Gate moves a short distance

Gate starts closing then stops &
reopens:
7 Gate overruns its limits:
8 Unreliable auto-close
POSSIBLE CAUSES & SOLUTIONS TO PROBLEM
! Check for false collisions with procedure
collision detection
could also flash 4 times if the number of detected collisions
exceeded the COLLISION COUNTER feature value).
! Intermittent IRB trigger only on closing cycle. Check that
the voltage applied to the beams is appropriate.
! Spurious trigger. Remote with same coding operated in
area, or intermittent short due to possible moisture on the
FRX or TRG inputs. Monitor FRX or TRG LED's.
! If the problem is still not solved, the CP80 main controller
might be faulty.
! Check collision sensitivity and other causes with proce-
dure B: False collision detection.
! Check that the origin marker is correctly positioned as
shown on page 23.
! Check that the ORIGIN sensor wire
plugged
into the CP80 control card, the DOSS sensor
assembly and the magnetic switch assembly (see items 2
and 21 on page 12)
! Check that the respective
clipped
into the housing.
origin was accidentally moved,
! Check if the gate
