Introduction
A visual inspection of the Pan & Tilt Unit while it is operating will usually reveal
if a problem is mechanical or electrical. Users should become familiar with
the equipment and report any unusual problems before small problems
become major ones. Straightforward, common sense troubleshooting
techniques will usually reveal the source of most problems encountered.
Users should review the following general information to assist in
troubleshooting the Pan & Tilt Unit:
8.2
Mechanical or Electrical
1) Remove the Access Covers
2) Actuate a movement using the Emulator/GUI software to determine if the
Drive Motor is running. If the motor is running, the problem is usually
mechanical. If the motor is not running, the problem can be either
mechanical or electrical.
3) Mechanically uncouple the motor by removing the Drive Chain from the
sprocket.
NOTE
If the motor operates, the problem is usually mechanical (binding Worm
Drive Gears, Drive Chain tension was too strong, etc.).
