My 3 fuel level sender are resistive senders (0-260 ohms). The potentiometer mobile (float) point is case grounded.
1 I understand I have only to connect B node to pine 20 to D120 ; true ?
2 For the third tank, I will connect B to pin 4 (GP 1) and also to pin 18 (5V) via a 200ohms resistor ; true ?
3 main question ! there is a low level contact on my senders
connecting C point to case (grounded). In previous (old !) installation low level switch on a 12V lamp on panel (each tank have his lamp ). I would enjoy to keep the lamps (incandescents, but can be remove with LED) , a-as a redundant alarm, b- because tanks are really different and D120 offer only one alarm setting for the 3 tanks. Can I ?
