H7CC-

• 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) of

the Counter (Tachometer), 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 following diagram (DC

power supplies only).

• 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.

• 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.

• When conforming to EMC standards, refer to the information

provided in this datasheet 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.

• Basic insulation is provided between power supply and input

terminals, between power supply and output terminals, and

between input and output terminals.

• When double insulation or reinforced insulation is required, apply

double insulation or reinforced insulation as defined in IEC 60664

that is suitable for the maximum operating voltage with clearances

or solid insulation.

• Connect the input and output terminals to devices that do not have

any exposed charged parts.
