Radio connection
during operation
After installation and during normal operation, the following options of the
handwheel configuration dialog on the control provide information about the
quality of the radio connection:
Data packets
Number of data packets transmitted by radio transmission since the last
activation of the wireless handwheel.
Lost packets – Number
Number of data packets lost since the last activation of the wireless
handwheel. For example, if this value shows that more than two packets are
lost within 10 seconds during radio transmission (wireless handwheel is
outside the handwheel adapter), the limit range has been reached. The radio
connection should be checked. You should change to another radio channel.
Lost packets – Percentage
Percentage of data packets lost since the last activation of the wireless
handwheel.
• Value < 0.05 %
The radio connection functions properly.
• Value between 0.05 % and 0.1 %
The radio connection functions properly, but it is in the limit range. The
radio connection should be checked. You should change to another
radio channel.
• Value > 0.1 %
The radio connection is not reliable. We advise against operating the
wireless handwheel on this channel. The radio connection should be
checked. You must change to another radio channel.
Max. successive lost
Number of data packets that were lost successively, one after the other. If
four successive data packets are lost, an emergency stop is triggered.
• Value = 1
The radio connection functions properly.
• Value = 2
The radio connection functions properly, but it is in the limit range. The
radio connection should be checked. You should change to another
radio channel.
• Value = 3
The radio connection is not reliable. We advise against operating the
wireless handwheel on this channel. The radio connection should be
checked. You must change to another radio channel.
