Meaning
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 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.
