6. Remove the 37-pin plug (9) from the control.
7. Plug the adapter cover (10) onto the 37-pin plug of the control.
The adapter cover (10) is equipped with the two lines -W1 and -W2.
8. Connect 37-pin plug (9) to adapter cover (10).
9. Connect plug -X115 of line -W1 to one of the two sensor connections of the tension measuring
device (4).
10. Connect plug -X116 of line -W1 to the POWER connector of the tension measuring
device (4).
11. Connect plug -X117 of cable -W2 to the plug (5) of the sensor (7).
12. Assemble the tension measuring device at the desired position on the table top.
Activating the tension measuring device in the software
1. Set the following parameters via the OP1000 control panel:
• t 08 33 = value 1
Function: Output function of signal Pos1
• t 08 34 = value 20
Function: Length of the signal Pos1
• t 51 53 = value 1
Function: Assign output function to pin 26
• t 51 31 = value 17
Function: Assign input function IN_EXT4 Pin4 (knee switch) (17 = operation lock)
Operating the tension measuring device
For operation of the tension measuring device, see Operating Matrix STITCH.
