
General Governor Alarm : This relay option closes the relay when an alarm condition is present. All
shutdown conditions are also considered alarms.

Brake Permissive : This relay option closes the relay when the co
ntrol is in the “STOP” mode, the
gates are closed, speed and gate position signals are valid, and the speed is below a configurable
value.

Creep Indication : This relay option closes the relay when creep is detected on the unit. The relay
will stay closed until a configurable time after the unit stops creeping. At that point the relay will open
and the control will continue monitoring the unit for another creep condition.

Speed Bias Enabled : This relay option closes to inform if the Speed Bias signal (either analog or
digital) is enabled and in use at the moment.

Gate Position Signal Failure: This relay option closes when the Gate position signal is enabled and
its input is failed. Input failed means that the current in this input is below 2 mA or above 22 mA.

Level Signal Failure: This relay option closes when the Level signal is enabled and its input is
failed. Input failed means that the current in this input is below 2 mA or above 22 mA.

Remote Signal Failure: This relay option closes when the Remote signal is enabled and its input is
failed. Input failed means that the current in this input is below 2 mA or above 22 mA.

Speed Bias Signal Failure: This relay option closes when the Speed Bias signal is enabled and its
input is failed. Input failed means that the current in this input is below 2 mA or above 22 mA.

Incomplete Start: This relay is closed when a incomplete start is detected. Incomplete Start is
detected when a start command is issued and the turbine speed does not reach a configured value
in a configured time.

Minor gate Position Mismatch: The control continuously compares the actual gate position to the
gate position demand in the control. If they do not match within the “Minor Mismatch Window” for
more than the “Minor Mismatch Delay” time, the control will issue a “Minor Mismatch” alarm.

Overspeed Shutdown : This relay option closes the relay there is an Overspeed Shutdown.

Dirty oil indication: This output will be closed when the discrete input for dirty oil is closed.

Modbus Link Error: This output will be closed when there is an Modbus link error.

Speed Input #1 Fault: This output will be closed when there is a Speed input #1 error.

Speed Input #2 Fault: This output will be closed when there is a Speed input #1 error.

Generator CB_Aux Open Command : This relay option sends a generator opening command if an
unload command is given and the unload conditions are fulfilled in order to open the breaker.

kW Switch #1 : This switch can be set to trigger at a specific kW as the kW increases or decreases.

kW Switch #2 : This switch can be set to trigger at a specific kW as the kW increases or decreases.

Remote Level Reference Signal Failure: This relay option closes when the Remote Level
Reference signal is enabled and its input is failed. Input failed means that the current in this input is
below 2 mA or above 22 mA.
External I/O
The control has the possibility to add one Analog Input/Output LINKnet HT, which adds eight configurable
Analog Inputs and two configurable Analog Outputs. The configuration possi
bilities for these I/O’s are the
same of the analog inputs/outputs that are embedded on the 2301E-HT hardware. This module
communicates with the 2301E-HT hardware through CAN bus. The figures below show the types of
LINKnet HT
modules allowed to work with this 2301E-HT:
