Troubleshooting QuickChange™
QuickChange™ is equipped with 3
inductive sensors, one per pin and one
for the locking pistons.
These are monitored continually and
must therefore be engaged in a specific
order. If the order changes a sensor fault
is indicated.
If the lock switch is returned to the closed
position before the system has verified
that the tool is in position, a sensor fault
is indicated. Wait a further half second to
return the switch to the closed position.
All sensor faults are accumulated until
the control system is restarted.
When closing the coupler, the first pin (1)
is engaged, followed by pin (2) and finally
the locking pistons (3)
see figure.
Sensor faults are indicated if the tool is
engaged in the wrong order.
Sensor faults are indicated during oper-
ation if the control system loses contact
with any of the sensors or the CAN bus.
Faults can occur due to three reasons.
1. Sensor fault.
The warning can be acknowledged
with the green function button. Check
whether this is a temporary or a
permanent fault. If the fault remains
after a restart it is a permanent fault.
Contact support.

2. Operation.
See the above
3. CAN bus fault.

The hydraulics in QuickChange™ must
be protected from external damage and
dirt. Do not leave the quick coupler open.
If the locking pistons are retracted when
the base machine/excavator is switched
off, the text ”wedge in wrong position” is
shown during start-up.
Extend the locking pistons, and
QuickChange™ can then be used.
