o 3. Assure that preliminary adjustment of the following items has been
performed:
- Potentiometer adjustments as described in Chapter 5.
- S1, S2 and SW1 switch settings as described in Chapter 5.
Important: The above adjustments must be performed before
proceeding.
o 4. Assure that the controller circuit breaker (MCB) OFF.
o 5. Apply power to the transformer, but Do Not enable the controller or
energize the line/DB contactor (M).
o 6. Using a voltmeter, verify that the voltages listed below are present at
the locations shown. The tolerance for all voltages is
±
10%. Clear
faults before replacing any blown fuses.
Location Voltage
TB5-4 to TB5-5 230V AC
TB5-4 to TB5-6 230V AC
TB5-5 to TB5-6 230V AC
TB4-19 to TB4-20 18V AC
TB4-21 to TB4-20 18V AC

o 7. Remove all power to the transformer.
o 8. The wires connected to terminals 9 and 10 of TB2 must be marked
and removed to allow for local operation of the Enable circuit.
Connect a suitable temporary switch between these terminals and
