Data Function
All alarms trip the alarm relay. The
Max. 250 VAC
alarm relay is closed during normal
operation.
In case of alarm or if the IO 111 is not
connected to the power supply, the
Max. 250 VAC
relay opens and breaks the connection
between T1 and T2.
1) 0 V
Analog output 1 has two functions set
2) 0 V
via DIP switch 7, see 6.5.
1. 4-20 mA for content of water in oil.
1) 15 VDC
2) 24 VDC,
2. Pulse output for content of water in
max. 100 mA
1) 0 V Analog output 2 has two indications set
2) 0 V via DIP switch 6, see 6.5.
1. 4-20 mA for stator winding
1) 15 VDC
2) 24 VDC,
rated 1 mA
2. Pt1000 emulator for stator winding
Feedback from motor contactor whether
0 V
the pump is running or not.
The input must be short-circuited when
the pump is running. The signal is used
by the IO 111 for filtering of measuring
Digital input
signals and for analysis during fault
indication.

For resetting of alarms, see 8.2.
The input must be short-circuited when
alarms are reset.
