Pelco C1498M-A operation manual Troubleshooting, Park Time Minutes, Scan Limit Stops

NOTE: On power-up, the auto scan tilt angle will be whatever angle the camera was at when the right scan limit was set.

NOTE: Preset 1 must be programmed for the dome to park.

SCAN LIMIT STOPS

Refer to the documentation for your control system for programming presets, then do the following:

1.Make sure limit stops are turned ON (refer to the Limit Stops section), 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 scan limit stops.

PARK TIME MINUTES
