Position switch location 1 and 2 (item 1 and 4 in fig. 2.5 - 4, page 84) 2
This position switch checks whether the protective covers are open or closed. The position
switches on the protective covers trigger the safety cutoff (lock) when a protective cover is
opened. Individual components are disabled or remain enabled (see fig. 2.5 - 6
, page 90 ). The
protective covers are mechanically locked during placement machine operation. The protective
covers can only be opened once the stop button has been pressed.
Protective cover switch for COT insert location 1 and 2 (item 2 and 3 in fig. 2.5 - 4, page 84) 2
This position switch checks whether the component trolley is docked onto the COT insert. The po-
sition switch on the COT insert triggers safety cutoff (lock) when one of the component trolleys is
undocked.

Safety cutoff (CSB) (item 1 in fig. 2.5 - 5, page 87) 2
The safety cutoff (CSB) is located in the power supply unit. It is used to monitor the protective fea-
tures and checks for hazardous voltages or movements.
2
There are three conditions that must be fulfilled in order to activate the safety cutoff (CBS):
– All protective features and the EMERGENCY STOP buttons must be released.
– The start button must have been pressed.
– The "software release" or "Control ON" signal must be issued by the control software.
Service socket (only installed up to machine number TB070G) 2
The service socket is only installed in the SIPLACE TX up to machine number TB070G.

DANGER
Lethal voltages under the safety cutoff (CSB) cover!
Under the cover there are components which could still carry lethal voltages, even when
the placement machine is switched off and the mains plug has been disconnected. After
disconnecting the mains plug, wait 5 minutes until the capacitors have discharged.
Never open the covers.
Only ASM Assembly Systems GmbH&Co.KG service engineers or the machine
owner's service engineers, who have been trained by ASM, may perform work on the
power supply and the safety cutoff (CBS).
PLEASE NOTE
– The service socket can only be used in networks with a neutral conductor present
and connected.
– The service socket may only be used by trained service personnel.
– It is only to be used for the connection of service equipment which has the relevant
voltage range and for plugs which fit the service socket.
– The available voltage between L and N depends on the mains voltage supply at the
installation site.
– Please observe the applicable local regulations! If the service socket installed does
not comply with the applicable local regulations, it may not be used and must be
completely disabled!

2.5.3.1 Overview of safety cutoff
When the placement machine is ready for operation, the contacts of all position switches and the
EMERGENCY STOP buttons are closed. If a protective cover, for example, is raised, the corre-
sponding switch and safety cutoff will be triggered. For the operator's information, this status
change is signaled to the control computer via a digital CAN bus input signal from the I/O control
unit. An error message to this effect appears on the user interface.
Prerequisites 2
The following conditions must be fulfilled in order to start and operate the placement machine:
– All component trolleys must be docked into place.
– All protective covers on the placement machine must be closed.
– The two emergency STOP buttons must be released.
– The minimum operating pressure must have been reached.
– The software release ("Control ON") must be enabled.
If one of the start buttons is now pressed, the safety cutoff (CBS) will switch the safety-controlled
supply voltages on and the placement machine will be ready for operation.
Safety cutoff components 2
The following components are monitored by the safety cutoff:
– Position switch for the four protective covers on the placement machine
– Two EMERGENCY STOP buttons on the placement machine
– Position switch for the COT inserts on the placement machine
