Inputs
Command Inputs
With only one exception, all command inputs have common settings:
1. Start Temp – The set point at which positive demand is calculated.
2. Max Temp – The set point for 100% demand.
3. Over Temp – The set point at which an error is reported due to over
temperature.
An Input demand is calculated as a percentage of error between the Start and
Max Temp set points.
The Exception to the above is when using the J1939 Percent Requested Fan
Speed (SPN 986) message, as an input at which point the demand for the input
(0% to 100%) is determined directly by the ECM.
Command Inputs are selected by entering their code number in the “Bank n
Control n” EE-Memory locations. Each Bank has 3 controls available for
assignment.
The available Command Inputs used to control the fans and their codes are as
follows;
