4. Start-up procedure
The Electronic Ballast ARRI EB 1200/1800 Event Three consist of three 1800 W
modules (see fig. 3, page 17 ). Each module can operate one 1200 W or 18000 W
luminaire. All operating controls are arranged at the front panel. The connectors for
mains, lamps and remote control are placed on the rear panel of the EB (see fig. 2, page
16 ).
4.1 Energizing System
Check the ON/OFF Switches of all modules to be in "OFF"-position.
Connect up to three properly checked ARRI 1200 W Event or ARRI 1800 W Event
luminaires with a suitable ARRI Multicore System to the electronic ballast (see fig.
1, page 16 ).
In 1200 W luminaires (see Figure 1a, page 16) only 1200 W lamps may be used.
In 1800 W luminaires (see Figure 1b, page 16) both 1200 W and 1800 W lamps may
be used. The inserted lamp is detected electronically after starting the EB.
Connect the electronic ballast to the power supply source.
The three green LEDs "L1", "L2" and "L3" at the right side of the front plate are lit
when the according phase is supplied with line voltage ( >180V
eff
against neutral).
The red LED "MAINS FAULT" indicates that the ballast switched off due to line
overvoltage ( >270V
eff
against neutral). Possible cause may be the exchange of one
phase with the neutral wire.
The ballast will stay in this protection mode until it is disconnected from mains.
Check the line voltage before reconnecting the ballast to mains.
Check earth protection: If correct, the green LED "PE" on front plate illuminates. If
not, disconnect EB from mains (pull out line plug) and check power supply and
socket.
4.2 Operation of 1800 W Module
The LEDs "1200 W" and "1800 W" indicate the nominal power of the detected
luminaire resp. inserted lamp.
To switch a lamp on, set the corresponding ON/OFF switch to "ON"-position. The
LED "MODULE" goes on.
The nominal power of the connected luminaire resp. the inserted lamp is detected
electronically after starting the EB.
At the front panel of the module the “1200 W” resp. “1800 W” LED indicates the
current power mode. The EB always starts in 1200 W mode. In case of a 1800 W
luminaire the electronic lamp detection is activated for the first 3 minutes after
ignition. During this period, the corresponding Power LED is flashing and the
dimming function is disabled. After warming up the recognized nominal lamp power
is fixed, the corresponding Power LED lights up permanently and the dimming
function is enabled again.
In case of a 1200 W luminaire connected to the EB, the electronic ballast always
remains in 1200 W mode. The 1200 W LED flashes during warm-up period to
indicate that the dimming function is disabled.
The yellow LED "LAMP" of the regarding module is lit after successful ignition.
The red LED "TEMP" indicates that a module cuts off due to overtemperature. After
cooling down, the module 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 circuit breaker) for at least
1 minute.
