Special features of the HR 550 FS wireless handwheel
1
Due to various potential sources of interference, a 
wireless connection is not as reliable as a cable 
connection. Before you use the wireless handwheel it 
must therefore be checked whether there are any other 
radio users in the surroundings of the machine. This 
inspection for presence of radio frequencies or channels 
is recommended for all industrial radio systems.
When the HR 550 is not needed, always put it in the 
handwheel holder. This way you can ensure that the 
handwheel batteries are always ready for use thanks to 
the contact strip on the rear side of the wireless 
handwheel and the recharge control, and that there is a 
direct contact connection for the emergency stop circuit.
If an error (interruption of the radio connection, poor 
reception quality, defective handwheel component) 
occurs, the handwheel always reacts with an emergency 
stop.
Please read the notes on the configuration of the HR 550 
FS wireless handwheel (see "Configuring the HR 550 FS 
wireless handwheel" on page 613)
Caution: Danger to the operator and machine!
Due to safety reasons you must switch off the wireless 
handwheel and the handwheel holder after an operating 
time of 120 hours at the latest so that the TNC can run a 
functional test when it is restarted!
If you use several machines with wireless handwheels in 
your workshop you have to mark the handwheels and 
holders that belong together so that their respective 
associations are clearly identifiable (e.g. by color stickers 
or numbers). The markings on the wireless handwheel 
and the handwheel holder must be clearly visible to the 
user!
Before every use, make sure that the correct handwheel 
for your machine is active.
