Troubleshooting Electromagnet Issues in Gate Lock Systems

Hello,

For some time, the electromagnet in the locker sometimes held the lock, sometimes not, and finally I decided to replace it with a new one. After installation, however, it turns out that the problem still occurs, as if the magnet opening was turned on all the time. Maybe someone has an idea how to fix it?

Maybe the opening system provides some voltage? You should make sure and check it with a voltmeter. If there is no voltage, it is a purely mechanical issue.

In my opinion - just a mechanical matter.
The lock tongue in the gate after closing the gate
it adheres to the lock catch, which prevents the locking latch from latching.
Check if there is a gap between the lock tongue and the lock catch after closing the gate.
The second possibility is internal stresses in the lock, which may occur after tightening the lock to the curve of the base in the post - but this is very unlikely - check if there is "play" between the gate and the catch - after closing.

(Isn`t this a "memory lock"??? Because it changes things a bit, because after one "opening impulse" such a lock remains "open" for a long time until someone opens the gate and closes it again. This is a function used to operate the gate "one person". This means - I am alone at home and to leave, I can unlock the gate with one impulse. No one has to "let me out" - the gate closes and "holds" itself after I leave. But if you let someone in /let him out, and after he entered/exited, you "accidentally" pressed the button after the gate closed - then it turns out that "the lock doesn`t hold". )

Yes, it is a memory lock, but it does not hold even when I open and close it 10 times.

So it looks like it`s a "lack of play" (I`d rather rule out a "manufacturing defect", because the previous lock would have to have the same defect). It`s unlikely. And the "lack of play" could have caused the previous lock to not work properly.

To rule out a manufacturing defect, instead of closing and opening the gate "ten" times, check the lock without closing the gate. If you pull the "catch" of the lock after pressing the button, and the catch always opens only once, it means that the lock is functional, and if it opens more than once - it means that the lock is defective (or voltage is constantly supplied from the intercom) - more there are no options. Just check it out.

Regards.

Thanks for your replies.
The previous lock had the same problem, so I wanted to replace it. It`s actually a good thing that I took it out, because the cables were already scattered on the screws.

Well, it doesn`t open when the gate is open either. Before I connected it to the power supply, it was working for sure.

How should I understand:
Well, it doesn`t open when the gate is open either. Before I connected it to the power supply, it was working for sure.

What does "it doesn`t open either" mean???

If it means that "when the gate is open, it opens and does not hold - it looks like it is getting some voltage - just disconnect both cables, attach them to the gate and check again. If it holds, remove it, connect the cables and see if now it holds - without assembly. If it does not hold, it means that you have voltage from the intercom, i.e. the intercom needs to be replaced (repaired), not the lock.

Yes, what I meant was that he doesn`t keep the "tab" when the gate is open.

So check if it will hold "without cables"

Do you know what a spring looks like? Especially not pushing the pin out? Take it apart and you`ll find out. Either the pin got attached to the coil with crap or the spring pin got lost...

Or maybe one more possibility. There are electric locks with a switch, I call it "day-night". Maybe it`s switched to "day" and the anchor is still released.

I wanted to check the manufacturer`s website for the model I bought, but the packaging doesn`t indicate what it is and there are 10 variants xD. The only thing I found out is that the manufacturer is Orno and it looks like this: http://www.orno.pl/?strona=towary&id_prod=2313&jezyk=pl xD.

Thank you all for your help. The case is already solved. It turned out that when the plate holding the catch was tightened too much, it blocked the latch from closing completely. Thanks again for all the replies.

Good morning

I also have an electric strike on the gate, which sometimes holds and sometimes doesn`t. It is R4 with memory. I checked it by pressing it with my finger - sometimes it is enough to press lightly, sometimes harder, and sometimes it gets stuck and cannot be moved (until, for example, pressing the button on the intercom).
Do you recommend that I replace this electric strike due to mechanical wear or look for the cause in the power supply?

You can hear the sound of the electromagnet working in the handset after pressing the opening button on the intercom. It also happens that the electric strike will not open the door (there is probably a mechanical problem here).



An example of a new electric strike https://www.tim.pl/elektrozaczep-symmetry-z-pamiecia-bez-blokady-uniwersalny-r4-12-30

Please give me some tips.

Just for posterity. I had the same problem - the electric strike did not hold even though there was no voltage. The cause was insufficient movement of the locking element (the catch holding the tongue lock inside). A mechanical and partly electrical problem, because the restriction of movement resulted from a slight expansion of the electromagnet coil, which attracts the internal catch and thus releases the tongue lock. Under normal conditions, this small internal catch is pushed out by a spring after a power failure on the electromagnet. In my case, this element did not have full movement, the coil supported it. I cleaned everything, lubricated and preserved it, slightly sanded the back of the hitch near the axle on which it is mounted - literally 0.5 mm on the edge, polished it, put it back together and it works.

Known memory lock issues.
I once made a memory controller for this in a lock without memory.
Open button controller with activation.
The opening button does not have to be inaccessible - it only works for 2 minutes.

I have a similar problem (I started a thread) - is it possible to disable somehow this memory of the electric door opener ORNO OR-EZ-4033?
The service suggests wrong assembly, but to the question what is the right one he does not answer anymore Besides, it was OK for a few years, only since some time such anomalies. Can the above-mentioned solenoid be taken apart and cleaned and could the coil have swollen here too?
