MultiSmart Installation & Operation Manual

32 Troubleshooting

Common problems and their resolution:

32.1 There is no level displayed on my unit

First check the I/O module is reading the input(s) correctly. From the main operator screen, press Info, then
I/O Information, then choose a board (typically Top Board), then select the relevant input type as described
below.
32.1.1 Analog level device
If you are using a 4-20mA level device, choose Analog Input. If the input is at 0mA then one of the following
maybe the cause:
the level device is not properly connected
•
the level device is not properly configured
•
there is a problem with the MultiSmart I/O card. Problems with I/O cards can often be seen in the
•
system log in Info, System Log.
If the input is reading between 4-20mA, the pump control module is not configured to use this level device.
From the main operator screen, press Settings, I/O faults & level, Level devices. The primary level device
will probably be showing a different analog input or a MultiTrode probe – i.e. it has not been correctly
configured. It's possible to go back through the Setup Wizard at any time to generate a completely new
configuration, however it is easier to configure the level device using the Level Devices screen, (see Section
14.8).
32.1.2 Probe
If you are using a MultiTrode conductive probe, choose Digital Inputs. Check that some of the sensors are
covered (the value should be showing as ON). If none of the probe sensors are reading ON, then one of the
following is the problem:
You have not connected the probe
•
The probe is not covered with conductive liquid
•
There is no ground (earth) return for the probe
•
There is a problem with the MultiSmart I/O card. Problems with I/O cards can often be seen in the
•
system log in Info, System Log.
If the DINs are showing an ON status, then the pump control module is not configured correctly. From the
main operator screen, press Settings, I/O faults & level, Level Devices. The primary level device needs to
be changed to Probe – or the correct sensors need to be assigned. For example, when the probe is selected
as the level device, by default, DIN 2-11 are configured for the 10 sensors. If the probe has been wired
differently, either rewire the probe to the default connections or edit the sensor configuration (using the Level
Devices screen - see Section 14.8). It is also possible to go back through the Setup Wizard however this
will create a completely new configuration.

32.2 Every time the pump starts I see a Contactor Auxiliary fault

The default wiring diagram for the pump station manager usually includes feedback from the contactor to
indicate that the pump has started. If you have followed the wiring diagram correctly then the MultiSmart unit
is indicating one of the following
That the contactor has failed (check contactor)
•
The pump output relay is not wired to the contactor (check wiring)
•
The output relay has been reconfigured (see Section 14)
•
The output relay has a problem (check the System Log in the Info screen)
•
If you don't have a contactor auxiliary output, see Section 9.3 for how to unassign this fault.
