4 change-over between set-point 1/differential 1 and set-point 2/differential 2 by
means of digital input (open – set 1, closed set 2)
5 output related to set-point 2 maximum alarm
6 output related to set-point 2 minimum alarm
7 output related to set-point 1 maximum alarm
8 output related to set-point 1 minimum alarm
9 output related to set-point 1 maximum/minimum alarm
10 output related to set-point 2 maximum/minimum alarm
(35) establishes whether the type of regulation is ON/OFF (value 0) or PWM (value 1)
(36) indicates if dead band is present (value 1) or not (value 0)
(37) indicates change-over point ON of relay compared to set-point set by
"dependency" parameter: the change-over point is calculated adding an "INO"
percentage of the differential (from -100% to +100%) to the set-point.
(38) indicates change-over point OFF of relay compared to the point where ON
change-over took place: the change-over point OFF is calculated adding a "DF0"
percentage of the differential (from -100% to +100%) to the ON-point.
Note: default values of these parameters depend on the operating mode and
number of channels, as indicated in the tables below:
