MAINTENANCE AND

BASIC SERVICE OPERATIONS

The MAC 600/E requires regular maintenance to keep performing at its optimum. The maintenance schedule will be depen-

dent upon the operating environment. Dirty lenses and filters reduce the light’s brightness. Cooling fans covered by dust may

cause overheating, thus causing the thermostat to cut out the lamp intermittently. This section takes you through the general

maintenance procedures and describes some basic service operations.

WARNING!

All service procedures that require removing covers shall be performed

by a qualified technician.

Disconnect from AC power before removing any cover or part.

Removing the printed circuit board

1. Disconnect the fixture from AC power.

2. Remove the flat plate from the top of the front side of the base. Do not remove the curved side plates.

3. Unplug the white plastic wire connectors from the top of the printed circuit board. To unplug a connec-

tor, hold the plastic connector - never pull the wires - and pull it straight off the pins.

4. Grasp the black pins on either end of the circuit board and gently pull it out. You may have to guide

some wires past the motor housing. Be careful not to knock the copper heat sinks.

Replacing the printed circuit board

1. Gently put the circuit board back into the base. You may have to guide

some wires past the motor housing. Push the black pins down to lock the

board in place.

2. Reconnect the wire connectors. Each connector (except for the 2 fan

connectors and the control module connector) is labelled. Fit the female

over the male with the “rails” on the female connector over the “tongue”

on the male connector. Your MAC 600/E may or may not have unused

connectors PL301 and PL302. Starting from the end with the copper heat sinks, the connection order

is:
