INSIDE TERMINAL WIRING EXAMPLES
The information on the following pages cover the most common wiring options:
•
Pushbutton
•
Extend and Retract for Switch or Contacts
•
Remote (RC-10)
•
12 Volt out supply
•
24 Volt out supply
•
Two dry contact closures
•
Voltage Sensing
CAUTION:
Closing the unit while the projector is running or in
the cooling mode will cause premature bulb failure and may dam-
age electrical components.
Pushbutton
Wire for pushbutton operation as follows:
1.
Install a wire between terminal 5 (extend/retract common) and
ground terminal 3 (see Figure 28).
2.
Connect one wire from pushbutton to terminal #4
(12 VDC power supply) and the other wire from the pushbut-
ton to terminal #6 (extend/retract) (see Figure 29).
With the unit plugged in, push the button once and the unit should
extend. Push the button during travel and the unit will stop at that
location. Push the button after the unit is extended or stopped in
mid-travel and the unit will retract.
Extend and Retract Terminals to be Triggered By
Separate Dry Contacts
These terminals can be used with a wall switch or a separate set of
dry contacts for dedicated extend and dedicated retract. Momentary
contacts are preferable.
NOTE: The connection between the ground (#13) and any other
terminal connection must be broken (open) before completing the
next circuit.
1.
Connect the common to terminal #13 (see Figure 30).
2.
Connect the extend to terminal #11 (see Figure 31).
3.
Connect the retract to terminal #12 (see Figure32).
