SAFETY PRECAUTIONS
CAUTION
Do not allow pieces of metal, wire clippings, or fine metallic shavings or
fillings from installation to enter the product. Doing so may occasionally
result in electric shock, fire, or malfunction.|
Minor injury due to explosion may occasionally occur. Do not use the Counter
where subject to flammable or explosive gas.|
Fire may occasionally occur. Tighten the terminal screws to the rated torque.
H7CC terminals and P3GA-11/P3G-08 Socket terminals: 6.55 to 7.97 lb-in (0.74 to 0.90 N·m)
P2CF Socket terminals: 4.4 lb-in (0.5 N·m)
|
Minor injury due to electric shock may occasionally occur. Do not touch any of
the terminals while power is being supplied. Be sure to mount the terminal
cover after wiring.|
The life expectancy of the output relay varies considerably according to its
usage. Use the output relay within its rated load and electrical life
expectancy. If the output relay is used beyond its life expectancy, its
contacts may become fused or there may be a risk of fire. Also, be sure that
the load current does not exceed the rated load current and when using a
heater, be sure to use a thermal switch in the load circuit.|
Minor electric shock, fire, or malfunction may occasionally occur. Do not
disassemble, modify, or repair the Counter or touch internal components.|
- When mounting the Counter to a panel, tighten the two mounting screws alternately, a little at a time, so as to keep them at an equal If the panel screws are tightened unequally, water may enter the panel.
- Store the Counter at the specified If the Counter has been stored at a temperature of less than −10°C, allow the Counter to stand at room temperature for at least 3 hours before use.

- Separate the Counter from sources of noise, such as devices with input signals from power lines carrying noise, and wiring for I/O signals.
- Do not connect more than two crimp terminals to the same
- Up to two wires of the same size and type can be inserted into a single
- Use the specified wires for
Applicable Wires: AWG 18 to AWG 22, solid or twisted, copper
- Install a switch or circuit breaker that allows the operator to immediately turn OFF the power, and label it to clearly indicate its function.
- When the Counter is operated with no-voltage input (NPN input), approximately 14 V is output from the input terminals. Use a sensor that contains a diode.
- Use a switch, relay, or another contact so that the rated power supply voltage will be reached within
0.1 second. If the power supply voltage is not reached quickly enough, the Counter may malfunction or outputs may be unstable.
- Use a switch, relay, or another contact to turn the power supply OFF Outputs may malfunction and memory errors may occur if the power supply voltage is decreased gradually.
- When changing the set value during operation, because the H7CC uses a constant read-in system, output will turn ON if the set value is equal to the present value.
- If the set value and present value are both 0, the output will turn ON for the default The output will turn OFF during a reset operation.
- Do not use organic solvents (such as paint thinners or benzine), strong alkali, or strong They will damage the external finish.
- Confirm that indications are working normally, including the backlight LEDs, and The indicator LEDs, LCD, and resin parts may deteriorate more quickly depending on the application environment, preventing normal indications. Periodic inspection and replacement are required.
- The waterproof packing may deteriorate, shrink, or harden depending on the application Periodic inspection and replacement are required.
Precautions for Correct Use
-
Read this manual carefully before using the product.
-
An inrush current of approx. 10 A will flow for a short time when the power supply is turned ON. If the capacity of the power supply is not sufficient, the Counter may not start. Be sure to use a power supply with sufficient capacity.
-
Make sure the power supply voltage and loads are within the specifications and ratings for the product.
-
To allow for the startup time of peripheral devices (e.g., sensors), start Counter timing operation 200 ms to 290 ms after turning ON the power. The input signal will not be accepted before 200 to 290 ms has elapsed.
-
The input signal will not be accepted after 5 to 1005 ms has elapsed from when the power supply is turned OFF.
-
Inrush current generated by turning ON or OFF the power supply may deteriorate contacts on the power supply circuit. Turn ON or OFF to a device with the rated current of more than 10 A.
-
The capacity of the external power supply is 100 mA at 12 V. When using a 24 VAC/12 to 48 VDC power supply, reduce the load with the power supply voltage, as shown in the diagram (DC power supplies only) on the right.
-
If the prescale value setting is incorrect, a counting error will occur. Check that the settings are correct before using this function.
-
Make sure that all settings are appropriate for the application. Unexpected operation resulting in property damage or accidents may occur if the settings are not appropriate.
-
Do not leave the Counter for long periods at a high temperature with output current in the ON state. Doing so may result in the premature deterioration of internal components (e.g., electrolytic capacitors). Do not install the product close contact with the heating element.
-
Non-volatile memory is used as backup memory when the power is interrupted. The write life of the non-volatile memory is 100,000 writes. The non-volatile memory is written when the power is turned OFF or when switching from function setting mode or configuration selection mode to run mode.
-
Dispose of the product according to local ordinances as they apply.
-
Attach the front panel when using the Counter. The latches in the middle of each of four sides secure the front panel to the main body. To remove the panel, widen the four latches and pull the panel toward you. To mount the panel, fit all four latches correctly into the slots on the main body.
-
Do not use because it may be damaged inside the product when the product fall by mistake.
Confirm the wiring the input and output terminals correctly before power is supplied. -
Do not use the product near radio wave receivers. Doing so may cause incoming radio wave interference.
-
Do not use in a circuit with the waveform is distorted. The error will increase due to the influence of the distorted waveform.
-
Install product so that the load doesn’t span the product body.
Mounting
Front panel dimensions are the same for all models.

Operation as a Counter
Note: Refer to the datasheet for detailed parameter settings. Change from RUN Mode to Function Setting Mode Set the parameters using the UP Key or DOWN Key. The characters displayed in the reverse video are the default settings
Set each digit using the individual UP and DOWN Keys for the following configuration selection modes.
Operation as a Tachometer
- Note: Refer to the datasheet for detailed parameter settings. Change from RUN Mode to Function Setting Mode.
- Set the parameters using the UP Key or DOWN Key. The characters displayed in reverse video are the default settings.
Settings
1-stage preset counter 2-stage preset counter
Total and preset counteract counter Dual counter Twin counter Tachometer Key-protect Switch Settings
When the key-protect switch is ON, ON (enable) individual key operations can be disabled to prevent setting errors according to the key protect levels (KP-1 to KP-7) shown in the following table. Note: Key protect levels are set in function setting mode.
Diagnostic
- This includes times when the life of the non-volatile memory has expired.
- This occurs if the present value or total count value falls below –99999.
- This occurs in the following conditions if the present value (i.e., measurement value) exceeds 999999.
- For Output Modes K-2, D, L, or H
- Dual counter or tachometer operation is used.
- Display flashes. (1-second cycles)
- This does not apply when tachometer operation is used.
- This is displayed if the alarm set value for either of the two outputs is exceeded if a model with two outputs is used. The total ON count will not be cleared by using the Reset operation.
- The normal display and Rplc will appear alternately. When the Reset operation is performed, Rplc will no longer be displayed even if the alarm set value is exceeded. (Monitoring is possible, however, because the Counter will continue without clearing the total run time and the output ON count.)If the power supply is turned OFF/ON after the Rplc display is turned OFF by Reset operation, Rplc will be displayed again. In order to prevent the display even after the power supply is turned OFF/ON, change the alarm set value to equal to or greater than the count value, or change the alarm set value to 0 to be invalid.
