Meaning
• When scanning: the barcode, QR code or data
matrix code has been recognized.
• When tightening, after the impact wrench
has switched off automatically: the tightening
operation was completed successfully.
• When scanning: the barcode, QR code or data
matrix code has not been recognized.
• When tightening, after the impact wrench
switches off: The threaded fastener could not
be tightened in accordance with the selected
settings. The reason for this could be, for
example, that the impact wrench was switched
off manually before the correct torque was
achieved.
Depending on the fastener, the module has detect-
ed the following:
• A) The threaded fastener of the stud anchor
or the threaded rod with chemical anchor
had already been tightened and subsequently
slackened. Consequently, the threaded fastener
has been retightened in accordance with
the defined parameters for retightening, and
the tightening operation has been completed
successfully.
• B) The threaded fastener for installation systems
and cast-in anchor channels had already been
tightened, but the module is unable to tell
whether the correct tightening torque was
applied. If the threaded fastener was not
tightened with a calibrated torque wrench or
if the indicator LEDs of the module do not
show green, the threaded fastener has to be
checked with a calibrated torque wrench and - if
necessary - tightened to the correct installation
torque.
