RF communication is
partly interrupted.
Distance between base
station and tool is too
great.
If channel 1 is selected, the distance can be up to
30 m. If channel 2 or 3 is selected, the distance
can be up to 10 m.
¾
Move the tool close to the base station to
check whether communication is successful. If
so, increase output power on base station and
on the tool, or move the base station closer to
the tool.
Output power is too
low.
¾
Increase the output power of the base station
and of the tool. If channel 1 is selected, you
can choose up to 25 mW for the output power.
If channel 2 or 3 is selected, you can choose 1
mW for the output power of the base station
and 5 mW for the output power of the tool.
Too much traffic on the
same channel.
¾
Reduce traffic on the wireless network. Deacti-
vate torque plot data transmission.
Too many tools on the
same channel.
¾
Use different channels for different base sta-
tions.
Other 868 MHz devices
on the same frequency.
¾
Use a different channel.
Distance for RF com-
munication is too short
Antenna of the base
station is not tightened
securely.
¾
Manually tighten the base station antenna.
Output power is too
low.
¾
Increase the output power of both the base sta-
tion and the tool.If channel 1 is selected, you
can choose up to 25 mW for the output power.
If channel 2 or 3 is selected, you can choose 1
mW for the output power of base station and 5
mW for the output power of the tool.
Location of the base
station bad.
¾
Move the base station to a location where
there is an unobstructed line of view between
the base station and the tool.
Problem
Possible cause
Action
Barcode scanner on tool
Barcode scanner does
not activate when the
start switch is pressed.
Parameter for Part-ID is
not set to Enable Inter-
locked.
¾
In the
Communication/Part-ID
screen of the
controller, check that the Enable parameter is
set to Enable Interlocked.
Barcode has already
been read.
¾
Activate a further read cycle in the scanner
submenu.
¾
Press the left function key on the tool in order
to activate another read cycle.
Note:
Only available if the parameter for <F1> but-
ton on Tool is set to Read barcode in the
Advanced Application Builder / System Settings
screen of the controller.
