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.
