4.1 Switching ON The Electronic Drive Unit
➡Make the connection TCP - turbopump in accordance
with Section 3.5.
➡Make the cooling water connection turbopump.
➡Switch the TCP into the mains via contactor Kx.
Providing the electrical connections have been carried out in
accordance with Wiring Diagram PM 021 801-S, the control
contains optimum interlocking. Components can be selected
depending on the application.
Switching ON Via Pumping Station Control
Unit TCS 130
➡Switch on main switch S7.
➡Switch on the pumping station with S1.
➡Switch on any possible heating with S2.
4.2 Start-Up, Turbopump
After switching on, the turbopump begins to run. Operating
fluid monitoring becomes active when 50% of the final rotati-
on speed is attained. If the flow of operating fluid is interrup-
ted for more than 20 seconds the turbopump is switched off.
When a turbopump is operated for the very
first time bubbles can form in the operating
fluid feeder line and this can cause the turbo-
pump to be switched off owing to a lack of ope-
rating fluid.
➡In the event of a malfunction re-start with RESET, ensuring
that the electronic drive unit is supplied with voltage and
that the reset key is depressed for at least 5 seconds.
If a TPH 5000 is in use, the start-up current is 10A. When the
nominal rotation speed is attained the current reduces to
approximately 5A and can increase, depending on the gas
load, to 10A. The start-up current is 5A where pumps with a
rotation speed of 600 Hz (TPH/TPU 2200/1600) are involved.
4.3. Operations At Nominal Rotation Speed
When 95% nominal rotation speed is exceeded the maximum
current is reduced to 3A to prevent the pump rotor from
overheating from too high a gas load (not applicable on the
TPH 5000).
4.4. Stand-By Operations
Stand-by operations are recommended where high gas loads
or process interruptions are involved. In this case the rotation
speed is reduced and the current is maximum 5A. The danger
of rotor overheating does not arise owing to the slower circu-
lation speeds of the rotor blades.
4.5 Switching OFF
The switching off procedure is as follows:
➡Switch off the heating and allow the pump to cool.
➡Close the high vacuum valve (if provided).
➡Switch off the pumping station.
➡Vent the pumping station with the venting control unit
(automatic) or manually.

3.9. Operating The Electronic Drive Unit
TCP 5000 With Accessories
Control Units
The Electronic Drive Unit TCP 5000 can be operated with
Pumping Station Control Unit TCS 130. A Venting Control Unit
TCF 103 or a Valve Control Unit TCV 103 can be integrated in
the TCS 130.
➡Connect the TCP to TCS 130/X4.
Controller
The following operating functions can be displayed if
Controller TCI 001 is in use:
– Lubricant insufficiency
– Pump temperature too high
– TCP temperature too high
– TCP switched on
– Pump accelerates
– The pump rotation speed < nominal rotation speed
– The pump rotation speed < nominal rotation speed switch-
point
– The pump rotation speed = nominal rotation speed
– Stand-by
➡Connect the TCI 001 to plug X9 via the connecting cable.
The TCI is designed to provide remote displays.
Only safety low voltages (SELV) may be
connected to the serial interface plug.
The electrical connections must be carried out in accordance
with Operating Instructions PM 800 107 BE for the TCI 001.
