3.3 Intended use
The product described is an electronic module that can be used with Hilti
impact wrenches of the types SI… …ATA22 ("…" = any character) to tighten
threaded fasteners under controlled conditions, thereby safeguarding the
quality of the bolted connection. A record of the work carried out is saved
in the module and can be read out, for documentation purposes, using the
AT Documentation Software PC application.
It is not possible to set a torque with this module!
• Use only Hilti lithiumion batteries of the B 22 series with this product.
• Use only Hilti-approved battery chargers to charge these batteries. More
information is available from your Hilti Store or from www.hilti.group
• Use only the impact sockets described in the operating instructions of the
relevant product to tighten Hlti fasteners.
3.4 Possible misuse
This product is not suitable for Hilti fasteners in nuclear power plants!
3.5 Indicator LEDs
The LEDs on each side of the module indicate the following:
Status Meaning
The LEDs show green. • When scanning: the barcode or
QR code has been recognized.
• When tightening, after the impact
wrench has switched off auto-
matically: the tightening operation
was completed successfully.

4 English 2124681 *2124681*
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.
The LEDs flash yellow. The module detected that the
threaded fastener had been
tightened and subsequently
slackened. Consequently, the
threaded fastener has been
retightened in accordance with
defined parameters for retightening,
and the tightening operation has
been completed successfully.
3.6 Buzzer
The buzzer in the adaptive torque module emits the following signal tones
as audible feedback:
• Long buzz: Confirmation signal (OK / operation completed successfully)
• 2 short buzzes, the LEDs flash yellow: Warning 1 (OK or, as applicable,
not OK / repeat tightening)
• 4 short buzzes, the LEDs flash red: Warning 2 (not OK / operation aborted)

5.6.1 Adaptive operation
In this operating mode the adaptive torque module regulates the tightening
of the selected type of threaded fastener. The tightening parameters from
the most recently installed software update are used. Product designations
and tightening parameters can change, so it essential to ensure that the
software version installed in the torque module is always up to date.
• When the "Adaptive" operating mode is selected, the impact
wrench's "AT" torque indicator lights up.
• The switch for selecting the operating stage is not active. But you can
use the control switch to turn the impact wrench ON and OFF.
Follow the operating instructions for your impact wrench.

The illustration shows the layout of the operating parameters on the display.
Type of threaded fastener
Parameters for various types of threaded fastener are saved ex-works in the
torque module.
The fastener shown must correspond to the fastener used.
Further information can be found in the quick-start guide of the SI-AT-A22
and in the operating instructions of the product you use.
5.6.2 "Tightening" operating mode
In this operating mode a total of 30 torque settings are available. The setting
to be selected for a particular type of fastener depends on the diameter of
the fastener and the specified torque. The setting has to be determined step
by step on the basis of these data.
For the "Tightening" operating mode, the display shows the following:

10 English 2124681 *2124681*
The number to the right of the threaded-fastener symbol shows the selected
setting.
5.6.2.1 Determining the required setting for the "Tightening" operating
mode
1. ATTENTION: Before starting to tighten a threaded fastener, always
check that the mating faces of the components to be joined are seated
flat against each other and that the nut has been screwed down until it is
seated against the component.
2. Use a low setting for initial tightening of the fastener.
▶Start the step-by-step process with as low a setting as possible, to
avoid the possibility of overtightening and damaging the fastener.
3. Use a calibrated torque wrench to check the torque applied to the fastener.
For repeatable torquing of two or more identical fasteners, make sure
that all torquing conditions remain unchanged. A change in torquing
conditions can necessitate a change to a different stage.
Result 1 / 3
The specified tightening torque of the fastener to be tightened was not
achieved.
▶Back off the fastener and set the torque module to a higher stage.
▶Tighten the fastener with the new stage setting and repeat this test
step.
Result 2 / 3
The specified tightening torque of the fastener to be tightened was
exceeded.
▶Back off the fastener and set the torque module to a lower stage.
▶Tighten the fastener with the new stage setting and repeat this test
step.
Result 3 / 3
The fastener was tightened to the specified tightening torque.
This stage setting is correct for this fastener.
5.6.3 "Unregulated" operating mode
In this operating mode the adaptive torque module is deactivated. The
impact wrench works as though the adaptive torque module were not fitted
to the tool. The adaptive torque module therefore does not have to be
actually removed when it is not needed for short periods of use.
In the "Unregulated" operating mode the display shows the following:

*2124681* 2124681 English 11
In "Unregulated" mode the impact
wrench's "AT" torque indicator
does not light up, but the button
on the impact wrench for selecting
the various stages is operational.
