6.5 Description of indicator lights
Pos. Symbol Description
6
Moisture
Red indicator light flashing for alarm in case of moisture in the motor.
7
Insulation resistance
Stator insulation resistance is indicated by a green, yellow or red light.
Green indicator light is on when the insulation resistance is correct, i.e. above the
warning level set on the potentiometer.
Yellow indicator light is permanently on when the warning limit has been reached,
see 4.1 Potentiometer.
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.
8
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).
16
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.
