● Power supply: The turbopump power supply must apply to the requirements of dou- ble insulation between mains input voltage and operating voltage according to the reg- ulations of IEC 61010 and IEC 60950. Therefore Pfeiffer Vacuum recommends to use exclusively original-power packs and -accessories. Only in this case Pfeiffer Vacuum is able to guarantee the compliance of the European and North American guidelines.
Service. Functional safety The drive unit (electronic drive unit) TC 400 performs the safety function "Safe Limited Speed" according to EN 61800-5-2. In case of excess rotation speed the commutation of the pump motor is switched off and the drive transferred into the safe condition.
Product description Product description Product identification The electronic drive unit TC 400 is an integrated component of the turbopump. It's pur- pose is to drive, monitor and control the entire pump. Characteristics TC 400 Connection voltage TC 24 V DC ±10 % 48 V DC ±10 %...
High Density D-sub 26 pole female socket for the connection of a remote control. RS485 M12 socket with screw coupling for the connection of a Pfeiffer Vacuum control unit or a PC. The use of a Y-connector enables the series connection in a bus system.
Remote control is possible via the 26-pin D-sub connector labelled "remote" on the elec- tronic drive unit. The accessible individual functions are mapped to "PLC levels". Remove the remote plug from the TC 400 and connect a remote control unit. Pin as- signment of the connector according to table.
The digital inputs at connection "remote" are used to connect various functions of the electronic drive unit. Functions are assigned to the inputs DI1 - DI2 ex factory. These can be configured via interface RS-485 and the Pfeiffer Vacuum parameter set. DI1 (Enable venting) / Pin 2...
The digital outputs at the connection "remote" can be loaded with a maximum of 24 V / 50 mA per output. All outputs listed below are configurable by the Pfeiffer Vacuum pa- rameter set via interface RS-485 (description related to factory settings).
5.2.5 RS-485 One Pfeiffer Vacuum display and control panel (DCU or HPU) or an external PC can be connected respectively to the electronic drive unit via Pin 24 and Pin 25 of the connec- tion "remote" on the electronic drive unit.
Connection "RS-485" Connections A Pfeiffer Vacuum display and control panel (DCU or HPU) or an external PC can be connected to the electronic drive unit via the connection designated "RS-485". The inter- face is electrically isolated from the maximum supply voltage of the electronic drive unit.

Ensure the gas mode is correctly set. Contact Pfeiffer Vacuum before using gases with a greater molecular mass (> 80). ● Gas mode "0" for gases with the molecular mass >39, e.g. argon. ● Gas mode "1" for gases with the molecular mass 39.
The Pfeiffer Vacuum parameter set To avoid rotation speed fluctuations, Pfeiffer Vacuum recommends setting a some- what lower frequency in rotation speed setting mode. 7.4.4 Set value power consumption Adjust the parameter [P:708] to the desired value in %.
The Pfeiffer Vacuum parameter set When the pumping station [P:010] is switched on, the rotation speed switchpoint 1 is the signal generator. When the pumping station is switched off, signal output and status que- ry are based on the rotation speed switchpoint 2. The signal output is governed by the hysteresis between the two switchpoints.
Pfeiffer Vacuum recommends the intermittend mode between 5 and 10 hPa. A pressure gauge and a dosing valve are required to set the switching thresholds.
The signal can also be used for switching a fore-vacuum safety valve. 7.4.11 Standby mode for the backing pump Connected Pfeiffer Vacuum backing pumps with speed control can be put in standby by configuring a digital output. The pump status signal switches off the backing pump when the turbo pump reaches the specified power consumption level;...
