11.15.9.3 (ID 1687) Supervision Unit Selection
Location in the menu: P3.13.9.3
Use this parameter to select the unit for the input pressure signal. It is possible to scale the supervision signal (P3.13.9.2) to process
units on the panel.
11.15.9.4 (ID 1688) Supervision Unit Decimals
Location in the menu: P3.13.9.4
Use this parameter to set the number of decimals for the input pressure signal unit. It is possible to scale the supervision signal
(P3.13.9.2) to process units on the panel.
11.15.9.5 (ID 1689) Supervision Unit Minimum Value
Location in the menu: P3.13.9.5
Use this parameter to set the minimum value of the input pressure signal. Enter the value in the selected process unit. For example,
an analog signal of 4...20 mA corresponds to the pressure of 0...10 bar.
11.15.9.6 (ID 1690) Supervision Unit Maximum Value
Location in the menu: P3.13.9.6
Use this parameter to set the maximum value of the input pressure signal. Enter the value in the selected process unit. For example,
an analog signal of 4...20 mA corresponds to the pressure of 0...10 bar.
11.15.9.7 (ID 1691) Supervision Alarm Level
Location in the menu: P3.13.9.7
Use this parameter to set the limit for the input pressure alarm. If the measured input pressure goes below this limit, an input pres-
sure alarm occurs.
11.15.9.8 (ID 1692) Supervision Fault Level
Location in the menu: P3.13.9.8
Use this parameter to set the limit for the input pressure fault. If the measured input pressure stays below this level for longer than
the set time, an input pressure fault occurs.
11.15.9.9 (ID 1693) Supervision Fault Delay
Location in the menu: P3.13.9.9
Use this parameter to set the maximum duration for the input pressure to stay below the fault limit before an input pressure fault
occurs.
11.15.9.10 (ID 1694) PID Setpoint Reduction
Location in the menu: P3.13.9.10
Use this parameter to set the rate of the reduction of the PID setpoint value when the measured input pressure is below the alarm
limit.
11.15.9.11 (ID 1407) Setpoint Reduction Interpolation Source
Location in the menu: P3.13.9.11
Use this parameter to select source for setpoint reduction interpolation or disable it. This function compares selection to input pres-
sure alarm and fault levels and accordingly adjusts setpoint reduction between 0 and setpoint reduction parameter. If disabled set-
point reduction will be equal to setpoint reduction parameter.
