Corrections
1.1 Replace damaged cord or repair faulty
connections.
1.2 Reset the circuit breaker and observe if it
trips again, if so check for a short circuit.
1.3
Replace the On/Off Rocker switch.
Have the facilities electrical circuit
upgraded.
Possible cause check-up and tests
1.1 Check that the main power is turned on,
the power cord and the connections to the
circuit breaker.
1.2 Check the circuit breaker. If it is tripped,
there is possibly a short-circuit.
1.3 Check the AC voltages.
— The input voltage comes from the
circuit breaker to the On/Off switch
then to the AC-T1 board – See the
Electrical Wiring Diagram. The voltage
must be 208 VAC.
— With a multimeter check from pin 3 at
the AC-INPUT connector (JP3), on the
AC-T1 board, to pins 1 and 2.
— Turn on the power. The reading must
be the same as the voltage coming from
the wall outlet for the machine. If not:
The On/Off Rocker switch contacts
may be loose.
The electrical circuit supplying the unit
may not be able to handle the load.
10. TROUBLESHOOTING
10.3 Pre-process malfunction
If the malfunction is possibly caused by the electronic system, the following should be
performed prior to any corrective action:
Clean the grid
under the fan with compressed air. This should be done from inside so debris will be blown outwards.
Clean the entire electronic box with compressed air. (dirt can be conductive and possibly causing a short in the circuit)
Symptom
1. No response when the
system is turned on
