Safety Precautions for All H7CX Series (Common)

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.

H7CX 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.

• The panel surface of the H7CX-A/-R is water-resistant (conforming

to NEMA4, IP66, UL Type 4X (Indoor Use Only). To protect the

internal circuits from water penetration through the space between

the H7CX and operating panel, waterproof packing is included.

Attach the Y92F-30 Adapter with sufficient pressure with the

reinforcing screws so that water does not penetrate the panel.

• 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 in the following locations:

• Locations subject to sudden or extreme changes in temperature.

• Locations where high humidity may result in condensation.

• Do not use the Counter outside of the rated ranges for vibration,

shock, water exposure, and oil exposure.

• 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

• 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 H7CX

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 H7CX 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.

• 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 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. 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.

CAUTION

Precautions for Safe Use
