technical support team via the following web site www.Barco.com/esupport.

1.3 Validating the correct orientation of the magnet in the manual

XL Lamp House

Contact the Barco helpdesk to receive the caliber magnet.

Image 1-1

To validate the correct orientation of the magnet, the XL Lamp House

must be removed from the projector. This procedure assumes that the

Lamp House is already removed from the projector.

Necessary tools

• Caliber magnet (north side of the magnet is painted in red)

• 3 mm Allen wrench

How to validate a manual Lamp House?

1. Position the Lamp House on a ﬂat and stable table, with the UV ﬁlter side resting on

the table.

The magnet is located (1) on the bottom side of the Lamp House near the handle, but is

not visible at this moment.

2. To validate the magnet orientation, approach the red side (2) of the caliber magnet to

the left side of the Lamp House magnet.

- If the caliber magnet attracts to the Lamp House, the magnet is oriented correctly.

Nothing needs to be done.

- If the caliber magnet repels from the Lamp House, the magnet is oriented incorrectly.

6. After correcting the orientation of the magnet the lamp arc behavior can be different. A

realignment of the lamp in its reﬂector is necessary. See service manual of your projector

for the detailed procedure.
