VIS1 VELLEMAN 4
• Connecting the Scanner to the Central Unit
The power cable of the scanner can be connected to the connections at the back of the central unit (the scanner
uses a 24VAC power supply) for independent and automatic operation. Connect the cores of the cable as shown in
the table (see above).
• Installing the Limit Stops
The toothed wheel is slotted at intervals of 5°. The coiled (extension) cord with BNC connector is connected to the
rear of the scanner. The reversing switch activator (1 in fig. 1 at the back of the manual) is visible between the
toothed wheel and the housing on the front side of the unit.
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.
