H5CC

Replacement Time Notification Function
The Timer includes parts such as electrolytic capacitors and relays that deteriorate with time or with repeated operations.
The H5CC is equipped with a function for notifying the replacement time by the cumulative run time and ON count of the re
lay contact.
When either one of the deterioration of the electrolytic capacitors due to the cumulative run time or the deterior
ation of the relay contact due to the
output ON count reaches the replacement time, Rplc (REPLACE) can be displayed on the Timer. For details on RPLC display, refer to Self-
diagnosis Function on this page.
Cumulative Run Time Alarm Set Value (ot-a)
The cumulative run time can be set in a range from 0.0 to 99.9 years. The replacement time notification function is disabled if 0 is set.
10 years is set in the default settings.
If the cumulative run time reaches the alarm set value or above, an RPLC (r
eplacement time) error can be displayed on the Timer.
The extent of deterioration of electrolytic capacitors varies dependin
g on the capacitor temperature and usage period. According to the default
settings, the ambient temperature is 35°C, the output load is 50%, and the utilization rate is 100%. If you change the usage conditions to actual
ones, use H5CC replacement time calculation tool on the OMRON website.
Output ON Count Alarm Set Value (on-a, on1a, on2a)
Set the alarm value for the output ON count.
The limit can be set between
0×1000 (0 times) and 9999×1000 (9,999,000 times). Only the underlined values are set. The alarm will be disabled
if 0 is set.
100,000 times is set in the default settings.
If the total output ON count reaches the alarm set value or above,
an RPLC (r
eplacement time) error can be displayed on the Timer.
Self-diagnostic Function
The following displays will appear if an error occurs.
*1. This includes times when the life of the non-volatile memor
y has expired.
*2. This is displayed if the alarm value setting for either of the two outpu
ts is exceeded if a model with two outputs is used. The total ON count will
not be cleared by reset operation.
*3. The normal display and Rplc will appear
alternately.
When reset operation is performed, Rplc will not be displayed even if the alarm set value is exceed
ed.
(Monitoring is possible, however, because the counter will continue without the cumulative r
un time and output ON count being cleared.)
Rplc is displayed again if the power is turned OFF/ON after the Rplc display is cleared
during recovery by the reset operation. If you do not
want to display Rplc when the power is turned OFF/ON, either change the alarm set value to the present value or above, or change the alarm
set value to 0 to disable it.
