4-2 Troubleshooting
Alarms / Trouble Possible Causes Verifications and Actions
Alarm Conveyor 2 –
Speed Band Alarm
Speed Sensor defective Check the sensor position and compare to the pinion
teeth. Check the wiring.
AL2 too low Increase the value of the alarm band.
Bad calibration
Recalibrate the conveyor (Refer to the TC V3 Operations
Manual).
High Temperature
Alarm (AL1)
Bad PID loop tuning Perform an auto-tune procedure.
Thermocouple defective Check the thermocouple wiring and location. It should be
in contact with the vitro-ceramic glass.
Temperature Band
Alarm (AL2)
Bad PID loop tuning Perform an auto-tune procedure.
Thermocouple defective Check the thermocouple wiring and location. It should be
in contact with the vitro-ceramic glass.
alarm band Value on recipe too
small
Increase the value in the receipt.
Thermocouple Short
Cut Alarm
Thermocouple defective Check the thermocouple wiring and location. It should be
in contact with the vitro-ceramic glass.
Bad PID loop tuning Perform an auto-tune procedure.
zone Fuse or circuit breaker
down
Check the fuse or the circuit breaker.
Resistor broken Check the resistor.
Static Relay Check the relay.
Thermocouple Broken
Alarm
Thermocouple defective Change the thermocouple.
Defective wiring Check the wiring.
Security Bar Alarm
Security bar not in place Place the bar in the correct position.
Sensor bad adjust Adjust the sensor.
Reflector broken Replace the reflector.
Open Hood Alarm
Hood close sensor defective Check the position and the wiring of the magnetic
sensor.
Circuit breaker/fuse of the
electrical cylinder down
Check the circuit breaker/fuse.
Exhaust Alarm
Air flow Check the airflow and compare to the one specified.
Increase the exhaust air flow if necessary.
Flow pressure sensor defective Check the wiring of the sensor, the pipe connection, and
the adjustment screw.
PCB spacing length is
lower to PCB hole max
length
Recipe error Correct recipe for having PCB spacing length higher
than PCB hole max length.
Loss Conveyor
Parameters
Conveyor parameters lost
Recalibrate the conveyor (refer to the TC V3 Operations
Manual).
Dropped Board Alarm
Board dropped
1. Stop the Oven.
2. Open it.
3. Remove the board.
Photo cell defective
Adjust the sensor (refer to the Conveyor Counter Cell
Adjustment procedure)
Check the wiring.
