Basic Features
Set Value Limit
Better Readability
You can set an upper limit for the set value to prevent unexpected
operation of output devices caused by setting mistakes.
Character Height of 10 mm with a Wide Viewing Angle.
Easy to read from the top,
bottom, and sides.
10 mm (actual size)
Worry-free operation is
achieved with the H5CZ
by restricting the time
that can be set.
Clear
Confirmation
Output Counter
The output counter counts the number of times the output turns ON
(alarm display, count monitoring, count in increments of 1,000). This
counter is useful in managing the service life of the Timer or the load.
The Easiest Operation
Operation is simplified by the Up/Down
Keys for each digit on 4-digit.
Other Features
Models with Instantaneous Contact Output
Models with instantaneous contact outputs have been added for use
with self-holding circuits and as auxiliary relays. These models are
also convenient when replacing analog timers.
Safety and Reliability
Isolated Power Supply and Input Circuits *1
Power supply circuit and input circuits are isolated for safety and
reliability.
Previous non-isolated timers had wiring restrictions and could be damaged if
wired incorrectly. The H5CZ removes these worries.

Protecting the Timer in Environments Subject to Oil
The H5CZ's panel surface is water-resistive (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 IP54
against oil. Do not, however, use the H5CZ 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.

Time Range (timr)
Set Value Upper Limit (sl-h)
Set the range to be timed in the range 0.001 s to 9,999 h.
Set the upper limit for the set value when it is set in Run Mode.
The limit can be set to between 1 and 9999.
This setting does not apply to the ON duty in Z mode.
Timer Mode (timm)
Set either the elapsed time (UP) or remaining time (DOWN) mode.
In UP mode, the elapsed time is displayed, and in DOWN mode, the
remaining time is displayed.
Output Mode (outm)
Set the output mode.
The possible settings are A, A-1, A-2, A-3, b, b-1, d, E, F, Z and S.
(For details on output mode operation, refer to “Timing Charts” on
page 16.)
Output Time (otim)
When using one-shot output, set the output time for one-shot output
(0.01 to 99.99 s).
One-shot output can be used only if the selected output mode is A,
A-1, A-2, A-3, b, b-1 or S.
If the output time is set to 0.00, hold is displayed, and the output is
held.
Input Signal Width (iflt)
Set the minimum signal input width (20 ms or 1 ms) for signal and
reset inputs.
The same setting is used for all external inputs (signal and 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.
Key Protect Level (kypt)
Set the key protect level.
Refer to “Key Protect Level” on page 28.

be disabled if 0 is set.
If the total ON count of the output exceeds the alarm set value, e3 will
be displayed on the Timer to indicate that the output ON count alarm
value was exceeded. Refer to “Self-diagnostic Function” on page
28 for information on the e3 display.
ON Count Alarm Set Values for Outputs 1 and 2 (OUT1
and OUT2) (on1a and on2a)

H5CZ
Safety Precautions for All H5CZ 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 Timer 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 Timer or touch internal components.
Precautions for Safe Use
• The panel surface of the H5CZ 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 H5CZ 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.
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 Timer 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 Timer at the specified temperature. If the Time has been
stored at a temperature of less than -10°C, allow the Time to stand
at room temperature for at least 3 hours before use.
• Mounting the Timer side-by-side may reduce the life expectancies
of internal components.
• Use the Timer 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 Timer outside of the rated ranges for vibration,
shock, water exposure, and oil exposure.
• Do not use this Timer in dusty environments, in locations where
corrosive gasses are present, or in locations subject to direct
sunlight.
• Install the Timer 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 Timer 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.
Sensor
Diode
0V
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 Timer 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 a timing operation, the output
will turn ON if the set value is changed as follows because of the
use of a constant read-in system:
Elapsed time (UP) mode: Present value ≥ Set value
Remaining time (DOWN) mode: Elapsed time ≥ Set value (The
present value is set to 0.)
When in the remaining time mode, the amount the set value is
changed is added to or subtracted from the present value.
Operation with a set value of 0 will vary with the output mode. Refer
to the timing charts on page 16.
• 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.
29
H5CZ
Precautions for Correct Use
• H5CZ models with a 24-VDC/12 to 24-VDC power supply use a
transformer-free power supply method in which the power supply
terminals are not isolated from the signal input terminals. If a nonisolating DC power supply is used, unwanted current paths may
occasionally burn or destroy internal components depending on
the wiring. Always check the wiring sufficiently before use.
• 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 Timer 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.
Power ON
supply OFF
200ms 0 to 50 ms
Input
Impossible
Unstable
5ms
Possible
0 to 500 ms
Unstable Impossible
• To allow for the startup time of peripheral devices (sensors, etc.),
the Timer starts timing operation between 200 to 250 ms after
power is turned ON. For this reason, in operations where timing
starts from power ON, the time display will actually start from 249
ms. If the set value is 249 ms or less, the time until output turns ON
will be a fixed value between 200 and 250. The present value
display will start from 250 ms. (Normal operation is possible for set
values of 250 ms or more.) In applications where a set value of 249
ms or less is required, use start timing with signal input.
• 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.
• 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 Timer 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 Timer/Twin Timer Selection Mode or
Function Setting Mode to Run Mode
• Dispose of the product according to local ordinances as they apply.
30
Conformance to EN/IEC Standards
• 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 the power supply and input
terminals. (No insulation is provided between the power supply and
input terminals for the H5CZ-L8D.)
Basic insulation is provided 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.
