12.2.2 Direct light
Lamp replacement is quite simple with the XDS Direct light. Lamp replacement should normally be
scheduled at factory shutdown intervals, to avoid unexpected downtime during peak production.
Lamp instructions are as follows:
NOTE: The Direct light is using another lamp, 6002 9852.
1. Follow the instructions for lamp replacement in section 11.2.1 position 1-2.
2. Open the measuring head door and find
the lamp. The lamp is very warm. Give it at
least 15 – 20 minutes to cool down before
attempting replacement.
3. Follow the instructions in section 11.2.1, position 5 – 10.
4. Close the door. Apply power to the instrument.
5. Follow the instructions in section 11.2.1, position 14 – 18.
12.3 Fuse Replacement
Fuse Replacement is an unusual event, and usually is caused by some electrical fault. The electrical
fault should always be investigated and repaired before fuse replacement. Once the fault is found
and corrected, this procedure should be followed:
1. Turn off electrical power and follow any
required lockout policy.
