Chapter 4
For the 5 pt Cal Type, you provide the five RateCal percents between the Low and High
output percentages.
For the advanced cal Type, you provide known flow rates for output percentage setpoints
(Pt2 and Pt4) and the output percentages. This only establishes the rate lookup table for
startup rates.
Input Table
.
The first 5 words of the input table echo the output table, except that the format word is
replaced with a command status that indicates whether a command succeeded or failed.
The next words are the OP% rate of change, the gross weight, rate setpoint, state, version,
and the module status word. There is also a counter which continuously increments.
