■ Precautions for Correct Use
Battery Connections when Using
Backup Power for Memory Protection
Always connect a battery when using models with backup power for
memory protection. Any 3-V battery can be used, but the backup
time will depend on the capacity of the battery. When using the Unit
for the first time after purchase, apply power and reset the Unit once
before using it. When power is turned ON for the first time, outputs
may be produced at the same time, so do not connect the output
terminals.
If a power interruption continues for 10 minutes or more when a
battery is not connected, the count value and displays may be
meaningless, and outputs may be produced unpredictably even if the
power supply recovers. If this happens, apply power to the reset input
once before using the Unit further. (The Unit can be used after
turning ON the reset input, regardless of whether a battery is
connected or not.)
Regular battery replacement (every 4 to 5 years) is recommended.
The life of the battery depends on the frequency of power failures.
Connection Methods
The Y92S-20 Backup Battery used for the H5CN-X@NM is a lithium
battery (non-explosion-proof). Do not short-circuit the positive and
negative sides of the battery, recharge or disassemble the battery,
deform the battery under pressure, or dispose of the battery in fire.
Doing so may occasionally cause the battery to burst, ignite, or leak.
Use only the specified battery. Otherwise, the battery may leak or
burst, occasionally causing damage to the equipment or minor injury.

1. The H5CN Timer is capable of reading the input data at any time
2. When the set time is all zeroes (e.g., 000.0 s or 00 h 00 min),
3. When changing the set time while power is being supplied, an

If the set value is changed to a value higher than the currently
displayed present value, the timer will time out for the new set
value.
When the set value changes, the difference between the new set
value and old set value will be added or subtracted from the
present value.

during normal operation. This means that the set time can be
changed during power application. This feature sets back the
output from the timer by temporarily setting the longer time or
quickens the output by setting the shorter time. During normal
operation, the set time may be accidentally changed by touching
a thumbwheel switch. To prevent this possibility, use the optional
Y92A-48@ Protective Cover.
there will be a momentary control output upon power application,
which can be used to check normal output. When changing the
set time during normal operation, pay special attention not to alter
the set value to this all zeroes.
inadequate push of the thumbwheel switches will display two
numbers in one digital display window, causing the operating time
to drift widely. Therefore, press the thumb-wheel switches surely.
Take particular care when the other three digits are all zeroes,
because the improper setting of the fourth switch to create four
zeroes will cause an instantaneous output.
