Remote Thermocouple Inputs
An optional AEM-2020 (Analog Expansion Module) provides two thermocouple inputs. To make
identifying the thermocouple inputs easier, a user-assigned name
A
can be given to each input.
Select the amount of hysteresis
B
. A user-adjustable arming delay
C
disables thermocouple input
recognition during engine startup.
Each thermocouple input can be independently configured to annunciate an alarm, pre-alarm, or status
only
D
when the thermocouple input signal falls beyond the threshold
E
. A user-adjustable activation delay
F
setting delays alarm annunciation after the threshold has been exceeded.
A remote thermocouple input is disabled when Alarm Configuration is set to “None”. Remote
thermocouple input status is available in BESTlogic+ Programmable Logic when “Status Only” is
selected.
BESTCOMSPlus settings for remote thermocouple inputs (DGC-2020, Programmable Inputs, Remote
Thermocouple Inputs) are illustrated in Figure 4-32. Remote Thermocouple Input #1 is shown.
Figure 4-32. Remote Thermocouple Inputs Settings
A
Label Text: An alphanumeric character string with a maximum of 16 characters.
B
Hysteresis: Adjustable from 0 to 100 percent in increments of 0.1%.
C
Arming Delay: Adjustable from 0 to 300 s in 1 s increments.
D
Alarm Configuration: None, Alarm, Pre-Alarm, or Status Only.
E
Threshold: 32 to 2,507
F in 1F increments or 0 to 1,375C in 1C increments.
F
Activation Delay: Adjustable from 0 to 300 s in 1 s increments.
PROGRAMMABLE OUTPUTS
DGC-2020 programmable outputs include four user-programmable contact outputs if the style number is
xxAxxxxxx. If the style number is xxBxxxxxx, twelve contact outputs are provided. An additional 24
contact outputs are provided with an optional CEM-2020 (Contact Expansion Module).
Contact Outputs
To make identifying the contact outputs easier, each of the contact outputs can be given a user-assigned
name
A
.
BESTCOMSPlus settings for contact outputs (DGC-2020, Programmable Outputs, Contact Outputs) are
illustrated in Figure 4-33.
