Technical details of the machine 12
6.3 Fuses
Software
To protect the mechanics and the motor, the machine is equipped with an overload
protection. If there is a blockage in the mechanical part, the machine switches off and
the message
Overpump appears on the display.
In this event, it is absolutely necessary to find the root cause of
the blockage and to remove it.
If the root cause is rectified, the machine can be put into operation by confirming with
the
key.
Electrics
The electronic parts and power supply are protected via a micro fuse in the form of a
melting-fuse type (see chapter Delivery: Scope of delivery ). The fuse acts on short-
circuit/over voltage in the power supply and becomes defective after it has fulfilled its
function and can
no longer be used. After the source of the fault has been identified
and rectified, the micro fuse must be replaced.
To do this, the fuse holder is unscrewed, the defective micro fuse is removed and the
fuse holder is inserted again with a new micro fuse (see chapter
Technical Details of
the Machine: Connections and controls on the driving module ). Normally, the
machine can now be restarted.
Never attempt to repair a fuse or bypass - danger to life.
There are two replacement fuses among the components
included in the delivery.
If the newly installed micro fuse breaks immediately, please
contact our Technical Support.
Electronics
If the machine is exposed to an extreme, continuous load due to unfavourable
conditions (high room or outside temperature), a
thermal fuse is activated when a
temperature of the motor of approx. 70 °C is reached. In this case, the machine
switches off to protect against overheating, and the message
T-Error appears on the
display. After a cool-down phase of approx. 15 minutes, the machine can be put into
operation mode again by pressing the
key. For a faster cool-down leave the machine
switched on that the fan accelerates the cool-down phase.
