Operation
Improperly Fastened
Connections
Visually inspect all connections to
and from the Power Supply.
Secure all connections.
Main Line Fuse
Blown
Remove Fuse from Power
Receptacle and check with an
Ohmmeter.
Replace Fuse, if defective.
Corroded Lamp
Bases
Visually inspect the Lamp Bases for
ANY signs of corrosion.
Replace the Lamp Bases if
corrosion exists (both Lamp Bases
should be replaced at the same
time).
Lamp Beyond Useful
Life
Replace Lamp with known good
Lamp and re-test unit.
Replace Lamp if defective (typical
Lamp life = 2,000 hours).
Power Supply Board
Failed
Check UV output voltage on Power
Supply Board. Set Oscilloscope to:
20ms/div 100V/div
Replace power supply board if
defective.
Igniter
Malfunctioned
Verify open circuit voltage from
Igniter. Set Oscilloscope to:
50us/div 1000V/div
Replace if defective.
EC Power
Supply Blows
Input Fuse
Malfunction in the
Power Supply Board
Remove power. Disconnect the
Lamp/Reflector Assembly from the
Power Supply. Replace the Fuse.
Apply power. If Fuse blows, Power
Supply is defective.
Replace the Power Supply Board.
UV Intensity
Appears To Be
Low
Lamp Beyond Its
Useful Life
Use a Radiometer to measure
actual output intensity. Consult
manual for proper output.
Replace Lamp if beyond useful life
(Typical Lamp life = 2,000 hours).
Quartz Envelope on
Lamp Contaminated
Visually inspect the Lamp for signs
of contamination (Quartz Envelope
MUST be free from ANY
contamination).
Clean the Lamp with a soft, lint-
free cloth and isopropyl alcohol.
Lamp may have to be replaced if
contamination is burned into
Quartz Envelope.
Surfaces Of Reflector
May Be
Contaminated
Examine Reflector for
contaminants (should be a clean,
shiny surface).
Clean Reflector with a soft, lint-
free cloth and isopropyl alcohol or
equivalent.
Glass Filter
Contaminated
(2000-EC Only)
Examine Glass Filter for signs of
contamination.
Clean Glass Filter with a soft, lint-
free cloth and isopropyl alcohol or
equivalent.
Reflector
temperature is too
low (5000-EC Flood
Lamps).
Verify Reflector temperature is
between 115° F and 145° F as
measured at the temperature
indicator on top of the Reflector
Housing.
Adjust Conveyor Temperature
Control Plates or add/remove
Reflector Ventilation Plates as
necessary to achieve proper
temperatures.
