The Y92S-20 Backup Battery (sold separately) provides power backup for memory protection during power failures for approximately
5 years (at 20°C). Always connect a battery to the H5CN-X@NM. For details on connection methods, refer to page 5.
3.
The H5CN-X@NM does not support power resetting.

These values represent the total accuracy of the timer including the repeat accuracy, setting error, and variation due to voltage and tem-
perature changes. Note that they also comprise errors due to the rise time of the power source and the operating times of the internal
and output circuits.

Note: 1.
If the reset input is short-circuited (be-
tween terminals
A
and
C),
immediately
the count circuit is reset to 0 and the con-
trol output relay is reset to OFF. The tim-
er starts as soon as the reset input is
opened (between terminals
A
and
C).
2.
If the gate input is short-circuited (be-
tween terminals
A
and
D),
the count cir-
cuit stops immediately. The timer then
restarts as soon as the gate input is
opened (between terminals
A
and
D).
