12.0 RETARD PID SETPOINTS
12.1
Loop Retard Degrees
This user input value is the range of Ignition Timing Retard (in degrees)
represented by the 4-20mA Ignition Retard Output signal. This number should
equal the range of the particular ignition on the engine.
12.2
Timing Advance
This input represents the actual rated engine timing—the most advanced tim-
ing at which the engine is designed to run under normal conditions.
12.3
Reset Rate
Determines the rate at which the program reacts to the output.
12.4
RETOutput
Calculated value of the actual output as the program cycles through the sequence.
12.5
DESOutput
This value represents a total sum of all the active retard offsets.
12.6
Ret-Auto Enable
The retard feature can be controlled manually via the up and down arrows,
adding a unit of travel by each.
12.7
Home Position
Position in degrees to which the timing should revert on startup following an
EPC-250 shutdown reset.
12.8
Timing
Timing value minus offset.
