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 598)

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.
