N 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 or power controller that you
are using.
For screen controllers that require momentary closure between
the up, down, and common terminals to stop the screen in its
current position (e.g Da Lite and Draper), use the included
diodes (1N4001 or equivalent) between the up and common
(1 & 3) and down and common (2 & 3) terminals for reverse
bias protection.
