Problem Probable cause(s) Remedy
One or more of the fixtures
is completely dead.
No power to fixture.
• Check that power is switched on and cables are
plugged in.
Primary fuse blown.
• Replace fuse.
Secondary fuse(s) blown (located on
PCB inside base).
• Check fuses on PCB and replace.
Fixtures reset correctly but
all respond erratically or
not at all to the controller.
The controller is not connected.
• Connect controller.
XLR pin-out of the controller does not
match pin-out of the first fixture on the
link (i.e. signal is reversed).
• Install a phase-reversing cable between the con-
troller and the first fixture on the link.
Fixtures reset correctly but
some respond erratically
or not at all to the
controller.
Poor data quality
• 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.
Bad data link connection
• Inspect connections and cables. Correct poor
connections. Repair or replace damaged cables.
Data link not terminated with 120Ω
termination plug.
• Insert termination plug in output jack of the last
fixture on the link.
Incorrect addressing of the fixtures.
• Check address setting.
One of the fixtures is defective and
disturbs data transmission on the link.
• 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.
XLR pin-out on fixtures does not
match (pins 2 and 3 reversed).
• Install a phase-reversing cable between the fix-
tures or swap pins 2 and 3 in the fixture that
behaves erratically.
Shutter closes suddenly. The color wheel, gobo wheel, or a
gobo has lost its index position and the
fixture is resetting the effect.
• Contact Martin technician for service if the prob-
lem persists.
No light and “LERR” error
message displayed.
The power supply settings do not
match local AC voltage and frequency.
• Disconnect fixture. Check settings (“AC power” on
page 7) and correct if necessary.
Lamp missing or blown
• Disconnect fixture and replace lamp.
Lamp cuts out
intermittently.
Fixture is too hot.
• Allow fixture to cool.
• Clean fan.
• Make sure air vents at control panel and front lens
are not blocked.
• Turn up the air conditioning.
The power supply settings do not
match local AC voltage and frequency.
• Disconnect fixture. Check settings (“AC power” on
page 7) and correct if necessary.
