02 MPU 1 FAILED (T/F)—A "TRUE" displayed indicates that speed sensor input
#1 (terminals #11 and #12) has failed. A "FALSE" displayed indicates that speed
sensor input #1 is OK.
03 MPU 2 FAILED (T/F)—A "TRUE" displayed indicates that speed sensor input
#2 (terminals #13 and #14) has failed. A "FALSE" displayed indicates that speed
sensor input #2 is OK.
04 REMOTE SPEED FAILED (T/F)—A "TRUE" displayed indicates that the
Remote Speed input (analog input #2) has failed (either below 2 mA or above 22
mA). A "FALSE" displayed indicates that the Remote Speed input is within the
2–22 mA window.
05 TORQUE INPUT FAILED (T/F)—A "TRUE" displayed indicates that the
Torque Signal input (analog input #1) has failed (either below 2 mA [0.5 Vdc] or
above 22 mA [5.5 Vdc]). A "FALSE" displayed indicates that Torque input is
within the correct 2–22 mA or 0.5-5.5 Vdc window.
06 RACK POSN INPUT FAILED (T/F)—A "TRUE" displayed indicates that the
Rack Position Signal input (analog input #3) has failed (either below 2 mA
[0.5 Vdc] or above 22 mA [5.5 Vdc]). A "FALSE" displayed indicates that Rack
Position Signal input is within the correct 2–22 mA or 0.5-5.5 Vdc window.
07 HIGH ACT ALARM (T/F)—A "TRUE" displayed indicates that the Maximum
Fuel Limiter has control of, and is limiting, the actuator driver output. A "FALSE"
displayed indicates that the Maximum Fuel Limiter is not in control of the actuator
driver output.
08 CLON CH1 ERROR (*T/F)— A "TRUE" displayed indicates that a Control
LON Channel 1 error is detected. A "FALSE" displayed indicates Control LON
Channel 1 is functioning properly.
09 CLON CH2 ERROR (*T/F)— A "TRUE" displayed indicates that a Control
LON Channel 2 error is detected. A "FALSE" displayed indicates Control LON
Channel 2 is functioning properly.
10 CLON CH1&2 ERROR (*T/F)— A "TRUE" displayed indicates that both
Control LON Channel 1 and Control LON Channel 2 errors are detected. A
"FALSE" displayed indicates either Control LON Channel 1 or Control LON
Channel 2 is functioning properly.
11 PID @ LOW LEVEL (T/F)—A "TRUE" displayed indicates that a PID @ Low
Level alarm has occurred. A "FALSE" displayed indicates that the PID @ Low
Level alarm has not been detected.
12 HIGH SPEED SW (T/F)—A "TRUE" displayed indicates that the engine speed
has exceeded the 723PLUS Engine Overspeed Trip point. A "FALSE" displayed
indicates that the engine speed has not exceeded the 723PLUS Engine
Overspeed Trip point.
13 CLUTCH FAIL (T/F)—A "TRUE" displayed indicates that a clutch engaged
contact has not been received within the clutch sync time. A "FALSE" displayed
indicates that a clutch engaged contact has been received.
14 TORQ DEVIATION EXCEEDED (T/F)—A "TRUE" displayed indicates that the
torque deviation between the engines has exceeded the maximum deviation for
the specified time limit.
