TROUBLESHOOTING Code 70 71 72 73 74 75 80 81 82 83 84 91 93 95 96 99 Meaning CLOSE EYE/INTERRUPT triggered, causing reversal, preventing close, or resetting TTC CLOSE EDGE triggered, causing reversal, NO preventing close, or canceling TTC OPEN EYE/EDGE triggered, causing reversal or preventing opening CLOSE EYE/INTERRUPT triggered, causing reversal, preventing close, or resetting TTC CLOSE EYE/EDGE triggered, causing reversal and preventing close or canceling TTC OPEN EYE/EDGE triggered, causing reversal or preventing opening 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) Non-monitored device detected on the wireless safety system Force Reversal (Operator 1) RPM / STALL Reversal (Operator 1) AC motor no start condition Current Sensor Fault Normal Operation Solution IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring on main control board IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring on expansion board. 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. Non-monitored contact closure devices are not supported. Make sure connected devices are monitored. Check edges for proper orientation and resistive end cap connection. Check for obstruction. If no obstruction, check that the mechanical assembly is engaged and free to move. See section on Limit and Force Adjustment, and Obstruction Test. Check for obstruction. If no obstruction, check the operator wiring and that the mechanical assembly is engaged and free to move. Replace APE assembly. Motor start sequence failed. If the gate and motor are NOT moving, or moving too slow, check for an obstructed gate, binding in the mechanism, and relay board and start capacitor connections. If the gate and motor ARE moving, failure is due to loss of the encoder signal. Check the encoder cup and sensor on the limit shaft, and wiring. A fault was detected on the current sensor. Make sure the current sensor is connected to the main control board. Check the current sensor harness for an open or short. The operator will need a power cycle to resume operation after correcting the fault. If the fault continues, replace the power board. No action required Saved NO NO YES YES YES YES YES YES YES YES 42
