Protection - Broncolor HMI 575.800 Mode D'emploi

5.1 Daylight lamp
The daylight lamp used, operates at a high internal pressure and can explode if used
beyond its service life. The lamp should therefore be exchanged before it reaches the
maximum hours of indicated operation by the lamp manufacturer.
5.2 Protecting glass
The corresponding protecting glass must be used categorically to protect from lamp
explosion and UV-radiation. The lamp base HMI F575.800 is provided with a circuit
breaker. Therefore the unit cannot be switched on without a protecting glass. The UV-
coated protecting glass is also available in a matt version.
5.3 Exchanging lamp
Before replacing the lamp always disconnect the lamp base from the ballast unit!
Attention: Hot lamp !!!
After removing the protecting glass the counter reflector screws (6) must be loosened to
be able to remove the counter reflector over the lamp. Now the lamp can be replaced and
the counter reflector and the protecting glass can be remounted.

6. Protection

6.1 Fan cooling
A low-noised fan cools the lamp base.
6.2 Thermo-protection
If the ballast unit HMI 575.800 is in operation, the green LED „on" for the operation
control (5) must continuously light up. If the green LED flashes, the temperature control
is activated and regulates slowly the power down to 60%. If the ballast unit reaches the
predefined limit of overheating, the red LED "supply ok" of the mains control (6) starts to
flash and the ballast unit switches off automatically.
For safety reasons the unit does not switch on automatically when the technical failure is
resolved and it has returned to the normal operation mode (red LED lights up
continuously). The lamp must be switched on again manually.
The lamp base HMI F575.800 is also equipped with a thermo-protection and switches off
automatically if overheating. In this case the lamp base must be switched off manually,
with the mains switch (1), to avoid, that it automatically switches on again after the
cooling process.
