8 Basic Commissioning Tightening Technology | Bosch Rexroth AG 199/3168.6 Operating the ErgoSpin hand-held nutrunner1 Start switch2 CW/CCW reversal switch3 Tool button4 Socket for the ErgoSpin connection cable8.6.2.1 Nutrunner startThe ErgoSpin is started by actuating the start switch (1) (see Figure 8–23).NotePress the start switch (1) on the hand-held nutrunner and hold until the hand-held nutrunner automaticallyswitches off.Releasing the start switch (1) aborts the tightening process. The aborted tightening process is evaluatedby the tightening controller:– If the torque threshold for play on the start switch (basic setting: 5% of the nominal torque of thehand-held nutrunner) was not exceeded, the tightening is not evaluated. This process is interpretedas “Play on start switch” and ignored (i.e. OK=0 and NOK=0, both LEDs are off).– If the torque threshold was exceeded, the tightening is evaluated as faulty (NOK) and the red LEDsare illuminated (see page 199).8.6.2.2 CW/CCW reversal switchThe direction of rotation for the nutrunner can be changed to tighten and loosen screws. The direction ischanged using the CW/CCW reversal switch (2) on the hand-held nutrunner (see Figure 8–23).The setting for the direction of rotation of the nutrunner is visible on the CW/CCW reversal switch (2).– Switch position towards right : Clockwise rotation, program in accordance with the selected program(basic setting: program 0)– Switch position towards left : Counterclockwise rotation, program 99, cannot be changed.NoteThe direction of rotation for the nutrunner is determined by the algebraic sign for the speed in the tighteningprogram.If you make a change during a tightening sequence, it will only take effect in the next tightening sequence.8.6.2.3 Acknowledging a faulty tightening sequenceIf the PLC assignment table stores the PLC signal NokAck on the tool button (3) (see Figure 8–23),faulty tightenings must be acknowledged by actuating the tool button.A faulty tightening sequence is indicated by illumination of the red LEDs on the hand-held nutrunner.Acknowledgement of a faulty tightening sequence (NokAck) via the tool button is already configured aftercommissioning.NoteAfter the Compact System has been switched on, the tool button must be pressed before you can startthe first tightening.NoteInformation on how to change the function of the tool button (3) using the PLC assignment table (controlsignals) can be found on page 195.System 350 | 3 608 878 040/05.2008
