For S, ST and DS tools, use
parameter T420 Use open end to
activate the open-end
functionality.
For SL and STB tools it is not
possible to change the open-end
parameters in Tools Talk or
Graph. Use Tools Talk Service
to modify open-end settings.
T421 Inverted motor rotation should be checked if an open-end head is used which changes the rotation
direction of the spindle.
If the T421 Inverted motor rotation is set in the wrong way the tool may not operate in a
correct manner and the mechanical stop may be damaged if a tightening is done.
Set T422 Tightening direction to the direction that fits the application and open-end head. “CW” is selected
for right hand threaded fasteners and “CCW” for left hand threaded. This setting is valid for all
programmed Psets.
Parameter P240 Tool tightening direction has no effect when running an open-end tool.
When finished with parameter settings, press Store.
Click open-end tune key in the open-
end parameters section.
Make sure the open-end head can rotate
freely and press the tool trigger.
Open-end tuning measures the gear
ratio and gear play and stores it to the
tool memory.
The old T103 Gear ratio value
will be overwritten.
A confirmation message is displayed if open-end tuning succeeded.
