2. Check terminal block connections as described in Chapter 5 and
Appendix B.
3. Set switches S1 (A Quad B Board) and SW1 (top of drive) as
explained in Switch Settings in Chapter 5
4. Assure that the drive circuit breaker (MCB), contactor (M) and
Enable input are OFF (de-energized).
5. Apply power to the input transformer primary, but Do Not Enable
the drive or energize the contactor (M). The Enable LED should be
Off.
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. Refer to Chapter 11 for test
point locations.
Location Voltage
TB5-4 to TB5-5 230V AC
TB5-4 to TB5-6 230V AC
TB5-5 to TB5-6 230V AC
TB4-21 to TB4-19 36V AC
TP13 to TP12 +12V DC
TP14 to TP12 –12V DC
7. Remove all power to the transformer.
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
insulate the switch connections.
9. Once control connections are made:
a) Open the enable switch – the ENABLE LED will be Off.
b) Apply power to the transformer primary.
c) Place the circuit breaker (MCB) to the On position.
d) Energize the contactor (M). The STATUS LED should illuminate
to a steady green.
Important: If power is applied while the drive is enabled, the
STATUS LED will flash red and disable the drive. The drive may be
reset by removing the Enable signal and momentarily grounding the
Reset terminal (TB2-11). An alternate method would be to remove
and reapply the branch circuit or drive power (36V) with the Enable
input removed.
