IV. MAINTENANCE
EXPLOSION HAZARD — Do not disconnect the equipment while
the circuit is live or unless the area is known to be free of ignitable
concentrations.
EXPLOSION HAZARD — Substitution of any component may impair
suitability for Class I, Division 2.
Listed below are some important safety instructions and precautions you should
follow:
• Read and understand all instructions before operating this system.
• Any maintenance to the light system must be done with the power
turned off.
• Any maintenance to the light system must be performed by a trained
electrician in accordance with all applicable national and local codes in
the country of use.
• Never alter the unit in any manner. The safety of the unit may be com-
promised if additional openings or other alterations are made.
• The nameplate should not be obscured. It contains cautionary and/or
other information of importance to maintenance personnel. Ensure the
nameplate remains readable if the housing's exterior is painted.
• If the glass dome is damaged in any way, it MUST be replaced.
• After performing any maintenance, test the light system to ensure that
it is operating properly.
Failure to follow all safety precautions and instructions may result in property
damage, serious injury, or death.
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 continu-
ously or darken to a point beyond that shown in Figure 3, it should be replaced.
SHOCK HAZARD — Strobe and HID light systems generate high
voltages. Disconnect power from the strobe system and wait at least
5 minutes before opening the unit. Do not apply power to the unit
while the unit is open. Failure to follow this warning could result in
serious injury or death.
