ONLY QUALIFIED MAINTENANCE PERSONNEL SHOULD ATTEMPT THE
Possible Cause
Improper connections
Lamp beyond useful life
Corroded negative electrode
(brass bracket)
Main line fuse blown (nothing in
unit operates)
No high voltage off transformer
output
Insufficient ignition voltage
No operating voltage (lamp
flickers)
Possible Cause
Shutter mechanism binding
Solenoid malfunctioned
Timer malfunctioned
TM-023 PN 37099
Rev 05/12/98
WARNING
FOLLOWING PROCEDURES:
Problem: Lamp Will Not Ignite
Testing
Visually inspect all input/output
connections (i.e. power cord, lamp).
Replace with a known good
lamp/reflector assembly and re-test unit.
Visually inspect the negative electrode
for ANY signs of corrosion.
Remove fuse from power receptacle
and check with an ohmmeter.
Verify ignition voltage of 1200 Vrms off
transformer.
Verify ignition voltage across open
circuit (should be half rectified
shortwave of 1200 Vrms).
Verify the operating voltage of 20 Vac
across bulb with dummy load.
Problem: Shutter Fails To Open
Other Symptoms: Shutter Remains Open
Testing
Remove power from unit and manually
move the shutter and solenoid up and
down (should move freely).
Measure the voltage being delivered to
the solenoid during operation. If good
check solenoid resistance (120 ohms).
If shutter operates in manual mode but
not in timed mode, timer is defective.
TROUBLESHOOTING
Corrective Action
Secure all connections.
Replace lamp/reflector assembly if
defective (typical life = 500 hours).
Replace, if corroded.
Replace fuse, if defective.
Replace transformer, if defective.
Replace defective component
(typically blocking diode).
Replace defective component.
Corrective Action
Replace component causing
problem.
Replace solenoid, if defective.
Replace defective timer.
