Page 28: Optimize Control Settings
Log or store the default control settings Ensure process variations are minimized or eliminated Make changes with small increments Request support from a trained Bronkhorst service engineer Please refer to the specific Liquid Flow Controller manual for more details and instructions. 5.1 Changing Filter Settings Controller speed can be increased by changing or disabling output and sensor filters. -
Page 29: Actuator Control Speed
This setting is default not used and therefore set to value 0. In Bronkhorst flow setups it can be useful if the volume between the sensor and valve is relatively large (e.g. when the sensor and actuator are mounted away from each other). -
