on). Adjust the pressure to the range
required for the torch during this phase.

2 - Displaying the digital pressure gauge air pressure.
- Press the air button to expel air from the torch (
on).
Set the required pressure value using the pressure reducer knob
(Fig. E-3).
- Pull upwards to release and turn it (Fig. E-3).
A warning will appeal if the set pressure is out of the required
range (Fig. D-3).
- On completing the adjustment, push the knob downwards to
block adjustment (Fig. E-3).
3 - Alarm codes, warning with power block (TAB. 3).
Resetting of an alarm or warning condition normally occurs 10
seconds after the case that generated the same has been eliminated.
01: Primary circuit thermal protection switch has been triggered.
02: Secondary circuit thermal protection switch has been triggered.
03: Power supply line overvoltage protection has been triggered.
04: Power supply line undervoltage protection has been triggered.
05: Magnetic components thermal protection switch has been
triggered.
06: Power supply line phase failure has been triggered.
08: Auxiliary voltage out of range.
09: Air circuit pressure switch has been triggered.
15: Torch safety circuit has been triggered.
Warning codes, warning without power block:
07: Excessive dust inside the machine warning
11: Torch / Consumables wear warning.
14: Serial data error warning.
16: Air circuit pressure outside optimal interval warning.
17: Power line instability warning.
4 - Alarm or warning present.
5 - Powered machine output.
When on, this indicates a powered machine output: cutting circuit
enabled (Pilot arc or Cutting arc enabled).
Output is powered when the torch button is pressed and there is no
alarm status.
The machine output is not powered in the following cases:
- when the torch button is NOT being pressed (standby status).
- in CUTTING, CUTTING BLOCKED and GOUGING modes during the
post gas (10 seconds).
- in any alarm status.
The machine disables the output in the following cases:
- in CUTTING, GRID CUTTING and GOUGING modes on releasing the
torch button.
- in CUTTING BLOCKED mode on releasing the torch button during
the pilot arc or on pressing the torch button during the cutting arc.
- if the pilot arc is not transferred to the piece within a maximum of
2 seconds (4 seconds in GOUGING mode).
- in CUTTING, CUTTING BLOCKED and GOUGING modes if the
cutting arc is interrupted because the torch is too far from the
piece, if the electrode is worn out or if the torch is deliberately
taken away from the piece (in GRID CUTTING mode the arc is
always maintained).
- in GRID CUTTING mode if, on completing a cutting cycle, the next
cycle does not commence within 10 seconds.
- if an alarm is triggered.
6 - Thermostatic safeguard.
7 - No air.
8 - Damaged consumables.
The causes of a faulty consumable warning can be:
- worn consumables.
- consumables mounted incorrectly.
- faulty torch.
- excessively low air pressure.
This warning is reset after a correct cutting cycle.
9 - Analogue pressure gauge.
10 - Remote control present.
This comes on when one of the following remote signals on the rear
connector is inserted (Fig. E-3):
1- A serial MODBUS type connection.
2- An external power enabling command.
3- A signal to set a current higher or equal to 1V.

PIN 1 Polarizer
PIN 2.3 MODBUS Rs485.
PIN 4.5 Cutting arc contact. Normally open, it closes when the
cutting arc is enabled.
PIN 6.7 Pilot arc contact. Normally open, it closes when the pilot arc
is enabled.
PIN 8 External power enabling command. If closed at 0[V] (PIN12) it
will enable power. It completely replaces the torch button function.
PIN 9 Voltage OUT signal. Range 0-10[V] with settable range
10V/200V, 10V/300V, 10V/400V, 10V/500V. The setting requires
simultaneous pressing of the “Encoder and Select Mode” buttons
when the card is booted. Select the desired range using the encoder.
Press the “select mode” button again to exit.

5. INSTALLATION
ATTENTION! CARRY OUT ALL INSTALLATION AND
ELECTRICAL CONNECTION OPERATIONS WITH THE PLASMA CUTTING
MACHINE RIGOROUSLY SWITCHED OFF AND DISCONNECTED FROM
THE MAINS.
THE ELECTRICAL CONNECTIONS MUST ONLY BE CARRIED OUT BY
EXPERT OR QUALIFIED TECHNICIANS.
Assembling the clamp-return mass cable (Fig. G)
POSITIONING THE MACHINE
The machine must be installed in a place where there are no obstructions
to the cooling air input and output apertures; at the same time, make
sure that there is no possibility of conductive powder, corrosive vapour or
moisture etc. being sucked into the machine.
Allow at least 250 mm of free space all around the machine.
