INSTALLATION PROCEDURES – ELECTRICAL:
General Comments
The interface cable between the computer and integrated camera system is important to the reliable operation of any motorized instrument positioning system. Selection
of the type of cable, the size (AWG), the number of conductors required, grounding techniques, special consideration for wiring to the devices mounted on the pan/tilt unit,
plug connections and the pan/tilt options are the topics covered in this Section.
Wire Selection
Careful consideration should be given to the type of cable utilized in order to achieve long-term reliability and avoid costly system modifications. The type of cable instal-
lation, such as, underground, overhead, pole mounted generally requires cable designed for the specific application. In addition, the wire may have to be run in conduit.
Check your local electrical code. Adequate wire size insures that sufficient voltage will reach the pan/tilt motors, which will provide the required torque to move the camera.
One factor that influence the wire size is the distance between the power supply and the pan/tilt unit. The current draw is approximately 5.625 amps (135 W @ 24VDC)
with a dual camera system. Size the connecting wires to minimize voltage drop to the positioner based on distance from the power source.
Mating Connector Installations
Pan / Tilt Site - A mating connector is provided. Carefully solder the cable leads to the Pan / Tilt mating receptacle pins. Refer to the appropriate schematic and / or
connector diagram.

INSTALLING / UNINSTALLING CAMERA ASSEMBLY
The GeminEye system should have arrived with the camera systems installed. In the event that a camera system must be removed or reinstalled, please follow these instructions:
To detach a camera module:
1.
Turn off power to the system.
2.
Remove the locking screw at the rear of the camera module on the stainless steel plate. The screw has a 1/4" head.
3.
Slide the stainless steel locking plate toward the rear.
4.
Separate the camera from the positioner by gently pulling outward. Use caution to not pull on the connector once the module pulls away.
5.
Disconnect the electrical cable by turning the connector sleeve counter clockwise.
To attach the camera module to the GeminEye, reverse the above process:
1.
Turn off power, then connect camera cable to mating plug in camera module.
2.
Stainless steel locking plate must be retracted in direction shown.
3.
Camera module is oriented for the hole in the locking plate to line up with the hole in the camera module. Apply pressure to compress the sealing gasket by
pressing the camera housing toward the GeminEye center section. Engage the locking plate by sliding toward the pivot axis of the camera housing. Install
retaining screw at rear of locking plate.
4.
For daylight cameras, clean front window glass before installing GeminEye system.
5.
Test total camera, lens, positioner functions before installing on mount.
INTERNAL ACCESS & ADJUSTMENT
NOTE: Normal operation and maintenance do not require opening the unit. The belt drive system requires no lubrication, and the bearings are lubricated and sealed. No
opening of the positioner for adjustment or inspection is required.
