To make identifying the contact inputs easier, a user-assigned name
C
can be given to each input.
Contacts can be recognized
D
always or while the engine is running only.
BESTCOMSPlus settings for the configurable contact inputs (DGC-2020, Programmable Inputs,
Configurable Local Inputs) are illustrated in Figure 4-21.
Figure 4-21. Configurable Inputs Settings
A
Alarm Configuration: None, Prealarm, or Alarm.
B
Activation Delay: Adjustable from 0 to 300 s in 1 s increments.
C
Label Text: An alphanumeric character string with a maximum of 16 characters.
D
Contact Recognition: Always or While Engine Running Only.
Programmable Functions
Any of the 16 contact inputs can be programmed to recognize any one of nine function types:
• Automatic Transfer Switch (ATS)
A
- Disconnect from the mains and start the generator.
• Grounded Delta Override
B
- Uses Grounded Delta sensing if the generator connection is set for Delta.
• Battle Override
C
- The alarms programmed to shut down the unit will be overridden and ignored.
• Low-Line Override
D
- The 51, 27, and 59 settings are scaled by the low-line scale factor setting.
• Single-Phase Override
E
- The unit switches to single phase sensing configuration and uses the
1 Phase Override Sensing setting (A-B or A-C). (Note: Applies only when the Single-Phase
Override (A-C) input is not
invoked.)
• Single-Phase Override (A-C)
F
- The unit switches to single phase A-C sensing configuration
even if the 1 Phase Override Sensing setting is set for A-B. (Note: Applies only when the
Single-Phase Override input is invoked.)
•
Battery Charger Fail
G
- When the selected input is invoked, a user selectable pre-alarm or
alarm is annunciated after the activation delay.
•
Low Coolant Level
H
- When the selected input is invoked, a user selectable pre-alarm or
alarm is annunciated after the activation delay.
•
Fuel Leak Detect
I
- When the selected input is invoked, a user selectable pre-alarm or alarm
is annunciated after the activation delay.
A setting of “None” prevents a function from being triggered by a contact input.
BESTCOMSPlus settings for programmable functions (DGC-2020, Programmable Inputs, Programmable
Functions) are illustrated in
Figure 4-22.
