1. Connect ILT switch to motor via terminal blocks, or via modular
port using a 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 p.7.)
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 slide switch into center position. Wait several seconds.
