Pumphead Speed Setpoint
The speed setpoint is a 16-bit unsigned integer value that represents the speed of the
pump head in 1/10th of RPM. For example 1205 represents 120.5 RPM.
Set Flow Calibration
This parameter is used to set the flow calibration value from the fieldbus interface. The
value is a 16 bit unsigned integer representing μl per revolution of the pumphead. Note
that this value is only used if bit 5 of the Control Word is enabled.
Ignore Leak Detection Sensor
If bit 6 of the control word is enabled, the following run screen will be displayed.
