7. Start-up

When the IO 111 has been set up as described in
5. Installation, start-up must be carried out by an
authorised person.
1. Switch on the power supply to the IO 111 before
starting the pump.
2. The IO 111 now carries out a self-test. All
indicator lights on the front panel will be on for a
few seconds. If the IO 111 does not detect any
fault, all indicator lights will go out except those
for water in oil and stator insulation resistance. If
a fault is detected, the indicator light for the
actual fault will illuminate.
3. Check that there are no warnings or alarms
before switching on the pump.
