2301E Digital Control
Woodward
21
The 2301E control is designed to receive either 4
–20 mA, ±2.5 Vdc, or 1–5 Vdc,
representing a minimum Remote Speed/Load setpoint to a maximum Remote
Speed/Load setpoint. Separate software minimum and maximum settings are
provided for remote speed (rpm), remote load (kW) and MAP Limit.
1.
Not Used
2.
Remote Speed Set Point
When the control is in remote droop or isochronous mode the Remote
Speed setpoint moves the Speed Ramp to the same value as the Remote
Speed setpoint,
3.
Baseload Set Point
When the control is in Remote Base Load mode the Remote Load set point
moves the Load Ramp to the same value as the Remote Load set point.
4.
Sync Input (-2.5 to +2.5 Vdc)
—Default setting is 0.7 %/V.
This can be used for a Speed and Phase Matching (SPM) synchronizer
(optional equipment). The Analog Input is configured in the software to
accept a ± 2.5 V signal from a synchronizer. Connect the SPM synchronizer
wires to the Analog Input. Use shielded wire, and connect the shield to
terminal 21 for analog input #1 or to terminal 24 for analog input #2. Make
sure the shield has continuity the entire distance to the SPM synchronizer,
but do not connect the shield to the synchronizer. The shield must be
insulated from all other conducting surfaces.
5.
MAP Limiter Input
The MAP limiter input limits the amount of fuel using the settings in Service
MENU M**Fuel limiters 2/2**.
6.
External Load Sensor Input
This can be used if the load of the generator already has an external load
sensor or watt transducer connected to it.
The input signal must be an isolated high-quality signal representing the Remote
Speed/Load setpoint/MAP limit.
If a pressure transducer is used to give a Limit to the MAP limiter input, make
sure that the pressure sensor is supplied with the same voltage source as the
2301E control. This is to prevent isolation problems.
Use a shielded twisted-pair cable to connect the Remote Speed/Load set
point/Map limit current transmitter. An input impedance of 250 ohm is present
when the 2301E is configured for a current input. For a voltage input option, the
input impedance will be greater than 10 M ohm. This input is not isolated from
the other control inputs and outputs, and an isolation device must be installed if
the transmitter output is not isolated.
