  • Page 36: Operating Modes

    ► 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 37: Run-Up Time

    Operation 7.2.3 Run-up time The turbopump run-up is time-monitored ex-factory. There are various causes of prolonged run-up times, for example: ● Excessive gas throughput ● Leak in system ● Setpoint of the run-up time too low Set parameter [P:700] 1. Where applicable, eliminate any external and application-related causes. 2.

  • Page 38: 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 39: Confirming Speed Specification

    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 40: Backing Pump Standby Mode

    2. Use this signal for the control of a fore-vacuum safety valve. 7.2.9 Backing pump standby mode In case you are using a Pfeiffer Vacuum backing pump with rotation speed control, this can be used in standby mode by configuring the digital output [P:019] or [P:024]. The power consumption of the turbo- pump has a direct influence on the rotation speed of the backing pump.

    Operation Configuring the sealing gas valve ► Using parameter [P:050], switch a connected sealing gas valve on or off via the pre-configured output. Monitoring the sealing gas 1. Set the selected parameter to "13". 2. Set the parameter [P:791] to the desired sealing gas flow for the warning threshold. 3.

  • Page 42: Inputs

    The digital inputs at the "remote" connection are used to switch various electronic drive unit functions. As a factory default, inputs DI1 – DI2 have that can be configured with the Pfeiffer Vacuum parameter set via Profibus or the RS-485 interface.

  • Page 43: Outputs

    The digital outputs at the "remote" connection have a maximum load limit of 24 V/50 mA per output. All outputs listed below are configurable with the Pfeiffer Vacuum parameter set via Profibus or the RS-485 interface (description relates to factory settings).

  • Page 44: Relay Contacts (Invertible)

    ► Connect only suitable devices to the bus system. A Pfeiffer Vacuum display and control unit (DCU or HPU) or an external PC can be connected via pins 24 and 25 of the electronic drive unit's "remote" connection. A USB interface (PC) can be connected via the USB/RS-485-converter.
