Send the maximum pressure command through the controller and then check the multi-function display
page to enter this value into Pr.00-14.
Send a half pressure command through the controller and then check the multi-function display page to
enter this value into Pr.00-15.
Send the minimum pressure command through the controller and then check the multi-function display page
to enter this value into 00-16.
Example: If the pressure sensor indicates 250bar at 10V. If the controller’s maximum pressure of 140bar
corresponds to 10V, then Pr.00-07=140. Set the pressure as 140bar by using the controller, the voltage
value shown on the display is about 56.0 (140/250 * 100%). Enter this value into the Pr.00-14. Then set
the pressure as 70bar on the controller, and now the value displayed on the keypad is about 28.0
(70/250 * 100%). Enter this value to the Pr.00-15. Then set the pressure as 0 bar on controller, and the
voltage value shown on the keypad is about 0.0 (0/250 * 100%). Enter this value in the Pr.00-16.

Send the 100% flow rate through the controller and then check the multi-function display page to enter this
value into Pr.00-17.
Send the 50% flow rate through the controller and then check the multi-function display page to enter this
value into Pr.00-18.
Send the 0% flow rate through the controller and then check the multi-function display page to enter this
value into Pr.00-19.
