Step 4: Set the Strain Vary
Modify the stress setting on the stress change to the specified vary. It will 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 must be tight and leak-free.
Here is a desk summarizing the wiring connections:
| Terminal | Connection |
|---|---|
| Widespread (C) | Scorching wire from energy supply |
| Usually Open (NO) | Load terminal |
| Usually Closed (NC) | Load terminal |
| Strain Supply | Strain change port |
