Good to understand in terms of the working of the anti collision sensor is:
- The start up of the lift will trigger some vibration. Therefore the anti collision sensor will start up with one to two sec. delay. Otherwise the startup of the lift will trigger the sensor and the lift would stop every time. This also means that if a user moves the lift bit by bit repeatedly, you could avoid that the anti collision function starts up.
- The anti collision is there for the safety of the machine (lift, screen) It's not for personal safety.
- The anti collision mainly works on pressure and overcurrent (power). Meaning
> If the sensor senses that it needs to work harder (peak in power consumption) it stops.
> If it senses pressure left or right (one of both columns moves out of line) it stops.
- Most important to understand. It detects pressure from hard subjects.
If you put a table under the screen (or whiteboards attached to the screen), it will stop when it senses the pressure from the table.
If you put the same table under the screen, but place a pillow on it, the lift will not sense enough pressure of the pillow. Meaning it will push the pillow down until it senses the resistance / pressure of the table below the pillow. Then it stops.
Users often try to test the system by placing their hand on the top or bottom of the screen, trying to avoid it moving up/down. That is not the right way to test. This way you test the lift on personal safety, not for machine safety.
The sensitivity of the anti collision can be adjusted. Our service teams have dongles that can be connected to the controlbox of the lift to reset the sensitivity.
We know that this is required for installation to different kinds of wall types. A brick wall is sturdy and less sensitive for vibrations than a thin (MDF / Spanplatte) type of wall. Therefore the sensitivity can be changed, based on the wall type
