Connect the protective earth conductor of the motor cable (green/yellow wire) to the
earthing terminal (PE) at the front right of the cooling element.
Fig. 4: Connecting the motor cable
Connect the motor cable for the pump to the power terminal X1A of the electronic drive
unit.
Always ensure a safe connection to the protective earthing conductor (PE, protection
class I).
Lay the shielding of the motor cable on the grounding bar and secure with the shield-
ing clamp.
Connect the signal wires of the motor cable to the 15-pin D-sub connector at the X3B
socket of the electronic drive unit and screw in place.
Connect the motor cable to the pump (see p. 12, chap. 4.4).
Before applying the supply voltage, check the jumper position on the TCP 2000 (see
p. 13, chap. 4.5).
Before applying the supply voltage, check and secure the switch-on conditions in ac-
cordance with the operating manual of the pump.
WARNING
Overvoltage and uncontrolled switch-on conditions
Danger of the electronic drive unit being destroyed. Depending on how the terminals for
the control signals are connected and the jumper position on the corresponding circuit
board, it is possible that the connected pump may start up immediately when the mains
supply is switched on.
WARNING
Voltage with respect to ground
Danger of the electronic drive unit being destroyed.
Connection of TCP 2000 is only permissible on symmetrical networks. For 1-phase
inverters: max. voltage measured phase against neutral (L1-N) is 264 V. For 3-phase
inverters: max. voltage measured phase against phase (L1-L2, L2-L3, L1-L3) is 264
V. For supply networks, which exceed this value an isolating transformer must be
used.
CAUTION
Occurrence of discharge currents
The TCP 2000 is designed for fixed connection only. Discharge currents of > 3,5 mA can
occur.
Lay a second protective conductor in compliance with EN 50178, with a section of at
least 2.5 mm² at the connected pump (see operating instructions of the respective
pump) or at the inverter itself.

Checking the direction of rotation
Pay attention to the following characteristics when checking the direction of rotation:
– Blank flange loosely positioned on the vacuum flange becomes fixed during pump-
ing;
– Intake pressure, measured at the intake flange decreases (< 1000 mbar);
– Exhaust pressure increases (> 1000 mbar).
4.3 Commissioning of the housing version
With the version supplied in a housing, the electronic drive unit is already installed in a
housing (IP 54) and is supplied ready wired. The length of the motor cable and the kind
of mains connection (1-phase or 3-phase) need to be known already when the order is
placed.
Fig. 5: TCP 2000 version supplied in a housing
When selecting the installation site for the device, make sure that the space above and
below the cooling element at the back remains free from the floor to up above the top
edge of the unit, so that the generated heat can be dissipated.
Before applying the supply voltage, check the jumper position on the TCP 2000 (see
p. 13, chap. 4.5).
Before applying the supply voltage, check and secure the switch-on conditions in ac-
cordance with the operating manual of the pump.
Turn the master switch on the front of the housing to the position "0 = OFF".
NOTE
Damages to the pump!
Exchanging two phases when attaching the pump cable leads to a wrong direction of
rotation.
Pay attention to the markings at the pump cable when attaching the pump.
When checking the direction, only start the pump for a short time.
WARNING
Overvoltage and uncontrolled switch-on conditions
Danger of the electronic drive unit being destroyed. Depending on how the terminals for
the control signals are connected and the jumper position on the corresponding circuit
board, it is possible that the connected pump may start up immediately when the mains
supply is switched on.

12
Installation
Use the plugs to connect the connecting cable to the pump, and secure the plugs be-
fore connecting the electronic drive unit to the power supply (see p. 12, chap. 4.4).
Connect the mains plug of the power supply cable (mains voltage: 240 V AC max.).
Turn the master switch on the front of the housing to the position "1 = ON".
– Depending on how the control inputs are connected (see p. 13, chap. 4.5), the
pump will then start up directly.
– When the master switch is set to the position "0 = OFF" the electronic drive unit is
disconnected from the mains and powerless after approximately 5 minutes.
4.4 Connecting the pump
Fig. 6: Connecting the terminal box to the pump.
Connect the terminal box with the flanged-on X1 round plug into the mating plug on
the pump and lock the plug with the locking ring.
Connect the end of the cable with the X3 angled plug to the sealing gas valve/gas bal-
last valve of the pump and screw it in place.
Connect the cable end with the round plug X2 the cooling water monitor and screw it
in place.
– If the cable to the cooling water monitor with the X2 plug is too short because the
cooling water monitor has not been installed right next to the pump, then you can
use an extension cable (cable on request).

Switching on When the TCP 2000 is switched on, the value for the parameter CP.1 (current speed) is
shown on the display.
The FUNC./SPEED button is used to switch between the parameter value and the pa-
rameter number.
The arrow keys /START und STOP/are used to increase/decrease the parameter
number or value of variable parameters.
Parameter values are generally adopted as soon as they are changed and saved in the
non-volatile memory. The only exception is the parameter CP2. If the value of this pa-
rameter is changed, a dot appears after the new value. By pressing the ENTER/F/R but-
ton the value is confirmed and only then overtaken.
Deleting error messages
If an error occurs during operation, the current display is overwritten with the flashing er-
ror message. Error acknowledgement is only possible at rotation speed =’’0’’.
Press the ENTER/F/R button to clear the error message from the display.
Rectify the cause of the error.
Switch the reset input to 0 V temporarily or disconnect the electronic drive unit from
the mains for approximately 15 sec, in order to delete the error in the electronic drive
unit and enable the vacuum pump to start up again.

Operation
*) from software 010200
5.2 Profibus operation
Connections For the connection of the profibus the operator offers two 9 pole D-sub-sockets (accord-
ing to DIN 41652 part 1). The assignment is as follows:
Configuring the con-
nection To start Profibus communication, the TCP 2000 must be configured by a Profibus master
using the enclosed GSD file.
Set valid and unique Profibus interface address using parameter CP2 (therefore see
chap. 5.1).
Modules The standard module, which is available for control has the following out- and input data:
Output data
For releasing the error reset the bit 1 must me set and afterwards reset. Between setting
and resetting a minimum time of 1 s must be kept.

Malfunctions
6 Malfunctions
6.1 General
Malfunctions on the pump or electronic drive unit always generate a warning or error
message which can be displayed on the display of the display and control unit of the elec-
tronic drive unit. The pump is switched off as a result of any occurring errors.
6.2 Error codes
WARNING
Automatic start-up after error acknowledgement!
After a power failure or if errors has been rectified and acknowledged the pump will au-
tomatically run-up.
Take suitable safety measures to prevent injuries/damages.
WARNING
Danger of injury from moving parts!
After power failure or motor shutdown due to overheating, the motor may restart auto-
matically.
Secure the motor so that it cannot be switched on while any work is being performed
on the pump.
If necessary, dismantle the pump from the installation for inspection.
Display Error Value Cause / remedy
E.buS Watchdog 18 The selected monitoring time (watchdog) for the com-
munications between the display and control unit and
the electronic drive unit has been exceeded.
E.Cdd Drive data calculation 60 An error has occurred during the automatic stator re-
sistance measurement.
E.dri Driver relay 51 The relay for the driver voltage on the power section
has not energized after a given controller enable, or it
has not de-energized after an open controller enable.
E.EEP EEPROM defective 21 Operation can be resumed after a reset (without sav-
ing in the EEPROM).
E.EF External error 31 CP14 = 0 : Run-up time exceeded (see CP23 and
CP24)
CP14 = 1 : Flow of cooling water interrupted (cooling
water monitor)
CP14 = 2 : Oil level in the OnTool Booster 150 too low
CP14 = 3 : Error motor temperature sensor
CP14 = 4 : Maximum motor temperature exceeded
E.LSF Charging circuit 15 The charging shunt relay has not energized. This oc-
curs temporarily during the switch-on phase, but
should normally be reset immediately and automati-
cally. If the error message persists then investigate
the following potential causes:
– Charging shunt defective
– Input voltage incorrect or too low
E.nOH Cooling element tempera-
ture back to normal
36 The temperature of the cooling element is back in the
permitted operating range. The error can be reset.
E.nOHI Interior temperature back to
normal
7 Temperature in the interior EOHI no longer too high,
interior temperature has dropped by at least 3°C, er-
ror can be reset.
