Torque shift Maintenance

< Back To ALIS Manual overview 


Torque shifts and preventive maintenance tasks are planned where there is a need to prove the peak torque that was put on one or more bolts. Because ALIS can connect to an electronic torque wrench, we can read out this peak torque value and attach it to the work report of this maintenance task.

Setting up the hardware - Tochnichi Wrench

Assembling the Torque wrench

  1. Mount the extension bar with the torque wrench with the 1/2" quick lock connection.
  2. Now, mount the iPhone, using the Quadlock mount, by placing the iPhone at 45° against the mount connection, push it slightly towards the mount and rotate it another 45° . Whether the iPhone is used in Portrait or landscape is up to the preference of the user. 

    How to mount the iPhone Case on the Wrench

  3. Clamp the Trimble Location Device on the shoulder or the back of the neck - for best location accuracy *

*The higher the Trimble is mounted the less interference the device has from locating satellites due to blocking of the human body.


Connecting the Wrench to the iPhone

Because the AIRTorque Tohinchi wrench is using the latest bluetooth technology, simply powering ON 

 the wrench will establish the connection with ALIS Personal. ( If the wrench was paired earlier with this iPhone - if not please see ALIS hardware - First time use.) In the connection center under "Device Connections"> "Paired wrench" you can see the status of the connection to the wrench. 

Power will be automatically turned off after 3 minutes without any key operation or any torque load. In case of a "LoBatt" alarm (low battery) condition, it turns off after 1 minute without use.

Assembling the Torque wrench

  1. Mount the extension bar with the torque wrench with the 1/2" quick lock connection.
  2. Now, mount the iPhone, using the Quadlock mount, by placing the iPhone at 45° against the mount connection, push it slightly towards the mount and rotate it another 45° . Whether the iPhone is used in Portrait or landscape is up to the preference of the user.

  3. Clamp the Trimble Location Device on the shoulder or the back of the neck - for best location accuracy *
  1. *The higher the Trimble is mounted the less interference the device has from locating satellites due to blocking of the human body.


Connecting the Wrench to the iPhone

In the connection center under "Device Connections"> "Ingersoll 1:1", the app will search for any PCM modules connected to the network and display them on the screen. Match the IP address of the PCM to the one discovered on the iPhone and select "Join". 

The PCM will automatically connect next time the system is powered on. 

Setting up the hardware - Trimble

Connecting the Trimble to the iPhone

Power ON the Trimble R1 Location Device by pushing the power button until you have 2 green LED's and release the power button  - For more info on the Trimble GPS device please find it in the ALIS Devices Info.  Upon the Blue flashing of the right LED  Open the connection center in your ALIS Personal and go to "Device connections". Under Location Devices you can now tap the connect button - A pop-up will show where, after a few seconds, you can select the Trimble Device ( named "GNSS:xxxxx " ). Make sure you connect to the Trimble device that is paired with this iPhone. If you would need to connect to another Trimble, please view the ALIS hardware - First time use page under Trimble connection. 

The device is now connected and Paired to the iPhone. When the Trimble R1 is running firmware v5.44 or higher the device will automatically reconnect to it's last connected device. If this does not happen, please update your Trimble device.

(info) To shut down the Trimble device Hold down the power button until you have 1 red LED then release the power button . For more info on the Trimble GPS device please find it in the ALIS Devices Info.


Starting the shift

On the Dashboard select the torque shift to start . Scheduled maintenance allows for maintenance to be carried out by more than one technician. Once the desired maintenance session is selected by pressing the start button on the far right

 , the session will start by waiting for the devices to ‘join’. To join a session the technician should have their ALIS Personal app open and connected to the needed devices ( iPad -Trimble and wrench for more info on connections see  ALIS hardware - First time use or Getting started with ALIS on-site ). Each ALIS Personal device will show up as a panel in the torque module.

Here we have 3 devices paired but only 2 are active ( iPhone RED and iPhone SE ) 



*Note: Additional information on the Tohnichi wrench can be found in the wrench’s user manual : http://www.tohnichi.com/pdf/manual-CPT-G.pdf

The most vital information about the maintenance status of the shift and the status of the different iPhones doing the shift is collected in this view. 

  • Battery level of the device - iPhone
  • Current location of the device ( visible on the map indicated by the yellow dot) 
  • Details on the selected asset
  • Name of the corresponding device 
  • Button to identify the right iPhone to the right Panel row  (the background of the ALIS Personal app will flash on the corresponding device) 
  • Button for the technician using the iPad to directly create an observation of the selected asset by the ALIS Personal device

When the shift is started, ALIS Personal will automatically go to the same shift that was activated on the iPad - ALIS Team app.

Starting the work

Each technician is assigned a torque wrench, which is now connected to the ALIS Team - iPad app . They can now observe their position on the map that is active on the iPhone to identify which assets need to be maintained. The color coding is as following:

BLUE = asset to be maintained on shift
GRAY = asset not to be maintained on shift
GREEN = asset maintained during shift
RED (on iPad)  = observation added on this asset 

  1. The technician approaches the asset to be maintained. ALIS personal will automatically identify the asset that needs to be maintained and select it. Depending on the vicinity of other assets, the system can be in three different stages concerning the certainty of the identification of the asset selection toggle button 
    1. The button is GREEN = the system is certain that it has selected the right asset you need to maintain - you can continue without hesitation
    2. The button is Orange = there are one or more assets nearby that could be potential candidates of what you need to maintain - please verify on the map and your location awareness which one you need to maintain - you can toggle the asset selection by pushing on the button. 
    3. The button is Red = the system has not identified any assets in your near vicinity that should be maintained - (info) You can still tap on the asset in the map if you know which asset you need to maintain. 
      A possible reason for the system to not detect the right asset could be  
      1. The GPS location registered in the system for the asset does not correspond with the actual location of the asset.
      2. The GPS device does not have a good satellite reception, which results in a inaccurate location representation on the device. Please see the Trimble information page for more info on the Trimble GPS location device
  2. Upon identification of the asset, proceed to torque the fixing points of the respective asset. The digital reading on the torque wrench will indicate the amount of torque being applied. 

Tohnichi Wrench Users

If using the Tohnichi wrench, Once the appropriate amount of torque has been reached (confirmed by an audio signal from the wrench), release torque tension on the bolt and submit the final torque value to ALIS Personal by pressing the orange ‘Submit’ button located under your right thumb on the wrench . Submission confirmation will be indicated on the iPhone.

Ingersoll Rand Wrench Users

If using the Ingersoll Rand wrench, once the trigger is pulled, the wrench will go to the set torque and will chime when torque has been reached and stop. Trigger should be applied until torque has been reached. The wrench will stop at the desired torque, so the operator does not have to stop the wrench when getting close to the target range.

Readings on the IR wrench will be submitted automatically and the reading will be displayed on the iPhone.


(warning) If there is NO confirmation on the iPhone the value was not registered in the system! Please check your connection to the wrench!
(warning) If the release of the torque tension is not performed, the value will not be submitted. (Tohnichi wrench)
(warning) Should the torque value exceed or be inferior to the predefined torque value (For example* 23Nm +- 15%Nm), the torque wrench will respond with an Error

Successful Torque

registration 1/2 bolts

Successful Torque registration all bolts


Unsuccessful torque

Starting from ALIS Version  2020.02  ( Release  planned for summer 2020 )  with the introduction of the new  Fixation status feature, the input method of Torque maintenance data is updated.
The torque value registration is similar as before Version 2020.02 but allows for the input of 

  • Missing or damaged bolt ( Swipe line to the left of empty bolt value) 
  • Removing incorrect registrations ( Swipe line to the left)
  • Values that are out of tolerance 
  • Manual input of Torque information

Upon submitting the first Torque data submit of the asset , a pop-will appear with a more detailed view of the maintenance action and allowing for the actions described above.
The pop-up can also be accessed by hitting the chevron icon when an asset has been selected with a Torque maintenance task 

Step-by-step guide

To register a missing bolt for this asset

  1. Verify you have the Torque details pop-up open or use the chevron to do so
  2. Swipe the row of the missing bolt the left
  3. A soft swipe will show the missing value button.  Press the button to mark the value missing
  4. A hard swipe will mark the button missing immediately
  5. A note on the the bottom will inform you that you have registered a value out of tolerance.
  6. Once all of the bolts are torqued ( or a manual value is inputted) the data can be saved
  7. If the maintenance action is saved without an entry of all bolts there will be a pop-up to inform you that all no-date bolts will be marked as missing bolts.

Screenshots of the Torque input method


  1. The spinner on the bottom of the app will indicate the amount of bolts that need to be torqued and how much have already been done. Continue to torque and submit the values until all bolts are torqued.

  2. Once all fixing points have been successfully fastened, the technician can now navigate themself to the next asset to be maintained.  The system will start to scan again for new assets nearby to identify.
    1. (warning) If an asset was maintained under the Orange condition ( of the Asset selection toggle button ) and the next asset is in the same area - then this asset needs to be selected manually by tapping on the selection toggle button. 
  3. Once all assets have been maintained, there will be an information message in the "Shift Summary" panel that the shift has been completed. 
  4. The asset indicator on the top right corner of the iPad’s screen will indicate the number of assets that has been successfully completed. Also on the iPad, the shift status will be updated to completed.



(info) Once an asset is validated as maintained, the data will be synched in real-time to the server. When a connection to the server cannot be achieved the data will be stored offline until the connection is restored on the iPhone as on the Ipad 
(info) When multiple iPhones are used simultaneously and remain connected on the WiFi network, they will update the status of the work performed by the other ALIS Personal devices automatically.
(info)At any moment, on the iPad, you can use the 

 button to get an overview of the status of the shift. 

Torque Settings

*The torque setting that is accepted by the iPad / iPhones can be changed in the “Settings” module of the app – which can be found on the left side of the navigation pane.
