depressing the thumbwheel switches through it.
It may be, however, difficult to make setting changes of the
Counter with the Y92A-48B Protective Cover attached,
which must be taken into consideration before using the
Y92A-48B Protective Cover.

Note: 1. Make sure that the fluctuation of the supply voltage is within the permissible range.
2. Pay attention to the polarity of the DC power supply and do not make a wiring mistake.

Safety Precautions
●
Be sure to read the precautions for all Counters in the website at: http://www.ia.omron.com/.
Warning Indications
Meaning of Product Safety Symbols
!CAUTION
•Make sure the proper product is specified for the application.
•For correct use, do not subject the product to the following
conditions.
•Dramatic temperature fluctuations
•High humidity or where condensation may occur
•Severe vibration and shock
•Where excessive dust, corrosive gas, or direct sunlight may be
present
•This product is not waterproof or oil resistance. Do not use the
product in any of the places subject to splashing liquid or oil
atmosphere.
•Use and store the product within the rated ranges given for the
product model you are using. If necessary, use forced cooling.
If the product is stored below −10°C, allow it to warm up for three
hours at room temperature before turning ON the power supply.
•Do not cover the vent holes on the products and the area around
the product in order to ensure thermal dissipation.
•Wiring all terminals correctly.
•Do not wire the terminals which are not used.
•Use specified size crimped terminals (M3.5, thickness 7.2mm
max.) for wiring with a gage of AWG 24 to AWG 18 (equal to a
cross section area of 0.205 to 0.823mm2).
(The wiring stripping length is 5 to 6mm.)
Up to two wires of same size and type, or two crimped terminals
can be inserted into a single terminal.
•Use this product within the rated power supply voltage and control
output.
•Use a switch, relay, or other contact to turn the power supply ON
instantaneously. If the voltage is applied gradually, the power may
not be reset or output malfunctions may occur.
•Do not apply the supply voltage directly from external to transistor
output.
•Interlock the power to the product with a relay so that the product
will not be left in an output on condition for long periods. Leaving
the product in an output-on condition for a month or longer,
especially in places with high temperatures, may result in
deterioration to internal parts, such as an electrolytic capacitor.
•A constant reading system is used in the present counter, so
settings can be changed while power is being supplied, but the
output will turn ON if the set value is set to the current
measurement value.
•When changing the set count while power is being supplied, an
inadequate push of the thumb wheel switches will display two
numbers in one display window, causing the operating count to drift
widely. Therefore, press the thumb wheel switches surely.
•Internal circuit voltage (5 V) is output to the no-
voltage input terminals, which may cause some
connected devices to malfunction or fail. Check the
specifications of the input device (e.g., rated output
voltage or whether a power supply circuit diode is
built in).
To prevent power supply devices from being subjected to charging
accidents, connect a diode as in the diagram figure when using a
power supply voltage of 5 V or less to operate input devices that do
not have a diode built into the power supply circuit.
•Check that the LED indicators are operating normally. Depending
on the operating environment, the indicators and plastic parts may
deteriorate faster than expected, causing the indicators to fail.
Periodically perform inspections and replacements.
•Use tools when separating parts for disposal.
•When disposing of the product, observer all local ordinances as
they apply.
CAUTION
Indicates a potentially hazardous
situation which, if not avoided, may
result in minor or moderate injury or in
property damage.

safely.
Precautions for
Correct Use
Supplementary comments on what to
do or avoid doing, to prevent failure to
operate, malfunction or undesirable
effect on product performance.
Used to warn of the risk of electric shock under
specific conditions.
Used for general prohibitions for which there is no
specific symbol.
Used for general mandatory action precautions
for which there is no specified symbol.
Do not touch the terminals while power is being supplied.
Doing so may occasionally result in minor injury due to
electric shock.
Do not use the product where subject to flammable or
explosive gas. Otherwise, minor injury from explosion
may occasionally occur.
Never disassemble, modify or repair the product or touch
any of the internal parts. Minor electric shock, fire, or
malfunction may occasionally occur.
The life expectancy of output relays varies considerably
with the output load and switching conditions. Always
consider the application conditions and use the output
relays within their rated load and electrical life
expectancy. If the output relays are used past their life
expectancy, contact fusing or burning may occasionally
occur. Also, never exceed the rated load current. When
using a heater, surely use a thermo switch in the load
circuit.
Tighten the screws to between 0.74 and 0.90 N⋅m. Loose
screws may occasionally result in fire.
Do not allow pieces of metal, wire clippings, or fine
metallic shavings from installation to enter the product.
Doing so may occasionally result in electric shock, fire, or
malfunction.

•Inrush current will be carried when turning on the power. If the
capacity of the power for the product is insufficient, the product
cannot start. Use a power supply, breakers, contacts which
sufficient capacity.
100 to 240 VAC specifications Approx. 0.8 A for 264 VAC
12 to 48 VDC specifications Approx. 0.4 A for 52.8 VDC
•Since 50 ms after the power is turned ON is required as the raise
time of the internal circuit voltage, note that the product may not
operate in response to any input signal during this period.
•Since 50 ms after the power is turned OFF (or momentary power
failures) is required as the fall time of the internal circuit voltage,
note that the product may respond to input signals during this
period.
•Models without power failure memory backup will operate as shown
in the following figure if the power supply is momentarily
interrupted.
Note: Use a Counter with power failure backup memory (models
ending with -M) if holding the status before the power failure is
required when the power is interrupted.
•All number display digits on the Counter will be OFF when the
signal is input for a external or manual reset. When the reset signal
is completed, the numeric display will show the reset value.
•Model H7CN 12-48 VDC specification use transformerless power
supply which the power terminals and input terminals are not
insulated. When use this specification, the internal parts of the
product may be occasionally burnt (damaged) if the wiring is not
correct. Pay attention to check the wiring before use.
Power Failure Backup Memory
•The product memorizes the status just before occurring the electric
failure memory with non-volatile memory. The rewriting lifespan of
the non-volatile memory is 1,000,000 or more. The non-volatile
memory rewrites the setting condition into the initial setting one
when the power OFF and reset input.
■Self-diagnostic Function
When an error has occurred, the bellow error codes are shown.
* Including the case when the rewriting lifespan of the nonvolatile
memory is reached.
Recovery method
As an action, turn the power OFF then back ON again. If the display
restored to normal, then a probable cause can be external noise
affecting the system. Check for external noise. In the case of e3, if
the display remains the same even when turn power ON again, input
reset. After that, if it still remains the same, the product must be
repaired.

Previously, an external backup battery was required for
Counters with memory backup, but the Counter has been
upgraded so that the external battery is no longer necessary.
