630
Sensor Opened
(Heating Station 2)
An abnormal value was input to the signal amplification part of the
controller board due to a disconnected temperature sensor.
Contact the Sakura Finetek
Technical Support
representative or local
representative.
The heating station connection harness connecting the temperature
controller board and the controller board was disconnected.
A disconnected harness was recognized by CPU1 due to a signal
amplification error of the controller board.
Normal judgment was disabled due to a CPU1 error of the controller
board.
631
Sensor Shorted
(Heating Station 1)
An abnormal value was input to the signal amplification part of the
controller board due to a shorted temperature sensor.
Contact the Sakura Finetek
Technical Support
representative or local
representative.
The heating station connection harness connecting the temperature
controller board and the controller board shorted.
A shorted harness was recognized by CPU1 due to a signal
amplification error of the controller board.
Normal judgment was disabled due to a CPU1 error of the controller
board.
632
Temperature Low
(Heating Station 1)
Power could not be supplied to the heater due to a disconnection or
connection failure of the heater.
Contact the Sakura Finetek
Technical Support
representative or local
representative.

Station 1)
The SSR3 on the temperature controller board experienced a short-
circuit failure.
Contact the Sakura Finetek
Technical Support
representative or local
representative.
The heater remained on due to a driver error of the controller board.
A false detection occurred due to an error of the SSR1 for power-
supply voltage detection.
The heating station connection harness connecting the temperature
controller board and the controller board was disconnected.
The instrument malfunctioned due to an over-temperature protection
input error of the controller board.
The heater voltage selector switch is set incorrectly.
The power-supply voltage selector switch is set incorrectly.
