SERVICE MANUAL – QL Servo S3-T

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.

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.

R6 bar stock magazine empty relay

Contact of relay R6 (optional). Relay R6 engages after verification of the presence of a bar during the loading cycle of a new

bar.

RECAPITULATION OF SAFETY INSTRUCTIONS RELATED TO THE INTERFACE

•

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 must go into alarm mode. The feeding pusher feed command

signal must go off, the spindle axis and rotation must stop.
