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.
2.0 DESCRIPTION The PT7700 systems combine an environmental camera enclosure, pan/tilt assembly, and receiver/driver into a single unit that you can install indoors or outdoors. You can install 2/3-inch (1.69 cm) and 1-inch (2.54 cm) format cameras with either fixed focal length lenses or motorized zoom lenses. An adjustable camera sled will accommodate different sizes of cameras and lenses. 2.
3.0 INSTALLATION CAUTION: When unpacking, transporting, or lifting the PT7700 Series systems, DO NOT use the camera enclosure as a handle. Severe damage to the unit can occur. NOTE: To insure proper wiring and operation of your equipment, it is recommended that you test the PT7700 system and its controller in your facility before installing them in the field. Refer to Sections 3.2 through 3.4. 3.1 MOUNTING CAUTION: The PT7700 systems are designed to operate in an upright position only.
NOTE: If the AC power input to your j. On the bottom of the enclosure, remove the vent grill and filters at the front of the enclosure. Replace the grill with one of the vent cover plates that was attached to the camera sled as loose equipment. k. On the bottom of the enclosure, attach the other vent cover plate over the grill at the rear of the enclosure. 3. Mount the camera/lens to the sled with the 1/4-20 Phillips-head screws that are provided in the parts bag.
3.3 WIRING 1. Route the six-foot power/video/control cable through the wall or pedestal mount if applicable. 2. Connect the end of the cable with the 16-pin connector to the mating connector in the base of the pan/tilt unit. 3. Connect the other end of the cable as follows: a. Connect the coax cable to the video input of the controller. b. For models PT7729WX, PT7729WX-1, PT7723WX-1 and PT7729WX-3, connect the Wiretron control wires (refer to Figure 2). c.

3.4 TESTING SYSTEM AND ADJUSTING LIMIT STOPS WARNING: Never remove the limit stops. Do not adjust the limit stops while the unit is moving. You may injure yourself or damage the unit. NOTE: The tilt limit stops are factory set for 0° and -90° from the horizon. To test the system and adjust the limit stops: 1. Loosen the two pan limit stops at the base of the pan/tilt. 2. Turn on power. 3. Test the system by moving the pan/tilt to the left, right, up and down.
4.0 OPERATION Refer to the manual for your control equipment for operating the pan/tilt system. If your enclosure has a thermostatically controlled blower, the thermostat is set to turn the fan on between 77° and 93°F (25° and 34°C) and to turn the fan off between 62° and 78°F (17° and 26°C). If your enclosure has thermostatically controlled heaters or defroster, the thermostat is set to turn them on between 42° and 58°F (6° and 14°C) and to turn them off between 72° and 88°F (22° and 31°C).
5.0 TROUBLESHOOTING Fuses are located inside the left cover of the pan/tilt unit. Fuses F1 (mother board) and F2 (camera) are 2/10-ampere, slow-blow fuses. F3 (pan/tilt) is a 1-ampere, slow-blow fuse. To order fuses F1 and F2, specify the part number FUS2/10SB. To order fuse F3, specify the part number FUS1SB. If you need to return the pan/tilt system and you can not place the camera enclosure in a horizontal position, remove three of the four Allen bolts that attach the enclosure to the tilt shaft.
6.0 MAINTENANCE Perform the following maintenance at six-month (or more often in harsh environments) intervals to prolong the operational life and appearance of the equipment. Window and Filters 1. Clean the window with a mild nonabrasive detergent in water and a soft cloth to maintain picture clarity. 2. If your enclosure has a blower, clean the foam filters as follows: a. On the bottom front of the enclosure, remove the two screws in the vent grill. b. Remove the vent grill and take out the filters.
Tilt Adjustments and Lubrication 10. Remove the plastic cover on the right side of the pan/tilt unit. 11. Refer to Figure 5. Verify that the worm (B) is fully seated in the worm gear (A). If it is not, turn the two nuts (C) to lift the worm. Tighten the two nuts at (D). 12. If necessary, tighten the nut at E to remove any endplay in the worm (B). 13. If you can move the enclosure up and down, but the worm gear (A) does not move, push pin H further into the tilt shaft to eliminate movement. 14.
