Intended use
The product described is an electronic module that can be used with Hilti impact wrenches of the types SI… …AT­A22 (“…” = 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 particular torque manually on this module!

• Use only Hilti Li­ion 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-wrench sockets described in the operating instructions of the relevant product to tighten Hilti fasteners.

Possible misuse
This product is not suitable for Hilti fasteners in nuclear power plants! For more information contact Hilti Service.

Indicator LEDs
The LEDs on each side of the module indicate the following:

recognized.

•   When tightening, after the impact wrench has switched off auto- matically: the tightening operation was completed successfully.

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 following:

•   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.

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)

Operating modes
The descriptions of the individual operating modes below apply only to the forward rotation of the impact wrench (tightening). In reverse (slackening), the action of the impact wrench is not controlled.

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 is 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.

Parameters in adaptive operating mode

1. Type of threaded fastener (short name for fastener)
2. Material grade/quality
3. Diameter (optional)

The illustration shows the layout of the operating parameters on the display.

Type of threaded fastener
Parameters for various types of threaded fasteners 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 fastener you use.

“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:
The number to the right of the threaded-fastener symbol shows the selected setting.

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 the 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 set 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 set and repeat this test step.

Result 3/3
The fastener was tightened to the specified tightening torque. This stage set is correct for this fastener.

“Unregulated” operating mode
In this operating mode, the adaptive torque module is deactivated. The impact wrench works as though the adaptive torque module was 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.
