DGC-2020ES BESTlogic™Plus
Table 13-3 lists the names and descriptions of the elements in the Elements group.
Table 13-3. Elements Group, Names and Descriptions
True when the 27-1 undervoltage is in a TRIP condition.
Connect to another logic block input.
True when the 47 phase imbalance is in a TRIP
condition. Connect to another logic block input.
True when the 50 overcurrent is in a TRIP condition.
Connect to another logic block input.
True when the 59-1 overvoltage is in a TRIP condition.
Connect to another logic block input.
True when the 81 frequency is in a TRIP condition.
Connect to another logic block input.
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-2020ES.
When this logic element is true, protection and bus
condition detection is forced to operate at the Alternate
Frequency instead of the Rated Frequency.
When this logic element is true, and the DGC-2020ES 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-2020ES is in AUTO mode, the generator will
run. If both the ATS logic element and the ATS
programmable function are false, and the DGC-2020ES
is in AUTO mode, the generator will cool down and stop.
When this input is true, and the DGC-2020ES is in OFF
mode, the DGC-2020ES will switch to AUTO mode. This
is a pulsed input. It does not need to be held after the
desired mode switch has occurred.
