5.2. OPERATION WITH CAPACITOR FOR POWER FACTOR CORRECTION:
The EFS STARLIGHT- KIT is also suitable for magnetic ballast including front end serial capacitor (leading
ballast) or parallel shunt capacitor. Nevertheless with front end serial capacitor, only one ignition attempt
will be performed. After this first attemp, the serial capacitor superimposes a -300V DC voltage on the
mains voltage. This offset masks the starter which detects the tube lamp as systematicaly alight.
With a front end parallel capacitor, the ignition process remains normal with 8 attempts in case of defective
lamps.

5.3. OPERATION ON 230V/50HzAC MAINS IN TWIN TUBES CONFIGURATION OR 115V/50Hz MAINS
IN SIGNLE LAMP CONFIGURATION
Moreover, the EFS STARLIGHT-KIT is also suitable for the configurations - Twin tubes Starter / 230V /
50Hz, and Single Starter / 115V / 50Hz -.
The components to choose are the following
(Refer to the table ”EFS STARLIGHT- KIT PARTS
SELECTION” page 2.)
With the above set of components, the ignition process is exactly the same as the one described in the
algorithm page 7.
The only electrical diagram difference consists of the R2 resistance which needs to be changed from 1 to
2k
. Without this modification, the starter will generate only one ignition attempt instead of 8 in case of
defective tube lamp; the loop 3 is removed from the algorithm described in page 7.
