Sensing system Speed sensor - Short circuit to ground
(K.25.E.95.80 - G.30.B.53)
AFX8010
E0014-04 - Feeder Speed Sensor
Cause:
The feeder RPM sensor (B14) circuit is shorted to ground.
Possible failure modes:
1.
Sensor supply wiring shorted to ground.
2.
Controller internal failure (internal regulator failure).
Solution:
1.
Enter the Universal Display Plus "DIAG" screen. Select the "FEEDER" sort menu, and select "SPD SEN" to
check the voltage range.
The proper voltage sensor blocked by ferrous metal - 5.6 - 7.3 volts
The proper voltage sensor unblocked by ferrous metal - 0.5 - 5.6 volts
The proper voltage sensor when disconnected - 7.3 - 9.0 volts.
A.
If the voltage reading is low (0 - 0.5 volts), continue with Step 2.
B.
If the voltage reading is within the proper limits, continue the troubleshooting at Step 3.
NOTE: Visually inspect the wiring harness and connectors. Verify that the connector was fully installed.
Inspect the terminals and wires at the connector for pushed back or corroded terminals or damaged wires.
Flex the harnesses involved to reveal intermittent breaks or shorts in the wiring concerned.
2.
Disconnect the feeder RPM sensor connector X284.
A.
If the voltage increases to 7.3 - 9.0 volts, the short is in the sensor, or sensor wiring. Replace the sensor.
B.
If the voltage remains low, continue with step 3.
3.
Disconnect the feeder (FE) harness connector X007.
A.
If the voltage increases to 7.3 - 9.0 volts, there is a short to ground in the feeder (FE) harness between
connector X284 and connector X007 wire 489 yellow. Locate the short and repair.
B.
If the voltage remains low, there is a short to ground in the front frame (FF) harness between connector
X007 and connector X020 pin J3-14 wire 489 yellow. Locate the short and repair.
4.
Visually inspect the harness and connectors for damage, bent or dislocated pins, corroded terminals or
broken wires.
A.
If no damage is found, erase the fault code and continue operation.
