Output Counter
Safety and Reliability
Isolated Power Supply and Input Circuits
Power supply circuit and input circuits are isolated inside the Counter.
Previous non-isolated counters had wiring restrictions and could be
damaged if wired incorrectly. The H7CZ removes these worries.
The output counter counts the number of times the output turns ON
(alarms can be displayed and the count can be monitored in
increments of 1,000 operations). This counter is useful in managing
the service life of the Counter or the load.
Other Features
Waterproof, Dust-proof Structure (UL508 Type
4X and IP66)
Worry-free application is possible in locations subject to water.
Note: When the Y92S-29 Waterproof Packing is used.
Key Protection
Select from any of seven protection patterns. Use the best one for the
application.

Protecting the Counter in Environments Subject to Oil
The H7CZ's panel surface is water-resistive (conforming to IP@6,
UL Type 4X) and so even if drops of water penetrate the gaps
between the keys, there will be no adverse effect on internal circuits.
If, however, there is a possibility of oil being present on the
operator's hands, use the Soft Cover. The Soft Cover ensures
protection equivalent to IP54F against oil. Do not, however, use the
H7CZ in locations where it would come in direct contact with oil.
Order this Waterproof Packing
separately if it is required.
The Waterproof Packing can be used
to achieve IP66 protection.
The Waterproof Packing will deteriorate, harden, and shrink
depending on the application environment. To ensure maintaining the
IP@6, UL Type 4X waterproof level, periodically replace the
Waterproof Packing. The periodic replacement period will depend on
the application environment. You must confirm the proper
replacement period. Use 1 year or less as a guideline. If the
Waterproof Packing is not replaced periodically, the waterproof level
will not be maintained. It is not necessary to mount the Waterproof
Packing if waterproof construction is not required.

Explanation of Functions
Set Value Upper Limit (sl-h)
Input Mode (cntm)
Set increment mode (UP) or decrement mode (DOWN) as the input
mode.
Output Mode (outm)
Set the way that control output for the present value is output. The
possible settings are N, F, C, R, K-1, P, Q, and A.
One-shot Output Time (otim)
Set the one-shot output time (0.01 to 99.99 s) for control output.
One-shot output can be used only when C, R, K-1, P, Q, or A is
selected as the output mode.
Counting Speed (cnts)
Set the maximum counting speed (30 Hz/5 kHz) for count inputs.
Reset Input Signal Width (iflt)
Set the reset input signal width (20 ms/1 ms) for reset inputs.
If contacts are used for the input signal, set the input signal width to
20 ms. Processing to eliminate chattering is performed for this setting.
Decimal Point Position (dp)
Decide the decimal point position for the present value.
Prescale Value (pscl)
Pulses input to the counter are converted according to the specified
prescale value.
(Setting range: 0.001 to 99.999 for 6-digit models.)
Example: To display the feed distance for systems that output 25
pulses for a feed length of 0.5 m in the form @@.@@ m:
1. Set the decimal point position to 2 decimal places.
2. Set the prescale value to 0.02 (0.5 ÷ 25).
0.5 m
25 pulses
Encoder
• Observe the following points when setting a prescale value.
Set the set value to a value less than {Maximum countable value
− Prescale value}.
Example: If the prescale value is 1.25 and the counting range is
0.000 to 999.999, set the set value to a value less than 998.749
(= 999.999 − 1.25).
If the set value is set to a value greater than this, output will not turn
ON.
• Output will turn ON, however, if a present value overflow occurs
(FFFFFF).
Note: If the prescale value setting is incorrect, a counting error will
occur. Check that the settings are correct before using this
function.
12
Set the upper limit for the set value when it is set in run mode.
The setting can be made from 1 to 999999 for 6-digit models.
Key Protect Level (kypt)
Set the key protect level.
Refer to Key Protect Level on page 16.
Output ON Count Alarm Set Value (on-a)

This includes times when the life of the EEPROM has expired.
The normal display and e3 will appear alternately.
When the Reset Key is pressed, e3 will not be displayed even if the alarm set value is exceeded.
(Monitoring is possible, however, because the counter will continue without the output ON count being cleared.)

Safety Precautions for All H7CZ Series (Common)
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 Counter 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)
• 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.
• Approximately 14 V is output from the input terminals. Use a
sensor that contains a diode.
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.
Sensor
Diode
0V
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.
Precautions for Safe Use
• The panel surface of the H7CZ 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 H7CZ 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.
Input
• 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 H7CZ
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 H7CZ 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.
• 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 LCD.
The indicator, 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.
0.5 to 1 mm
It is recommended that the
space between the screw
head and the Adapter be
0.5 to 1 mm.
• 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.

H7CZ
Precautions for Correct Use
Conformance to EN/IEC Standards
• 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.
• Maintain voltage fluctuations in the power supply within the
specified operating voltage range.
• When turning the power ON and OFF, input signal reception is
possible, unstable, or impossible as shown in the diagram below.
• 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.

• 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.
• 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).
• EEPROM is used as backup memory when the power is
interrupted. The write life of the EEPROM is 100,000 writes. The
EEPROM is written at the following times:
• When the power supply is turned OFF
• When switching from Configuration Selection Mode or Function
Setting Mode to Run Mode
• Dispose of the product according to local ordinances as they apply.
