4. Start-up procedure All operating controls are arranged on the front panel (see fig. 3, page 16 ).
The connectors for mains, lamps and remote control are placed on the rear panel of the
EB (see fig. 2, page 15 ).
4.1 Energizing System
l Check the ON/OFF Switches of all six 575 W modules to be in "OFF"-position.
l Connect up to six properly checked daylight luminaire with ARRI Multicore Cable
575-Six and ARRI Splitbox 575-Six to electronic ballast (see fig. 1, page 15 ).
l Connect the electronic ballast to the power supply source.
l 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 ( >90V
eff
against neutral).
l 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.
l 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 575W Module
l To switch a lamp on, set ON/OFF switch of the according module to "ON"-position.
The LED "MODULE ON" is lighting.
l The yellow LED "LAMP" on front plate is lit after successful ignition.
l The red LED "TEMP" indicates that the 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.
4.3 Control of light intensity
After warming up, the light intensity of the metal halide daylight-lamp may be controlled
by the dimming potentiometer (stepless). The nominal lamp power can be adjusted
between 50 - 105% (left stop = MIN, right stop = MAX of power).
