view and reset the fault and warning messages, and view the fault history
•
view actual signals
•
change parameter settings
•
change between local and external control.
To be able to start and stop the unit by the control panel, you must have the Run enable
signal and Start enable signal on (1) on the control board. Normally this means, that you
must have the operating switch on the cabinet door in ENABLE/RUN position. The control
panel must also be in local control mode. You can select the mode with the Loc/Rem key
