Emergency stop
The arrangement of the emergency stop controls permits an easy access and a
safe operation. In situations of danger, one of the emergency stop controls is to
be activated immediately.
Function
Note
Emergency stop
Emergency stop switches, pull wire, key-operated
switches, safety doors, safety photocells etc.
The emergency shutdown has priority over all other commands. As soon as one
of the emergency stop controls is activated, all motion sequences of the ma-
chine/system are stopped. Some of the pneumatic drive units only stop when
they have reached the final position. The data required for the motion sequences
of the machine/system are stored by the programmable logic control (named
PLC in the following chapters).
In case of an emergency shutdown, the machine/system remains energised. In
order to de-energise the machine/system, disconnect the main switch.
Danger!
In case of an emergency shutdown, the film brake and the film roll drive
still remain functional.
Do not reach into the area between film brake and idler!
The "Reset emergency stop" illuminated pushbutton in the control cabi-
net/control terminal of the machine/system indicates the different states.
