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.
Pr. 00-04 = 25 refers to the QI input voltage
Selection of Display Mode
Pr. 00-04
25: Displays the signal value of the QI analog input terminal, with
0~10V corresponding to 0~100%.
Set 100% flow rate through the controller, observe the reading displayed on the operation
panel and enter it to 00-17
Set 50% flow rate through the controller, observe the reading displayed on the operation
panel and enter it to 00-18
Set 0% flow rate through the controller, observe the reading displayed on the operation
panel and enter it to 00-19
Step 5. Send Run Command via Controller
Check that Pr. 00-09 is 1 (pressure control mode)

In case of power outage, connect SON-COM and turn on the power supply.
Step 6. Execute loop vent and verify there is no plastic material in the line and the
machine can function without any plastic material.
In the case of low pressure and low speed (within 30% of rating), the controller utilizes
"Manual Run" to operate each oil tank. While the system is in action, check if the oil line is
