Manual 02879 723PLUS/Analog Load Sharing
Woodward 79
13. ANALOG OUT 2 shows the value, in mA, of the Analog Output #2 Signal.
This value times 1000 is sent to Modbus. The mA value is prior to the effect
of the offset and span in the I/O CALIBRATION menu.
14. ANALOG OUT 3 shows the value, in mA, of the speed control fuel demand
signal at Analog Output #3. This value times 1000 is sent to Modbus. The
mA value is prior to the calibration effect of the offset and span in the I/O
CALIBRATION menu.
15. ANALOG OUT 4 shows the value, in mA, of the Analog Output #4 Signal.
This value times 1000 is sent to Modbus. The mA value is prior to the
calibration effect of the offset and span in the I/O CALIBRATION menu.
16. LOAD SIGNAL shows the internal voltage output, in Vdc, to the load
sharing bridge.
17. ALARM RESET provides a means of resetting alarm conditions. Toggle
TRUE then FALSE to issue a reset.
Load Control Mode
This menu allows determination of 723PLUS load control mode. This menu can
be very useful for troubleshooting. See Table 6-1 for general mode information.
1. FD DROOP CONTROL—Test mode for setting up fuel demand droop
backup. Load control algorithm will use a scaled representation of the fuel
demand as load feedback.
2. KW DROOP CONTROL—Operating mode when CB AUX contact is open
and kW transducer is active.
3. KW ISOCH LS CONTROL—Normal Isochronous Load Sharing Control
mode.
4. FD ISOCH LS CONTROL—Backup Isochronous Load Sharing Control
mode for use only when the kW transducer fails. Load control algorithm will
use a scaled representation of the fuel demand as load feedback.
5. ISOCH LOADSHARING—Unit has load sharing relay closed and is
performing isochronous load sharing with other units.
6. LOAD RAMP CONTROL—Unit is currently ramping in or out of isochronous
load sharing or baseload mode.
7. BASE LOAD CONTROL—Unit is currently in baseload control mode.
8. REMOTE LOAD ENABLED—Is TRUE when the Remote baseload set
point is active.
9. UNLOADED—Is TRUE when the unit is controlling at the unload trip level.
