4.7.2.1 EMERGENCY STOP
4 emergency channels are available, 2 from bar feeder towards to lathe and 2 from lathe to bar
feeder.
· Emergency signal from bar feeder to lathe (2 channels, open contacts=Emergency
activated).
It is used to transmit the active emergency 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 (bar feeder/lathe) is stopped.
· Emergency signal from lathe to bar feeder (2 channles, open contacts =
Emergency activated).
It is used to transmit the active emergency from the lathe to the bar feeder.
As soon as the bar feeder receives these signals, an emergency stop (safety class 3 compliant)
is activated.
4.7.2.2 COVER SAFETY STOP (WHEN PROVIDED)
4 cover safety channels are available, 2 from bar feeder to lathe and 2 from lathe fo bar feeder.
· Cover safety signal from bar feeder to lathe (2 channels, open contacts= open
covers).
Whenever the above mentioned signals are closed, the bar feeder informs the lahte that the
covers are closed: all lathe operations as well as indexing are now allowed.
Whenever one of bar feeder covers is open, the signals are stopped: in this case, all dangerous
operations on the lathe (i.e., on multispindle machines, spindle drum indexing) must be stopped
immediately ,in agreement with safety class 3.
As soon as the contacts are closed, the lathe operation can be recovered.
· Cover safety signal from lathe to bar feeder (2 channles, open contacts= open
covers).
Whenever the above mentioned signals are closed, the lathe informs the bar feeder that the
covers are closed: the bar pusher can be pushed forward.
As soon as one the covers on the lathe is open, the bar pusher is stopped immediately, in
agreement with safety class 3, to avoid injury to the operator.
Any jumper on the safety signals, which had been set for bar feeder final test, should be
removed in order to restore the safety signals.
ATTENTION-DANGER !!!
Bar feeder safety depends on these connections, therefore IEMCA is not responsible for any
enventual damage to persons or structures, caused by improper use of the above mentioned
signals.
