Genius Eurobat + 452/455 control board issue
#1
I am an electronics engineer - definitely not an automated gate specialist (but I learn quickly Wink). I have been asked to look at a pair of gates, that have been in place long enough for the installers to have gone out of business. They use the Eurobat 400 SX/DX motor arms, plus a control board which has the legend 452/455 on it. I gather from some internet searches that is probably similar to the FAAC 452MPS board (for which I have the manual).

Both motor arms have virtually removed their fixing/support plates, which started life welded to the (metal) gate posts). The cause appears to be that both motors go on running far too long. If detached from the gate, the actual travel of the arms is around 425mm. This is far in excess of the nominal 400mm, and even further in excess of that given in the Eurobat manual of 390mm. However there appears to be no control over the amount of travel - no limit switches, no "gate is now shut" detection switch - in fact nothing that I would expect as just good engineering practice.

I gather that the motor operation time is programmed into the control board, and that is all there is to stop any motor over-run. Leaving aside its crudity as a control system, what I want to ask is whether the control board can lose its programming? That is exactly what appears to have happened to this particular gate system, given that the arm bracket welds are close to failure and being repaired today.

Presumably the control board relies on EEPROM to store its programmed data? I see no sign of RAM plus backup battery (which might have gone flat).

hi
focus your self on mechanical instalation , be mind this motors dosnt have any microswitch to stop .Mechanical buffer have to be install in the middle of the gate and even mechanical buffers have to be install when the leafe gate reaches the point of opening.

how and where programing data are store - dont know that
