Problem 1: Cabinet does not start (LCD, button, fan light, and socket are inoperative)
Cause Corrective Action
Power Failure
•
Check if there is power at the wall/building electrical socket by using DVM.
•
Ensure the building socket switch is at ON position.
Power cord is not
connected properly
or faulty
•
Check whether power cord has been connected properly into wall/building socket
and the unit. Some cabinets have 2 cords.
•
Measure the AC voltage between the live and the neutral terminal of the cord by
using DVM.
•
If the voltage is not within ±2% of the wall socket voltage, replace cord; otherwise
proceed to next step
Circuit breaker has
tripped
•
See Component Layout to find circuit breaker.
•
Check the circuit breaker inside the electrical panel.
NOTE: If circuit breaker has tripped, do not reset the breaker before checking all electrical
components and wiring connections. (See Figure 1 ‐ 1).
•
Does the cabinet operate correctly after resetting the circuit breaker? If not proceed
to next step.
Improper
connection
•
Ensure cabinet is plugged in to the main supply.
•
Carefully measure AC voltage between LIVE and NEUTRAL terminal block inside
electrical box (See Figure 1 ‐ 2).
•
The voltage should be 230VAC ±10% for ADC ‐ __1/3 or 115VAC ±10% for ADC ‐ __2.
•
If the voltage is out of the range, check cable connection at connector A pin 1 (live) ,
2 (neutral) and 3 (ground). Confirm that the voltage is present
•
See Component Layout to locate connector A and the pin numbering system.
