Located on the toothed wheel are two adjustable plastic limit stops (2 and 3 in fig. 1). Both limit
stops can be removed, enabling the scanner to rotate 360°.
Perform steps 1 through 5 outlined in "Manual Operation of the Scanner" (see below) to
establish approximate limit stop settings before mounting the camera. At least 1 of the limit
stops should be installed or the scanner will continue its turning motion. Make sure that the
camera covers the required detection area and that the rear of the scanner faces away from the
area to be covered.
Manual Operation of the Scanner
1. Connect the central unit to a standard 220V-outlet, activate the device and put the
"MANUAL/AUTO"-switch in the "MANUAL"-position.
2. Hold the 'LEFT/RIGHT" toggle switch in the "RIGHT"-position until the scanner has reached
the desired right-hand position.
3. Install the first limit stop (2 in fig. 1) just to the right of the switch actuator (1 in fig. 1) by
snapping it in place.
4. Put the "MANUAL/AUTO"-switch in the "MANUAL"-position and hold the "LEFT/RIGHT"-
toggle switch in the "LEFT"-position.
5. Install the second limit stop (3 in fig. 1) to the left of the switch actuator (see step 3).
6. Mount the camera on the scanner. Read "Mounting the Camera" (see below).
7. Have the camera pan to both limits (left and right) to verify the position of the limit stops.
Automatic Operation of the Scanner
1. Connect the power cable to the AC outlet.
2. Put the "AUTO/MANUAL"-switch in the "AUTO"-position, allow the unit to autopan to the
desired right-hand position and then unplug the cable.
3. Install the first limit stop (2 in fig. 1) just to the right of the switch actuator (1 in fig. 1) by
snapping it in place.
4. Plug in the power cable and allow the unit to pan to the desired left-hand position. Unplug the
cable.
5. Install the second limit stop (3 in fig. 1) to the left of the switch actuator (see step 3).
6. Mount the camera on the scanner. Read "Mounting the Camera" (see below).
7. Activate the scanner and check the position of both limit stops.
Mounting the Camera
Do not use an auto-iris lens with this unit. This would cause the iris mechanism to wear very
quickly, as an auto-iris lens constantly compensates for the varying light level.
Use a screw with a locknut to mount the camera. Place this screw in one of three positions (see
5 in fig. 1) in order to obtain the best possible balance.
The scanner has an off-centre pivot which allows the camera to tilt from 10 degrees below
horizon level to 90 degrees above or vice versa, depending on how the camera is mounted (see
figures at the back of the manual). Loosen the hex-head screws (4 in fig. 1) with locknut on the
side of the mounting bracket to adjust the angle of the camera. Retighten the two screws firmly
when the desired angle has been obtained.
