Alarm Output Circuit
The illustration shows an example of alarm output circuit. In this cir-
cuit, H5CN outputs an alarm when the time control by the other timer
is not completed within the set time of the former.

1. Since the H5CN Timer is capable of reading the input data at
any time during normal operation, 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 protective cover Y92A-48B.
2. When the set time is all zeroes (e.g., 000.0 s or 00 hrs 00 min),
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 state.
3. When changing the set time while power is being supplied, an
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 in the case when the
other three digits are all zero, since the improper setting of the
fourth switch to create four zeroes will cause a momentary
output.

, which is capable
of setting in 1/1000th of a second, since its digital display may
display an error of plus or minus 1/1000 s from the set value.
Battery Connection
Even if the unit is not provided with a backup battery, the count value
will be retained for a minimum of 10 min. If a backup battery is con-
nected, the count value will be retained for approx. 5 years. Replace
the backup battery as quickly as possible within 10 min.
