The only electrical diagram difference consists of the R4 resistor which needs to be changed from 1 to
2.2kΩ. Without this modification, the starter will generate only one ignition attempt instead of 8 in case of
defective lamp; the loop 3 is removed from the algorithm described in page 9.

In the Twin Series 230V/50Hz configuration, the polarity of the two starters must be respected:
In case of no operation of starters, rotate one of the starters of 180° on its socket.
