Safety recommendations

• Always turn off the power of the drive machine before you start working.
• Do not expose the equipment to rough handling or heavy impacts.
  • Always read and follow the operating instructions.
  • The tool uses two laser diodes with an output power below 1 mW. Still, never stare directly into the laser transmitter.
  • Calibrate the equipment regularly.
  • Never aim the laser line into someone’s eyes.
  • Opening the housing of the measuring unit may result in hazardous light exposure and voids warranty.
• The equipment should not be used in areas where there is a risk for explosion.
• Do not expose the equipment to high humidity or direct contact with water.
• All repair work should be taken care of by an SKF repair shop.

1.3 Measuring positions

To define the various measuring positions during the alignment procedure we use the analogy of a clock as viewed from behind the Movable machine. The position with the measuring units in an upright position is defined as 12 o’clock while 90° left or right is defined as 9 and 3 o’clock.

3. Instructions for use

3.1 Attach the measuring units

a) Use the fixtures to attach the measuring units to the shafts. Make sure that the unit marked M is attached to the Movable machine and the unit marked S to the Stationary machine (see section 1.2). For shaft with a diameter larger than 150 mm, an accessory extension chain (TMEA C2) is required.

Fig. 8. Attachment of mechanical fixture with chain

If it is not possible to attach the fixtures directly to the shafts (e.g. in case of space problems) the fixtures can be attached to the coupling.

b) Connect the measuring units to the display unit. Make sure that the marking on the cables corresponds to the marking of the ports in the display unit (see fig 6)

3.2 Switch on

Switch on the display unit by pressing the ON/OFF button (see fig. 6). You will now be prompted to enter the machine dimensions as per section 3.4.

3.3 Aim the laser lines

a) Put the two measuring units in the 12 o’clock position with the help of the spirit levels (fig. 4 & fig.7).

b) Aim the laser lines so that they hit in the centre of the target of the opposite measuring unit (fig. 9).

d) If the horizontal alignment is very poor the laser lines might travel outside the detector areas. If this happens a rough alignment must be done. Do this by aiming the laser lines at the positioning detectors in the 9 o’clock position. Turn the measuring units to the 3 o’clock position when the lines will hit outside the detector areas. Adjust the lines to the position half-way between the detector centre and the actual position by means of the adjustment mechanism as per fig. 11. Align the Movable machine until the lines hit the centre of the positioning detector.

3.4 Enter the dimensions

Fig. 12. Entering dimensions screen

Use the tape measure provided to measure the distances indicated on the screen. Navigate to the different distance fields with the left/right selection arrows. Enter the values using the alphanumeric keyboard. The measurement needs to be entered, in millimeter or inches depending on the measurement system used (see section 4, settings). Confirm with OK or with the right selection arrow. Erase the content of a box with the C key.

The rotational speed (RPM, rotation per minute) can be entered directly in the required field. Enter the RPM and press OK to confirm. Otherwise, press OK on the rotational speed field to display the built-in recommended maximum acceptable misalignment table. This table is used (as a reference) for the automatic tolerance check function of the TKSA

40. It is to be used as a guideline only. It shouldn’t replace the original equipment manufacturer recommendations. These recommendations can be entered in the editable fields at the bottom of the table.

Enter the desired values for each field with the alphanumeric keyboard. Confirm by pressing the right/left selection arrow or OK. Highlight the complete line to select it as the reference for the automatic tolerance check function. Press OK to confirm the choice and exit the table.

Next steps: From this module you can navigate to: Measurement module, to measure and determine the misalignment values (“A” distance given mandatory to access this module). See section 3. Soft foot mode, to check the presence of a soft foot on the moveable machine and correct it (only available when all distances are entered). See section 3. Settings menu, to adjust general settings. See section 4 File manager, to display and manage the saved files. See 5

3.5 Measure the alignment

Three measurements are required to evaluate the alignment status. To define the measurement positions, we use the analogy of the clock (see fig.4)

Rotate the shafts to move the measuring units to the 9 o’clock position. Check the positioning of the measuring units with the built in spirit levels (see fig. 7). Confirm the measurement by pressing OK. Leave the measuring units in position whilst the wait and warning symbol is displayed on the screen

Fig. 15 Wait and warning symbol

When registered by the display unit, the measured position is checked on the display.

Fig. 16 9 o’clock measurement position checked

Repeat the same sequence with the measuring units at the 3 o’clock and at 12 o’clock position.

Next steps: Once the last measurement (12 o’clock) is confirmed the result screen is displayed automatically (see section 3.6). Until the last measurement is confirmed, it is still possible to navigate to: Dimension module, to correct the dimensions entered in section 3.4. Settings menu, to adjust general settings (see section 4). File manager, to display and manage the saved files. See 5.

• To modify the dimensions given in the section 3.4 (B, C or motor speed), navigate to the Adding /Modifying dimension icon and press OK.

See below for the procedure to enter or modify a dimension.

• Result screen without a given motor rotational speed If the motor rotational speed is not given, the status of the alignment can not be compared by the unit with the maximum acceptable misalignment value.
• Result screen, with the B and C dimension and / or motor speed not given. If the B and C dimensions are not given in section 3.4, the feet adjustment values can not be calculated by the unit.

See below for the procedure to enter or modify a dimension.

Enter or modify a dimension To get an indication of the alignment status compared with the maximum acceptable misalignment value, the motor rotational speed must be given. Navigate to the adding/modifying dimension icon and press OK. With the selection arrows, navigate to the required rotational speed field. Enter the rotational speed with the help of the alphanumeric keyboard, or press OK to display the recommended maximum acceptable misalignment table (see section 3.4). The display is automatically updated with the status of the alignment compared with the maximum acceptable misalignment value.

To get the feet adjustment values which are needed for the alignment, the B and C dimensions need to be given (see section 3.4). With the selection arrows, navigate to the required fields. Inform the values with the help of the alphanumerical keyboard, and press OK to confirm. To display the feet adjustment values, once all values entered, navigate to the main results icon and press OK.
