Nice Robus RB600

[JackX350]

Hi,
I have a Nice Robus RB600, which has proximity / inductive limit switches, controlling opening/closing stop positions. However I cannot get the sliding gate to learn the 'leaf' length - slow down and stop at the mechanical stops.
The problem is that upon opening/closure the gate smashes into the stops, then jumps back - stops, leaving a gap. It is supposed to be possible to eliminate this unwanted function by selection of the LED's - which I have done but the gate still smashes into the stops. The last time it smashed into the opening stop - and kept the motor running - then stopped and has not worked since. I have checked all the fuses - none are blown?
Is this unit supposed to work in this fashion? or does it it have a fault? I would think it should be able to learn the gate 'leaf' length and be able to slow down to rest at the mechanical stops - leaving no gaps and not jumping back?
I would welcome your advice, as to what to do next?
Regards,
Clive

The reed switch is the electronic stop control for the board. I thought the Robus motors had finger switches, but not ruling it out. unplug the reed switches from the board and check them with a multimeter on ohms, both swiitches should be N/C when the gate is midway, ohm meter should read around 2-4ohms? then test again with the magnets next to the reed switch it should read OL on you meter, basically open circuit. Should be 3 wires, they share the GND/common.
I've known NICE boards to fail on the limit switch circuit, this required a new board, FAAC reed switches have a terrible reliability issue, Nice not so much.

Thank you for your prompt post on my Nice Robus RB600. It definitely has proximity switches, one of the reasons I chose this unit. My previous Nice unit had mechanical finger switches, which allowed all kinds of insects, snails etc to enter the unit, plus fine setting was an issue. Many thanks for your advice! I will carry out tests you have kindly advised.
