Digital output Warning. The output is closed during
24 VDC normal operation. If a warning occurs,
min. 10 k the connection is broken between D7
and D8.
The following warnings can occur:
- communication warning
- configuration warning
- too much water in oil
0 V
- stator insulation resistance below
warning limit.
