2.2.3.2 Status messages and the action required
The following displays may appear in placement mode. If they appear, carry out the action spec-
ified in the third column. 2
2.2.4 Safety circuits
The SIPLACE S-23 HM automatic placement system has two separate safety circuits which are
monitored by protective contactor combinations K1 and K2. Both protective contactor combina-
tions are incorporated into the power supply (see item 14 and 15 in Fig. 2.2 - 4). 2
DANGER
Automatic placement systems from the SIPLACE family are powered with 3x400VAC (3 x 208
VAC U.S.A. version) ± 5 %, 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 place-
ment 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 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.
