Quattro 10KVA programmble relays not working

I have used Programmable relay assistant to choose Primary, K1 and K2 Relays of the Quattro, in order to drive external load, relays based on DC voltage and SOC value but the relays simply don't seem to have any effect on my external load relays. Can anyone tell me what the issue is over here?
I will attach my setting for primary prog relay below:


Here I want to turn my load on if :

1- Battery Voltage > 48V and

2- Soc > 35%

Does it work AND logic or OR logic?

Select all relay assistants and click on "Summary" and make a screenshot of that.

Depending on how you program them, they can be And Or. The on conditions will always prioritize over off conditions.

In your example above you have set two conditions so it will be Or.

They take some experimenting sometimes to get right.

Sorry I didnt understand "The on conditions will always prioritize over off conditions." Can you elaborate please. Also I have looked all over for any sample article that shows how to use prog relay assistant but havent found any. Can you please share any if you know?

also looking at my current setup, do I need to add a replica of each programmable relay assistant but specify the opposite 'OFF condition' settings? i have currently set al conditions for turning relay ON and assumed if they dont meet then relay turns OFF . am i right? , please correct.

You have defined the conditions for "On".
But you must also define the conditions for "Off
