Configurable Elements
Configurable elements are connected to the logic scheme as outputs. The configurable elements are
incorporated into a BESTlogicPlus programmable logic scheme by selecting them from the Elements
group in BESTlogicPlus. For more details, refer to the BESTlogicPlus chapter. Each of the eight elements
can be independently configured to annunciate an alarm or pre-alarm. A user-adjustable time delay can
be set to delay recognition of an element. By default, all elements are configured so that they do not
trigger an alarm or pre-alarm. To make identifying an element easier, each of the elements can be given
a user-assigned name. If used for an alarm or pre-alarm, the user-assigned name appears in the alarm or
pre-alarm annunciation and in the DGC-2020ES event log. Elements can be recognized always or only
while the engine is running. A user-adjustable arming delay disables the configurable element during
engine startup. If the arming delay is set to zero, the configurable element is active at all times, including
when the engine is not running. If the arming delay is set to a non-zero value, the configurable element is
inactive when the engine is not running, and does not become active until after the engine is started and
the arming delay has elapsed. Configurable element status is available in BESTlogicPlus Programmable
Logic when “None” is selected for Alarm Configuration. Configurable element status can be used as logic
inputs to drive other logic in the program, similar to logic control relays.
The BESTCOMSPlus Configurable Elements screen is illustrated in Figure 9-4 and found in the Settings
Explorer under the Programmable Outputs category. If using the front panel, navigate to Settings >
Programmable Outputs > Configurable Elements.
