4.7.1  Setting collision sensor on and off

The collision sensor can be turned on and off by using 

either the web user interface or the setup panel. Setting 

sensor on and off requires administrator privileges. 

  The collision sensor should be turned off by software when 

there is no collision sensor installed in the system.

Setup panel

Go to the 

Main menu > Robot menu > Coll. sensor menu

 

and turn the control knob on the 

Selection

 to set the sensor 

ON or OFF. Press the 

Save

 button to save the settings.

Web user interface

Go to the 

Welding settings >Welding system > Collision 

sensor settings

 and select the collision sensor on or off by 

clicking the 

ON

 or 

OFF

 button. A pop-up bar with 

Save

 and 

Reset

 

changes

 buttons will appear at the bottom. Press 

the Save button in the dialog to save the settings. When

4.7.2  Selecting sensor type

The sensor type can be selected by using either the web 

user interface or the setup panel. Setting the sensor type 

requires administrator privileges.

Setup panel

Go to the 

Main menu -> Robot menu -> Coll. sensor menu 

and select the switch type by turning the control knob on 

the 

Switch type

 parameter. Press the 

Save

 button to save 

the settings.

Web user interface

Go to the 

Welding settings > Welding system > Collision

 and select the switch type by clicking 

Opening

 or 

Closing

 button. The collision sensor must be 

on in order to change the other settings. A pop-up bar

settings. When turned on, additional settings appear.

4.7.3  Selecting output polarity

The output polarity of the sensor affects to the polarity 

of the signal in the digital robot interface. If the polarity 

is low-active, the signal is 0 on collision and 1 otherwise. 

If the polarity is high-active, the signal is 1 on collision 

and 0 otherwise. Setting the output polarity requires 

administrator privileges.

Setup panel

Go to the 

Main menu > Robot menu > Coll. sensor menu, 

navigate to the 

Output

 parameter and turn the control 

knob on it to change the output polarity. Press the
