5.4.5 Motor control
Frequency converter (applies to 3-phase motor)
Rotary vane pumps with variable rotation speed can be operated within a mains frequency range of 35
to 60 Hz. Start-up can be achieved via a ramp (run-up time: max. 30 sec), shutdown can take place
immediately.
Soft start
Starting the pump with an upstream soft start relay limits power input during run-up, thus preventing
mains-side load peaks. At the same time, the starting torque of the motor is limited, thus reducing the
mechanical load on the motor and pump.
Recommended setting:
● Startup voltage: >70%
● Ramp time: max. 5 s
5.5 Refilling operating fluid
WARNING
Danger of poisoning from toxic vapors
Igniting and heating synthetic operating fluid generates toxic vapors. Danger of poisoning if inhaled.
► Observe the application instructions and precautions.
► Do not allow tobacco products to come into contact with the operating fluid.
NOTICE
Risk of damage from the use of non-approved operating fluid!
Product-specific performance data are not achieved. All liability and warranty claims against Pfeiffer
Vacuum are also excluded.
► Use approved operating fluid only.
► Use other application-specific operating fluid only following consultation with Pfeiffer Vacuum.
