Condition Evaluate
The bottom two
LEDs are on and
occasionally they go
out and the top two
flash and then return
to the bottom two
LEDs on (or vice-
versa). (REMOTE).
Check for large noise spikes on the data line.
Insure that the unit’s ground potential is the same as the Master’s.
Insure that the data line is not chaffed and making contact with
other electrical wires.
The points calibrated
seemed to have
changed.
Self test the unit to check for any malfunctions.
Check the pressure transducer for problems.
Recalibrate the unit and take a voltage reading from the transducer
(pin 7 on the unit’s connector) at each calibration point. When the
calibration points again look wrong check the voltages at those
points and determine if they are the same as the voltage reading
taken during calibration.
Unit will not dim
display.
Insure the Dim input voltage on Pin 3 is at least 9V. Recalibrate dim
setting (RLLR LLLR). If unit does not dim LEDs while in dim
calibrate mode, replace unit.
The two top amber
LEDs are flashing
together.
A calibration was started on the unit but not completed correctly.
Set the unit to a REMOTE unit (LRLR LRLR) or calibrate it as a
MASTER (follow calibration steps exactly).
Top LED is the only
LED illuminated.
The unit has had a memory error.
Attempt to set the unit back to REMOTE or MASTER as required.
