Make sure that the effective volume of the pit does
not become so low that the number of starts per hour
exceeds the maximum permissible number. See
section 10. Technical data.
7.2.3 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 cover.
One pump can be connected to one IO 113. Together
with the sensors, 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 or WIA)
– moisture in the 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.

Do not use IO 113 for other purposes than
those mentioned in the installation and
operating instructions for IO 113.
