4.3.4 Options
The options described below are an integral part of the standard equipment of the LNS bar
feed systems.
These signals, however, are not required for the proper operation of the devices, or the safety
locking for protecting persons and materials. The options are available only to optimize
production conditions.
a) R5 Auxiliary end of bar relay
This signal may be used to reduce the length of the remnant in case the remnants exceed the
maximum admissible length for the parts catcher of the lathe or its chip conveyor. Relay R5
energizes as soon as the feeding pusher reaches the programmed position.
4.3.5 Recapitulation of safety instructions related to the interface
C The lathe foot switch for opening the lathe clamping device should not be operational
during the automatic cycle of the lathe.
• The lathe pedal should not be operational as long as the feeding pusher feed command
signal is present.
• Whenever possible, it is advisable to interlock lock the manual command for opening
the lathe clamping device while the feeding pusher command signal is on.
• If the lathe is in the Emergency Stop mode, the bar feed system must also be under the
Emergency Stop mode, and vice-versa.
• If the bar feed system generates an alarm, the lathe should go into alarm mode. The
feeding pusher feed command signal should go off, the spindle axis and rotation
should must stop.
