Parameter 5 

–

 Guard Type Selection 

The  Sentinel  system  has  the  option  of  supporting  light  curtain  optical  protection.  If  light 
curtains  have  been  installed  and  configured  this parameter  is  used to switch  between  the 
planar lasers and the light curtains. The parameter has two options: 

•

 

Planar Laser

. Enables the Lazer Safe LZS-2 optical protection (and disables the light 

curtains). The label “

Planar Laser

” refers to a previous model of laser guards, and is 

maintained for backwards compatibility. 

•

 

Light Curtain

. Enables the OEM light curtain optical protection (and disables laser 

guarding). 

Use the ▲▼ buttons to navigate the options. Changes can be abandoned at any time by 
pressing the 

 button. When the desired option has been selected, press the 

ENTER

 button, 

the value will be written into the Sentinel’s non-volatile memory, and the system will return to 
the parameter list. 

Refer to 

Section 7

 for further details of Light Curtain mode operation.
