LICHTTECHNIK
Constant color temperature
Constant light quality
Control of electric power of the lamp between 50...100%
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 lifetime of the lamp increased by at least 20%
Substantially less volume and weight compared to magnetic ballasts
4. Start-up procedure
All control functions to the EB are given by the Control Unit. The remote control
connector is placed on the back plate of the EB together with lamp and line connector.
4.1 Energizing System
The EB 4000 Booster must be placed in a suitable 19" Cabinet Rack or housing.
The ballast must be ventilated sufficiently. The appearing heat loss in 4 kW
operation is about 450 W per ballast.
Connect properly checked daylight luminaire to the ballast.
Connect the remote control to the ballast.
Connect the electronic ballast to the power supply source.
Set main circuit breaker to "On" position
Use remote control to switch on the ballast.
Ballast starts and LED "Ballast on" is lit.
Lamp will ignite after about 3 sec.
The yellow LED "LAMP" on front plate is lit after successful ignition.
4.2 Control of light intensity
After warming up, the light intensity of the metal halide daylight-lamp may be controlled
by the remote control. The lamp power can be adjusted between 50 - 100% of nominal
lamp power.
4.3 Boost Operation
The EB can be set to boost operation by use of the remote control (see fig.2, page 13).
While boost mode is active the lamp power is increased to twice the dimming value
adjusted at remote control.
The boost time must be limited to max. 20 sec. by the remote control. Exceeding this
time limit can cause damage to the lamp, lamphead and electronic ballast.
After ignition of lamp and after every boost cycle there must be a boost inhibit time of at
least 180 sec. After this time a new boost cycle can be started.
