5.6.1 Important information about collision protection
Intelligent System Protection (ISP)
ISP is a state-of-the-art collision protection system. It substantially reduces crushing hazards.
CAUTION
Danger of pinching/crushing injuries!
•
In spite of the ISP collision protection, there may still be a risk of pinching and crushing in ex-
ceptional cases, since not only the control unit, but also the interaction between the mechanical
and electronic systems is responsible for cutting out the motor! In addition, the mechanical
components, motor and ambient conditions all affect cut-out sensitivity!
•
Therefore, this residual risk cannot be entirely ruled out and the manufacturer may not be held
liable!
The ISP-sensitivity and the ISP-cutoff value depend on the whole system (the mechanical and
electrical components). Please contact your supplier or dealer to determine the ISP capabilities of
a height-adjustable table.
Please note the following for maximizing ISP functionality: In order to ensure the best possible
collision protection, a
mechanical brake
must be built in which activates when the height-
adjustable tabletop moves down.
The cut-out sensitivity may be reduced under a load whenever there is no mechanical brake being
used. However, if there is no load on the tabletop, the ISP collision protection will function prop-
erly even without a brake.
As soon as the ISP has stopped the height-adjustable tabletop, you may then adjust the desktop
only in the opposite direction (the safety feature initially prevents you from adjusting the desk in
the same direction that triggered the ISP)!
The parameters are used to adjust the ISP cut-out level.
Drive back
The "drive back" function is only active if the collision protection (ISP, pinch protection strip) has
been activated.
After a safety function is triggered (by ISP or the pinch protection strip), the tabletop automatically
moves a defined distance in the opposite direction. This immediately eliminates the pinching risk.
