8.4 ERROR CODE TROUBLESHOOTING - 01AF
CHAPTER 8: TROUBLESHOOTING
FIGURE A
ERROR CODE 01AF
1) SYMPTOM:
a. 01AF - Electro magnet (ECB) disconnected.
2) SOLUTION:
a. Check the connection of the ECB extension cable from the LCB to the ECB (Figure A).
b. Check to see if LED8 and LED10 on the LCB have a brief light for 3 second when you power on machine.
- If LED8 and LED10 do not have a brief light, replace the LCB.
- If LED8 and LED10 do have a brief light, check the ECB extension cable connection at the LCB (pins 1 & 3 for ECB1, pins 2 & 4 for
ECB2), there should be between 12.8 ~ 14.2 ohms. (Figure B)
- If the ECB resistance is out of the range, replace the ECB.
- If the ECB resistance is within the range, replace the LCB.
b. Check the gap of ECB1 and ECB2 (Figure B). There should be a gap of .5mm between the ECB and the flywheel.
- Adjust the gap as shown in Section 9.16.

8.5 ERROR CODE TROUBLESHOOTING - 02A0
ERROR CODE 02A0
1) SYMPTOM:
a. 02A0 - Encoder error.
b. The unit is in PAUSE Mode at all times.
2) SOLUTION:
a. Check the connection of the speed sensor cable from the LCB to the speed sensor.
b. Check to see if LED D35 on the LCB is on when the brake is turned to the left release position (Figure A).
If LED D35 is off, move the stairs about 3 stairs and check to see if LED D35 is flashing.
- If not, replace the speed sensor.
- If yes, adjust the speed sensor position and clean the speed sensor of any debris (Figures B), then re-test.
