H7CC-

• 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

tightness. If the panel screws are tightened unequally, water may

enter the panel.

• Store the Counter at the specified temperature. 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.

• Mounting the Counter side-by-side may reduce the life

expectancies of internal components.

• Use the Counter within the specified ranges for the ambient

operating temperature and humidity.

• Do not use or store the product in the following locations:

• Locations subject to sudden or extreme changes in temperature.

• Locations subject to oil.

• Locations where high humidity may result in condensation.

• Locations prone to icing.

• Locations with excessive vibration or shock.

• Locations subject to exposure chemicals.

• Locations subject to water.

• Locations subject to bugs and small animals

• Do not use this Counter in dusty environments, in locations where

corrosive gasses are present, or in locations subject to direct

sunlight.

• Install the Counter well away from any sources of static electricity,

such as pipes transporting molding materials, powders, or liquids.

• Internal elements may be destroyed if a voltage outside the rated

voltage range is applied.

• Be sure that polarity is correct when wiring the terminals.

• 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

terminal.

• Up to two wires of the same size and type can be inserted into a

single terminals.

• Use the specified wires for wiring.

Applicable Wires: AWG 18 to AWG 22, solid or twisted, copper

(Wire material: 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 other contact so that the rated power supply

voltage will be reached within 0.1 seconds. If the power supply

voltage is not reached quickly enough, the Counter may

malfunction or outputs may be unstable.

• 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.

• 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.

• 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. (when using as a tachometer)

• If the set value and present value are both 0, the output will turn

ON for the default setting. The output will turn OFF during a reset

operation. (when using as a counter)

• 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.

• Do not use organic solvents (such as paint thinners or benzine),

strong alkali, or strong acids as they will damage the external

finish.

• Confirm that indications are working normally, including the

backlight LED, 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.

• The waterproof packing may deteriorate, shrink, or harden

depending on the application environment. Periodic inspection and

replacement are required.
