GHL Profilux - S-Port

[firechild]

I'm trying to utilise one of the S-Ports in a project I'm working on. However, I can't work out how to switch these. My understanding was that S1-4 was controlled by switching channels 1-4 and S5-8 used switching channels 5-8, although in the app, when configuring digital devices it notes S5-8 were outputs 25-48 so perhaps this means switching channels 25-28? If anyone can clarify this, that would be appreciated.
So, I have connected a 6 wire RJ12 cable to S1-4 and used a multimeter to test the switching channels. I have tried switching channels 1-8 and 25-28 manually but I'm not getting any voltage on any of the pins.

I can't find anything in the GHL guides that helps with this. Any guidance with this would be amazing.

The instructions for the breakout box shows the pin out. @Lasse might be able to help you.

What are you going to do with the function? Manage a relay? If i remember right S1-4 was switch channel 1-4 and S5-8 was switch channel 5-8. If you use these S-ports you can`t assign the to power bars and pumps (PAB devices) You need to assign first PB to 5 or above if you only will use S1-4 in your application and to 9 and over if you will use both S ports

As I understand it - You should not activate digital devices in this menu. NO marks here - It should look like below - no activation.

If you activate this S1-8 will act as a ports for digital communication - it was a digital system that was in use before PAB. It works still if you have digital power bars from the stone age and for the old Doser 1. Unactivated - S1- 8 will work for relays and so on. If you have activate this - deactivate and measure again

Thanks. That's what I used to design my PCBs.

I'm connecting to a transistor array instead of relays but the same principles apply.
This was the exact answer I was looking for, thank you. I had the check box ticked for digital device on S1-4 which explains why it was not working. I have unchecked this and things are now working as expected.

Glad that I could help you

I have been using GHL since 2009. First P2, P3 and now P4. One of the good thing with GHL is that they put in a lot of effort to do new equipment backwards compatible. That´s the reason why a configuration that probably 99.9 % of the users do not use still is available for those that still are in the stone age with some of the equipments. I know people that still use these old no PAB digital power bars and old dosers with no problem - both with P3 and P4.

Hi Lasse,

Sorry for resurrecting an old thread, but maybe you can advise me on the best way to achieve something. I'd like to control a device using either analog (1-10v) or digital output but don't know the best one to use. Basically I'd like to base an output on whether conductivity is above or below the nominal value (inc hysteresis).

The purpose is to determine whether a SW or RO water pump should be used for topup. I can accept a digital on/off or an analogue on/off (e.g. 1v for on and 5v for off), but not sure which is easier to setup with GCC and better operationally.

I guess digital output is less likely to be used so the S ports are more likely to be available but on the other hand, a constant analogue voltage (either 1 or 5) would mean I'd have a value 'right now' rather than a digital trigger. I'm thinking that if my controller was powered off for some reason when the digital output is sent it would be missed.

Any advice would be great, thanks!

The easiest way to do this (choosing which pump should react to the level indicator) is probably to use normal switched outlet combined with a PL phrase

Let us say that your salt water pump is connected to outlet 1 and RO water pump to outlet 2. Your level control is Control circuit 1. I would set the control circuit like this. Max on-time is depended of your pumps capacity - you maybe need to adjust that

Now you do some PL - PL 1 in my example for the saltwater pump

This means that if Level 1 say fill and your salinity is below nominal value - this switch is on.

Knit to switch channel 1. If you use S1 to S4 - and control your device with a relay - you cant use a PB here but if you control your pump with a PB outlet - be sure it is assigned to S1

Now we create another PL - PL 2 NOTE the inverted function!

This you knit to switch channel 2 and either use S2 for a relay or S2 assigned to a PB outlet

As normal - Note - I have not tested this but in this configuration S1 should be on if level 1 is active and salinity below your nominal value (increase is activated). If level 1 is active and that salinity is above your nominal value (including hysteresis) (inverted function) S2 will be active instead. If level 1 is not active at all - nothing happens.

You have to test this

Hi Lasse,

Thanks for your extensive response. I don't want to use a switched outlet as the pump power supply is actually shared between 2 pumps (only 1 one on at any time). There are already 12v relays to deal with the switching (hence 1 power supply), I just want the profilux to send a signal (digital) or a constant voltage (analog) based on the actual conductivity vs nominal conductivity.

Thanks and appreciate the input

Use S1-S4 and exclude switch channel 1 to 4 from your power bars. Use the analog S channels. Do not activate digital use of them. You can still use my programming for switch channel 1 and 2 as I understand

Thanks once again Lasse!
