operating system is received from the DMX200 unit.
Step 7. Tilt all luminaires parallel to the floor and start all lamps if not already struck.

problem may be in lamp or connections to lamp. Refer to appropriate luminaire user’s
manual for troubleshooting procedures.
Step 9. Perform visual check of the system. Note any lamps that have not started or appear dim or
discolored.
a. If lamp appears unusually dim after three minutes, douse lamp, wait five minutes, and
recheck lamp mounting. Ensure that lamp is securely seated in its socket and oriented
properly. Unusually dim luminaires may need to have lamp replaced. Refer to
appropriate luminaire user’s manual for lamp replacement procedure.
b. If any lamps still do not start, replace it. If new lamp does not start, problem may be
power supply.
Step 10. Perform diagnostic cues for each luminaire.
