Switching on and operating the machine
Attention
–
Damage to machine!
-
The machine can become damaged if you attempt to move the stand-alone unit by
pulling on one of the cables. Always ensure that there is no nominal tensile stress
on the cables.
The cable assembly can also be damaged by kinking or bending it too tightly. Do
not kink the cable assembly (incl. HV cable) and adhere to the minimum permitted
bending radius in accordance with
the “Technical Data” chapter (page
-
A ceramic component is built into the plasma generator. This can become
damaged in the event of hard impacts or falls, and can in turn damage the
machine. Always ensure that the plasma generator is secured against impacts and
falls during transport.
-
The plasma generator may be damaged if it is started without gas. Never switch on
the plasma generator before the gas stream (2 seconds) is switched on.
-
When switching off the plasma generator via the “Plasma ON/OFF” button, the gas
supply must continue for at least 2 seconds. During this follow-on time, never
switch off the machine at the master switch and do not disconnect the power
supply. This could cause damage to the machine.
The machine can be operated as a stand-alone unit via the remote control or with a higher-
level system control.
To switch the machine on, perform the following steps in the specified order:
1. Switch the machine on using the master switch (#1).
The lamp (#2) next to the machine's master switch lights up.
2. Connect a stable, external compressed air supply to the maintenance unit (#5) on the
back of the machine. Set the pressure at the pressure gauge to at least 4 bar.
3. Operation with a higher-level system control: The solenoid valve must be unlocked to
enable the gas flow. To do this, connect PIN K and PIN A (see 2.2.5). Set a suitable
gas flow (40
–
80 l/min) at the throttle valve (#3); this will be audible from the nozzle.
Operation with an optional remote control
: Press the “GAS ON/OFF” switch on the
remote control (#6). This enables the gas flow to the plasma generator or interrupts it if
pressed again. Set a suitable gas flow (40
–
80 l/min) at the throttle valve (#3); this will
be audible from the nozzle. If the flow is suitable, the display lights up blue and the
“GAS ON/OFF” switch on the remote control lights up green. If the gas flow is
insufficient, the display on the flowmeter (#4) lights up red.
4. Operation with a higher-level system control: Once the gas flow has been established,
the plasma process can be started. To start the plasma process, connect PIN K and
PIN C (see 2.2.5). To end the plasma process, disconnect PIN K and PIN C. Note the
gas follow-on time of 2 seconds. During this time, the machine must not be switched off
or disconnected from the mains under any circumstances!
Operation with an optional remote control: To start the plasma process, press the
“PLASMA ON/OFF” switch on the remote control (#6). The swi
tch lights up blue and
plasma is generated visibly and audibly at the nozzle of the plasma generator. To stop
the plasma process, press the “PLASMA ON/OFF” switch on the remote control again.
Note the gas follow-on time of 2 seconds. During this time, the machine must not be
switched off or disconnected from the mains under any circumstances!
