Please Note: Hold STOP button for 3-5 seconds while in programming
mode to reverse motor direction.
Please Note: When ordering a motor with internal Low Voltage
Controller, if case ships separately from contents, case
includes 25' cable and special low voltage switch.
1. Connect ILT switch to motor via terminal blocks, or via modular port
using four conductor modular cable. When using modular cable,
cable connectors MUST NOT be crimped in reverse, as with standard
telephone cable.
(For Dry Contacts Wiring Diagram, see Section 12.)
2. Set slide switch to lower position. Hold DOWN button to move viewing
surface to desired lower limit. If screen moves in opposite direction,
release DOWN button and hold STOP button for 4 seconds. This
reverses operation of UP and DOWN switches.
3. Move slider switch into center position. Wait several seconds.
Please Note: Move slider switch from down to up in one motion to set
limits in same position.
4. Set slide switch to higher position. Move viewing surface to desired
upper limit by holding UP button on wall switch.
5. Return slide switch to center position to return to normal operation.
