    Operation 7 Operation 7.1 Configuring the connections with the Pfeiffer Vacuum parameter set The electronic drive unit is pre-configured with the factory default basic functions and is ready for opera- tion. For individual requirements, you can configure most connections for the electronic drive unit with the parameter set.

  • Page 31: Configure Analog Output

    Only for vacuum pumps with a temperature management system (TMS) The standard version of the TC 110 electronic drive unit can operate a maximum of 2 accessory outputs via connection cables. As a result, parameters [P:037] and [P:038] are without effect.

    ► Make sure that the gas mode is set correctly by [P:027] in the electronic drive unit. ► Consult Pfeiffer Vacuum before you use gases with higher molecular masses (> 80). High gas throughput and high rotation speed lead to strong friction heating of the rotor. To avoid over- heating, power to rotation speed characteristics are implemented in the electronic drive unit.

  • Page 33: Set Value Power Consumption

    Operation characteristic enables the operation of the turbopump at any rotation speed with the maximum permissi- ble gas throughput without thermally overloading the turbopump. The maximum power consumption de- pends on the gas type. 3 characteristics are available for the parameterization in order to completely exhaust the turbopump's capacity for each gas type.

  • Page 34: Rotation Speed Switch Points

    Operation 7.2.4 Rotation speed switch points You can use the rotation speed switch point for the “turbopump operational for the process” message. Exceeding or underrunning the active rotation speed switch point activates or deactivates a signal at the pre-configured output on the electronic drive unit and at the status parameter [P:302]. Rotation speed switch point 1 [P:017] = 0 f (%)

  • Page 35: Rotation Speed Setting Mode

    3. Check the set rotation speed (parameter [P:308] or [P:397]). 7.2.6 Standby Pfeiffer Vacuum recommends standby mode for the turbopump during process and production stops. When standby mode is active, the electronic drive unit reduces the rotation speed of the turbo pump.

  • Page 36: Confirming The Rotation Speed Set Value

    Fluctuations in the power consumption of idling turbopumps and varying fore-vac- uum pressures of the backing pumps require individual settings of the interval operation. Pfeiffer Vacuum recommends interval operation between 5 and 10 hPa. A pressure gauge and a dosing valve are required to set the switching thresholds.

  • Page 37: Backing Pump Standby Mode

    ► Set the connections via the parameters [P:035], [P:036], [P:037] or [P:038]. The standard version of the TC 110 electronic drive unit can operate a maximum of 2 accessory outputs via connection cables. As a result, parameters [P:037] and [P:038] are without effect.
