A.
Flash Tube Replacement.
As strobe lights are used, the flash tubes begin to darken, causing the light output to
decrease. This darkening is characteristic of flash tubes. The darkening will begin near the base of
the tube and progress upward. In addition, as flash tubes age, they may have a tendency to misfire
(not fire periodically).
After extended operation, occasionally check for flash tube degradation. Should the flash
tube misfire, have a noticeable decrease in light output, glow continuously or darken to a point
beyond that shown in Figure 2 — it should be replaced.
High voltages are present inside the light assembly. Wait at least 5 minutes after
shutting off the power before servicing this unit.
To change the flash tube, proceed as follows:
1.
Disconnect power.
2.
Loosen the setscrew, located on the globe-and holder assembly.
3.
Grasp the top of the dome and push down while turning the dome counterclockwise
approximately 3/4-inch (19 mm).
Effectiveness of hazardous location enclosure must be maintained. Do not damage globe
or threads while disassembling or reassembling unit. Lubricated joints exposed for long
periods of time may attract small particles of dirt or other foreign materials. Body and
cover joints should be reassembled immediately.
4.
Gently lift dome away. Ensure that the gasket between the dome and base is not
lost.
