2.5.2.3 Position of protective switch on the machine
Unexpected starting of the machine is protected by the protective switch on the front protective
hood.

Protective cover switch
(see 2.5.2.3 "Position of protective switch on the machine" [}37])
This switch check whether the protective hood is closed. When it‘s closed, the safety interlock mod-
ule is closed. The protective hood cannot be opened (it is locked) unless the user actively presses
the software button "Open front door" from the ASM SPI GUI inspection software. If the cover is
opened, the safety interlock module will open. Individual components are disabled or remain en-
abled.

2.5.3 EMERGENCY STOP loops and signaling circuit
2.5.3.1 EMERGENCY STOP loop structure
The following contacts are connected in series and form the EMERGENCY STOP loop:
●
Make contact elements for the protective cover switch
●
Make contact elements for the EMERGENCY STOP button
All the signaling contacts are closed when the machine is on standby. If a protective cover, for
example, is raised, the associated signaling contact opens and the safety interlock module re-
leased.
2.5.3.2 Description of the functions of the EMERGENCY STOP loops
The following conditions must be fulfilled in order to start and operate the machine:
●
The protective hood must be closed.
●
The emergency stop button must be released.
The machine is then ready for use.
2.6 Residual voltages and discharge times in the machine
2.6.1 Energy state of the machine after the EMERGENCY STOP button is pressed
If the EMERGENCY STOP button is pressed, the voltage are reduced to harmless residual
voltages in a very short time.
WARNING
Some parts of the system carry potentially lethal voltages
The machine is supplied with 1/N/PE ~ 240, 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 machine can therefore result in death or severe in-
jury or considerable damage to equipment.
► Always follow the applicable accident prevention and safety regulations (particularly
DIN EN 60204, part 1 or IEC 60204, part 1) and the safety regulations in your own
country.
► The covers over the power supply unit may ONLY be opened by appropriately quali-
fied and trained personnel.
