LED Light Module Assembly Replacement Procedures

Time required for this step: Approximately 2 Minutes (4 Minutes for both sides)

Tools required for this step:

Parts involved in this step:

VR-PRO4-05-0001 LED Light Module Assembly

Quantity	Part Number	Part Description
1	VR-PRO4-05-0001	Light Assembly LED Module (Pro 4)

Steps

Note: The following step-by-step instructions apply to one side. Repeat these steps on both sides if you are replacing both LED Light Modules.

1. Place or make sure the O-ring is seated in the groove on the front face of the horizontal thruster tube.

2. Orient the LED light module at the front of the horizontal thruster tube so that the LEDs are facing forward and the notch at the rear of the module is facing toward the main hull. This notch has to engage with the screw that holds the horizontal thruster tube to the main hull.

3. Align the LED light module assembly connector clip with the catch on the ROV wire harness connector for the lights in the horizontal thruster tube.

4. Make sure the wires are inserted into the horizontal thruster tube and will not be pinched by the LED light module when it is inserted.

5. Slide the LED light module into the horizontal thruster tube until it seats against the O-ring in the front face of the horizontal thruster tube.

Tip

VideoRay recommends that you test the LED light module after it is installed and before replacing the light dome.
