2.5.4 Safety circuits
The SIPLACE automatic placement system has two separate safety circuits which are monitored
by protective contactor combinations K1 and K2. Both protective contactor combinations are
incorporated into the power supply (see items 14 and 15 in Fig. 2.5 - 4
).
WARNING
Automatic placement systems from the SIPLACE family are powered with 3 x 400 VAC (3 x 208
VAC for the U.S.A. version) ± 5 %, 50/60 Hz main power voltage.
This means that some parts of the system carry potentially lethal voltages - even when switched
off at the main power switch. Death, serious injury or considerable damage may result if these au-
tomatic placement systems are handled incorrectly.
Always follow the applicable accident prevention and DIN regulations (particularly EN 60204,
part 1) and the applicable regulations in your own country.
The guard over the power supply must ONLY be opened by appropriately qualified and trained
personnel. 2
Protective contactor combinations K1 and K2 monitor the following circuits:
K1: EMERGENCY STOP circuit, safety circuits for the component trolleys or waffle-pack
changer, protective cover switches 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 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.
