Intermediate distributor
The following supply voltages and signals are routed by
the intermediate distributor to the individual placement
head modules or to the head board:
1. LEDs show the operating voltages on the head and
the sensor states
▪ Connector X1, 40-pole: connected to connector X1
on the head adapter board
▪ Connector X2, 40-pole: connected to connector X2
on the head adapter board
▪ Connector X3: connection for the star motor
▪ Connector X4: connection for the star incremental en
