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 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 Limit, Speed and Force Adjustment page 23. Check for obstruction. If no obstruction, check the operator wiring and that the mechanical assembly is engaged and free to move. Replace APE assembly. Operator attempted to run, no response from motor drive assembly. Check connector and harness. If connected properly and still not working, replace motor and/or motor drive. Check connections to power board. Power cycle and retry. Replace power board if issue persists. No action required Saved YES YES NO NO NO YES YES YES YES YES YES YES YES 57
