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 (page 8) 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 (page 8) and
correct if necessary.
