 Parameter 00-07 = related pressure value of the pressure command at 10V
Maximum pressure command
Setting value
of Parameter
00-07
0~250Bar
 Send the maximum pressure command through the controller and then check the
multi-function display page to enter this value into Parameter 00-14
 Send a half pressure command through the controller and then check the multi-function
display page to enter this value into Parameter 00-15
 Send the minimum pressure command through the controller and then check the multi-function
display page to enter this value into Parameter 00-16
Example: If the pressure sensor indicates 250bar at 10V. If the maximum pressure on the
controller is 140bar and corresponds to 10V, then Parameter 00-07=140.
Set the pressure as 140bar through the controller, the voltage value shown on the
display is about 56.0 (140/250 * 100%). Enter this value into the Parameter 00-14.
Then set the pressure as 70bar on the controller, and now the value displayed on
the keypad panel is about 28.0 (70/250 * 100%). Enter this value to the Parameter
00-15. Then set the pressure as 0 bar on the controller, and the voltage value shown
on the display is about 0.0 (0/250 * 100%). Enter this value in the Parameter 00-16.
 Parameter 00-04 = 25 for QI input voltage
Selection of multi-function display
Setting value
of Parameter
00-04
25: display the signal value of the analog input terminal OI with 0~10V
mapped to 0~100%
 Send the 100% flow rate through the controller and then check the multi-function display page
to enter this value into Parameter 00-17
 Send the 50% flow rate through the controller and then check the multi-function display page
to enter this value into Parameter 00-18
 Send the 0% flow rate through the keypad panel and then check the multi-function display
page to enter this value into 00-19
Step 5. Bleed the circuit and make sure if there is any plastic material in the barrel.
The machine can start operation only when there are no plastic materials inside the
barrel.
 Parameter 00-09 = 1 for pressure control mode
