Luminaire Powers Up, But Will Not Calibrate
Assuming the following:
•
Console is powered up and working properly.
•
Repeater unit is properly connected and working.
•
Lamp cable is good.
Step 1.
At VL2B/VL2C lamp input connector, check connection to
lamp run cable. Ensure good connection.
Step 2.
Hard reset luminaire by removing and then resupplying power
to repeater unit.
Step 3.
Check form and function setting.
a. Access motherboard. Refer to Motherboard Removal and
Replacement paragraph.
