D1
Terminal for
alarm in case of
too high stator
temperature
Digital output
24 VDC
Min. impedance
10 kΩ
Max. rated
current 2.4 mA
Alarm for temperature too high 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
temperature
0 V
D3
Terminal for
alarm in case of
moisture in the
pump
Digital output
24 VDC
Min. impedance
10 kΩ
Max. rated
current 2.4 mA
Alarm for 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
pump
0 V
D5
Output for alarm
in case of
insulation fault
Digital output
24 VDC
Min. impedance
10 kΩ
Max. rated
current 2.4 mA
Alarm for 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. impedance
10 kΩ
Max. rated
current 2.4 mA 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 the oil
– stator insulation resistance
below warning limit.
