In these cases the SIPLACE and the SWS EMERGENCY STOP circuits are interrupted and the

corresponding EMERGENCY STOP switching devices switch the contactors off (delayed by 500

ms). Thus, there is a remaining time for a controlled stop function:

– The 48 V link voltage for the servo motors is switched off.

– The operating status indicator (white) on the SWS is switched off.

– The compressed air main valve Y1/PRS for the die ejector lift is switched off.

– The compressed air valves of the cylinders for tool Z (pickup) and tool X (die attach unit) are

switched off.

– The drives are switched off and the tools are held in a secure position by means of spring

elasticity.

– The braking magnet for the magazine lift function is switched off. The brake is active and the

magazine lift is held in position.

Resetting the EMERGENCY STOP

To reset an EMERGENCY STOP the EMERGENCY STOP circuits of the SIPLACE and the SWS

must be closed again.

– Release the pressed EMERGENCY STOP button on the SWS or the placement machine.

– Close any opened protective covers on the placement machine.

 Switch the SWSs and the placement machine on.

The modules are starting up. As long as the placement machine is not yet switched on, an

error message will be displayed on the screen of the SWS module, which points out that the

safety circuit is not closed.

As soon as the placement machine has started up, the start circuit is closed (by means of out-

put 1 = K4 (on/off 150 ms). The error message regarding the not-closed safety circuit van-

ishes from the SWSs. Initialize the SWS module.

2.8.5 Hand Guard at the Component Trolley Locations, SIPLACE X-Series

WARNING 2

Component trolleys from the SIPLACE X-series are guaranteed to be safe to use if at least every

other free location is filled with a feeder module or a hand guard (dummy feeder). When a waffle-

pack holder is set up, every other free locations should again be protected again with a hand

guard. In other words, there must be no more than one free location between two adjacent

feeder modules or feeder module and waffle-pack tray holder.

The hand guard uses an 8 mm location and can be changed during placement progress.

2.9 Residual Voltages and Discharge Times

2.9.1 (Placement) Machine

If the EMERGENCY STOP button is pressed or the placement system is switched off, the 250

VDC link voltage for the gantry axes and the 145 VDC link voltage for the star axes are reduced

to harmless residual voltages in a very short time.

WARNING 2

The placement system is supplied with 3 x 208 V~, 3 x 230 V~, 3 x 380 V~, 3 x 400 V~ or

3 x 415 V~ ± 5 %, 50/60 Hz mains voltage. This means that some parts of the system carry

potentially lethal voltages - even when switched off at the main power switch. Incorrect handling

of the placement system can therefore result in death or severe injury or considerable damage to

equipment.

 Always follow the applicable accident prevention and DIN regulations (particularly DIN EN 60

204, part 1).

 The guards over the power supply unit and the axis unit must ONLY be opened by appropri-

ately qualified and trained personnel.
