Table 1-13 Switching the display levels
Flashing light signals that the status displayed by the Internal LED is identical with that in the
unselected controller.
Steady light signals that the status displayed by the Internal LED is not identical with that in
the selected controller.
Normally the display level switch will be in the position Controller II (master controller) so
that the main controller variable xII can be monitored. The display level I is only used for
startup procedures. The Automatic/Manual switch for the slave controller is possible in both
display levels, depending on the selection of the display level the main controlled variable xII
or the auxiliary controlled variable xI can be monitored. The display range of the digital x and
w display can be adjusted separately for both controllers by the parameters d*I and d*II if
necessary in connection with the linearizers so that both controllers can be displayed
physically correctly.
-- x-tracking
With S50 =1, x-tracking is selected for both controllers together (S50). The slave controller
follows up the internal setpoint or the controller output to the auxiliary controlled variable xI
in A-operation. The master controller triggers this function in A-operation or Internal of the
follow-up controller (Int I corresponds like A to disconnected cascade).
