Proceed with caution - 110 volt A.C. trouble-shooting. If
there is no A. C. then power down the circuit and trace it back by
continuity checking, through the circuit. Check the disconnect,
overload protector, timer relay switch and stop push button.
Repair or replace any components if necessary. Check the timer
relay to be sure it is set at a two second delay.
Go to the RAF 100 Box and take a reading on the red terminal
#3 and ground as you would for a light problem, you should have 25
volts D. C. see page 5-009. Caution again must be noted as you
work inside the box. If you do not have that reading in voltage,
then check the cable leading from the Controller to the RAF 100
Box. Repair or replace it if necessary. If you have the 25 volts,
then jumper (being careful and using an insulated jumper wire) ,
the (black) #1 terminal to the chassis, (Caution A. C. Voltage);
that controls the Drapery on the Light Module Board, and see if
that activates it. If this works then replace the Light Module
Board and Triac. Shut off the power then turn it back on again
after you have finished.
F. Miscellaneous Problems
Background Music will not Mute - relay in the DBX Box may be
bad, repair or replace it. It may just be the diode across pins 7
and 8 on the relay, so check that first before replacing the
relay, see pages 5-019 thru 5-025.
If it does not switch then verify that the cable is good by
checking the voltage across the pins. If the cable is good,
replace the Q1 Transistor on the Houselight Dimmer Board. If that
still doesn't work, then replace the Houselight Dimmer Board.
Dual Pressure Manifold does not operate - If the Dual
Pressure Manifold does not operate, be sure it is not in the
mechanical end first. Manually activate the Dual Pressure with
the manual override switch located on the manifold, see the
Mechanical guide, Part 3 pages 3-004.
Pin up either bit 40 in the top drawer or bit 60 in the
bottom drawer, (both bits must be operable in order for it to
function), as you would for any other movement, see bit chart for
the procedure pages 5-037 thru 5-046. If that works then repair
or replace the Long Driver Board.
If you have pinned up the bit and it doesn't work then take a
reading on the output of the gray wire jumpering the top and
bottom drawers together. If there is 25v. there, then trace the
cable back toward the Dual Pressure Manifold separating the cable
at the connectors, checking the voltage between the pins to find
if there is a break or a poorly seated connector.
