INFORMATION
TIMING
As long as the input En is active the time is measured. The current counter value is output at AQ. The parameter U allows the unit of time to be specified. Parameter U relates only to the analogue output AQ and not to the user interface!
| Parameter value | Unit of time |
| U = 0 | Seconds |
| U = 1 | Minutes |
| U = 2 | Hours |
| U = 3 | Days |
At the output AQ the total operating time of the counter is displayed. At AQl the last start time is displayed and at AQr the time remaining to the next maintenance interval.
SERVICE INTERVAL
The maintenance interval is specified by the parameter MI. At the operating time of the specified maintenance interval Q is activated. A pulse at the input R puts the maintenance interval counter back to zero and the input RA resets the operating time counter completely.
USER INTERFACE
The operating time counter or maintenance counter can be used and edited in the user interface.

Examples:
Maintenance intervals of filters, run time monitoring of motors etc.
OVERVIEW
INPUT
| En | Enable | If En = 1, the counter is active |
| R | Reset | Resets maintenance interval (to Parameter MI) |
| RA | Total Reset | Resets all counters to 0 |
PARAMETER
| U | Unit for time | U = 0: Seconds U = 1: Minutes U = 2: Hours U = 3: Days |
| MI | Maintenance interval | Input format for the function blocks input in seconds. If MI = 0, output Q is without a function. |
OUTPUTS
| Q | State Maintenance interval | On, if maintenance interval has been exceeded |
| AQ | Total time | Total time of operating time counter |
| AQl | Last start time | Last start time |
| AQr | Time to maintenance | Time remaining to maintenance interval |
