[Urgent] Configuration of programmable relay - Victron MPPT 150-60

Dear support team,

we urgently need your help, in our current project, we are working with Victron MPPT 150-60 model, we need to export a same hardware alarm from the MPPT ( high battery, low battery,...) using the programmable relay .

In the user manual, the programmable relay offre three connections
• NO (Normally Open)
• C (Common)
• NC (Normally Closed

Therefore, i would like to know, if it's possible, can i configure the relay for example to export two-alarm, Between the NO-C contact the High battery alarm, and C-NC contact the Low battery alarm.

Thank you in advance.

One contact is always closed.
NO will be closed if the relay is energised.
NC will be closed if the relay is de-energised.

There is never a circumstance where both will be open. If you wire how you suggest, you will always have one alarm or the other.
