8.7 IO 111
The IO 111 forms interface between a Grundfos sewage or
wastewater pump with analogue and digital sensors and the
pump controller. The most important sensor data are indicated on
the front panel.
One pump can be connected to an IO 111.
Together with the sensors, the IO 111 forms a galvanic separation
between the motor voltage in the pump and the controller
connected.
IO 111 can distinguish between two categories of fault:
•
Alarm: The pump stops. The fault is serious, such as too high
motor temperature.
•
Warning: The pump does not stop. The fault is not serious,
such as too much water in the oil.

8.8 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).
IO 113 can do the following as standard:
•
Protect the pump against overheating.
•
Monitor the status of these items:
– motor winding temperature
– leakage (WIO/WIA)
– moisture in pump.
•
Measure the stator insulation resistance.
•
Stop the pump in case of alarm.
•
Remotely monitor the pump via RS-485 communication
(Modbus or GENIbus).
•
Control the pump via a frequency converter.
Warning
The IO 113 must not be used for purposes other than
those specified above.
