1.Description
This module measures the operating hours of a device. At the same time, the operating hours are compared to a setpoint value. If the setpoint is exceeded, Output 3 sends a one. The remaining value (setpoint value minus operating hours) is output via Output 2.

| 1 | E1 Signal | 0 | Signal for monitoring - Counter starts if the value does not equal zero. |
| 2 | E2 MI (sec.) | 0 | Measuring interval in seconds - The value of the input is checked at these time intervals. If the value is not equal to zero, the elapsed operating time meter is increased by the measuring interval. |
| 3 | E3 Reset | 0 | Reset - A value not equal to zero sets the elapsed operating time meter to zero. Output 1 and Output 3 send a zero here. Output 2 sends the remaining value (then corresponds to the setpoint value). |
