H
High Coolant Temp: Enable or Disable, threshold is adjustable from 100 to 280°F or 38 to 138°C in 1°
increments. Activation time delay is fixed at 60 s.

Alarms
An alarm is annunciated when a condition programmed to trigger an alarm is detected. When an alarm
condition exists, the front panel Alarm indicator lights, the Horn output (if programmed and enabled)
energizes, and the cause of the alarm is displayed on the front panel LCD. An alarm condition stops the
engine by opening the Fuel output contact. Alarms are reset when the DGC-2020 is set to Off mode.
Each DGC-2020 alarm is described in the following paragraphs. Alarms may be enabled and adjusted in
BESTCOMSPlus or through the front panel HMI.
BESTCOMSPlus alarm settings (DGC-2020, Alarm Configuration, Alarms) are illustrated in
Figure 4-28.
High Coola
nt Temperature
High coolant temperature alarm settings
A
consist of an enable/disable setting and a threshold setting. If
enabled, a high coolant temperature alarm is triggered instantaneously when the engine coolant
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.
