We have a Orion-Tr 12 | 12 - 30 installed and the way it was setup by the garage is that one cable leaving the H-pin going to the relay of the Cerbo and from there is connected to the ignition so it should activate when the car is turned on.
That does not work right now. The on/off LED will not light up and the battery is not loaded and so far I could not find an error so my question would be if I can just remove the cable from the H-pin to the Cerbo relay and instead connect H and L pin using a switch and activate the booster with that switch? According to the manual (4. Installation)
that should just work fine but the garage guy says it will not work because of the relay (maybe misunderstanding, we are many miles away from each other right now).
Have you tried switching the cerbos relay? Cant see if NO or NC is connected, however, it needs both Ignition and the cerbo relays contact closed in order to enable the orion.
Check the manual, theres five small schematics explaining the H and L pin functions. If not mistaken, +12V on H will enable charging, but engine running detection is still active
Since I am a real noob when it comes to electric installations, I had to read up a bit and as far as I understand, it should be a NO connection, right? So it is open until the signal comes from the ignition and the relay closes and sends the signal via the cable on the NO output.
I will check that at our next stop, of course everything is cramped behind our luggage right now
Your second point means that even if the H pin has a signal, the Orion will check if the engine is running (by checking the voltage)?
I also read that relay 2 in the Cerbo has to be activated manually from the relay menu, I checked using the control panel and the relay 2 is off. Does that mean I need to set it to on so it will trigger or work as expected?
The cerbo relay doesnt react to the ignition. You can program functions for the cerbo relay, but it can also be left manual.
Most likely (just a guesstimation since i got no schematic): 12V comes from the key barrel (?), whenever you got the key turned at least a notch (depends on which signal exactly was used) then goes to the common contact of the cerbo, if realy 1 of the cerbo is activated (looks like NC is connected) then 12V goes to the H pin of the Orion. Whenever one of those, the key or the cerbo relay, is off, then the orion wont have 12V on H pin.
Anyway, you should be able to switch relay 1 trough the cerbos screen.
If you have a schematic of the system, taht would be really helpful.
I was looking at the wrong manual before, i looked at the orion smart manual, but yours got no bluetooth (your link is also the wrong one).
So it should be simpler. 12V on pin H means it enables the charger, also the green LED should then light up. No engine running detection. But the datasheet mentions that they are not meant for battery charging.
Thanks!
I think I have a wrong understanding, I thought the 12V from the key barrel were activating the relay. So in my case, do I need to set the relay 1 to ON in the settings menu so that WHEN 12V are comming from the key they will go to the Orion. And for that scenario, does the Orion be connected to NO? Because NC would get the 12V when the relay is off, or not?
Sadly, I don’t have the schematics, I will ask for them or try to draw the needed parts myself.
And when you say our Orion is not meant for battery charging… what should it charge instead? I am confused…
This model of Orion outputs a fixed voltage, adjustable trough turning the potentiometer next to the terminals. While you can charge a battery with a fixed voltage, its a bit oldschool. Charging trough a multistage algorithm is more efficient and better for the battery. They are intended to run a load directly, so for example a 12V radio in a vehicle with a 24V system.
I think the intention here was, that you can disable the Orion trough the Cerbo. But its relatively easy to test. Activate relay 1 on the cerbo and turn the key, does the Orion turn on? Try again with the relay disabled.
OK, thanks. That makes sense. So basically the whole orion device is just an expensive switch? Or will it balance out different voltages coming from the starter battery?
I took a look and the relay 1 is connected to NC. So it should work when the relay is not activated. But I also noticed in the control panel that the mode is not manual but set to generator which we don’t even have. Does this default to not active or does it not work at all and I need to put it to manual? I am a fan of just trying things out but with electricity in my head everything can burn up anytime haha
P. S. Does the orion has its led green for being on even if no input voltage is coming in? Just to exclude the possibility something in that wiring is wrong.
