    DESIGN AND FUNCTION Series 642 3.2.1.1 Way of operation The controller compares the actual pressure in the process chamber given by the pressure sensor with the preset pressure. The controller uses the difference between actual and set pressure to calculate the correct position of the control valve. The controller drives the control valve into the correct position and the actual pressure again equals the set pressure.

  • Page 36 INSTALLATION Series 642 4.6.6.2 Sensor delay adjustment Sensor delay adjustment effects: Stability Default value is 0. Adjustment range is from 0 to 1.0s. Pipes and orifices for sensor attachment delay response time and so badly impact pressure control stability. By adapting this parameter to the approximate delay time stability problems can be reduced. But control response time will be slowed down by this measure.

Adjustment range for Setpoint Ramp is from 0 to 10 s. This parameter defines the time that is used to decrease / raise pressure between 2 setpoints. Especially in pressure decrease situations at low flows pressure response can be improved much by adapting setpoint ramp time.
