8.8 ERROR CODE TROUBLESHOOTING - 02BF
1) SYMPTOM:
a. 02BF - The DC brake is over current or no current.
2) SOLUTION:
a. Check the connection of the brake at the brake extension wire (Figure A) and LCB (Figure B).
b. Check to see if LED12 on the LCB is lit when you run the machine.
- If LED12 is not lit, remove the brake extension wire from the J1 socket on the LCB. Measure the voltage across pin 1 and pin 2 of the
brake cable. If no voltage is present, replace the LCB. If voltage is present, continue to Step C.
c. Take a resistance reading on pin 1 and pin 2 of the DC brake connector (Figure C). The reading should be approximately 52 ohms.
- If the resistance is lower than 52 (or there is no resistance), replace the brake.
- If the brake does not resolve the issue, replace the brake cable.
