es The HR 550 FS wireless handwheel features a rechargeable battery.
The battery is recharged when you put the handwheel in the holder
(see figure).
You can operate the HR 550 FS with the accumulator for up to 8 hours
before it must be recharged again. It is recommended, however, that
you always put the handwheel in its holder when you are not using it.
As soon as the handwheel is in its holder, it switches internally to
cable operation. In this way you can use the handwheel even if it were
completely discharged. The functions are the same as with wireless
operation.
The transmission range is amply dimensioned. If you should
nevertheless happen to come near the edge of the transmission area,
which is possible with very large machines, the HR 550 FS warns you
in time with a plainly noticeable vibration alarm. If this happens you
must reduce the distance to the handwheel holder, into which the
radio receiver is integrated.
1
When the handwheel is completely discharged, it takes
about 3 hours until it is fully recharged in the handwheel
holder.
Clean the contacts 1 in the handwheel holder and of the
handwheel regularly to ensure their proper functioning.
Caution: Danger to the tool and workpiece!
If interruption-free operation is no longer possible within
the transmission range the TNC automatically triggers an
emergency stop. This can also happen during machining.
Try to stay as close as possible to the handwheel holder
and put the handwheel in its holder when you are not
using it.
