The HR 550FS wireless handwheel features a rechargeable battery.
The battery starts charging when you put the handwheel in the
holder.
You can operate the HR 550FS with the battery for up to 8 hours
before it must be recharged again. If not in use, it is recommended
to put the handwheel in the handwheel holder.
As soon as the handwheel is in its holder, it switches internally
to cable operation. This means you can still use it even if the
handwheel is fully discharged. The functions are the same as with
wireless operation.
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.
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 550FS
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.
Caution: Danger to the workpiece and tool!
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. Keep the distance to the
handwheel holder to a minimum. If you do not use
the handwheel, put it in the handwheel holder.
