Pelco Manual C332M-D (10/98)

Some common problems encountered with pan/tilt systems include miswiring, over-
loading, and not using the units for the correct application. If the pan/tilt unit fails to
operate, do the following:

1.

Check the fuse in the control unit. If the fuse is bad, replace it.

2.

If the fuse blows after replacing it, check the control cable between the control
unit and the pan/tilt for shorts, high resistance, or opens.

3.

If the control cable is good, reconnect it to the control unit but not to the pan/tilt.
Replace the fuse and operate the control unit. If the fuse blows again, the fault
is in the control.

Refer to Figure 3 for the following steps.

4.

If the control unit is good, check the wiring harness in the pan/tilt for shorts.

5.

If the wiring harness is good, check the motor starting capacitors.

6.

If the starting capacitors are good, check the motors for opens and shorts.
There should be low resistance between the windings.

7.

Check the limit switches for opens and shorts.
