Solution
● Check if power is switched on
and cables are plugged in.
● Return the device to your
Showtec dealer.
● 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 restored:
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 fan.
● Make sure air vents in control
panel and the front lens are not
blocked.
● Turn up the air conditioning.
● Disconnect the fixture and return
it to your dealer.
● Disconnect fixture. Check settings
and correct if necessary.
