Wiring Connections
The rotator unit must be wired to the
control unit with 4-wire cable. The
gauge of the 4-wire cable to connect the
control unit to the rotator depends upon
the distance between rotator and
controller. The wire for the impulse
sensing may be quite thin - #22 or similar, even for relatively long
distances.
Length Gauge Motor
10 m (32') #18 (1.19 mm)
