Gate moves a short distance
and stops:

Gate starts closing then stops &
reopens:

Check that you are out of programming mode, SET light
must be OFF.

Check the battery condition with procedure A: Low
battery voltage condition, later in this section.

Check the motor wires.

If STATUS light flashes 4 times then the operator is in
Multiple Collision Mode. Remove & reapply all power, or
wait 60 seconds to reset operation. If required, check with
procedure B: False collision detection, later in this
section.

If the problem persists, the CP75 main controller might
be faulty.

Check the battery condition with procedure A: Low battery
voltage condition, especially if the STATUS light flashes 3
times.

Motor wires use for the SLAVE operator are too thin.

Check for false collisions with procedure B: False collision
detection, later in this section (STATUS light could also
flash 4 times if the number of detected collisions exceeded
the COLLISION COUNTER feature value).

Intermittent IRB trigger. Check that the voltage applied to
the beams are appropriate.

Spurious trigger. Remote with same coding operated in
area, or intermittent short due to possible moisture on the
FRX or TRG inputs.

If the problem is still not solved, the CP75 main controller
might be faulty.

Check collision sensitivity and other causes with procedure
B: False collision detection.
