4.1 Media compatibility / purge gas
The MAG turbomolecular pumps are suitable for pumping air and clean
gases.
The MAG ... iP have a purge gas device.
We would be glad to consult with you as regards the media which can safely
be handled with this unit.
Install a micropore filter when pumping media which contains dust.
Suited for venting or purging are all gases,
■
which will not cause corrosion or pitting in aluminium and steel and
■
which in connection with process deposits in the pump will not cause cor-
rosion or sticking.
For venting and as the purge gas we recommend inert gases like nitrogen or
argon. The temperature of these gases should be between 5 °C and 80 °C,
max. relative humidity should not exceed 10 ppm.
The gas must be clean.
In individual cases and after consultation also dry, filtered, oil-free air or fil-
tered ambient air may be used (filter mesh < 1µm).
Change the filters after some time, at least annually.
4.2 Interfaces
The MAG.DRIVE can optionally be equipped with the following interfaces:
■
RS 232
■
RS 485
■
Profibus
■
PLC (9-pin Sub-D)
■
Ethernet/IP (1-port)
■
EtherCat (in preparation)
If the interface modules are not covered, they will comply with type of protec-
tion IP 30, with cover to IP 54. The remainder of the pump and the frequency
converter will in the case of properly connected cables always comply with IP
54.
If you try to control via two installed interfaces, the interface in the CONTROL
slot will have the higher priority.
The address for the Fieldbus module can be set via the RS 232 service inter-
face or at the address switches.
The set default address is 126dec = 7Ehex.
