15. PID MULTIREFERENCES MENU
15.1. Overview
This menu includes the parameters for the utilisation and allocation of PID Multireferences from digital inputs.
The reference sources are based on the setup in parameters C285 to C287 (see the PID CONFIGURATION MENU).
The overall reference also depends on the multireferences that are already set (if any) or on the reduction percent of the
reference itself (see the REFERENCE VARIATION PERCENT MENU).
Configuration example:
PID Configuration Menu
C285 Source of PID reference 1 = 2: AIN1
C286 Source of PID reference 2 = 0: Disable
C287 Source of PID reference 3 = 0: Disable
Digital Inputs Menu
C188a Input for PID Multireference 1 = 7: MDI7
C188b Input for PID Multireference 2 = 8: MDI8
C188c Input for PID Multireference 3 = 0: Disable
PID Multireferences Menu
P081a PID Reference 1 (Mref 1) = 1.0 bars
P082a PID Reference 2 (Mref 2) = 1.5 bars
P083a PID Reference 3 (Mref 3) = 2.5 bars
PID Parameters Menu
P257 Gain for PID scaling = 0.1
When AIN1 analog input is set to 100%, the pressure reference is 10 bars
(100%*P257 =10.0).
Supposing that AIN1 is set to 43%, the references below are obtained based on the combination of the digital inputs
configured as multireferences, and based on the function allocated to parameter P080a.
P080a = 0: Preset Ref. If both digital inputs configured as Multireferences are not activated, the overall reference is
given from AIN1 analog input selected as the first PID reference (C285):
P080a Multireference Function = Preset Ref.
P80a = 1: Sum Ref. If both digital inputs configured as Multireference are inactive, the overall reference is given from
AIN1 analog input selected as the first PID reference (C285). For the combinations where at least one of the digital
inputs configured as multireference is active, the resulting reference is the sum of the value for AIN1 plus the value for
the selected multireference.
P080a Multireference Function = Exclusive Preset Ref.
