How to Change Parameters
Pressing the Accept key ("acc") for more than 3 seconds will active parameter change mode. The user can then select the parameters by pressing the up or down key. When parameter number is correct, pressing Accept again will enter parameter number. Display will show parameter value.
Pressing the up or down key will change the parameter itself. Display will flash indicating parameter editing mode. Pressing the Accept key will accept the new parameter value. All digits will flash while being accepted.
After releasing all keys, the next parameter number will be presented on the display. When no key is pressed after 3 seconds, the display will show the actual output pressure. When unit is initially powered up allow approximately 10 seconds for the unit to boot-up before changing parameter settings. Parameter numbers 0, 4, 6, 8, 9, 12, 13, 14, 18, 19, 20, and 21 are accessible to edit. All other parameters are fixed.

Parameter 6 - Set Output Signal
Parameter 6 is used to set the type of output signal to your PLC. This parameter is used as follows:
Output Signal Option 0= Digital Output - PNP
- Factory set at "0", Non-Adjustable
Output Signal Option P= Digital PNP or Analog 1-10V
- Factory set at "1" for Analog Signal
- Concert to Digital PNP by changing parameter to "0" setting
Output Signal Option N= Digital NPN or Analog 1-10V
- Factory set at "1" Analog Signal
- Convert to Digital NPN by changing parameter to "0" setting
Output Signal Option M= Analog 4-20 mA
- Factory set at "2", Non-Adjustable

Parameter 8 - Adjust Span Analog Output Signal
Set value is a % of Full Analog range. As an example, for a 0-10V output signal, the original factory setting of 100% will give you an adjustment of 0-10V. If you reset Parameter 8 to 50%, the new output range would be 0-5V, or 50% of the full range.

Parameter 19 - Set Maximum Preset Pressure
Pressure correction allows the user to set a maximum pressure as a percentage of secondary pressure F.S.
Example: If F.S. is 10 bar, set parameter 19 to 50 for maximum preset pressure of 5 bar.
Pressure correction also affects the minimum preset pressure in parameter 18.
Example: If F.S. is 10 bar and parameter 18 is set to a value of 100 (1 bar), and parameter 19 is set to 50%, then the actual minimum pressure seen is 0.5 bar.
