6.8 ATEX/IECEx protection
ATEX/IECEx protection can be activated/deactivated by means of DIP switch 10.
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.
8. Indication
On the front the IO 111 has ten indicator lights for
sensor status. Figure 9 shows the location of lights
on the IO 111, and the table describes their
indication.
