Emergency operation of the
reach measurement system
When driving over bumps or foreign bodies in
the reach measurement system, the system
can temporarily lose the current shift position.
If the reach travel position cannot be meas-
ured, the measurement system operates only
in emergency operation.

ger shown in the display
●
The "shift" function is performed at a re-
duced speed
●
The reach carriage moves abruptly into the
end stops
●
The error number
A3421
is shown in the
display
The driver can correct a temporary malfunc-
tion:
●
Re-referencing the reach measurement
system
●
Checking the reach measurement system
for foreign objects
If the malfunction persists after the test, con-
tact your authorised service centre.
Re-referencing the reach measurement
system
A temporary malfunction of the reach meas-
urement system can be corrected by ap-
proaching the reference points of the system.
To do this, the reach carriage must be fully re-
tracted and extended several times.

Fully retract the reach carriage. Extend the
reach carriage again. Retract the reach car-
riage again.
The reach carriage must then be moved gen-
