Name Description Symbol
51-3TRIP
(Optional)
True when the 51-3 overcurrent is in a TRIP condition.
Connect to another logic block input.
59-1TRIP True when the 59-1 overvoltage is in a TRIP condition.
Connect to another logic block input.
59-2TRIP True when the 59-2 overvoltage is in a TRIP condition.
Connect to another logic block input.
78TRIP True when the 78 vector shift is in a TRIP condition.
Connect to another logic block input.
81ROCOFTRIP True when the 81 ROCOF is in a TRIP condition. Connect
to another logic block input.
81TRIP True when the 81 frequency is in a TRIP condition.
Connect to another logic block input.
Other
ALARMSILENCE The alarm will be silenced when this element is true. The
alarm can also be silenced by pressing the Alarm Silence
button on the front panel of the DGC-2020.
ALTFREQOVER When this logic element is true, protection and bus
condition detection is forced to operate at the Alternate
Frequency instead of the Rated Frequency.
ALTVOLTXOVR
(X = 1 to 4)
When this logic element is true and the voltage trim
setpoint source is set for Trim Voltage, the alternate
voltage setting becomes the active set point for the voltage
trim controller.
ATS When this logic element is true, and the DGC-2020 is in
AUTO mode, the generator will run. This can be used in
place of the ATS programmable function if it is desired to
generate the ATS signal as a combination of
programmable logic rather than a simple contact input. If
either the ATS logic element is true or the contact mapped
to the ATS programmable function is true, and the DGC-
2020 is in AUTO mode, the generator will run. If both the
ATS logic element and the ATS programmable function
are false, and the DGC-2020 is in AUTO mode, the
generator will cool down and stop.
