2 -- PREDISPOSITION FOR INVERTER (OPTIONAL)
Selects the blade cutting speed range: from 20 to 45 mt/min. (from 6.23 to 14.02
in.) for the 1st speed and from 35 to 90 mt/min. (from 10.90 to 28.04 ft./min) for
the second speed.
This model has been designed for the installation of a frequency converter
(inverter) and is set up for both the electrical wiring and converter control
potentiometer, which must be housed in the machine control panel.
3 -- AUTOMATIC THERMAL--MAGNET CUTOUT WITH MINIMUM VOLTAGE RE-
LAY AND HATCH LOCKING DEVICE
The machine is provided on the right of the control panel with a main switch with
a locking device which, when set in the ON position (1), powers up the machine
by resetting the minimum---voltage relay and the blade motor thermal magnet
cutout.
This device has three protection systems against power failure. When there is a
power failure the electrical devices are all shut down, instantly shutting down the
machine and preventing automatic restoring of power on power return. A further
function is to reset the thermal relay, which protects against overcurrents.
4 -- POLARITY CHANGE SWITCH
This selects the blade cutting speed, 36/72 mt/min. (from 11.21 to 22.43 ft./min)
on the standard 2---speed machine.
5 -- EMERGENCY STOP MUSHROOM BUTTON
Pressing this button immediately stops machine operation. The emergency
button, designed to conform to all safety standards, is positioned so that it is
easily accessible at any time and is clearly visible --- being a red button on a yellow
background.
To reset the emergency button, rotate actuator by 45˚.
OPTIONAL PEDAL FOR VERSION WITH AUTOMATIC VICE (MA)
