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