30 CHAPTER 3: SETTING INTO OPERATION
MOVE S2
The options described below are an integral part of the standard equipment of the LNS bar feeders.
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.
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.
Contact of relay R10 (optional). Relay R10 engages after verification of the presence of a bar during the
loading cycle of a new bar.
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 feeder must also be under the Emergency
Stop mode, and vice-versa.
If the bar feeder generates an alarm, the lathe must go into alarm mode. The feeding pusher feed
command signal must go off, the spindle axis and rotation must stop.
