Programming sensor B2 for clutch-release (P2)
1.
Perform a tightening operation with the tool on the work piece.
2.
Keep the trigger pressed after the tool has shut off and press the Edit button (>2 sec) on sensor B2
until the LED starts to blink. When the button is released the sensor stores the value.
3.
Restore the pressure in the air supply to normal value 6.3 bar.
The sensors are correctly programmed when the B1 sensor lights up if the trigger is pressed and the B2
sensor lights up when the correct tightening torque is achieved and the clutch releases. If needed, perform
a number of test-runs to evaluate the rundown time of the actual screw. The rundown time can be seen in
the TPS controller display and can be used when setting the air option parameters described in Parame-
ters>Air option parameters [Page 000].
When programming of the sensors is done, make sure to connect the magnetic valve to the TPS pneu-
matic system again.
Troubleshooting
If the tightening is rated NOK, one of the error messages in the table below appears in the TPS control
display.
Check that the air option parameters are adjusted in accordance with the actual work piece.
