Overspeed
Overspeed alarm settings include an enable/disable setting, a threshold setting, and an activation delay.
If enabled, an overspeed alarm occurs when the engine speed (in rpm) exceeds the threshold setting for
the duration of the activation time delay.
Low Fuel Level
Low fuel level alarm settings consist of an enable/disable setting, a threshold setting, an activation delay
setting, and a hysteresis setting. If enabled, a low fuel level alarm is triggered when the metered fuel level
drops below the threshold setting for the duration of the activation time delay. The hysteresis setting
functions as an alarm dropout by preventing rapid switching of the alarm annunciation. Once the Low
Fuel Level alarm has activated, it will not turn off until the fuel is increased to a level equal to the
threshold plus the hysteresis setting.
Low Coolant Level
Low coolant level alarm settings consist of an enable/disable setting and a threshold setting. If enabled, a
low coolant level alarm is triggered when the metered coolant level drops below the threshold setting.
ECU Support must be enabled on the Communications, CAN Bus, CAN Bus Setup screen before this
alarm can be configured.
CAN Bus Low Coolant Level
When enabled, any Low Coolant Level indication received over the J1939 CAN Bus it treated as an
alarm. When disabled, Low Coolant Level indications received over the J1939 CAN Bus are treated as
pre-alarms.
Pre-alarms
To configure pre-alarms using BESTCOMSPlus, open the Pre-Alarms screen (Figure 11-2). This screen
is found in the Settings Explorer under the Alarm Configuration category. If using the front panel, navigate
to Settings > Alarm Configuration > Pre-alarms.
The pre-alarm settings are described below.
High Fuel Level
High fuel level pre-alarm settings consist of an enable/disable setting, a threshold setting, an activation
delay setting, and a hysteresis setting. If enabled, a high fuel level pre-alarm is triggered when the
metered fuel level increases above the threshold setting for the duration of the activation delay. The
hysteresis setting functions as a pre-alarm dropout by preventing rapid switching of the alarm
annunciation. Once the High Fuel Level pre-alarm has activated, it will not turn off until the fuel is
decreased to a level equal to the threshold minus the hysteresis setting.
Low Fuel Level
Low fuel level pre-alarm settings consist of an enable/disable setting, a threshold setting, and a hysteresis
setting. If enabled, a low fuel level pre-alarm is triggered when the metered fuel level decreases below the
threshold setting. The hysteresis setting functions as a pre-alarm dropout by preventing rapid switching of
the alarm annunciation. Once the Low Fuel Level pre-alarm has activated, it will not turn off until the fuel
is increased to a level equal to the threshold plus the hysteresis setting.
Low Battery Voltage
Low battery voltage pre-alarm settings consist of an enable/disable setting, a threshold setting, and an
activation delay. If enabled, a low battery voltage pre-alarm is triggered when the battery voltage
decreases below the threshold setting for the duration of the activation time delay. The threshold can be
entered in actual volts or a per-unit value. The per-unit threshold value is based on the nominal battery
voltage setting found on the System Parameters, Rated Data screen.
