Remedy
• Check that power is switched on and cables are
plugged in.
• Replace fuse.
• Check fuses on PCB and replace.
• Connect controller.
• Install a phase-reversing cable between the con-
troller and the first fixture on the link.
• Check data quality (page 13). If much under 100
percent, the problem may be a bad data link con-
nection, poor quality or broken cabling, missing
termination, or a defective fixture disturbing the
link.
• Inspect connections and cables. Correct poor
connections. Repair or replace damaged cables.
• Insert termination plug in output jack of the last
fixture on the link.
• Check address setting.
• Bypass one fixture at a time until normal opera-
tion is regained: unplug both connectors and con-
nect them directly together.
• Have the defective fixture serviced by a qualified
technician.
• Install a phase-reversing cable between the fix-
tures or swap pins 2 and 3 in the fixture that
behaves erratically.
• Contact Martin technician for service if the prob-
lem persists.
• Disconnect fixture. Check settings (page 8) and
correct if necessary.
• Disconnect fixture and replace lamp.
• Allow fixture to cool.
• Clean fan.
• Make sure air vents at control panel and front lens
are not blocked.
• Turn up the air conditioning.
• Disconnect fixture. Check settings (page 8) and
correct if necessary.
