CLUTCH SYNC TIME (*0.0–120.0 sec)—Set this value for the time it takes to receive the clutch engaged signal.
UNLOAD RATE (*0.01–100.0%/sec)—Set this value to the desired engine unload rate in percent load per second.
LOAD RATE (*0.01–100.0%/sec)—Set this value to the desired engine load rate in percent load per second.
UNLOAD TRIP POINT (*0.0–100.0%)—Set this value to the desired amount of load on the engine at which the clutch open command (clutch permissive contacts TB#7 and #8 open) will be issued when engine unload has been selected by opening the Clutch Request contact. This is typically set near 0%. GAIN % @ LIGHT LOAD (*10.0–100.0%)—Gain % @ Light Load is the percent of Gain that is required at light loads to maintain stable paralleled engine
operation. This Gain percentage is only active when the engines are paralleled and affects whichever Gain is selected (Gain 1 or Gain 2). This is typically set at 50% and should not need adjusting.
LITE LD GAIN PU (*0.0–101.0%)—Lite Ld Gain PU is the percent of engine load at which the Gain % @ Light Load function becomes active (is turned on). This is typically set at 10% and should not need adjusting.
LITE LD GAIN DO (*0.0–101.0%)—Lite Ld Gain DO is the percent of engine load at which the Gain % @ Light Load function becomes inactive (is turned off). This is typically set at 15% and should not need adjusting.
LOAD SWITCH PU (*0.0–101.0%)—Set this value to the desired engine load that will enable the load switch.
LOAD SWITCH DO (*0.0–101.0%)—Set this value to the desired engine load that will disable the load switch.
CLUTCH IN TIME (*1.0–120.0 sec)—Set this value to the maximum time for the Clutch Permissive Contact to remain closed waiting to receive a Clutch Engaged Contact.
CLUTCH SPEED WINDOW (*0.1–100.0 rpm)—Set this value to the allowable absolute speed difference between the clutched in engine and the engine to be clutched in.
*DISPLAY 2*
ACT SHUTDOWN (T/F)—A “TRUE” displayed indicates that the 723 is asking the actuator driver output to go to the minimum fuel point. A “FALSE” displayed indicates that the 723 is not asking the actuator driver output to go to the
minimum fuel point.
ON DYNAMICS 2 (T/F)—A “TRUE” displayed indicates that dynamics #2 is currently being used. A “FALSE” displayed indicates that dynamics #1 is currently being used.
SPEED CONTROL MODE (T/F)—A “TRUE” displayed indicates that the 723 speed control PID has control of the actuator driver output. A “FALSE” displayed indicates that the 723 speed control PID does not have control of the actuator driver output (something else has control).
ON MAX FUEL LIMIT (T/F)—A “TRUE” displayed indicates that the Maximum Fuel Limiter has control of the actuator driver output. A “FALSE” displayed indicates that the Maximum Fuel Limiter does not have control of the actuator driver output (something else has control).
ON START FUEL LIMIT (T/F)—A “TRUE” displayed indicates that the Start Fuel Limiter has control of the actuator driver output. A “FALSE” displayed indicates that the Start Fuel Limiter does not have control of the actuator driver output (something else has control).
BOOST LIMIT MODE (T/F)—A “TRUE” displayed indicates that the Manifold Air Pressure Limiter input has control of the actuator driver output. A “FALSE” displayed indicates that the Manifold Air Pressure Limiter input does not have control of the actuator driver output (something else has control).
TORQUE LIMIT MODE (T/F)—A “TRUE” displayed indicates that the Torque Fuel Limiter has control of the actuator driver output. A “FALSE” displayed
indicates that the Torque Fuel Limiter does not have control of the actuator driver output (something else has control).
ENGINE OVER SPED? (T/F)—A “TRUE” displayed indicates that the engine has hit the 723 control overspeed trip point. This will be automatically reset each time the engine speed reaches 5% of rated speed during a start, or it can be reset by the software reset found in Service mode, at either headers “MINOR ALARM” or “MAJOR ALARM” at prompt RESET ALL ALARMS.
PORT 2 LINK ERROR (T/F)—A “TRUE” displayed indicates that a communications error has occurred on Port 2.
PORT 3 LINK ERROR (T/F)—A “TRUE” displayed indicates that a communications error has occurred on Port 3.

ENGINE SPEED (0–2000 rpm)—This is the sensed engine speed after it has been processed by the flexible coupling and firing torsional filters.
SPEED REFERENCE (0–2000 rpm)—This is the present value of the engine speed reference.
SPEED REF BIASED (0–2000 rpm)—This is the engine speed reference value plus the bias value from either the load sharing bridge or the AUX input.
ACTUATOR % OUT (0–100%)—This is the actuator output command
percentage to the actuator. This value is the output of the final driver and may be forward (direct) or reverse (indirect) acting. The percentage is proportional to the actuator current (0–200 mA or 0–20 mA).
PERCENT LOAD (0–100%)—This is the calibrated actuator driver signal or (if used and not failed) the Rack Position Input signal after it has been calibrated. The actuator driver signal or the Rack Position Input signal should be calibrated so that at no-load this reads 0%, and at full-load this reads 100%.
REMOTE SPD REF (RPM) (0–2000 rpm)—This is the Remote Speed Setting value from Analog Input #2.
RACK INPUT (mA)—This is the rack position sensor 4–20 mA input (Analog Input #1) signal value, displayed in milliamps.
REMOTE SPD INPUT (mA)—This is the Remote Speed Input (Analog Input #2) signal value, displayed in milliamps.
MANIFOLD PRESS(mA)—This is the Manifold Air Pressure input value from Analog Input #3, displayed in milliamps.
AUX INPUT (Volts)—This is the voltage value seen on the Aux input terminals (Analog Input #4).
TORSIONAL LEVEL—This is the absolute difference (in rpm) between the two MPUs (when used).
