temperature exceeds the threshold setting. The high coolant temperature alarm has an arming delay that
disables the alarm for 60 seconds after engine startup.
Low Oil Pressure
Low oil pressure alarm settings
B
include an enable/disable setting, an arming time delay, and a threshold
setting. If enabled, a low oil pressure alarm is triggered instantaneously when the engine oil pressure
decreases below the threshold setting. The arming time delay disables the low oil pressure alarm function
for a user-adjustable time during engine startup.
Overspeed
Overspeed alarm settings
C
include an enable/disable setting, an activation delay, and a threshold setting.
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
D
consist of an enable/disable setting, an activation delay setting, and a
threshold 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.
Low Coolant Level
Low coolant level alarm settings E consist of an enable/disable setting and a threshold setting. If enabled,
a low coolant level alarm is triggered when the metered coolant drops below the threshold setting.
Figure 4-22. BESTCOMSPlus Alarms Settings
A
High Coolant Temp: Enable or Disable, threshold is adjustable from 100 to 280
°F or 38 to 138°C in 1°
increments. Arming time delay is fixed at 60 s.
B
Low Oil Pressure: Enable or Disable, threshold is adjustable from 3 to 150 psi or 21 to 1,034 kPa in 7
psi or 1 kPa increments. Arming time delay is adjustable from 5 to 15 s in 1 s increments.
C
Overspeed: Enable or Disable, threshold is adjustable from 105 to 140% of the rated engine rpm.
Activation time delay is adjustable from 0 to 500 s in 1 s increments.
D Low Fuel Level: Enable or Disable, threshold is adjustable from 0 to 100% in 1% increments. Activation
time delay is adjustable from 0 to 30 in 1 s increments.
E
Low Coolant Level: Enable or Disable, threshold is adjustable from 1 to 99% in 1% increments.
Sender Fail
The DGC-2020 can be configured to annunciate a pre-alarm or alarm when a loss of signal is detected at
the coolant temperature
A , oil pressure B , or fuel level sender C input. A loss of generator sensing voltage D
(when the DGC-2020 is operating in Run or Auto mode with the ATS closed) can also be configured to
trigger a pre-alarm or alarm. The speed sender fail
E
alarm is always enabled. A user-adjustable time
delay is provided for each sender/sensing alarm/pre-alarm.
