DESCRIPTION

The PS7 and PS7-24 “mini” scanners are light-duty indoor scanning units designed to oper­ate with a maximum load of 15 pounds (7 kg.).

The PS7 is a 120 VAC continuous-duty scanner. The PS7-24 is a 24 VAC scanner capable
of either automatic or manual operation when used with a remote control unit or continuous­duty operation when voltage is supplied directly to the scanner. External limit stops allow for
pan rotation up to 320 degrees.

MODELS

PS7 Light-duty “mini” scanner, 120 VAC (UL)
PS7-24 Light-duty “mini” scanner, 24 VAC (CE, UL)

INSTALLATION

The following parts are supplied:
1 PS7 Scanner with six-foot cord or

PS7-24 Scanner with eight-foot cable
1 Adapter plate
3 10-32 mounting screws
3 Internal tooth lock washer
1 Allen hex key

Pelco Manual C350M-H (10/99) 3

CAUTION:

The
PS7 Series Scanner
is designed to

operate upright or inverted.
Do not mount horizontally.

MOUNTING

Make sure the mounting surface can support four times the combined weight of the scanner
and the camera and lens or enclosure, camera, and lens. Refer to the manuals for your en­closure, camera, and lens for the weights of those units. The weight of the camera and lens
or enclosure, camera and lens must not exceed 15 pounds (7 kg).

To mount the scanner directly to a solid surface, attach the adapter plate to the scanner
with the three 10-32 mounting screws provided. Fasten the adapter plate to the solid sur­face using four number 10 scre ws or other suitable fasteners.

If you use a wall, or ceiling/pedestal mount, follow the instructions that are provided with the
mount and then attach the scanner to the mount with the three 10-32 mounting screws sup­plied.

CAMERA/ENCLOSURE MOUNTING

To mount a camera or enclosure, lift the tilt table. Center (balance) the camera and lens or
enclosure, camera and lens load on the tilt table. Adjust the position as needed to align the
mounting holes. A 1/4-20 hex head bolt (not supplied) is required to mount the camera to
the tilt table. Secure the load to the tilt table. Manually adjust tilt table to desired angle and
tighten. Make all necessary electrical connections. To wire the camera and lens or camera
enclosure, refer to the manuals for that equipment.

ELECTRICAL INSTALLATION

This section provides instructions for wiring the scanner only.

PS7

The PS7 is supplied with a six-foot line cord. Plug the line cord directly into a standard
120 VA C outlet.

PS7-24
Remote Control - Connect the eight-foot cable to a terminal strip. Run a matching

cable from the terminal strip to the scanner control. Refer to the wiring diagram in Figure 1.
For inverted operation, reverse the left and right wires.

Refer to Table A for cable distances. The maximum distance is B. If you are using a relay
box, the maximum distance is A plus B.

Continuous-Duty Operation - Connect the COMMON and AUTO wires to a 24 VAC
power supply. Ground the green wire to the closest available ground. Refer to the wiring dia­gram in Figure 1. Refer to distance B in Table A for cable distances.

WARNING:

Do
not operate the
scanner without

limit stops. Do not attempt to
adjust the limit stops while
the unit is operating.
Personal injury or damage
to the unit may result. Do not
remove or reposition the
fixed limit stop on the
scanner. DAMAGE WILL
OCCUR.

LIMIT STOP ADJUSTMENTS

To set pan limit stops, perform the following steps. Refer to Figure 2.

1. Loosen the pan limit stops.

2. Operate the scanner. Pan the unit to the right until the desired right pan limit is
reached.

3. Move the right pan limit stop until it touches the pan limit switch actuator. Push the
stop against the actuator until it clicks, indicating that the limit switch has opened.
Lock the stop in place.

4. Pan the unit to the desired left position. Adjust the left pan limit stop as described in
step 3.

5. Pan left and right to both limit stops and check for exact positioning. Tighten both stops
securely.

MAINTENANCE

Under normal operating conditions and usage, maintenance of this equipment is not neces­sary. Scanners in the PS7 Series require no lubrication, and the motors are both clutch and
impedance protected from overload. The outside of the scanner may be cleaned by wiping
with a dry cloth or spraying with clean air pressure. Do not use spray cleaners or water.
