Instruction manual
The +12Vdc voltage supplied to the pin 1 and 7 of J22 can supply max. 50mA.
Output contacts features:
-
Relay switch OUT 1: Pin 8 and 9. Relay switch OUT 2: Pin 10 and 11.
-
Potential-free contact ratings: 250 Vac, 6 A max resistive load, 3 A max inductive load.

250Vac potential-free contact
- 6A max with resistive load.
- 3A Max with inductive load.
With the factory settings (o1 = 2: NO contact; o2 = 2: NO contact),
L1 is on when there is fault (ex. "bL": blockage due to lack of water).
L2 is on when the pump is running ("Go").
