Operation
■Count Operation
Preset Counters
Note: Two-stage counters, set the counters so that the interval between 1st and 2nd count out will be more than 5 ms. For Incrementing/
Decrementing switchable counters, only the 2nd value will be effective if the 1st value is larger than the 2nd value.
The Incrementing/Decrementing Counters give outputs in the following order; 1st to 2nd to 1st to 2nd.
Totalizing Counters
Note: The count value will return to “0” when it reaches the full scale limit.
* The full scale value is 9999 for the 4-digit counters, 999999 for the 6-digit counters, and 99999999 for the 8-digit counters.

Note: 1. A: Minimum signal width; B: Must be at least 1/2 of minimum signal width. An error of ±1 count may occur if the width of (A) and (B) are
smaller than the minimum signal width.
2. Set the same counting speed for CP1 and CP2 when in Up/Down C, or F mode.
■Output Modes
Note: 1. In the C, K, P, and Q modes, the counters must not count out again while the one-shot timer is working.
2. In the C mode, the present value is placed in reset start status as soon as the preset count is reached and the count-out status is not
displayed.

Note: 1. The polarities of the DC power supply terminals are as
follows:
Terminal 1: negative; terminal 2: positive
2. If there is excessive external noise, terminal 3 must be
grounded to an appropriate place where the grounding
resistance is 100 Ω max. There will be a current leakage
of 0.2 mA each from terminals 1 and 2 to terminal 3.
3. The open terminals cannot be used as relay terminals.
4. Insert surge absorbers between each of the power
supply terminals and the ground terminal. If the ground
terminal is not used, insert the surge absorbers between
terminal 1 and terminal 2.

Contact Inputs
For contact inputs, the contact must have a switching capacity of
2.5 mA min. at 12 V. If a 680-W resistor (1/2 W) is used for R4,
reliability will be improved.
Connections of Single Transistor Inputs
The following illustrations show how to connect a single transistor input to digital counters connected in parallel. The H7AN has an input resistance
of 4.7 kW. If the number of counters is N, the total input resistance will be 4.7/N kW. In this case, the high level input signal voltage can be calculated
as follows:
(4.7/N) x E/(4.7/N + R)
Determine the value of E (V) and R (kW) so that the high level input signal voltage will be 5 to 30 VDC.
Connections of Single Contact Inputs
The following illustrations show how to connect a single contact input to digital counters connected in parallel. If the number of digital counters is
N, the total contact input current will be 2.5 x N (mA) at 12 VDC.

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
•Make sure the proper product is specified for the application.
•For correct use, do not subject the timer 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 7.2 mm
max.) for wiring with a gage of AWG 24 to AWG 18 (equal to a
cross section area of 0.205 to 0.823 mm2).
(The wiring stripping length is 5 to 6 mm.) 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.
•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.
•Do not apply the supply voltage directly from external to transistor
output.
•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. (If a setting switch is accidentally touched
during operation, the set value will be changed and the new set
value will be used for operation. Always leave the front panel cover
closed unless you are changing a setting.)
•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.
•Turn the power OFF first when removing the body from the case,
never touch the terminals or electronic components with your
hands or subject them to shock. When inserting the body, do not
allow electronic components to come in contact with the case.
•Static electricity may destroy internal components. When removing
the body form the case, do not touch an electronic components
other than the setting switches with your hands.
CAUTION
Indicates a potentially hazardous
situation which, if not avoided, may
result in minor or moderate injury or in
property damage.

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.
CAUTION
Do not touch the terminals while power is being
supplied. Doing so many 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 terminal 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 or filings from installation to enter the
product. Doing so may occasionally result in electric
shock, fire, or malfunction.

•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.
•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.23 A for 264 VAC
12 to 24 VDC specifications Approx.15 A for 26.4 VDC
•After turning ON the power supply, 50 ms is required for the internal
circuits to reach the operating voltage. Operation for input signals
may not be correctly during this time.
•After turning OFF the power supply, 50 ms is required for voltage in
the internal circuits to drop. Operation may be performed for input
signals during this time.
•Models without power failure memory backup or models ending
with "-M" (when memory backup is disabled) 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) and enable memory backup if holding the
status before the power failure is required when the power is
interrupted.
•The following timing chart shows how the H7AN indicates when
there is an external or manual reset input.
•To mount the casing on the digital counter, insert the digital counter
body into the casing by hand as far as possible and then tighten the
mounting screw. Press by the hand the front panel as indicated by
the arrow so that the screw will tighten securely.
Retaining Data during Power
Interruptions
•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. (-M type
only)
■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.

This product was upgraded in January 2006. The main changes are
described below.
1. Maximum Counting Speeds
A DIP switch on models with 4, 6, or 8 digits could be used to set
the maximum counting speed to 3 kHz, 5 kHz, or 30 kHz. The
upgraded models have been changed so the maximum counting
speed can be set to 5 kHz or 30 kHz.
2. Addition of Setting to Enable/Disable Data Backup for Power
Interruptions
On models that back up data when power is turned OFF (models
with model numbers ending in “-M”), a DIP switch setting has
been provided to enable or disable backup.
3. Changes in Functions Allocated to Function Setting Switches
Some of the functions allocated to the DIP switches have been
changed to allow for the changes described in 1 and 2, above.
In the interest of product improvement, specifications are subject to change without notice.

disclaims all other warranties, express or implied.
(b) Limitations. OMRON MAKES NO WARRANTY OR REPRESENTATION, EXPRESS OR IMPLIED, ABOUT
NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OF THE PRODUCTS. BUYER

Omron’s election, to (i) replace (in the form originally shipped with Buyer responsible for labor charges for removal or
replacement thereof) the non-complying Product, (ii) repair the non-complying Product, or (iii) repay or credit Buyer an amount
equal to the purchase price of the non-complying Product; provided that in no event shall Omron be responsible for warranty,
repair, indemnity or any other claims or expenses regarding the Products unless Omron’s analysis confirms that the Products
were properly handled, stored, installed and maintained and not subject to contamination, abuse, misuse or inappropriate
modification. Return of any Products by Buyer must be approved in writing by Omron before shipment. Omron Companies shall

Limitation on Liability; Etc.

Suitability of Use.
Omron Companies shall not be responsible for conformity with any standards, codes or regulations which apply to the
combination of the Product in the Buyer’s application or use of the Product. At Buyer’s request, Omron will provide applicable
third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself
is not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine,
system, or other application or use. Buyer shall be solely responsible for determining appropriateness of the particular Product
with respect to Buyer’s application, product or system. Buyer shall take application responsibility in all cases.

Omron Companies shall not be responsible for the user’s programming of a programmable Product, or any consequence
thereof.
Performance Data.

suitability and does not constitute a warranty. It may represent the result of Omron’s test conditions, and the user must correlate
it to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations of Liability.
Change in Specifications.
Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our
practice to change part numbers when published ratings or features are changed, or when significant construction changes are
made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers
may be assigned to fix or establish key specifications for your application. Please consult with your Omron’s representative at
any time to confirm actual specifications of purchased Product.
