Commissioning steps:
Note
If the current carrying capacity of the digital output could be exceeded, an auxiliary contactor
may possibly be used (refer to the Equipment Manual for Booksize Power Units)!
1. Connect control contact of the line contactor to DI/DO 14.
2. Parameterize DI/DO 14 as output (p0728.14 = 1).
3. Interconnect (BI: p0744 = r0863.1) DI/DO 14 with "control contactor" signal (r0863.1).
4. Connect the feedback contact of the line contactor to DI 7.
5. Interconnect (BI: p0860 = r0723.7) p0860 with the inverted input signal (p0723.7).
6. Enter the monitoring time of the line contactor (p0861 = 100 ms).
