Remedy

cables are plugged in
● Replace the 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 %, 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

● 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
● Allow the fixture to cool down
● Clean the fans
● Make sure air vents are not blocked
● Turn up the air conditioning

dealer
