4. Operations
4.1. Before Switching On
Sections 4.1. to 4.3. refer only to operating the pump in its
delivery status, without display and control unit. The bridges
”venting release”, ”motor, TMP ON” and ”pumping station
ON” are fitted in the remote control plug.
Turbopump rotors rotate at high speed. When
the high vacuum flange is open there is a danger
of injury and of damage to the pump caused by
objects falling into the pump.
Therefore never operate the pump with open
high vacuum flange.
➡
With water cooling: Open cooling water supply and check
flow.
➡
Plug connecting cable (”Accessory”) into the TC 600 and
connect with power supply TPS 100 or DCU 100 on X2
(please see section 3.8.).
Please note:
The following pre-settings have been programmed:
– Running up time
15 min
– Rotation speed switchpoint 80%
– Automatic venting
50%
For further works settings please refer to the parameter over-
view in the operating instructions ”Pumping Operations With
the DCU”, PM 0547 BN. These settings can only be altered via
serial interface RS 485 via DCU / HPU or PC (please refer to
the respective operating instructions).
Take care when pumping hazardous gases.
Take note of all safety recommendations of the
gas manufacturer.
4.2. Switching On
➡
Switch on the turbopump with switch S1 on the power
supply.
– When air cooling is fitted the cooling fan is also switched
on via the TC 600.
– Once the self test has been successfully completed on the
TC 600 (duration approximately 10 seconds), turbopump
and backing pump (if connected) begin to operate.

4.3. Operations With The Remote Control
Unit
Remote control operations can be performed via the 15-pole
D-Sub connection with the designation “REMOTE” on the TC
600 (refer to section 3.12. and 3.13.).
Inputs 2 - 6 are activated if they are connected with the 24 V
on pin 1 (active high; please see section 3.13. “Connections
Diagram”).

Once operating voltage has been supplied and
on successful completion of the self-test on the
TC 600, the turbopump and any possible connec-
ted backing pump begin to operate.

Motor, Turbopump
When the pumping station is switched on and once the self
test has been successfully completed (duration approx.
10 sec), the turbopump is set in operation. During operations,
the turbopump can be switched on and off while the pumping
station is switched on. Thereby the turbopump will not be
vented.
Pumping Station
Any connected pumping station components are started up
(e.g. backing pump, venting valve, air cooling) and with simul-
taneous activation of the input ”motor, turbopump” the turbo-
pump is set in operation once the self test has been success-
fully completed (duration approx. 10 sec).
