Anti-Collision
TM
This function is an option for the standard CBD6S (SMPS) control box.
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 lifting columns are running the CBD6S (SMPS) monitors the current consumption on each channel using a special
algorithm. If the current consumption on one channel is increased more than a predefined slope, a collision is assumed, and
all channels are stopped immediately, and all lifting columns 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. In downward direction the software is less sensitive
and requires a higher load to activate the function. Thus, the Anti-Collision™ is not recommended for applications with light-
weight desks.
The Anti-Collision function is not activated if the collision happens:
• during the initialisation procedure
• within the first second of desk panel activation (ramp-up time) or within the first second after the desk panel
has been released (ramp-down time)
• in downward direction and the load at the point of collision is too low
• over too long time, e.g., if the collision is with a soft object
