4. Sync Input (-2.5 to +2.5 Vdc)
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. Auxiliary Input (-2.5 to +2.5 Vdc)
The Auxiliary input will bias the speed reference directly from an external
device, such as a Woodward Digital Synchronizer and Load Control
(DSLC™).
6. Map Limiter Input
The MAP limiter input limits the amount of fuel using the settings in Service
MENU M**Fuel limiters 2/2**.
The input signal must be an isolated high-quality signal representing the Remote
Speed/Load set point/MAP limit. The Remote Speed/Load set point could be an
operator-adjusted potentiometer, a computer-generated setting, etc.
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
2301D control. This is to prevent isolation problems.
No connection is required to this input if this function is not needed by the
application, set the function to 1 (not used). The 2301D control is designed to
receive either 4–20 mA, 0–5 Vdc, ±2.5 Vdc, or 1–5 Vdc, representing a minimum
Remote Speed/Load set point to a maximum Remote Speed/Load set point.
Separate software minimum and maximum settings are provided for remote
speed (rpm), remote load (kW) and MAP Limit.
When the control is configured as auxiliary input for operation with a DSLC
control, the input is automatically set to accept the ±2.5 Vdc output of the DSLC
control.
Use a shielded twisted-pair cable to connect the Remote Speed/Load set
point/Map limit current transmitter. An input impedance of 250
is present when
the 2301D is configured for a current input. For a voltage input option, the input
impedance will be greater than 10 M
. 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.
Analog Input #1 (Terminals 19-20)
The function of this input is default set for 4 Sync Input with hardware type fixed
±2.5 Vdc.
Selects the function for the analog input:
1 = NOT USED
2 = REMOTE SPEED SETPOINT
3 = BASELOAD SETPOINT (default)
4 = SYNC INPUT
5 = AUXILIARY SPEED SETPOINT
6 = MANIFOLD AIR PRESSURE LIMITER INPUT
