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 (located near mains
inlet). Disconnect fixture and replace fuse.
Secondary fuse(s) blown (located on
PCB inside base). Disconnect fixture. Check fuses on PCB and
replace.
Fixtures reset correctly but
respond erratically or not at
all to the controller. Bad data link. Inspect connections and cables. Correct poor
connections. Repair or replace damaged
cables.
Data link not terminated. Insert termination plug in output jack of the
last fixture on the link.
Incorrect addressing of the fixtures. Check fixture address and protocol settings.
One of the fixtures is defective and
disturbs data transmission on the link. Bypass one fixture at a time until normal
operation is regained: unplug the XLR in and
out connectors and connect them directly
together. Have the fixture serviced by a
qualified technician.

(pins 2 and 3 reversed). Install a phase-reversing cable between the
fixtures or swap pins 2 and 3 in the fixture that
behaves erratically.

match local AC voltage. Disconnect fixture. Check the fixture’s internal
power supply switch is set to the correct AC
supply voltage.
