TROUBLESHOOTING ERROR CODES continued... Some errors are saved in the error code history and some are not. If an error is not saved it will briefly appear on the error code display as it occurs, then disappear. Error Code 66 67 68 69 70 71 72 73 74 75 80 81 82 83 91 93 99 Meaning OPEN EYE/EDGE held more than 3 minutes (expansion board) Wireless edge triggered more than 3 minutes Wireless edge loss of monitoring Wireless edge triggered CLOSE EYE/INTERRUPT triggered, causing reversal, preventing close, or resetting TTC (main board) CLOSE EDGE triggered, causing reversal, preventing close, or cancelling TTC (main board) OPEN EYE/EDGE triggered, causing reversal or preventing opening (main board) CLOSE EYE/INTERRUPT triggered, causing reversal, preventing close, or resetting TTC (expansion board) CLOSE EYE/EDGE triggered, causing reversal and preventing close or cancelling TTC (expansion board) OPEN EYE/EDGE triggered, causing reversal or preventing opening (expansion board) Close input (EYE/EDGE) communication fault from other operator Open input (EYE/EDGE) communication fault from other operator Close input (EYE/EDGE) communication fault (expansion board) Open input (EYE/EDGE) communication fault (expansion board) Force reversal RPM / STALL Reversal Normal Operation Solution Check wired input on expansion board; check for alignment or obstruction. Check wired input for wiring issue or obstruction. Check wireless edge inputs. IF an obstruction occurred, no action required. If an obstruction did NOT occur, check inputs and wiring. IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring. IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring. IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring. IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring. IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring. IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring. Check inputs and communication method between operators, either wired bus or radio. Ensure operator is powered. May have to erase the wireless communication and reprogram the two operators. Check inputs and communication method between operators, either wired bus or radio. Ensure operator is powered. May have to erase the wireless communication and reprogram the two operators. Check the connections between the main board and the expansion board. Check the connections between the main board and the expansion board. Check for obstruction. If no obstruction, check that the operator arm is engaged and free to move. Refer to Limit and Force Adjustment section, and Obstruction Test. Check for obstruction. If no obstruction, check the operator cable wiring and that the operator arm is engaged and free to move. Replace the operator arm if necessary.
