3.9. Connecting The Sealing Gas Valve
To protect the pump, particularly where corrosive or dust
producing processes are involved, it is necessary to use
sealing gas. Connection is made via the sealing gas valve
(please see “Accessories”).
Please refer to Section 9.1. ”Dimensions Diagram” for the
sealing gas connection.
Please refer to Operating Instructions PM 800 229 BN for
details on installing the sealing gas valve and adjusting the
sealing gas flow.
3.10. Connecting The Remote Control Unit
Remote control options for various functions are provided
with the connection ”REMOTE” on the TC 600 via the 10 pole
screw connector plug (maximum cable cross section
0.14 - 1.5 mm2/connection).
Shielded cable should be used. Shielding has to be
connected with the TC casing on the plug side of the TC 600
by using cable clamps.
The inputs 2 - 6 are activated by connecting them to the + 24V
on pin 1 (active high) (please see Section 3.13. ”Connections
Diagram”).
Pin Arrangement And Remote Plug Functions
(please see following table).
When connecting supply voltage, the turbopump
is started.
