The diagrams included here are examples only. Your
equipment may have different wiring requirements.
Refer to the specific wiring instructions provided by the
manufacturer of the screen controller that you are using.
For DaLite and Draper screen controllers, a momentary
closure between either the up and common terminals or
the down and common terminals causes the screen to
move up or move down. A momentary closure between
all three terminals (up, down, and common) stops the
screen in its current position. Use the included diodes
(1N4001 or equivalent) for reverse bias protection.

Draper single motor LVCIII screen controller (part #6300858)
Use 1N4001 or equivalent diodes (100mA maximum
current through the diode, 50V maximum reverse bias)
for the Da Lite and Draper installations shown above.
For Stewart Filmscreen screen controllers, a momentary
closure between the up and common terminals, the down
and common terminals, or the stop and common terminals
will cause the screen to go up, go down, or stop.

MLC relay wiring for an RCM-SCLT
For controllers, a momentary closure between either the
up and common terminals or the down and common
terminals causes the screen to move up or move down. A
latching contact toggles the AC power/lighting (or other)
controller on and off.
