TROUBLESHOOTING
Solution
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 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.
No action required
