With the maximum pressure set by the controller, observe the associated value displayed

on the operation panel and set it to 00-14.
With the controller setting at half the maximum pressure, observe the associated value

displayed on the operation panel and set it to 00-15.
With the controller setting at the lowest pressure, observe the associated value displayed

on the operation panel and set it to 00-16.
Example: 10V on the pressure sensor corresponds to 250bar. If the maximum pressure
on the controller is 140bar and corresponds to 10V, the Pr. 00-07=140. Set 140bar
through the controller and the voltage reading displayed on the operation panel is
approximately 56.0(140/250*100%). Enter this value to Pr. 00-14. Next, set 70bar
through the controller and the voltage reading displayed on the operation panel is
approximately 28.0 (70/250*100%). Enter this value to Pr. 00-15. Lastly, set 0bar
through the controller and the voltage reading displayed on the operation panel is
approximately 0.0(0/250*100%). Enter this value to Pr. 00-16.
Example: 10V on the pressure sensor corresponds to 250bar. However, the maximum
pressure on the controller is 140bar and corresponds to 7V. As a result, Pr. 00-07=
140/7*10=200. The following steps are the same as described in the previous
example. Set 200bar through the controller first, followed by setting 100bar, and
0bar in the last step. Enter the corresponding values to the associated parameters.
