K1 or K2 is triggered if any of these functions fail. The mains voltage to the heavy current trans-
former that supplies the gantry axis motors will be interrupted. The voltage to the star-type motor
for the Collect&Place head is reduced from 70 V to 10 V. The DP and DR axes of the placement
heads continue to be supplied with 30 V. The next diagram illustrates the various statuses of K1
and K2 and their effects on the axes and the PCB conveyor components.

2.5.5 Guard on the component table locations
WARNING 2
All locations must be equipped with feeders in order to guarantee operational reliability. If there
are not enough feeders available, a guard ("dummy feeder") must be fitted in place of the feeder.2
