4.8.2.1 EMERGENCY STOP
4 emergency channels are available, 2 from bar feeder to lathe and 2 from lathe to bar feeder.
· Emergency from bar feeder to lathe (2 channels, contacts on = Emergency
activated).
It allows transmitting the active emergency state from the bar feeder to the lathe.
These signals should be integrated with the lathe emergency signals, so that in case of an
emergency stop, the whole unit (lathe/bar feeder) is stopped.
· Emergency signal from lathe to bar feeder (2 channels, contacts on = Emergency
activated).
It allows transmitting the active emergency state from the lathe to the bar feeder.
As soon as the bar feeder receives these signals, an emergency stop (safety class 3) is
activated.
4.8.2.2 GUARD SAFETY STOP (IF PROVIDED)
4 guard safety channels are available, 2 from bar feeder to lathe and 2 from lathe to bar
feeder.
· Guard safety signal from the lathe to the robot (2 channels, contacts on = open
guards).
Whenever the above mentioned channels are closed, the bar feeder informs the lathe that the
guards are closed: all lathe operations, displacement included, are now allowed.
Whenever one of the bar feeder guards is open, these signals are stopped: in this case, the
lathe immediately stops (safety class 3) all the movements that may harm the operator (e.g. in
the multispindle, the spindle drum displacement).
As soon as the contacts are closed, the lathe will start operation again.
· Guard safety signal from lathe to bar feeder (2 channels, contacts on = open
guards).
Whenever the above mentioned signals are closed, the lathe informs the bar feeder that the
guards are closed: the bar feeder can move the bar pusher forwards.
As soon as one of the guards on the lathe is open, the bar pusher is stopped immediately, in
agreement with safety class 3, to avoid injury to the operator.
Some jumpers may be fitted on the safety signals for testing purpose only. Therefore, they
should be removed in order to restore the safety devices.
DANGER-WARNING !!!
The bar feeder safety depends on these connections, therefore IEMCA is not responsible for any
possible damage to persons or things, caused by improper use of the above mentioned signals.
