The operating mode of the Trim function can be defined in the Trim Parameter screen. A
distinction is made between percentage and absolute comparison levels. Furthermore, the
main operating mode of the setpoint/actual value comparison interval is defined.
Operating Mode Percent
The setpoint/actual value comparison is based on a percentage level calculation depending
on the default setpoint. Example calculation based on the setpoint 1.0 ppm.
Example calculations:
PV >> SP 25.0%
= 1.25 ppm
•
Actual value 0.80 ppm
•
-> Level -2.5%
PV > SP 10.0%
= 1.10 ppm
•
Actual value 0.80 ppm
•
-> Level -1.0%
PV < SP -10.0%
= 0.90 ppm
•
Actual value 0.80 ppm
•
-> Level +1.0%
PV << SP -25%
= 0.75 ppm
•
Actual value 0.80 ppm
•
-> Level +2.5%
