Connection to the mains supply

Before connecting the plasma cutting plant to the power
supply, check that the data on the plaque corresponds to
the power supply voltage and frequency and that the plant
line switch is in the "O" position.
This plant is designed for a nominal power supply of 230V
50/60 Hz.
Connection to the power supply must be effected using the plug
provided with the plasma cutting plant.
Table 2 lists the rating values for delayed line fuses chosen
on the basis of the nominal maximum power delivered by the
plasma cutting plant and the nominal power supply voltage.
Proceed as follows if you have to replace the plug:
• 2 conducting wires are needed for connecting the machine
to the supply
• The third, which is YELLOW GREEN in colour is used for
making the "EARTH" connection.
NOTE: If extensions of the power supply cable are used, they
must be of adequate cross section and never inferior to that of
the cable supplied.

LED Sequences

The following are the principal combinations or sequences
which the LEDs on the SHARK 25 rack panel may assume.
Important! Read this paragraph to fully understand correct plant
operation.

PAUSE
ON
The plant is functional but no cutting
operations are being executed at this
OFF
time.
OFF
EFFECTIVE WORKING
ON
The plant is functional and the operator is
ON
cutting at this time.
OFF
"TIME OUT" PILOT NOT TRANSFERRED
ON
Alarm! The pilot arc has not transferred
to the item to be cut. The LED flashes for
FAST INT
some 15 seconds.
OFF
THERMOSTAT CUT OUT
ON
Alarm! Protective thermostat triggered.
Wait for the yellow LED to go off, several
OFF
minutes, the recommence cutting.
ON
UNDER-VOLTAGE OR OVER-VOLTAGE
ON
Alarm! Incorrect power supply voltage.
Power off the plant and verify that line
LOW INT
power corresponds to the data on the
plaque.
OFF
AIR PRESSURE
ON
Alarm! Air pressure insufficient (<2.5 bar).
Power off the plant and verify that the air
LOW INT
compressor is functioning correctly.
OFF
"SAFETY" TORCH ACTIVE
ON
Alarm! External torch nozzle mounted
incorrectly. Power off the plant and verify
LOW INT
- remount the plasma torch correctly.

POWERING OFF
This sequence lasts a few seconds from the moment in which
the operator actions the machine power supply switch.
