Chapter 7 Troubleshooting
This section describes many common symptoms, with suggestions as to what to
do.
Display blank, transducer not
firing.
Check power supply, voltage selector
switch and fuse.
There is a fault with the transducer
wiring, so check wiring to transducer.
Incorrect reading being
displayed for current level on a
dB transducer.
Check the trace screen for the relevant
transducer. If there is an obstruction in
front of the true echo then enter
Program Mode and directly access P21
(Set Distance) for xdr1 or P1021 for
xdr2. Type in the distance of the true
echo and press ENTER. Press ENTER
again when prompted, wait until
‘Operation successful’ is displayed
and return to Run Mode, the 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.
Main display shows “Wiper
Fault”
There is a fault with the wiper. Check
transducer wiring (incl. motor
terminal). Use the hotkey (F5) to
initiate a manual wiper sweep. If the
message is still present then there is a
problem with the wiper or motor.
Remove the transducer from the
application, remove any fouling and
attempt a manual sweep once more. If
there is still a fault, consult Pulsar.
