Avantra 36/44 Service Manual
Before connecting the processor to the local electrical power source, determine
whether the unit requires any internal wiring modifications. Processor input
wiring connections are located in the electronics compartment beneath the dryer
section.
Power Transformer Primary Tap Connections
The power transformer, located near the power triacs, has three alternate
primary tap connections to accomodate variations in the ac supply voltage. Refer
to Figure 1-13.
Figure 1-13 Power transformer primary tap connections.
• If the supply voltage, as measured between L1 and L2, is higher than
240VAC, disconnect the wire from the #5 position (220VAC) and reconnect
it to the #6 position (240VAC).
• If the supply voltage is between 220 and 240VAC, leave the connection as
is (#5, 220VAC).
• If the supply voltage measures below 220VAC, disconnect the wire from
the #5 position (220VAC) and reconnect it to the #4 position (200VAC).
Operation on 400/415V 3N~50/60HZ
The processor is wired at the factory for operation on 400/415V 3N~50/60Hz,
plus ground line. See the top connection diagram in Figure 1-14 below. If this is
the available power source, then the processor requires no wiring modifications.
Rewiring for other Operations
NOTE: If the OLP is being installed in the U.S., the OLP will need to
be rewired.
The unit ships wired for 400/415V 3N~50/60Hz. To modify the processor wiring
remove the rear panel to gain access to the electrical compartment. Refer to the
diagrams in Figure 1-14 for the following Wiring Configurations:
• 400/415V 2N~50/60Hz
• 230-240V N~50/60Hz
• 208-240V three phase~50/60Hz
• 208-240V single phase~50/60Hz
