Two roller shutters on one switch - one goes up, the other every click

Question

Hello, I have this problem I have 6 roller shutters (radio) connected to 3 switches. 2 switches raise and lower the roller shutters without any problem. With one of them I have a problem, the roller shutters go down, but when I want to raise one of them, the other one stops. Only after a few...

The control inputs on SENSO actuators are voltage inputs (i.e. they have a very high input resistance).
The use of long control cables, which are run in parallel with the supply cables, causes a voltage induction in the control cables. In this case, SENSO detects voltage on both control wires and is therefore unable to interpret the signal correctly.
The solution to this problem is to connect ordinary resistors between the control signals (violet and red) and the N wire (f-N and cz-N, not between N and phase as you described). The plug-in location is arbitrary (junction box, switchgear…) .
In this particular case, 240k 2W 500V resistors (e.g. http://www.tme.eu/pl/details/2w-240k-1%25/rez...etalizowane-tht-2w/royal-ohm/mf02sff2403a10/# ) should suffice. If the problem persists you should plug in two such resistors for each direction.

Plug in only the one with the problem and test to eliminate the faulty motor, mechanism, others.

Yesterday, the roller shutter service guys visited and found out that the reason for this was the large distances from the switches to the motors, and they inserted resistors between the N and the phase to help - but they did not help

maybe they are too weak or just the opposite, or the motor is simply hit

At 230V an eleven metre problem? Swap switches, plug in only the faulty one, check the roller shutter circuit directly in the box at the window - you'll eliminate control failure/failure.

I can't check the box at the window because it is plastered over, but when connecting one roller shutter it is better, the roller shutter goes up with almost every click

kindlar · Answer

Can you swap the switch to check?

baxxterhp · Answer

The switch doesn't do anything, I did tests on manually shorting the wires (the switch was also swapped)

. Are these roller shutters radio-controlled or wired? If wired, how is the separation of the motors ensured - relays, special switch?

Krzysztof Kamienski · Answer

The resistors, between the phase and the N . Prima aaaa... Prilis I don't know about your roller shutters, but mine (made in the USA) mainly have problems with limit switches and sometimes a planetary gear made of some miserable cast steel that jams to one side.

baxxterhp · Answer

The roller shutters are radio-controlled, so they can be connected to one switch. However, when one is plugged in, it goes up and down, but when I add a second one, there is a problem

arlix · Answer

If the roller shutter is radio-controlled, the switch is usually battery-powered and transmits the signal to the motor WIRELESS. If you have hard-wired switches there are two possibilities: - the wires from the switch are connected to the radio controller, which establishes communication with the motor. - or, more likely (but it is impossible to check at a distance if this is the case), you have wired controlled motors. In such a case, without a controller/transmitter you cannot connect two roller shutters on an ordinary switch - you will burn out the limiters in the motors. And the symptoms of such a connection are precisely similar to your description. But without more detailed data it is impossible to check this - post pictures of the wiring connection.

baxxterhp · Answer

The motors are mobilus zephir senso

have 5 wires:
1. phase
2. N
3. PE
4 and 5 pulse control via phase

The motors operate normally from the remote control
The switches are ordinary non radio, i.e. phase to switch and short-circuit to control 4 or 5. I emphasise that I have three switches set up in this way, one of which does not work properly (perhaps long cables)
the limiters on these motors are electronic

arlix · Answer

Ok. A little clearer now.
Surely you can eliminate the length of the wires, 11m is no distance for 230V.
The wire from the roller shutter goes to the switch? And how is it powered?
You need to check that the power is fed correctly, maybe there is something wrong there. And it would be good to check the plastered box....
If these two things are ok then, in my opinion, the only thing that remains is a "broken" motor.

Marek J. · Answer

. So each separately behaves correctly? If so it is not the fault of either the distance or the correctness of the connections in the boxes but something with the control modules in the drives. Try using 4 rectifier diodes behind the switch in the conduction direction to the 4 and 5 motors. I'm not sure if it will help, but it's worth a try....
