4 112 Gate …
entrance
photocell
has been
blocked for
… hours
Deviation The entrance photocell of a Smart
Selection gate has been blocked
for an abnormally long time. That
probably means that something is
wrong with the photocell
(displaced, covered with manure,
input signal over ALCOM has
ceased, etc.).
- Try to make the photocell work by wiping
away dirt from the photocell eyes.
- Use a long stick or similar to ensure that
there is a straight line of sight between the
photocell eyes. If not, adjust the direction of
the photocell eyes.
The connections inside the EP box on the
gate might be faulty. Contact service
engineer.

4 113 Gate … exit
photocell
probably
detects the
door instead
of cows
Deviation The exit photocell of the Smart
Selection gate probably detects
the gate door as it swings to its
open position. This will have a
negative impact on the cow traffic
through the gate since it makes it
more difficult for cows to pass the
gate.
Adjust the position of the exit photocell of
the Smart Selection gate. Open the gate
door with the joystick, and verify that the
exit photocell is not affected by the gate
door.
