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.

approx. 1' below
desired setting and
turn off.
2.
With Up switch on,
turn UP
(II)
limit screw
counterclockwise
(3 screw turns =
