Installation
21
Establish the mains supply for the relay box according to the accessory operating in-
structions.
Sealing gas connec-
tion
The turbopump must be operated with sealing gas to protect it, such as in the case of
unclean processes or high gas throughput. The supply is made via a sealing gas valve
or alternatively via a sealing gas throttle without control. The activation of the control
valve for the sealing gas connection is not pre-installed in the electronic drive unit and
has to be configured via their interfaces.
The permissible connection pressure is max. 150 kPa absolute.
●
When operating the pump with more than 50 % of the maximum gas throughput, seal-
ing gas must be used to ensure rotor cooling.
●
The sealing gas flow rate amounts 17.5-20 sccm for the HiPace 800 P.
Sealing gas supply with control valve
Unscrew the locking screw with seal ring out of the sealing gas connection.
Screw the sealing gas valve with seal ring into the sealing gas connection.
Insert the control cable of the accessory into a free accessory connector on the TC
400 and tighten.
Make the settings and control via the interfaces of the electronic drive unit.
Install the sealing gas supply (e.g. inert gas) via a connection adapter or on the inlet
side (G 1/8") of the control valve.
Sealing gas supply without control valve
Unscrew the locking screw with seal ring out of the sealing gas connection.
Screw the sealing gas throttle with sealing ring into the sealing gas connection.
