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
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 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 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 Tachometer or touch
internal components.

Precautions for Safe Use
1) 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.
2) 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.
3) 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.
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) Do not use the Tachometer outside of the rated ranges for vibration, shock, water exposure, and oil
exposure.
9) Internal elements may be destroyed if a voltage outside the rated voltage range is applied.
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
seconds. 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 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.
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 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.
22) The waterproof packing may deteriorate, shrink, or harden depending on the application environment.
Periodic inspection and replacement are required.

time
Note: The characters displayed in reverse video are the default settings.
1) 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.
2) Maintain voltage fluctuations in the power supply within the specified operating voltage range.
3) 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.
4) The input signal will not be accepted after 5 to 1005 ms has elapsed from when the power supply is
turned OFF.
5) 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.
6) The capacity of the external power supply is 100 mA at 12 V. When using a 24 VAC/12 to 24 VDC
power supply, reduce the load with the power supply voltage, as shown in the following diagram
(DC power supplies only).
7) If the prescale value setting is incorrect, a counting error will occur. Check that the settings are
correct before using this function.
8) 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.
9) 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).
10) EEPROM is used as memory when the power is interrupted. The write life of the EEPROM is
100,000 writes. The EEPROM is written when the power is turned OFF or when switching from
function setting mode to run mode.
11) Dispose of the product according to local ordinances as they apply.
• When conforming to EMC standards, refer to the information provided in this
Instruction Manual for cable selection and other conditions.
