Winco DGC-2020 - Manual (Page 179)

Name Description Symbol
PARTOMAINS Setting this logic element to TRUE indicates to the DGC-2020 that
it is paralleled to a utility.
When paralleled to the utility, the Kw controller will regulate the
machine’s KW output at the Base Load Level (%) that is set on the
Governor Bias Control Settings screen, where the Base Load Level
is in percent of machines rated KW. Otherwise, the KW controller
will implement KW load sharing when part of a load sharing
system. If a load sharing system is not implemented, the speed
controller can be set up to implement speed droop.
When paralleled to the utility, the Var/PF controller will regulate the
machine’s reactive power output according to the control mode
setting. If the control mode is Var Controller, the output will be
regulated to the Kvar Setpoint (%) that is set on the AVR Bias
Control Settings screen, where the Kvar Setpoint (%) is in
percentage of the machines rated Kvar. If the control mode is PF
Control, the reactive power output is regulated to a level that
maintains the machines power factor at the value specified by the
PF setting on the AVR Bias Control Settings screen. When Var/PF
control is not active or not enabled, the voltage controller can be
set up to implement voltage droop.
PRESTARTOUT This element is used to drive the prestart output relay from logic
when the Prestart Output Relay configuration is set to
“Programmable”. When the Prestart Output Relay configuration is
set to “Programmable”, the prestart relay will not close unless logic
is used to drive this element. When the Prestart Output Relay
configuration is set to “Predefined”, the prestart relay is closed
according to the predefined prestart functionality of the DGC-2020.
When the “Predefined” functionality is selected, the relay will not
respond to this element.
RUNINHIBIT When this logic element is TRUE, the DGC-2020 is prevented from
starting and running the generator, regardless of any condition that
would normally cause the generator to run. If this element is false
and there is any condition in effect which will cause the generator
to run, the DGC-2020 will start and run the generator.
RUNMODE When this input is TRUE, and the DGC-2020 is in OFF mode, the
DGC-2020 will switch to RUN mode. This is a pulsed input. It does
not need to be held after the desired mode switch has occurred.
RUNOUTPUT This element is used to drive the run output relay from logic when
the Run Output Relay configuration is set to “Programmable”.
When the Run Output Relay configuration is set to
“Programmable”, the run relay will not close unless logic is used to
drive this element. When the Run Output Relay configuration is set
to “Predefined”, the run relay is closed according to the predefined
run functionality of the DGC-2020. When the “Predefined”
functionality is selected, the relay will not respond to this element.
RUNWLOAD The Start input starts the generator and closes the Gen breaker.
The Stop input stops the generator and opens the Gen breaker.
The DGC-2020 only responds to this logic element when in AUTO
mode.
STARTDELBYP This element allows the Pre Start state to be skipped based on
logic. For example, a start delay may not be necessary when the
engine is warm. This also allows an external device, such as an
ECO, to control the pre start interval.
