30 MAC 250 Krypton/Entour

FAN

To maintain adequate cooling it is important that the fan be cleaned regularly. It can be cleaned with a soft

brush, vacuum, or compressed air.

Lubrication

The MAC 250 Krypton/Entour does not require lubrication under normal circumstances. The slides and

spindle for the focus lens car are lubricated with a long-lasting Teflon-based lubricant that can be reapplied

by a Martin service partner in the unlikely event that this should be necessary.

Replacing fuses

MAIN FUSE

The main fuse holder is built in to the mains input socket. Never replace the fuse with one of a different

rating!

1 Unplug the mains cable from the input socket.

2 Pry open the fuse holder and remove the fuse.

3 Replace the fuse with one of the same type and rating. The fuse rating is listed on serial number label.

4 Close the fuse holder and replace the mains cable.

POWER SUPPLY FUSES

There are two fuses for the low-voltage power supplies located on the printed circuit board. If one or more of

the green LEDs on the PCB does not light, one of these fuses may be blown. If all three LEDs are lit, the

low-voltage power supplies are functioning correctly.

Have the fixture serviced by a Martin service technician if the problem persists.

1 Disconnect the fixture from AC power.

2 Remove the left-side yoke cover (when looking at the head in the text in the upright position from the back

as indicated in the illustration) to access the PCB.

3 Carefully remove and check the two fuses located in the bottom of the PCB (see “Circuit board connections”

on page 45). Replace as necessary with fuses of the same size and rating (see page 46).

4 Re-attach the yoke cover.
