CAUTION
Electric shock
Minor or moderate personal injury
‐
The motor-protective circuit breaker
of the pump controller must include
a circuit that automatically
disconnects the power supply in
case the protective circuit for the
pump is opened.

6.6 IO 113
IO 113 provides an interface between a Grundfos
wastewater pump equipped with sensors and the
pump controller(s). The most important sensor
status information is indicated on the front panel.
One pump can be connected to one IO 113
module.
Together with the sensors, the IO 113 provides a
galvanic isolation between the motor voltage in
the pump and the connected controller(s).
As standard, IO 113 is capable of the following:
• Protect the pump against overheating.
• Monitor the status of the following items:
- motor winding temperature
- leakage (WIO)
- moisture in the pump.
• Measure the stator insulation resistance.
• Stop the pump in case of alarm.
• Remotely monitor the pump through RS-485
communication (Modbus or GENIbus).
• Control the pump by frequency converter.
