Re: SCN5 / SCN6 Hardware Thread

I used to have both actuators connected with 2 "laptop" style power supplies some years ago (both 24V, 2A). I have now connected everything using a single power supply (24V, 4.2A, Mean Well SP-100-24, http://www.mouser.com/ProductDetail/Mea ... UI6tv8jA== ).

The electrical circuit is done right, all voltages have been tested and are fine.

What happens is that if one actuator is connected it works ok, starts up and centers itself. If I connect the second one, the actuators don't get detected anymore and I get the message that the ilk was set.

When I increase the voltage from 24 to 24.3-24.4V, both actuators get detected, but can't move - I can tell they don't have enough power because sometimes they move very slow, or just a little, then get stuck -. It is only with a voltage of 26V that both function normally.

Is this normal? :shock:

Tested this with a 13A, 24V power supply, same result.

You can disable the ilk with the tools of the manufacturer or you can decrease the ilk resisitor until it works.
If it says ilk it is your own builded ilk circuit.

I don't think the problem is the ilk. I can connect the ilk to 24V without a resistor and the same happens. I measured the voltage and it is 24V on the ilk wire and to both scn5 wires.

One actuator gets detected at 24V, centered and works fine. When I connect the second one, one actuator gets detected on software startup, then lost when going in the scn5 settings, and the ilk message appears.

I then close and restart the software and get the ilk message again, and of course the actuators don't show in the detection list. Basically the ilk message always appears if the voltage seems to be too low (even though it's 24V).

I then unplug the actuators, plug them back in, close and restart the software, then the ilk message does not show until the same above steps are repeated.

Once I increase the voltage to around 25V, both actuators get detected, but can barely center or move, they don't have enough power and move very slowly or not at all. I never get the the ilk message at this voltage or higher unless I cut the power with the kill switch.

When I raise the voltage to 26V, everything works fine.

26V is a little under the +10% over 24V (they are listed as 24V +/- 10% in the SCN5 specifications).

If they have to run at 26V, any increased risk in destroying them?

hi there i'm very confused about the power supply for the scn5.
after reading this fred i do not know wich one i should order.

i looking for this one: de.mouser.com/Search/m_ProductDetail.aspx?Mean-Well/SP-100-24/&qs=jVZN1Oke4BwXFQUI6tv8jA==
so wich one is recommened and must i order one for both actuators or two for each scn5 ????
thx
regards seppel

As you like but I prefere one power supply for one SCN5.
However, it seems you like to pay much money.

thx for link.
i will go your way with one ps for one actuator.

hi guys,

can someone help me with the plugs for the scn5 actuators. the plugs from mirai are exaggerated expensive! i know that ich can use for the powercabel a 1,5mm² cable and for the datacable a null-modemcable, lan or rs232. but in this case i would have to cut the plug. that is plan b.
i search for the plugs for the scn5 cables.
i an old fred from * scn5-scn6-hardware-thread this guy got this kind of plugs. did anyone got this plugs and make this cables. did anyone know were i can get that stuff?

thx
best regards

Maybe you could show some picture with the plug you need!? That would explain your needs more precise.
