Figure 41 Functional schematic for Bias/Gain function block.
Description
The Bias/Gain function block can be used for biased
external feedforward control or to set several unit
controllers, such as boiler masters, from one controller
output, such as a plant master. A functional schematic of
the block is shown in the previous illustration for reference.
Function Notes
Supports Out of Service (OOS), Initialization Manual
(IMan) Local Override (LO), Manual (Man), Automatic
(Auto), Cascade (Cas), and Remote Cascade (RCas)
modes.
The output supports the track algorithm.
The Balance Ramp option is supported.
