Appendix B. Programmer-Defined Settings
Use the table below to record programmer-defined settings during the generator set controller setup and calibration. The
controller default settings and ranges provide guidelines. The table contains all faults with ranges and time delays including
items that do not have adjustments. Some notices give the programmer a choice to make them active Not adjustable
programmer-defined settings result when the controller logic does not allow changes or the values are engine limited.
SiteTech™ software is required for programming the APM402 controller. Contact your local distributor/dealer for assistance.
Note:
Inhibit time delay is the time delay period after crank disconnect.
Note:
The engine ECM may limit the crank cycle even if the controller is set to a longer time period.
