CHAPTER 6 TROUBLESHOOTING
This section describes many common symptoms, with suggestions as to
what to do. If the issue persists, please contact your local Pulsar distributor.
SYMPTOM
WHAT TO DO
Display blank, transducer not firing. Check power supply, voltage selector
switch and fuse.
Displays “No Xducer”
Check wiring to transducer.
Displays “Xducer Flt”
There is a fault with the transducer wiring,
so check wiring to transducer.
Displays ‘Failed Safe’
The transducer has not been able to lock
on to a target. Check transducer wiring,
check P900 status. Check to see if
transducer is ‘clicking’, check for any
obstructions in the application.
Incorrect reading being displayed
for current level.
Measure actual distance from transducer
head to surface of material. Enter Program
Mode and directly access P21 (Set
Distance) type in the measured distance,
ENTER, ENTER again when prompted, wait
until SET displayed and return to Run
Mode, display should now update to
correct reading.
Material level is consistently
incorrect by the same amount.
Check empty level, (P105) display offset,
(P802) and measurement offset (P851).
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.
