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 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.
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.
