This section describes many common symptoms, with suggestions as to
what to do.

Symptom

What to Do

“No Sensor” message displayed.

Check power supply. Check
wiring to FlowPulse sensor.

“P102 Fail” message is displayed

Check that the correct Device
Address (Modbus ID) for the
FlowPulse has been entered into
P142 of the Flow Monitor.

Current velocity reads zero but you
know there is flow movement.

Ensure FlowPulse sensor is
mounted correctly and in
accordance with chapter 2.

LED’s change colour at relevant
relay switch points but relays do not
change state.

Check supply to unit and ensure
voltage selector set to correct
position.
