Available control modes:
•
Manual (default mode)
•
4-20mA (Ds500+ only)
•
Contact (Ds500+ only)
Note: The pump will not start when in 4-20mA or contact mode
if there is a pump head issue. This is to prevent unintentional
operation when remotely controlled. Manual operation is still
possible with a confirmation dialogue.

10.3.1.1 4-20mA Calibration
External control signals can be used to control the flow of the
unit. To do so, calibration must be performed:
Figure 15. - 4-20mA Calibration (1)
The above screen is awaiting a 20mA input signal (
±
1mA).
Once 20mA is reached, confirmation is required:
Figure 16. - 4-20mA Calibration (2)
At this point, 20mA can be set to to suit the application,
e.g., 20mA = 65 rpm:
Figure 17. - 4-20mA Calibration (3)
The same procedure needs applying to the 4mA input signal:
Figure 18. - 4-20mA Calibration (4)
At this point, 4mA can be set to to suit the application,
e.g., 4mA = 0 rpm.
Once calibration is complete, the speed can be set proportionally
by the external control signal.
