an open breaker command (if configured). After that the engine stays in its rated speed waiting for
another command.

Local/Remote: When this discrete input is closed, the 2301E-HT controller will only accept Modbus
commands (the analog write Modbus
commands don’t use this logic; there are specific Modbus
addresses to define if a given Modbus analog write is going to be used or not). If this discrete input is
opened, the 2301E-HT
controller will only accept discrete commands. If there isn’t any discrete input
configured for Local/Remote function, then the commands can come either by discrete inputs or by
Modbus commands.

Position/kW Droop: This input is used to switch between valve position or kW droop. When in valve
position droop, the controller will use the gate position feedback as a droop feedback to calculate the
online reference. When in kW droop, this feedback calculation will be done based on the generator
load.
Once one of the above mentioned options is selected, ALL inputs are
active and should be treated as active inputs WHETHER OR NOT
they are wired.
Control Outputs
Actuator Output Analog Outputs
Two analog outputs are available -- Actuator output and Analog #1 output.
The Actuator output can be configured either for 4
–20 mA, 0–20 mA, or for 0–200 mA.
Analog Output #1 is 4
–20 mA only and it is a configurable analog output. This output has the following
options:

Tachometer (Analog Output default)

Gate Position

Gate Limit

Speed Adjustment

Pond/Tail Level

Pond/Tail Level Setpoint

Speed Bias

Generator Power

Actuator output

Baseload Reference
Relay Outputs
Four relay outputs are available. All relay outputs can be used as normally open or normally closed
(configurable).
The first discrete output is Shutdown indication. The others discrete outputs are configurable and the
available configuration is shown below:

Gate Position Switch #1 : This switch can be set to trigger at a specific gate position as the gates go
open or as they close.

Gate Position Switch #2 : This switch can be set to trigger at a specific gate position as the gates go
open or as they close.

Speed Switch #1 : This switch can be set to trigger at a specific % of rated speed as the speed
increases or decreases.

Speed Switch #2 : This switch can be set to trigger at a specific % of rated speed as the speed
increases or decreases.

Speed Switch #3 : This switch can be set to trigger at a specific % of rated speed as the speed
increases or decreases.
