perform its intended function.
TROUBLESHOOTING
The Controlmaster is designed to resist the hard treatment of touring use. It can even
withstand overvoltages and short circuits. Often what appears to be a problem with the
dimmer is something else. A review of the following may save you a long distance phone
call, or the cost of shipping and/or repair. Even if something is still wrong, this process
will help you explain the malfunction to a service technician.
There are some basic checks that you can do to help isolate a problem. The two forms
of malfunction common to solid state dimmers are: FAILED OFF, in which the lights do
not come on, and FAILED ON, in which the lights cannot be turned off. If your system
has FAILED OFF, check that a lamp load is connected and that the lamp is not burned
out. Verify that the primary power is live and that the dimmer is on (all LED's are
glowing). If either green LED is off, check fuses on the main circuit board.
If the dimmer is operating, check the channel fuses. Make sure the loads are plugged
in and that all extension cords are continuous, and that they go to the loads you think
they do.
Check load circuits by plugging them into regular wall outlets. If the dimmer is getting
power and the loads check out, you may not be getting proper control operation. Check
that the control cable is intact, and plugged in at both ends. The POWER ON light in the
control console should light up.
FAILED ON dimmers will stay on regardless of the control setting. Unplug the control
console from the Controlmaster. If the failure goes away, the cable or console is at
fault. If the channel remains on, the Triac circuit has failed and must be repaired.
Contact your dealer or the factory for this repair.
IN CASE OF TROUBLE
In the event of malfunction, recheck all connections and make sure that the unit is
getting power, and that the cables are continuous and connected properly. Check to
see that the black-out switch is off (up) and that the master is up.
If you still cannot get proper operation, you may take your unit back to your dealer.
You may elect to send your unit to the factory, freight prepaid, with a note describing the
specific complaint. VERY IMPORTANT: PLEASE ENCLOSE A NOTE DESCRIBING
THE PROBLEM--EVEN IF YOU HAVE CONTACTED THE FACTORY BY PHONE.
