If the gate opener will not move: (also see “one or both arms are not moving” on next page)
• Check wiring connections.
• Check to be sure safety jumpers are in place .
• If not using slave limit switches, be sure jumpers are in place.
• Be sure the arms are locked and not in manual operation.
• Check the fuse near the power supply—the proper way to inspect a fuse
is to remove it from its clips and check for continuity.
If the gate opener move a few inches or feet and stops or reverses
directions:
• Increase the force setting.
• Check the setback. The setback of the operator is important to correct
operation due to leverage the arm will have on the gate.
The gate does not reach the desired stop points:
• Adjust the limit switches.
• Lengthen the run time parameter.
• Check setback— if setback is incorrect it will limit how far the gate will
move per inch of stroke length.
If the gate will open but will not close:
• If you are not using safety devices the safety jumpers are in place.
• If you are using a safety device:
•Check to make sure you are using the normally closed connection
instead of the normally open.
•Check to be sure there is continuity being provided between the
common and normally closed wire of the safety device. If there is not
continuity then refer to the installation guide of the device to set up
properly.
The display of the board will not light up:
• Check the power supply for 24VAC.
• Check the fuse near the power supply—the proper way to inspect a fuse
is to remove it from its clips and check for continuity.
• The arms are not wired in or properly wired on the limit switch connections.
With out the limit switch connections being closed the board will not light up.
If limit motor is opening or closing past the limits
• Motor must be in slow down mode to detect limits. Check P2 parameter.
The slow down occurs AFTER the number that parameter is set to expires.
Example: If P2 is set to 14 and it takes 13 seconds to move from closed to
open it will not enter slow down mode. Decrease this number.
