SAFETY PRECAUTIONS
Keys to Warning Symbols
Indicates a potentially hazardous situation which, if not
CAUTION avoided, is likely to result in minor or moderate injury or
in property damage.
CAUTION
Doing so may occasionally result in electric shock, fire, or malfunction. Do not allow pieces of metal, wire clippings, or fine metallic shavings or fillings from installation to enter the product.
Minor injury due to explosion may occasionally occur. Do not use the Tachometer where subject to flammable or explosive gas.
Fire may occasionally occur. Tighten the terminal screws to the rated torque. P2CF Socket terminals: 4.4 lb-in (0.5 Nm) P3GA-11 Socket terminals: 6.55 to 7.97 lb-in (0.74 to 0.90 Nm)
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 Tachometer or touch internal components.

Precautions for Safe Use

When mounting the Tachometer to a panel, tighten the two mounting screws alternately, a little at a time, so as to keep them at an equal tightness. If the panel screws are tightened unequally, water may enter the panel.
Store the Tachometer at the specified temperature. If the Tachometer has been stored at a temperature of less than -10°C, allow the Tachometer to stand at room temperature for at least 3 hours before use.
Mounting the Tachometer side-by-side may reduce the life expectancies of internal components. 4) Use the Tachometer within the specified ranges for the ambient operating temperature and humidity. 5) Do not use in the following locations:
Locations subject to sudden or extreme changes in temperature. Locations where high humidity may result in condensation. Locations with excessive vibration or shock. Locations subject to water. Locations subject to oil. Locations prone to icing. Locations subject to exposure chemicals. Locations subject to bugs and small animals 6) Do not use this Tachometer in dusty environments, in locations where corrosive gasses are present, or in locations subject to direct sunlight. 7) Install the Tachometer well away from any sources of static electricity, such as pipes transporting molding materials, powders, or liquids. 8) Internal elements may be destroyed if a voltage outside the rated voltage range is applied. 9) Be sure that polarity is correct when wiring the terminals. 10) Separate the Tachometer from sources of noise, such as devices with input signals from power lines carrying noise, and wiring for I/O signals. 11) Do not connect more than two crimp terminals to the same terminal. 12) Up to two wires of the same size and type can be inserted into a single terminals. 13) Use the specified wires for wiring. Applicable Wires: AWG 18 to AWG 22, solid or twisted, copper 14) Install a switch or circuit breaker that allows the operator to immediately turn OFF the power, and label it to clearly indicate its function. 15) When the Tachometer is operated with no-voltage input (NPN input), approximately 14 V is output from the input terminals. Use a sensor that contains a diode. 16) Use a switch, relay, or other 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 Tachometer may malfunction or outputs may be unstable. 17) Use a switch, relay, or other contact to turn the power supply OFF instantaneously. Outputs may malfunction and memory errors may occur if the power supply voltage is decreased gradually. 18) When changing the comparison value during operation, because the H7CC uses a constant read-in system, the output status will change if the comparison value is changed to a value on the other side of the present value. 19) When the power is turned ON using the factory settings, the output will turn ON after 999.9 s if no pulses are received as count input. 20) Do not use organic solvents (such as paint thinners or benzine), strong alkali, or strong acids. They will damage the external finish. 21) Confirm that indications are working normally, including the backlight LEDs, and LCD. 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. 22) The waterproof packing may deteriorate, shrink, or harden depending on the application environment. Periodic inspection and replacement are required.

Conformance to EN/IEC Standards
When conforming to EMC standards, refer to the information provided in this Instruction Manual for cable selection and other conditions.
This is a class A product. In residential areas it may cause radio interference, in which case the user may be required to take adequate measures to reduce interference.

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 Tachometer 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 Tachometer 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 following diagram (DC power supplies only).

Power supply voltage (VDC)

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 Tachometer 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 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 to run mode.

Dispose of the product according to local ordinances as they apply.
Attach the front panel when using the Tachometer. The tabs in the middle of each of four sides

secure the front panel to the product body. To remove the panel, widen the four tabs and pull the

panel toward you. To mount the panel, fit all four tabs correctly into the grooves on the product

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.

Terminal Arrangement

Wire properly after checking the specifications of the power supply voltage. Do not connect unused terminals.

When Hold operation is performed, Rplc will no longer be displayed even if the alarm set value is exceeded. (Monitoring is possible, however, because the Tachometer 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 Hold 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.
