General
The devices have four independent operating hours counters.
This operating hours counter enables you to record the operating hours of systems, machines and machine parts.
You can enter a setpoint within the valid value range 0...999999. This enables maintenance times to be detected and reported.
The counter state is also retained when de-energized.
A counter relay can be used both as a coil or as a contact (switch contact) in your circuit diagram.
Note: The actual value can only be cleared via the Reset coil!
Even operations such as the RUN -> STOP mode change, Voltage ON -> OFF, delete or modify program or delete new program do
not delete the actual value of the operating hours counter.
Function
If the counter coil
TO is set to 1, the counter increments its actual value every second by the value 1 (basic pulse: 1 second).
If the actual value reaches the setpoint of
S, the contact
O switches for as long as the actual value is greater than or equal to the setpoint.
The actual value is kept stored in the device until the Reset coil
RO is set to
1 The actual value is then set to zero.
Accuracy of the operating hours counter
As the operating hours counter counts in seconds, up to 999 ms can be lost if a device is switched off.
