Select Program using the UP or DOWN keys and press ENTER to confirm.
The pump offers two choices: mA and V (0-10V). Use the UP or DOWN
keys to make a selection and press ENTER to confirm your decision.
The pump displays a screen allowing you to set the speed for low signal
input (4mA or 0V). Use the UP and DOWN keys to scroll the display to your
chosen speed and press ENTER to confirm the figure.
The pump displays a screen allowing you to set the speed for high signal
input (20mA or 10V). Use the UP and DOWN keys to scroll the display to
your chosen speed and press ENTER to confirm the figure.
If a mistake is made, the user may press STOP at any point in the
sequence (before pressing ENTER on the high signal speed screen), and the
pump displays the previous screen.
The final press on ENTER causes the pump to configure the hardware and
programmed response data. It briefly displays a confirmation screen and a
warning that the analogue signal is not trimmed, and returns the user to the
Analogue setup menu. Example values are shown here.
