The photoelectric sensors may be installed too far apart. Wireless edge triggered more than 3 minutes Check wired input for wiring issue or obstruction. Wireless edge loss of monitoring Check wireless edge inputs. Wireless edge triggered IF an obstruction occurred, no action required. If an obstruction did NOT occur, check inputs and wiring. CLOSE EYE/INTERRUPT triggered, causing IF an obstruction occurred, no action required. If an obstruction did reversal, preventing close, or resetting TTC (main NOT occur, check alignment, inputs, and wiring. board) CLOSE EDGE triggered, causing reversal, IF an obstruction occurred, no action required. If an obstruction did preventing close, or canceling TTC (main board) NOT occur, check alignment, inputs, and wiring. OPEN EYE/EDGE triggered, causing reversal or preventing opening (main board) IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring. CLOSE EYE/INTERRUPT triggered, causing reversal, preventing close, or resetting TTC (expansion board) IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring. CLOSE EYE/EDGE triggered, causing reversal and IF an obstruction occurred, no action required. If an obstruction did preventing close or canceling TTC (expansion NOT occur, check alignment, inputs, and wiring. board) OPEN EYE/EDGE triggered, causing reversal or preventing opening (expansion board) IF an obstruction occurred, no action required. If an obstruction did NOT occur, check alignment, inputs, and wiring. Close input (EYE/EDGE) communication fault from Check inputs and communication method between operators, either other operator wired bus or radio. Ensure operator is powered. May have to erase the wireless communication and reprogram the two operators. Open input (EYE/EDGE) communication fault from Check inputs and communication method between operators, either other operator wired bus or radio. Ensure operator is powered. May have to erase the wireless communication and reprogram the two operators. Close input (EYE/EDGE) communication fault (expansion board) Check the connections between the main board and the expansion board. Open input (EYE/EDGE) communication fault (expansion board) Check the connections between the main board and the expansion board. Force Reversal Look 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. RPM / STALL Reversal Check for obstruction. If no obstruction, check the encoder wiring and that the operator is engaged and free to move. Replace RPM assembly. AC motor no start condition 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. Current Sensor Fault 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.
