15) TROUBLE SHOOTING
A.
If the red indicator in the mains switch doesn’t illuminate, the mains outlet or
mains cable may be defective.
B.
If the mains switch can’t be switched on:
- mains voltage above 264 V
- mains voltage has voltage spikes
- short circuit in the ballast.
C.
If the “READy” control indicator on the ballast and on the light head doesn’t light
up, this indicates an interuption of the safety loop.
Possible causes:
- lock rings of cable connectors are not properly closed
- the lighthead door is not closed.
D.
If the red “HEAT” control indicator lights up, this shows overheating in the
ballast ( >85°/185° F).
Possible causes:
- ambient temperature too high
- ballast exposed to direct sunlight
- air intake and/or outlet slit openings on ballast are obstructed
- fan failed or is obstructed by foreign object.
- Solution: Eliminate cause and reactivate ballast after cool down period.
E.
When pushing the start key and „Lamp“ control indicator and „Ready“ control
indicator beginns blinking yellow switch equipment OFF and separate it from mains.
Possible causes:
-no lamp installed.
-lamp not seated deep enough in socket
-lamp defective
-ignition, cable, ignitor or socket defective
F
. Ballast switches off after a few minutes of light head operation.
Possible causes:
- lamp is at end of lifetime
- lamp damaged (i.e. cracks in the glass, blackened envelope, dirty or oxidized contact).
- ambient temperature of ballast is too high
- input voltage fluctuations exceed specified limits
G.
If light head cable shows sharp bends or damage, broken leads could be the
cause of malfunction.
In case of component failure: If none of the above mentioned faults can be
detected, the entire system should be sent for repair.
