WIRING AND CHECK-OUT
A. Decide the wire gauge (size) required and
procure the number of feet of the proper cable
(see Table 1).
Maximum Gauge for Gauge for
Length Terminals 1 & 2 Terminals 3-8
125' (38 m) #18 (1.19 mm) #20 (.97 mm)
200' (61 m) #16 (1.42 mm) #18 (1.19 mm)
300' (91 m) #14 (1.75 mm) #16 (1.42 mm)
Table 1
D. With the rotator sitting in the upright position
and connected to the control unit by the 8-
wire cable, plug the control unit power cord
into a receptacle.
E. Turn the power switch on. The meter should
be illuminated.
F. Depress the "Brake Release" (center) lever,
then release it. An audible click should be
heard in the rotator. This is the solenoid
operating the brake wedge.
NOTE: The specifications call for heavier
gauge wire in two locations. Leads #1 and #2
must be heavier gauge and less total lead
resistance.
B. Assemble the rotor cable as shown in Figure
1.
G. Depress the "Brake Release" (center) lever,
hold it, and simultaneously depress the
CCW direction switch (left). The rotator
should turn CCW (looking from the top).
This is S-E-NW-S. Release the CCW
direction switch; the rotator will coast down
and stop. Now release the brake switch. The
rotator is now locked into position.
CAUTION
Shorts between terminals or grounded leads may
damage the rotator.
:
H. Repeat the previous step for CW direction by
depressing the brake switch first, then the
CW direction switch (right).
C. Temporarily attach the 4 1/4"-20 x 1 1/4"
screws (Item 147) to the bottom of the rotor
unit.

CAUTION
It is best to release the direction switch just
prior to the end of rotation (extreme CW or
CCW position) in order not to cause undue
stress on the stop arm and/or the gears.
