Time-out
For setpoint adjustment in Normal mode, the controller will exit the setting after 20 seconds automatically. However, for setpoint
adjustment in Service (PS) mode, there is no time limit. The controller remains on the PS mode until the user completes the
whole process.
Note
Only those parameters that apply to a particular program appear on the display or in the sequence in programming.
For example, if the second analogue input is not used, X2 values and selections will not appear.
A software tool (S3341A031EN0) for controller application selection and parameter adjustment is available. It is a user-friendly Windows

Parameters can be hidden from display if desired by using the software tool.
