Anti-Collision Tm - Linak DESKLINE DL12 User Manual

Anti-Collision™
The function (anti-collision) is an option for the standard CBD4/CBD5/CBD6 advanced/control box software 0077432 version
1.66 and later. A system with anti-collision can limit material damages on a desk if a collision with a solid object should occur.
Enabling the anti-collision
To enable the anti-collision function a little plug called a dongle must be mounted in one of the 2 control ports. The function is
only active when the dongle is mounted. – If you remove the dongle again, you disable the function.
Method of operation
When the DLs/DBs are running the CBD4/CBD5/CBD6 monitors the current consumption on each channel using a special
algorithm. If the current consumption on one channel is increased by more than a predefined slope, a collision is assumed and
all channels are stopped immediately and all DLs/DBs will start to run in the opposite direction (approx. 50 mm). This return
drive is done automatically and continues with or without any control key pressed (for max. 2.5 sec.).
The anti-collision sensitivity is different in upward and downward direction. Upwards the force is approx. 20 kg. Downwards
the load will be approx. 40 kg + the load on the DL/DB (the desk + what is on top of the desk). The 40 kg are needed to
activate the anti-collision function.
Situations where the anti-collision does not work
There are situations where the anti-collision will not be activated. These situations are:
• If the collision happens during the initialisation phase
• If the collision happens within the first 1000 msec or after the control button has been released
• If the collision happens between the floor and the table and the load on the desk + the weight of the legs are lower than 40 kg
• If the collision happens over too long time, e.g. if the collision is with a soft object.
