2.3.4 Fault Warnings and Shutdowns
The controller displays a fault code but the generator set
does not shut down under the high battery voltage (HB)
and low battery voltage (LB) warning conditions shown
in Figure 2-3.
The generator set shuts down automatically under the
conditions listed in F igure 2-4 and the controller
displays a fault code. The generator set cannot be
restarted until the fault condition is corrected and the
controller is reset. See Section 2.3.5 to reset the
controller after a fault shutdown. The controller resets
automatically after a battery voltage fault condition is
corrected.
Shutdown switches on the generator set automatically
reset when the problem is corrected. The high engine
temperature switch automatically resets when the
generator set cools. However, the fault does not clear
until the controller is reset.
Code Fault Description Check
HB High battery
voltage warning
Fault code is displayed if the engine starting
battery voltage rises above 16 VDC for a
12 VDC system or above 30 VDC for a 24 VDC
system for more than 10 seconds when the
engine is not running. This fault condition does
not inhibit engine starting.
The fault condition clears when the battery
voltage returns to a voltage within the limits for
more than 10 seconds.
Check the battery rating and condition.
LB Low battery
voltage warning
Fault code is displayed if the engine starting
battery voltage falls below 9.5 VDC for a 12
VDC system or below 16 VDC for a 24 VDC
system for more than 10 seconds when the
engine is not running. This fault condition does
not inhibit engine starting.
The fault condition clears when the battery
voltage returns to a voltage within the limits for
more than 10 seconds.
Check the battery rating and condition.
Charge or replace the battery.
