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 DL/DB’s 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 more than a predefi ned
slope, a collision is assumed and all channels are stopped immediately and all DL/DB’s 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 fi rst 1000 msec or after the control button has been released
• If the collision happens between the fl oor 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.
