TP-6694 7/18 39Section 2 Operation
Common Warning. The fault lamp illuminates yellow
and the alarm horn sounds when the controller is
signaled by a common warning. Use SiteTecht
software to activate the common warning. The local
display shows Common Warng. The common warning
comprises all of the warnings under a single alert.
Critical High Fuel Level (diesel-powered models
only). The fault lamp illuminates yellow and the alarm
horn sounds when the fuel tank level on d iesel models
approaches full. This fault requires an optional critical
high fuel switch and fuel tank for the lamp to function.
The local display shows Fuel Level Critically High.
Default Parameters Loaded. The fault lamp
illuminates yellow and the alarm horn sounds when the
controller detects that the default parameter software
was loaded using SiteTecht software. The local
display shows Default Pars Warning.
ECM Diagnostics (Multiple Engine Inputs). The fault
lamp illuminates yellow and the alarm horn sounds
when ECM diagnostics signals the controller. The local
display shows ECM xxxxx Warning. The specific
display (xxxxx) will be a brief message or fault code that
is engine manufacturer dependent. The engine
literature provides the fault code description and further
information.
Fuel Tank Leak (diesel-powered models only). The
fault lamp illuminates yellow and the alarm horn sounds
when the fuel tank signals a leak of the inner tank. This
fault requires an optional fuel tank leak switch for the
lamp to function. The local display shows Fuel Leak
Warning.
Ground Fault. The fault lamp illuminates yellow and the
alarm horn sounds when a user-supplied ground fault
detector signals the controller. The local display shows
Ground Fault Warning.
High Battery Voltage. The fault lamp illuminates yellow
and the alarm horn sounds when the battery voltage
rises above the preset level for more than 10 seconds.
The local display shows Battery High Warning.
Figure 2-2 shows high battery voltage specifications.
The high battery voltage feature monitors the battery
and battery charging system in the generator set
operating and off modes.

High Coolant Temperature. The fault lamp illuminates
yellow and the alarm horn sounds when the engine
coolant temperature approaches the shutdown range.
The high coolant temperature warning does not function
during the preset inhibit time delay period after startup.
The local display shows Coolnt Temp High Warning.
High Fuel Level (diesel-powered models only). The
fault lamp illuminates yellow and the alarm horn sounds
when the fuel tank level on diesel models approaches
near full. This fault requires an optional high fuel switch
and fuel tank for the lamp to function. The local display
shows Fuel Level High Warning.
Input/Output Communication Loss. The fault lamp
illuminates yellow and the alarm horn sounds when the
controller loses the input/output communication signal
from the optional I/O module board. The local display
shows OB1 Com Loss.
Low Battery Voltage. The fault lamp illuminates yellow
and the alarm horn sounds when the battery voltage
drops below a preset level for more than 90 seconds.
The local display shows Low Battery Warning.See
Figure 2-3 for low battery voltage specifications.

Figure 2-3 Low Battery Voltage Specs
The low battery voltage feature monitors the battery and
battery charging system in the generator set operating
and off modes. The controller logic inhibits the low
battery voltage warning during the crank cycle.
Low Coolant Temperature. The fault lamp illuminates
yellow and the alarm horn sounds when the engine
coolant temperature is low. The low coolant
temperature warning does not function during the preset
inhibit time delay period after startup. The local display
shows Coolant Temp Low Warning.
Low Cranking Voltage. The fault lamp illuminates
yellow and the alarm horn sounds when the battery
voltage drops below 60% of the nominal voltage (12
VDC or 24 VDC) for more than 6 seconds during the
crank cycle. The local display shows Lo Crank Vlt
Warning.
