Operation
Temperature sensor error
Rotation sensor error
Speed detection error
If there was a problem during heating in a step at the end of the program, the control will show “Temperature sensor error”. The temperature was never reached in this cycle.
Possible Faults:
●Bad temperature probe.
●Wiring to electrical or steam heating relay has failed.
●Electrical heating elements or steam valve is broken.
NOTE: If the cycle aborted, it may be due to a temperature sensor error.
The control did not sense any pulses or the control sensed wrong pulses from the rpm sensor.
Possible Faults:
●Rpm sensor is broken.
●Distance from rpm sensor to pulley is too large (>2mm).
●Bad motor.
●
●Problems with the inverter.
●Wiring connection is bad.
An error occurred at the end of a spin stop or during coast down, where the rpm sensor suddenly failed to give output pulses.
Possible Faults:
●Rpm sensor failure.
●Rpm sensor dislocated (too far from pulley).
●Broken
●Wiring disconnected.
