Remedy
·Check that power is switched on and
cables are plugged in.
·Replace fuse.
·Connect controller.
·Install a phase reversing cable
between the controller and the first
fixture on the link.
·Check data quality. If much lower
than 100 percent, the problem may
be a bad data link connection, poor
quality or broken cables, missing
termination plug, 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 operation is regained: unplug
both connectors and connect them
directly together.
·Have the defective fixture serviced by
a qualified technician.
·Install a phase-reversing cable
between the fixtures or swap pin 2
and 3 in the fixture, that behaves
erratically.
·Contact a technician for servicing if
the problem persists.
·Disconnect fixture. Check settings
(page 9) 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 9) and correct if necessary.
