ERROR CODE 02A0
1) SYMPTOM:
a. 02A0 - Encoder error.
2) SOLUTION:
a. Check the connection of the speed sensor cable from the LCB to the speed sensor (Figures A & B).
b. Check the 3 pins of the speed sensor connection for broken or bent pins. Replace the speed sensor if needed.
c. In standby mode, turn the brake to the left release position.
d. Check to see if LED D35 on the LCB is lit when the machine is on standby (Figure A).
- If LED D35 is off, check the LCB. Remove the speed sensor cable from the RPM socket on the LCB, set your multi-meter to DC voltage
and place both terminals on pins 1 & 3 and 2 & 3 of the RPM socket. There should be a reading of about 5V (Figure C).
- If LED D35 is lit, re-install the speed sensor wire. Set your multi-meter to DC voltage, and place the terminals on the pins 1 & 3 and 2 &
4 on the back side of the speed sensor cable. There should be a reading of about 5V (Figure D). if the reading is incorrect, replace the speed
sensor.
e. Check to see if LED D35 on the LCB is flashing while in the unit is in use.
- If LED D35 is not flashing while the unit is in use, replace the speed sensor.
