Parts/kits listed are now obsolete and are no longer serviceable through Bendix.

ELECTRICAL SYSTEM

POWER AND GROUND (POWER INPUTS)

Electrical power to the Bendix® XVision® Night Vision System is provided through the vehicle harness. The vehicle ignition wire {(A) Red} should be fused to a 3 A slow open fuse (maximum) and connected to the ignition bus of the vehicle. The ground wire {(B) black} should be connected to the ground bus of the vehicle. The headlamp active wire {(C) blue} should be fused to a 1 A fast open fuse (maximum) and connected to the vehicle headlamp circuit. When the headlamps are on, 12V should be present on the blue wire.

WARNING: Vehicle power and headlight circuits MUST be fused. Permanent damage to the display, IR camera, or vehicle electrical system could occur if power to these units is not fused. Eliminating fuses from circuit will void all warranties.

IMPORTANT: When replacing a fuse, it is important to use only the specified fuse with the correct amperage, as listed above. The use of a fuse with a rating other than indicated may result in a dangerous electrical system overload. Repeated opening of a properly rated fuse indicates a problem in the circuit that must be corrected.

FIGURE 18 - XVISION SYSTEM ELECTRICAL SCHEMATIC

The IR camera and display are compatible with 12V DC battery systems with a chassis ground.

OPERATING INPUT VOLTAGE

The IR camera is operational in the temperature range between -40°C to 60°C. Normally, the IR camera takes about 45 seconds to warm up. However, as the external temperature gets closer to the extremes listed, the warm-up time will begin to approach two minutes. Refer to Figure 19.

SERVICING THE XVISION SYSTEM

The following sections provide instructions for maintaining and/or replacing components of the XVision system.

CAMERA MOUNTING BRACKET REPLACEMENT

1.Loosen and remove the four 5/16 in. bolts securing the IR camera bracket to the mounting bracket.

2.Disconnect the camera harnesses (2-pin and 6-pin). Remove the IR camera assembly.

3.From inside the cab, remove all mounting hardware from the mounting bracket.

4.Remove the stud plates, mounting bracket, and shims (if used).

5.Clean the area around the drilled holes in the cab.

6.Align the new mounting bracket with the holes in the cab. Note: use new mounting hardware for the installation.
