Status Meaning
The LEDs flash red. • When scanning: the barcode or
QR code was not recognized.
• When tightening, after the im-
pact 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.
The LEDs flash yellow. Depending on the fastener, the
module has detected the follow-
ing:
• A) The threaded fastener of
the stud 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 T-bolt of the cast-in anchor
channel 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.
