1
T1
Terminal for
alarm relay
Max. 250 VAC
All alarms trip the alarm relay. The
alarm relay is closed during normal
operation.
In case of alarm or if the IO 111 is not
connected to the power supply, the
relay opens and breaks the connection
between T1 and T2.
T2
Terminal for
alarm relay
Max. 250 VAC

G1
GND for analog
output 1
1) 0 V
2) 0 V
Analog output 1 has two functions set
via DIP switch 7, see
6.5
.
1. 4-20 mA for content of water in oil.
Load resistance: Max. 250
Ω
.
2. Pulse output for content of water in
oil and stator insulation resistance.
A1
Terminal for
analog output 1
1) 15 VDC
2) 24 VDC,
max. 100 mA
G2
GND for analog
output 2
1) 0 V
2) 0 V
Analog output 2 has two indications set
via DIP switch 6, see
6.5
.
1. 4-20 mA for stator winding
temperature.
Load resistance: Max. 250
Ω
.
There is no 4-20mA signal in PTC
installations.
2. Pt1000 emulator for stator winding
temperature.
A2
Terminal for
analog output 2
1) 15 VDC
2) 24 VDC,
rated 1 mA
K1
GND
connection
0 V
Feedback from motor contactor whether
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
signals and for analysis during fault
indication.
K2
Terminal for
conductor for
contactor status
Digital input
R1
GND
connection
0 V
For resetting of alarms, see
8.2
.
The input must be short-circuited when
alarms are reset.
