Timer Control with Power Start
The timer will start 160 to 250 ms after the H5CL is turned on due to
the startup time required for the sensor and any other peripheral de-
vices connected to the H5CL (refer to the timing chart on the pre-
vious page). As a result, the control output of the H5CL will turn ON
at a specific point in time within a range of 160 to 250 ms after the
H5CL is turned on for any set value that is 216 ms or less. The pres-
ent value will be displayed 216 ms after the H5CL is turned on. The
H5CL operates normally if the set value is 217 ms or more.
If a set value of 216 ms or less is needed, operate the H5CL using a
signal start.
When the H5CL is used with power start in F mode (i.e., accumula-
tive operation with output on hold), there will be a timer error
(approximately 100 ms each time the H5CL is turned on) due to the
characteristics of the internal circuitry.
Use the H5CL with signal start if timer accuracy is required.
Transistor Output
The transistor output of the H5CL is insulated from the internal cir-
cuitry by a photocoupler, so the transistor output can be used as
both NPN and PNP output.
The diode connected to the collector of the output transistor is used
to absorb inverted voltage that is generated when an inductive load
is connected to the H5CL.

Operating Environment
When using the Timer in an area with excess electronic noise, sepa-
rate the Timer, wiring, and the equipment which generates the input
signals as far as possible from the noise sources. It is also recom-
mended to shield the input signal wiring to prevent electronic inter-
ference.
Organic solvents (such as paint thinner), as well as very acidic or
basic solutions can damage the outer casing of the Timer.
Preset Value Change
When changing preset value during timing operation, output will
turn ON if preset value is changed as follows:
Display mode UP:
Present value
(
preset value
Display mode DOWN: Elapse time
(
preset value
(Present value = 0)
Note:
When in down mode, the changed amount of preset value
is added to or subtracted from the present value.
Reset with a Preset Value of 0
The output will go ON when the start signal is input. The output will
be OFF while the reset key is pressed or the reset input is ON.
Power Failure Backup
All data is stored in the EEPROM when there is power failure. The
EEPROM can be overwritten more than 200,000 times.

Flush Mounting
The H5CL’s panel surface is water-resistive (conforming to NEMA 4
(indoors) and IP66). In order to prevent the internal circuit from wa-
ter penetration through the space between the timer and operating
panel, attach a rubber packing (provided with the H5CL) between
the timer and operating panel and secure the rubber packing with
the Y92F-30 flush-mounting adaptor.
It is recommended that the space between
the screw head and the adaptor should be
0.5 to 1 mm.
0.5 to 1 mm
Other
In case of performing a dielectric strength test, etc., on the H5CL
mounted to a control panel, disconnect the H5CL from the connect-
ing circuit, or short-circuit all the terminals of the H5CL.
Otherwise the H5CL may be damaged.
Terminal 1 (power supply terminal) and terminal 6 (input common:
0 V for input) of DC model H5CL are internally connected to each
other.
