Scan Limit Stops
When scan limit stops are set, the pan and tilt reverses direction during random, frame, or auto scanning when a limit stop is reached.
The manual scan limit stops can be set in one of two ways:
At the controller by programming presets 92 and 93
or
At the controller by programming the Limit Stops menu
PRESETS
Refer to the documentation for your control system for programming presets, and then do the following:
1. Make sure limit stops are turned ON, then exit the menu.
2. Push the joystick left until you reach the limit you want the camera to go to on the left.
3. Program preset 92 (25).
4. Push the joystick right to the limit you want the camera to go to on the right.
5. Program preset 93 (26).
Setting presets 92 (25) and 93 (26) to the same point disables manual limit stops.
NOTE: Programming preset 92 (25) disables the scan limit stops until preset 93 (26) is set. Preset 92 is the left scan limit and preset 93 is
the right scan limit.
