Add-stage method, Add-stage detection
timing,
Add-stage request
An Add-stage method implements the criteria for adding
another stage. Criteria that may apply are the firing rate of a
stage or stages vs. a threshold, the amount of operating point
versus setpoint error seen by the master, the rate at which
setpoint error is developing, and the rate at which a stage or
stages are approaching their maximum or baseload firing rate.
Typically these use Add-stage detection timing to determine
how long these things have persisted. When all criteria have
been met for a sufficient time, then an Addstage request is
active.
Drop-stage method, Drop-stage detection
timing, Drop-stage request
A Drop-stage method implements the criteria for dropping a
stage. Criteria that may apply are the firing rate of a stage (or
stages) vs. a threshold, the amount of operating point versus
setpoint error seen by the master, the rate at which setpoint
error is developing, and the rate at which a stage or stages are
approaching their minimum firing rate. Typically these use
Drop-stage detection timing to determine how long these
things have persisted. When all criteria have been met for a
sufficient time, then an Drop-stage request is active.

DO NOT CONNECT THE DISPLAY TO TERMINALS 1 2 3.
THIS WILL RENDER THE DISPLAY INOPERABLE.
DISPLAY CAN ALSO BE CONNECTED TO MB2; A, B, C.
FALCON HAS TWO AVAILABLE MODBUS CONNECTIONS:
THIS CONFIGURATION REQUIRES ONE FOR
LEAD LAG COMMUNICATION AND ONE FOR A
SYSTEM DISPLAY.
THERE IS NOT A CONNECTION AVAILABLE FOR A
LOCAL TOUCHSCREEN DISPLAY.
