4. ELECTRICAL CONNECTIONS
Before connecting, check to make sure that the voltage of the bar feeder corresponds
to the one provided by the lathe. The voltage of the bar feeder is indicated on the
identification plate.
Voltage: 3 x 220-480 V, 50 / 60 Hz + Ground (± 10%)
Maximum current: 3 x 220 V = 6 A
3 x 480 V = 3 A
In the case where the voltage supplied by the lathe does not match that provided for the bar feeder, the
following must be adapted:
a) Transformer T1
b) Hydraulic pump motor
The LNS bar feeders are equipped with their own thermal protection systems (breakers, thermal relays
and fuses, etc.). The power supply for the bar feeder should be connected to the output of a breaker
mounted in the electrical control box of the lathe (10 A max.).
For the wiring inside the lathe, the section of the cables should be at least 1.5 mm
2
(AWG 16).
4.1. Electrical interface lathe – barfeed
Always refer to the electrical diagrams shipped with the bar feeder and placed in the electrical cabinet.
Although an example of an interface diagram is provided, the diagram for the interface corresponding to
your device, essential when making the electrical connection, is located inside the electrical cabinet.
Only LNS (or certified technician) is authorized to modify the interface or parameter
system.
