commanded.
1.
Check CONN 9 for power when command is given.
2.
Check overload protector
3.
Check PLC output.
4.
Check that safeties are clear, and that IR Beams are aligned.
5.
Check PLC input.
6.
Check the +24VDC at CONN3 pins 8 and 10
Gate operator drives
the gate in the
incorrect direction.
1.
Refer to step 4.10 of Installing and Programming the LXL

Check the quality of the hydraulic fluid. Old fluid will
become sludgy and clogging of internal filter is possible.
MAX Runtime Error
1.
Check for any binding of the gate.
2.
Check for slippage of the drive wheels.
