automatic placement systems have 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 item 14 and 15 in Fig. 1.2.4).
DANGER
Automatic placement systems from the SIPLACE family are powered with 3x400VAC ± 10%, 50/60Hz mains
voltage.
This means that parts of the system carry potentially fatal voltages - even when switched off at the main switch.
Death, serious injury or considerable damage may result if these automatic placement systems are handled
incorrectly.
Always follow the applicable accident prevention and DIN regulations (particularly DIN 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.
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 transformer 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.

1.2.5 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
conveyors available, a guard ("feeder dummy") must be fitted in place of the conveyor.
The following variants can be used:
Item no. 00116820-01SIPLACE guard for 1 location
Item no. 00116821-01SIPLACE guard for 6-10 locations
Item no. 00116822-01SIPLACE guard for 11-20 locations
