Operation
5.1
Start-up
To operate the system, the following points must be met:
-
The main switches of the connected PS2000 current source must be switched on.
-
The emergency stop circuit must be connected correctly.
-
The CAN bus cables must be connected, both ends must be terminated with
terminal resistors and the correct CAN bus address on the rear side of the current
source must be set.
-
The baud rate of the current source is 500 kBd. When programming the higher level
control system, this must be taken into account and set correctly.
-
The plasma generator must have a gas supply.
-
All additional machines/components must be correctly connected.
If these points are met, you can use the higher level PLC to control your plasma process.
Please note that it is essential that a gas flow is present in order to operate the plasma
generator. A test to ensure sufficient gas flow is present using the higher level PLC is
recommended. This can be done using a SFAB flow meter type from Festo, for example.
This check then has to be provided in the overall system. Before activating the high voltage
for plasma generation, there must be a gas flow through the plasma generator for at least 2
seconds.
Attention
–
Damage to machine!
The plasma generator may be damaged if it is operated with no gas or too little gas.
- Never switch on the high voltage before sufficient gas is flowing through the plasma
generator!
