2.2.3.1 Functional description

EMERGENCY STOP mushroom-head push-button 2

When the emergency stop mushroom-head push-button is pressed (item 3 or item 4. in

Fig. 2.2 - 4), the motor voltage to the gantry axes is switched off. The gantry axes are no longer

powered, and thus are not dangerous. 2

PLEASE NOTE

Placement is interrupted and can then either be continued or cancelled once the system is working

correctly again. 2

Protective cover switch 2

If one of the protective covers is opened (see item 9, 10, 11 or 12 in Fig. 2.2 - 4), the gantry axes

will stop immediately. They are no longer powered, and thus are not dangerous. 2

Key switch 2

If the key switch (item 8 in Fig. 2.2 - 4) is closed (position I), the star can still be paced at low speed

while the protective covers are open. The gantry axes are no longer powered, and thus are not

dangerous. 2

PLEASE NOTE

The key switch remains open for normal mode, i.e. in the 0 position. 2

WARNING

The protective covers must only be opened, with the key switch closed (position I), by appropri-

ately qualified and trained personnel. 2

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) ± 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 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

2.2 Safety equipment Software Version SR.405.xx 05/99 Issue

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.
