AlfaSpid Rotator www.alfaradio.ca Page 6

Wiring Connections

The rotator unit must be wired to the

control unit with 8 wires cable. 4 wires –

azimuth (1,2,3,4) and 4 wires - elevation

(5,6,7,8). Diameter of wires in 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 (distance) Gauge Motor

10 m (32') #18 (1.19 mm)

30 m (100') #16 (1.42 mm)

60 m (200') #14 (1.75 mm)

Remove cover from the rotator and make connections as follows:

Azimuth:

1 Motor Drive to 1 on controller terminal

2 Motor Drive to 2 on controller terminal

3 Impulse Sense to 3 on controller terminal

4 Impulse Sense to 4 on controller terminal

Elevation:

5 Motor Drive to 5 on controller terminal

6 Motor Drive to 6 on controller terminal

7 Impulse Sense to 7 on controller terminal

8 Impulse Sense to 8 on controller terminal

TIP:

Before final installation of

equipment, it is strongly

suggested you check out all

functions and connections on

a workbench.

CAUTION:

Do not accidentally switch

the motor wires with the

impulse wires.
