If the relay has not been pulled,
check that the over-
temperature sensor (CTC-
320/650 A, CTC-1200 A, MTC-
320/650 A) or the short circuit
connector (CTC-320/650 B)
has been mounted and is OK.
If the sensor/switch is OK,
change and adjust the POWER
PCB.
• If the 2 light diodes on the
POWER PCB are lit, change
and adjust the POWER PCB.
• CTC-1200 A only
Check voltage between CN3
pin 5 and 6 on Power PCB.
If the voltage is higher than
0.6V, change the Power PCB.
Defective CONTROLLER PCB:
If the 2 light diodes on the
POWER PCB are not lit,
measure the voltage on CN3
between terminal 3(+) and
terminal 4(-), terminal 5(+) and
terminal 6(-) and between
terminal 9(+) and terminal 10
(-).
If the first two voltages are less
than 0.6V and the last voltage
is less than 1V, change
CONTROLLER PCB and adjust
and re-calibrate the calibrator. If
not, change and adjust the
POWER PCB.
