* Function requires optional input sensors or is engine ECM dependent on some generator set models.
† ECM inputs are engine-manufacturer dependent.
‡ Changeable only by resetting the controller with a personality profile (SiteTech 1.4 or higher).
** Denotes the default parameter range. Typically, ranges for the NiCad battery topology are slightly wider. For more details, refer to the
battery charger operation manual.
