D1
Terminal for
alarm in case of
too high stator
temperature
Digital output
24 VDC
min. 10 k
Ω
Alarm in case of too high temperature in
the stator windings. The output is
closed during normal operation.
If an alarm occurs, the connection is
broken between D1 and D2.
D2
GND for alarm
in case of too
high stator tem-
perature
0 V
D3
Terminal for
alarm in case of
moisture in the
motor
Digital output
24 VDC
min. 10 k
Ω
Alarm in case of moisture in the motor
part of the pump. The output is closed
during normal operation. If an alarm
occurs, the connection is broken
between D3 and D4.
D4
GND for alarm
in case of
moisture in the
motor
0 V
D5
Output for alarm
in case of insu-
lation fault
Digital output
24 VDC
min. 10 k
Ω
Alarm in case of too low insulation
value between stator windings and
earth. The output is closed during
normal operation. If an alarm occurs,
the connection is broken between D5
and D6.
D6
GND for alarm
in case of
insulation fault
0 V
D7
Terminal for
warning
Digital output
24 VDC
min. 10 k
Ω
Warning. The output is closed during
normal operation. If a warning occurs,
the connection is broken between D7
and D8.
The following warnings can occur:
- communication warning
- configuration warning
- too much water in oil
- stator insulation resistance below
warning limit.
