Step 4: Set the Stress Vary
Regulate the strain setting on the strain swap to the specified vary. It will decide the strain at which the swap prompts or deactivates the load.
Step 5: Join the Stress Supply
Join the strain supply (e.g., a water pipe, air compressor) to the strain swap’s port. The connection needs to be tight and leak-free.
This is a desk summarizing the wiring connections:
| Terminal | Connection |
|---|---|
| Frequent (C) | Sizzling wire from energy supply |
| Usually Open (NO) | Load terminal |
| Usually Closed (NC) | Load terminal |
| Stress Supply | Stress swap port |
