After upgrading firmware through BESTCOMSPlus, the checksum failure pre-alarm may trigger. This pre-
alarm is not indicative of an error in this case. It can be cleared by cycling power to the DGC-2020ES. If
the pre-alarm reoccurs, then it is indicative of an error and corrective action should be taken. See
Resetting Alarms, Checksum Failure, below, for more information.
Breaker Close Failure
If enabled, this pre-alarm is triggered when the DGC-2020ES has issued a "breaker close" output and has
not received "breaker closed" feedback from the breaker within the allowed closing time. The Monitor
setting determines whether this condition is monitored only during transitions or always.
Breaker Open Failure
If enabled, this pre-alarm is triggered when the DGC-2020ES has issued a "breaker open" output and has
not received "breaker opened" feedback from the breaker within the allowed closing time. The Monitor
setting determines whether this condition is monitored only during transitions or always.
Reverse Rotation
If enabled, this pre-alarm is triggered when the Generator or Bus rotation is opposite of the Phase
Rotation setting defined on the Rated Data screen.
