janclaes47 Posted March 23, 2018 Share Posted March 23, 2018 On my pool I have a waterfall , 3 pool led lights, Jacuzzi pump , jacuzzi air blower and 1 jacuzzi led light. Each of these have their own contactor. I can operate them manually or by remote. For remote I have one of these http://www.step1990.com/ผลิตภัณฑ์/wireless-switch/i502l/ From the 4 slots I use only 3. Slot 1 : Jacuzzi pump - jacuzzi air blower and jacuzzi light. Slot 2 : waterfall Slot 4 : Pool lights I can manually operate all items at the same time and there is no problem. If I use the remote and operate any 2 of them in combination the contactors will open after a few seconds. Take note no breaker will open, however each of the items has also it's own breaker and a safety cut of the type below is installed and set to the lowest. Also if start just 1 of the functions, and then press button 3 to which nothing is connected, the contactor will also open. What does this indicate?

Crossy Posted March 23, 2018 Share Posted March 23, 2018 Has it ever worked properly? How long after the control operation does the contactor open? If you temporarily disconnect the contactors and replace with lamps does it work correctly? Link to comment Share on other sites More sharing options...

It indicates that your remote has some strange properties. Using a 'remote' will not be the same as manual activation. When pressing a button on the remote, that button assignment needs to be conveyed to a receiver to actuate its own contactor to simulate a manual button press. How the 'remote' unit conveys two, three or more simultaneous button presses will vary by the design of the remote. You'd need to find out how your 'remote' works. And usually the only way to do that is to take it out of circuit and set up a test circuit and run it through its paces. How many simultaneous buttons can be pressed / what combinations. Length of allowed button press. Response to multiple rapid presses. If the remote is doing analog->digital then transmitting digital 'tokens' over a single radio channel to represent a button press... simultaneous button presses are gonna be confusing. (think about how a TV remote deals or doesn't deal with simultaneous button pressing). Simultaneous actuation of 4 dedicated buttons should be doable. But the remote needs to be designed to do it.

I never tried a lamp, as i don't know which contacts on the contactor to connect it to. It has been like this for long, but if i recall before it only happened if I enabled all 3 functions, now any 2 functions and it happens. If I operate manually, which also engages the contactors, I can run everything at the same time indefinitely. The strange thing is that to port 3 no wire is attached, but if i open any 1 of the functions by remote, then press button 3, the contactor will open after 5 seconds.

Crossy Posted March 23, 2018 Share Posted March 23, 2018 Odd indeed, I was wondering if you had accidentally enabled a one-at-a-time function, but a 5 second delay suggests not. If you can post a photo of the contactor we can say where to connect the lamp. The controller may just be cream-crackered Link to comment Share on other sites More sharing options...

If you click on the link I posted you can see the spec of the remote, and it looks like it should be up for this purpose, as it say up to 8A per circuit.

Crossy Posted March 23, 2018 Share Posted March 23, 2018 I wonder if a brown-out caused by the motors starting is resetting the controller. Time to get out the light bulbs methinks. Contactor coils are on A1 and A2. Link to comment Share on other sites More sharing options...

There is no wire in slot number 3., but if I press button 3 ( even when nothing is running) i hear a remote click somewhere. The system runs over relays Link to comment Share on other sites More sharing options...
RichCor Posted March 23, 2018 Share Posted March 23, 2018 As the remote is designed to be a replacement for 4 standard light switches, it should function fine to engage the latch function of a dedicated relay. If it doesn't hold a relay closed, and subsequently doesn't keep a light bulb lit in a separate test, then time to replace the receiver. Link to comment Share on other sites More sharing options...
janclaes47 Posted March 23, 2018 Author Share Posted March 23, 2018 @Crossy Something else to consider. The whole system is off. I first press button 3 ( you know nothing connected to it). I hear a remote click somewhere, I assume in the remote control unit. Next I press button 1, and it will start up jacuzzi and close down after maybe 2 seconds. I also correct my previous statement that it takes 5 seconds, as it is more like 2. I can press button 1 twice, once to disable and second time to start again, and it will start again and again shut down after 2 seconds. I can do this as many times as i want. Now say I press button 1 and it shuts down after 2 seconds, and I then press button 2 without pressing button 1 first to disable, then nothing will start and i can press as many buttons as i want, nothing will start any more. I have now to cycle power to the control box to enable it again. Link to comment Share on other sites More sharing options...
SomchaiDIY Posted March 23, 2018 Share Posted March 23, 2018 Thai brand Step remote control often make trouble when near load of inductance. Power supply on these is basic with poor filters and often cause damage to microcontroller or damage in program that will not fix itself. Step controller have a reset method to try but I am nearly sure it will not fix this fault. Replace controller will fix problem but need mains filter or use better qualities of remote system. Cheap Step brand is not good for this condition. Regular fault with these controller are -> 1 Many channel operate when one only required 2 Channel turn off after time delay 3 Channel fail to operate Link to comment Share on other sites More sharing options...

Since this has a learning remote, I assume i will have to pair the remote again after reset, and i don't have the manual any more. If i have to replace, what would be a better suited remote system for my application? Link to comment Share on other sites More sharing options...

jacko45k Posted March 24, 2018 Share Posted March 24, 2018 I presume the 3 contactors, which look like relays, have a good solid neutral connection on the coils? This is going to sound like BS, but you have made me think back to a problem I had years ago where an interposing solid state 'relay' fed from a type of remote controller gave me problems. The current draw of the contactor/relay coil, seemed to be insufficient to hold the latch of the remote controller. It was designed for a bit more load. The solution might be to put resistors across each contactor coil. Link to comment Share on other sites More sharing options...

It's actually worse than that, he's got the controller driving relays which then drive the contactor coils. If the reset process doesn't work could try lamps directly on the controller outputs (leave the relays in circuit). Link to comment Share on other sites More sharing options...

Jacko was wondering if the contactor coils were too low a load for the controller, those relays are even lower, that's what I meant by "worse". Hook up 4 lamps (say 40W) directly to the controller outputs, leave the relays connected. See if it makes any difference. If it does we can formulate a solution.

If that is actually the case, and you did it right, there's something very, very wrong. Note that the suggestion to connect to A1 / A2 came before we knew about your relays. Current thinking is lamp on the controller output (to neutral) but leave the relay connected too. Ideally you should try to load up all the outputs but I know you may not have enough lamps for that.

I of course removed the wires that were in A1 and A2, and replaced them by the wires from the lamp. I selected the waterfall contactor. So if I think you suggest to put one wire of the lamp in one of the controller outputs. Where do i get my neutral of the lamp from. Also from the controller?

That explains why the contactor didn't operate! Yes use the common neutral on the controller outputs, which is likely also the controller neutral input. Like Crossy I am a little concerned.

I have to correct my comment. L1 and L2 have constant power. When the contactor engages A1 and A2 as well as T1 and T2 get 220V. But I don't know why contactor doesn't engage when the wires from A1 and A2 are removed. Link to comment Share on other sites More sharing options...

Because they provide the power to the contactor coil. Put it back together, get a beer, call the man who built it for you or a competent sparks.

I connected the lamp to output 2 of the controller < removed the wire that goes to the relay. switch on 2 and lamp lights up. Open the pool lights and lamp goes out, and contactor from pool lights open also after few seconds Link to comment Share on other sites More sharing options...
Crossy Posted March 24, 2018 Share Posted March 24, 2018 Do you have any more lamps? If not, remove the wires from the controller outputs and leave just the lamp. Turn on the lamp using the controller. Press another button. Lamps goes out = faulty controller, not a lot else it can be. Link to comment Share on other sites More sharing options...
