Basler Electric DGC-2020 - Manual (Page 257)

Name Description Symbol
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.
SEQSYSTEMSTART When true, this element starts a sequenced system when
no machines are running. This starts the first unit in a
multiple unit system based on the sequencing criterion.
SPEEDLOWER This element lowers the speed setting of the DGC-2020 by
up to 2 rpm per second. After the speed has not been
lowered for 30 seconds, the modified speed is saved to
nonvolatile memory.
SPEEDRAISE This element raises the speed setting of the DGC-2020 by
up to 2 rpm per second. After the speed has not been
raised for 30 seconds, the modified speed is saved to
nonvolatile memory.
SPEEDTRIMINHIBIT When true, this element inhibits operation of the
DGC-2020 speed trim PID controller. For example, speed
trim is not desired in multiple generator systems during
start up synchronization until the generators are stable.
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 ECU, to control the pre start
interval.
STARTOUTPUT This element is used to drive the start output relay from
logic when the Start Output Relay configuration is set to
“Programmable”. When the Start Output Relay
configuration is set to “Programmable”, the start relay will
not close unless logic is used to drive this element. When
the Start Output Relay configuration is set to “Predefined”,
the start relay is closed according to the predefined start
functionality of the DGC-2020. When the “Predefined”
functionality is selected, the relay will not respond to this
element.
