3C66 MFR lost strip (R <P1> A <P2>)
Unexpected reset point
This alarm is triggered when the
MFR is following a steel strip and
the steel unexpectedly is not
detected anymore, like finding
an actual reset point (gap in the
strip) but at the wrong position.
This can be caused by a wrong
wheel diameter setting (MFR
assumes it has not travelled as
far as it already did).
Or it can happen when the MFR
was put on a wrong position in
the route after other issues
(MFR assumes it follows a
different strip).
MFR lost its path during
following a strip
When following the strip the
MFR responds immediately
when it is not centered on the
strip anymore, this enables the
MFR to react fast enough when
following a bend.
If the sensors are too close to
the strip the MFR will respond
much later.
Also if there is some play in the
chains the response of the MFR
is late.
Slip or sideway force (gravity
when driving on a slope or a
castor wheel not turning freely)
will make matters worse.
Feed caught under the MFR is
also a possible cause.
Troubleshooting
Solution:
Manually reverse the MFR to a
position some distance before
the reset point and resume
route.
Solution:
Manually put the MFR back on
the strip and resume the route.
Check if the MFR is free to turn
left and right, remove feed from
underneath the skirt if present.

Preventive measure:
Ask the Lely Center to make
adjustments.
When an MFR is too late in
slowing down before a reset
point or finds reset points
before expecting it, the wheel
diameter is probably set too high
or the route action is shorter
than the specified length in the
route. Using Auto wheel
diameter is advised but even
then a route can have become
corrupt over time by many
changes and new actions added
with different (often inaccurate
diameters) over time. Adjust the
wheel diameter and increase it
when the MFR is structurally to
late in looking for the reset
points. When it only involves one
action reduce the length of that
action.
Beware: Always write down the
initial values
Preventive measure:
Ask your Lely Center for advice.
While following a strip the MFR
should drive straight, behaviour
like being drunk is an indication
the sensors may need
adjustment or the chains need
tensioning.
