reactivated by the corresponding marker. Note that all areas where the safety level is 
reduced by partly/fully disabled sensors must be protected by optical means or additional 
warning facilities (optical or acoustic). Follow the instructions provided in the operating 
manual. 
 

 

Sensors Off - Right: 

This marker is not included in the Weasel

®

 Starter Kit but is available 

as a special marker. It is used for defining an area where the right sensor pairs are 
disabled. This is useful when Weasels must pass cramped areas. In this case, the distance 
between the middle of the track and an obstacle can be reduced to 25 cm, provided that the 
vehicle is in parallel with the obstacle. Note, however, that in such areas there is the risk of 
collisions with obstacles and accessibility is no longer guaranteed. This marker should only 
be used if there are no other options. The sensors will remain disabled until they are 
reactivated by the corresponding marker. Note that all areas where the safety level is 
reduced by partly/fully disabled sensors must be protected by optical means or additional

This marker is not included in the Weasel

 Starter Kit but is available as 

a special marker. It is used for defining an area where both sensor pairs are disabled, i.e. 

the Weasel will be “blind”. This is useful when Weasels must pass cramped areas. In this 

case, the distance between the middle of the track and obstacle on both sides can be 
reduced to 25 cm, provided that the vehicle is in parallel with the obstacles. Note, however, 
that in such areas there is the risk of collisions with obstacles and accessibility is no longer 
guaranteed. This marker should only be used if there are no other options. The sensors will

Sensors On - All: 

This marker is not included in the Weasel

®

 Starter Kit but is available as 

a special marker. It enables sensors which were disabled before. 
 

2.5  Stations 

 

Stations are locations in the travel path where your Weasels will be loaded (sources) or unloaded (sinks). 
The charging station is an exception. All stations are composed of tracks and markers as described in 
the  previous  sections.  Stations  may  be  simple  stop  points  where  the  goods  are  loaded/unloaded 
manually or areas where loading and unloading transfer stations (available for upgrading your Weasel

®

 

Lite system) are used. Transfer stations will be detailed in chapter 5.  
 
Note each station is always assigned a unique number (1 to 999) which must only be assigned once in 
the travel path. With the Weasel

®

 Lite Starter Kit, you can install 5 stations, for example. If you require 

additional  track  elements  and  markers  you  may  order  them  later  at  any  time.  Typically,  a  tablet  (or 
smartphone) is assigned to a station to enable calling Weasels or instructing Weasels once they reach 
the station.  
 
Although the available track elements and markers enable a great number  of variation options, most 
applications can be implemented following two simple patterns which can be combined to form a travel
