ATR 902 - Internal relays

Post by triujuan »

Good morning,
After a power grid failure, the programmer does not activate the heating elements anymore.
It is as if the internal relays (of the programmer) do not engage.
I have checked the whole installation but I never get voltage on control output 6 & aux 7 when I should.
Is there any way to force (in test mode) the activation of these internal relays?

Thanks in advance.
