3. Product Description
The ARRI EB 400/575 D is part of an optimized lighting system along with all ARRI
400 W and 575 W luminaires specified for operation with the EB (see fig.1 , page 13).
It is suitable for both professional indoor and outdoor use (IP 22 protection).
The Electronic Ballast EB 400/575 D meets the European Council Directive
89/336/EEC of electromagnetic compatibility. The limits of EN 50081-1 are fulfilled.
Compared to magnetic ballasts there are a number of advantages when operating
daylight-lamps with ARRI Electronic Ballasts:
•
Flicker free light
•
No synchronization of cameras necessary
•
Typical lightripple max. 3 %
•
Light intensity increased by at least 5 %
•
Constant lamp power
•
Constant color temperature
•
Constant light quality
•
Control of electric power of the lamp between 50...100% of nominal lamp power.
•
Variation in power supply voltage of 10% has no influence on the power of the
lamp (see also "Technical Data" for limits, on page 11).
•
Variation in power supply frequency of 10% has no influence on the power of the
lamp
•
Operating life time of the lamp increased by at least 20%
•
Substantially less volume and weight compared to magnetic ballasts
•
The ballast is built-in to a casing with type of protection IP 22.
4. Start-up procedure
All operating controls and cable connections are arranged on the front panel
(see fig. 2, page 14).
4.1 Energizing System
•
Check mains switch to be in "O"-position.
•
Connect the properly checked daylight luminaire with head to ballast cable to the
corresponding connector of the electronic ballast
•
Connect the electronic ballast to the power supply source.
•
Set mains switch to "I"-position. The green LED "POWER" is lit, when the ballasts
is supplied with line voltage.
If lamp does not strike check if the switch at the lamp head is switched on.
•
Check earth protection. If correct, the green LED "PE" illuminates when the ballast
is switched on.. If not, disconnect EB from mains (pull out line plug) and check
power supply and socket.
•
The white LED "LAMP" on front plate is lit after successful ignition.
•
The red LED "TEMP" indicates that the ballast cuts off due to overtemperature.
After cooling down, the ballast restrikes the lamp automatically. The LED "TEMP"
stays lit to indicate a temperature problem. To reset the LED the ballast must be
disconnected from mains (pull out line plug or switch off mains switch) for at least
15 seconds.
•
The LED "REMOTE" is designated for ballasts with remote control and has no
function with this model.
