The Easiest Operation
Operation is simplified by the Up/Down
Keys for each digit on 4-digit.
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.
*1. H5CZ with 100 to 240-VAC specifications.
Set Value Limit
You can set an upper limit for the set value to prevent unexpected
operation of output devices caused by setting mistakes.
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.
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.
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.
New Modes
Modes, such as a stopwatch mode (Mode S), have been added.
Select any of 15 modes.
Refer to Safety Precautions on page 29.

Protecting the Timer in Environments Subject to Oil
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.
Note:
Depending on the operating environment, the condition of
resin products may deteriorate, and may shrink or become
harder. Therefore, it is recommended that resin products are
replaced regularly.
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.

Explanation of Functions
Operating Procedures for Timer Function
Time Range (timr)
Set the range to be timed in the range 0.001 s to 9,999 h.
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.
Instantaneous/Time-limit (otmd)
Set the contact output to time-limit SPDT + instantaneous SPDT or
time-limit SPDT operation.
Set Value Upper Limit (sl-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.
Output ON Count Alarm Set Value (on-a)
Set the alarm value for the output ON count.
The limit can be set to between 0 x 1000 (0 times) and 9999 x 1000
(9,999,000 times). Only the underlined values are set. The alarm will
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)
Set the ON count alarm values for the outputs 1 and 2.
The limit can be set to between 0 x 1000 (0 times) and 9999 x 1000
(9,999,000 times). Only the underlined values are set. The alarm will
be disabled if 0 is set.
If the total ON count of instantaneous output 1 or 2 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.
Output ON Count Monitor Value (on-c)
The monitor value is only displayed. It cannot be set.
The output ON count will be 1,000 times the displayed value.
ON Count Monitor Values for Outputs 1 and 2 (OUT1 and
OUT2) (on1c and on2c)
The monitor value for output 1 or 2 is only displayed. It cannot be set.
The output ON count will be 1,000 times the displayed value.

Operation in Run Mode
Operating Procedures for Timer Function
Present Value and Set Value
These items are displayed when the power is turned ON. The present
value is displayed in the main display and the set value is displayed
in the sub-display.
The values displayed will be determined by the settings made for the
time range and the timer mode in function setting mode.
Present Value and ON Duty Ratio (Output Mode = Z)
The present value is displayed in the main display and the ON duty
ratio is displayed in the sub-display. Set the ON duty ratio used in ON/
OFF-duty-adjustable flicker mode (Z) as a percentage.
The output accuracy will vary with the time range, even if the ON duty
ratio setting is the same. Therefore, if fine output time adjustment is
required, it is recommended that the time range for the cycle time is
set as small as possible.
Examples: 1. When Time Range = - - - - s (9999 s)
Rounded off to the nearest integer (because of the
time range setting) →ON time = 6 s
2. When Time Range = - -. - - s (99.99 s)
Rounded off to 2 decimal places (because of the time
range setting) →ON time = 6.20 s
If a cycle time is set, cyclic control can be performed in ON/OFF-duty-
adjustable flicker mode simply by changing the ON duty ratio.
Present Value and Cycle Time (Output Mode = Z)
The present value is displayed in the main display and the cycle time
is displayed in the sub-display. Set the cycle time.
