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 operating hours counter 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 triggered. The actual value is then set to zero.
