main board
During the open cycle the gate will
reverse for 4 seconds, then stop. The
gate will not open.
73
CLOSE EYE/INTERRUPT triggered
on the expansion board
During the close cycle the gate will
stop and reverse to the full open

DIAGNOSTIC CODES
Some codes are saved in the code history and some are not. If a code is not saved it will briefly appear on the display as it occurs, then disappear.
When servicing of the operator is complete, erase the code history by pressing the STOP button until the display flashes “Er” then “CL” (about 6
seconds). When the codes have been erased the display will show “_ _”.
