H7CC-R@
57
Replacement Time Notification Function
The counter includes parts such as electrolytic capacitors and relays
that deteriorate with time or with repeated operations.
The H7CC is equipped with a function for notifying the replacement
time by the cumulative run time and ON count of the relay contact.
When either one of the deterioration of the electrolytic capacitors due
to the cumulative run time or the deterioration 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 (replacement time) error can be displayed on the Timer.
The extent of deterioration of electrolytic capacitors varies depending
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 are changing the actual
usage conditions, enter the ambient temperature, output load, and
utilization rate in the H7CC replacement time calculation tool
available on the OMRON website to calculate the appropriate
cumulative run time when the deterioration of electrolytic capacitors is
expected.
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 (replacement 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 memory has expired.
*2. Occurs when the measurement value reaches 999,999.
*3. Display flashes (1-second cycles).
*4. The normal display and Rplc will appear alternately.
When hold operation is performed, Rplc will not be displayed even if the alarm set value is exceeded. (Monitoring is possible, however,
because the counter will continue without the cumulative run 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 hold 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.
