warning level set on the potentiometer.
Yellow
indicator light is permanently on when the
warning
limit has been reached,
see
.
Red
indicator light flashing when the
alarm
limit has been reached, i.e. below 1 MΩ.
Note:
The indicator lights are only active if the conductor for contactor status is
connected (K1, K2 ). This measurement is only correct when the motor is stopped.

Leakage
For wastewater pumps:
Green
indicator light permanently on indicates leakage below 5 %.
Green
indicator light flashing indicates leakage between 5 and 10 %.
Yellow
indicator light permanently on indicates leakage between 10 and 15 %.
Yellow
indicator light flashing indicates that the input signal is out of range.
Red
indicator light flashing indicates leakage between 15 and 20 %.
Red
indicator light permanently on indicates leakage above 20 %, or oil chamber is
empty.
For SE/SL 9-30 kW:
The
indicator light is off when the WIO/WIA sensor is disabled.
Green
indicator light permanently on indicates that the pump works correctly.
Red
indicator light flashing indicates alarm.
9
Vibrations
Yellow
indicator light permanently on when vibrations are in the warning range
(exceeds alarm range).
13
Temperature
Red
indicator light flashing for alarm when temperature is above the limit.
If ATEX/IEC Ex protection is activated (DIP switch 10), this indicator light can also
indicate the following:
•
bearing temperature too high.
•
missing signal from bearing sensor (with SM 113).
15
Motor running
Green
indicator light is permanently on when motor is running.
Note:
The indicator light is only active if the conductor for contactor status is
connected (K1, K2).

Service
Yellow
indicator light permanently on when there is a communication problem
between IO 113 and SM 113.
Yellow
indicator light flashing when there is a warning. Immediate service is
needed.
