Grundfos IO 111 User Manual

The IO 111 operates with two categories of fault:
1. Alarm. The pump stops. The fault is a primary
functionality (e.g. too high motor temperature).
The relay opens and breaks the connection
between T1 and T2 (pos. 1) in case of alarm or if
the IO 111 is not connected to the power supply.
Alarm is indicated by the indicator lights on the
front of the IO 111 and via the three digital
outputs (pos. 16).
2. Warning. The pump does not stop. The fault is a
secondary functionality (e.g. too much water in
the oil).
Warning is indicated by the indicator lights on the
front of the IO 111. The warning status can be
read via the digital outputs D7 and D8 (pos. 16).
