25. PID2 PARAMETERS MENU
25.1. Overview
This menu defines the parameters of the digital regulator PID2 as well as the parameters used in 2-zone mode.
To activate the PID2 regulator, set C291a = 7: 2 PID (PID CONFIGURATION MENU).
Once activated, the PID2 regulator has the same functionality and operates in line with the standard PID (PID
PARAMETERS MENU). The output of the standard PID regulator is algebraically summed with the output of the PID2
regulator.
Add “200” to the parameter codes pertaining to the standard PID to obtain the relevant parameter codes for PID2.
Example: P236 for standard PID corresponds to P436 for PID2.
To enable the 2-zone mode, set C291a = 5: 2-Zone MIN or 6: 2-Zone MAX (PID CONFIGURATION MENU).
Once the 2-zone mode is enabled, the standard PID regulator operates on the system with the larger error (minimum
feedback in respect to its reference, 2-Zone MIN) or with the smaller error (maximum feedback in respect to its
reference, 2-Zone MAX).
In 2-zone mode, parameters P236..P260 pertain to the system where the error results from the reference selected with
C285 and from the feedback selected with C288, whilst parameters P436..P460 pertain to the system where the error
results from the reference selected with C286 and from the feedback selected with C289.
NOTE The PID2 regulator is disabled when operating in 2-zone mode.
Please refer to the block diagram in Figure 69.
