1.0 GENERAL

1.1 IMPORTANT SAFEGUARDS AND WARNINGS

Prior to installation and use of this product, the following WARNINGS should be
observed.

1. Installation and servicing should only be done by qualified service personnel
and conform to all local codes.

2. Unless the unit is specifically marked as a NEMA Type 3, 3R, 3S, 4, 4X, 6, or
6P enclosure, it is designed for indoor use only and it must not be installed
where exposed to rain and moisture.

3. The weight of the camera, lens, and enclosure shall not exceed 40 lb (18.16 kg),
subject to specific pan/tilt unit.

4. Only use replacement parts recommended by Pelco.

5. After replacement/repair of this unit’s electrical components, conduct a resis­tance measurement between line and exposed parts to verify the exposed
parts have not been connected to line circuitry.

6. The installation method and materials should be capable of supporting four
times the weight of the enclosure, pan/tilt, camera and lens combination.

The product and/or manual may bear the following marks:

This symbol indicates that dangerous voltage constituting a
risk of electric shock is present within this unit.

This symbol indicates that there are important operating and
maintenance instructions in the literature accompanying this
unit.

CAUTION:

RISK OF

ELECTRIC SHOCK.

DO NOT OPEN.

TO REDUCE THE RISK OF ELECTRICAL SHOCK,

DO NOT REMOVE COVER. NO USER-

SERVICEABLE PARTS INSIDE. REFER SERVICING

TO QUALIFIED SERVICE PERSONNEL.

CAUTION:

Please thoroughly familiarize yourself with the information

in this manual prior to installation and operation.

2.0 DESCRIPTION

Pan/tilts in the PT550P Series are designed to remotely position a TV camera in
both the horizontal and vertical attitudes. Pan (horizontal) and tilt (vertical) move­ments are caused by activating small DC motors in the pan/tilt unit. All Pelco units
are equipped with adjustable limits for both pan and tilt, and all motors are equipped
with electrical filtering circuits to suppress RF interference.

The drive motors employ a permanent magnet type of field. The voltages applied
to the armature can be varied in magnitude to change motor speed and are re­versed in polarity to change the direction of movement.

Braking is accomplished by electrically short-circuiting the motor armature. During
normal operation, dynamic braking is accomplished in the control unit by short­circuiting both sides of the armature to the supply common. When a pre-adjusted
limit is encountered during operation, limit switches remove the driving voltage and
apply a short circuit to the motor armature.

3.0 INSTALLATION

CAUTION:

Pan/tilts in
the PT550P Series are
designed for upright or in­ver ted operation and
should never be mounted
horizontally.

NOTE:

When mounting the pan/
tilt outdoors in the inverted position
(base up), RTV silicone sealant,
such as Dow Corning Type 732 or
equivalent, should be applied to the
areas indicated in Figure 1.

Pan/tilts in the PT550P Series are designed to mount onto a horizontal surface in
the upright or inverted position.

In order to ensure proper wiring and system operation of all components, it is rec­ommended that you test the pan/tilt and the associated control equipment in your
facility before field installation. Refer to Sections 3.3 through 3.4.

3.1 MOUNTING

Attach the pan/tilt unit to a mount, following the instructions that accompany the
mount. To ensure maximum pan travel, mount the pan/tilt so that the fix ed limit stop
is directly opposite the center of the intended viewing area.

Make sure the mounting surface and the mounting method is strong enough to sup­port four times the combined weight of the pan/tilt, enclosure, camera and lens.

3.2 CAMERA/ENCLOSURE MOUNTING

Attach the enclosure, camera and lens to the pan/tilt unit with 1/4-20 hardware (not
supplied). The enclosure, camera and lens must be correctly mounted and balanced
on the tilt table for proper operation.

3.3 WIRING

Cable distances for pan and tilt motors should not exceed the distances speci­fied in Table A. Cable fabrication must be in accordance with Section 3.3.1, Mat­ing Connector Assembly . The f ollowing are some recommended common instal­lation practices.

1. Always use jac keted stranded multi-conductor interconnecting cab le between
the control and the pan/tilt unit, with additional conductors than needed for
future servicing and or additions.

2. Always use color-coded conductors f or ease of wiring and to identify functions
at a later date.

3. Keep a wiring diagram with the system for later use and reference.
