Dr. Livingstone, I Presume WELDWISE 2400 - Manual (Page 135)

PROBLEM POSSIBLE CAUSE OR
SYMPTOM
POSSIBLE FIX
The sensor was not zeroed (displacement
only). Zero the displacement sensor. If the sensor will not zero, the
sensor, sensor cable or weld monitor may be malfunctioning.
Sensor failure. A reading of +/-32767 indicates that the input channel is
saturated and reading its maximum value. There may be a
problem with the sensor, sensor cable, or weld monitor.
Disconnect the sensor from the sensor cable. If the A/D reading
changes to a value of less than 100, the sensor may be
malfunctioning. Repair or replace the sensor. If the A/D reading
remains at maximum value then the sensor may be OK and the
sensor cable or weld monitor may be malfunctioning. Refer to
Section 6, Possible Sensor Cable Failure.
PEGGED A/D READING:
The Input Monitor
indicates a displacement
channel A/D reading of +/-
32767. This value never
changes; the other sensor
channels appear to be
working and the A/D values
for these channels are
changing/updating.
Sensor cable failure. Disconnect the sensor from the cable, if still pegged.
Disconnect cable from the weld monitor. If the A/D reading
changes to a value within +/- 100 from 0, the sensor cable
should be repaired or replaced. If the A/D reading remains at
maximum value, refer to Section 8, Trouble With Hardware.
Sensor failure. A static reading may indicate a problem with the sensor, sensor
cable, or weld monitor. Disconnect the sensor from the sensor
cable. If the A/D reading changes to a value of less than 100,
the sensor may be malfunctioning. Repair or replace the sensor.
If the A/D reading remains at the same value or does not change
to a value of less than 100, the sensor may be OK and the
sensor cable or weld monitor may be malfunctioning. Refer to
Section 6, Possible Sensor Cable Failure. FROZEN A/D READING
(DISPLACEMENT
ONLY): The Input
Monitor indicates a
constant (static) A/D
reading for the displacement
sensor. This value never
changes; the other sensor
channels appear to be
working and the A/D values
for these channels are
changing/updating.
Sensor cable failure. Disconnect the sensor from the cable, if value remains the
same. Disconnect cable from the weld monitor. If the A/D
reading changes to a value within +/- 100 from 0, the sensor
cable should be repaired or replaced. If the A/D reading
remains at maximum value, refer to Section 8, Trouble With
Hardware.
