The operating hours counter counts in the range from 0 hours to way over

4.9.2 Accuracy of the operating hours counter
The operating hours counter counts in seconds. When the device is switched
off, up to 999 ms can be lost.
4.9.3 Function of the operating hours counter function relay
When the coil of the O operating hours counter is set to 1, the counter
increments its actual value by 1 (basic pulse: 1 second).
If the actual value of the hours-run counter reaches the setpoint value of S,
the contact O… switches for as long as the actual value is greater than or
equal to the setpoint value.
The actual value is kept stored in the device until the Reset coil RO… is
triggered. The actual value is then set to zero.
