232 Failure Causes and Solutions
15.8 Failure Causes and Solutions
When the controller does a circuit test, it will stop the system and alert you if failures were
detected during the test. The controller shows a window of possible causes and solutions
data. Refer to Figure 15-44. This window can also be opened when you touch the Display
Failure Data button on the System Setup screen (Heats Setup tab, Monitoring tab).
NOTE: Zones that are OFF will not be shown in the list.
No Connection, T/C Thermocouple circuit is broken.
Bad thermocouple.
Card is not seated.
Card is not calibrated.
Card is nonfunctional.
Zone far beyond 1100 °F or 600 °C.
Short the thermocouple input and it
should show an ambient
temperature on the operator
interface. If it does, the problem is
possibly a wiring issue. Inspect the
cables and mold for a bad
connection or broken thermocouple.
If the shorted thermocouple input
does not show an ambient
temperature, the problem is possibly
a loss of calibration or a
nonfunctional card. Recalibrate the
zone and if this does not work,
replace the card.
Temperature
Shows 0 °C (32 °F)
No communication with the card. Refer to the Read Time Out error
solution.
No Screen Bad touch monitor or computer.
Missing phase.
Do a check of the supply to the
controller to make sure there is not a
missing phase.
Replace the touch monitor with a
known good unit to see if the image
is restored. If so, replace the bad
touch monitor.
Replace the computer with a known
good unit to see if the image is
restored. If so, replace the bad
computer.
