Limit value for service counter
(when select. “Number” in increm. of 1000)
0 = Service counter switched off
The service counter can be used to monitor
a binary signal in respect to number
(switch-on edge) or time (ON state).
The service counter is started when
entering a value > 0. When the limit value is
exceeded, a signal is generated which can
be put out to a binary output.
The signal can only be acknowledged by
resetting the limit value to zero (service
counter switched off).
The counter value is saved every hour in
the EEPROM; the counter value saved last
is used to continue counting after a power
failure.
Special features on the device when
selecting "Number" (operation and display
only in the User level):
- Value range: 0…9999
(1 corresponds to 1000)
- Counter reading is displayed in Thousand
(1 corresponds to 1000); when the
counter value is below 1000, the display
shows 0.
- Simultaneously press the + keys:
The complete counter value is displayed on
both displays for approx. 3 s.
Example: Counter value 1234567;
upper display = 1234, lower display = 567
