    Installation NOTICE The water cooling circuit may be damaged if an unregulated mains supply is used Using unregulated mains water can lead to water circuit clogging due to limescale deposition. This may necessitate complete cleaning and overhaul of the water cooling circuit. Furthermore, the presence of micro-organisms such as algae and biological substances such as bacteria can lead to cooling problems in the pump.

    Installation Absence of emergency stop The vacuum pump is not equipped with an emergency stop device (EMS) or a lock-out de- vice. The vacuum pump is designed to be integrated into equipment fitted with an emer- gency stop device. ● When activated, the EMS of the equipment must switch off the vacuum pump. Operation in local mode There is no device to warn that the pump is operating in local mode.

  • Page 27: Shutting Down The Pump

    Operation 6.3 Shutting down the pump 6.3.1 Pumping shutdown NOTICE Risk of damaging the pump by generating an electric arc The pump and its electronic drive unit must not be disconnected from the electrical network before the rotor completely stops rotating and the unit is isolated from the electrical network: an electric arc is created when the circuit is interrupted, which damages internal components.

  • Page 28: Powering Off

    Operation When a power failure occurs, the rotor remains suspended by the energy emitted by the motor’s coun- ter-electromotive force, until the rotor rotation speed is low enough that it can rest on the landing bear- ings without being damaged. If the power is restored before the minimum speed is reached, the pump recovers its initial speed with- out any disturbance.

    The integrated heater band heats the pump to an adjustable temperature (refered to as temperature setpoint) to prevent the effects of condensation. The temperature setpoint depends on the application the pump is to be used for. Contact Pfeiffer Vacuum’s applications department for advice in choosing the correct temperature setpoint.
