3.6.7.3 Soft Pump
This valve may be used to control pressure ramps during pump down. The P parameter of the pressure controller requires
correct adjustment. This parameter must be set once during system setup and is stored in the device memory which is
power fail save. Based on the soft pump controller configuration, the valve is able to run fast and accurate pressure control
cycles. The P parameter can be evaluated using below instruction.
Local operation:
(‘Control View’ resp. ‘Control Performance Analyzer’)
Go to ‘Tools / Terminal’ menu and do the «Pressure
control configuration» refer to chapter: 3.6.7 Pressure
control configuration.
Note: It’s not possible to do «Pressure control
configuration» via remote operation.
Note: To optimize soft pump algorithm of pressure controller refer to chapter «Tuning of pressure control performance».
