Winco DGC-2020 - Manual (Page 113)

Note: ECU Support must be enabled on the Communications, CANbus Setup screen before this alarm
can be configured.
Figure 4-39. Alarms Configuration
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 adjustable from 0 to 150 in 1 s increments.
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 60 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.
Alarm and pre-alarm annunciations for loss of engine speed signals is not user-programmable and
operates as follows. If the MPU (magnetic pickup) or generator frequency is programmed as the sole
engine speed source and that signal source fails, an alarm (and shutdown) is triggered. If the engine
speed source is configured as MPU and generator frequency and a loss of one of the signal sources
occurs, a pre-alarm is annunciated. An alarm (and shutdown) is triggered if both speed signals are lost.
BESTCOMSPlus settings for the sender fail functions (DGC-2020, Alarm Configuration, Sender Fail) are
illustrated in Figure 4-40.
