load, then power supply components, wiring or shorts may
be the problem. Perform visual inspection of power supply
components and wiring. Retest power supply. Replace
power supply if necessary.
Unit Blows Fuses & Bulbs
If power supply blows fuses and bulbs but checks OK
without a bulb installed, the power supply DC current
regulator is not working. Replace power supply.
Bulb Fails to Ignite (Power is on, fans running and front panel illuminated.)
Verify the proper installation of the bulb/reflector assembly.
Check both lamp connections and ensure the lamp
connector is properly plugged in.
Turn the unit off for 20 seconds, and then restart. Repeat
this procedure until the lamp lights, not to exceed five
attempts.
Replace bulb. If still no lamp ignition, replace power supply.
Shutter does not Open Verify footswitch is plugged in (if applicable) and is in proper
operation following procedures in section 9.5. above. Turn
power OFF. Remove bottom cover. Disconnect solenoid
connector from main harness.
Verify shutter is mechanically free & operable by lifting
shutter from rest and allowing it to return. If broken, stuck or
pinching at friction point, adjust fasteners to relieve friction
or replace.
Verify that the lightguide is properly pushed into the
lightguide socket and that the ball plunger is in the detent
groove. MKIII unit safety system disallows shutter operation
if no lightguide is sensed by interlock switch within
nosepiece.
Set the unit to "Manual" mode. Turn the power ON. With a
DC voltmeter, verify 24 VDC are present on the harness
side of the solenoid connector and the footswitch is
depressed. If no power is present, replace the harness. If
power is present, replace the solenoid.
Low UV Output
Confirm all elements of optical train (bulb, reflector, shutter,
and IR filter) are intact and functioning correctly by taking
