Protective contactor combinations K1 and K2 monitor the following circuits:
K1: Emergency stop circuit, safety circuits for the component tables or wafflepack changer,
protective cover switch and the enable software signal
K2: Emergency stop circuit, K1 protective contactor combination, software enable signal and
key switch
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 revolver head is reduced from 70V to 10V. The dp and dR axes of the placement heads
continue to be supplied with 30V. The next diagram illustrates the various statuses of K1 and K2
and their effects on the axes and the PCB conveyor components.

2.2.5 Guard on the component table locations
DANGER
All locations must be equipped with feeders in order to guarantee operational reliability. If there
are not enough feeders available, a guard ("feeder dummy") must be fitted in place of the feeder.
The following variants can be used:
Item no. 00116820-01 SIPLACE guard for 1 location
Item no. 00116821-01 SIPLACE guard for 6-10 locations
Item no. 00116822-01 SIPLACE guard for 11-20 locations 2
