Kromschroeder DG300VC9-6W 75456406 pressure switch adjustment:

1. Begin by disconnecting the system from its electrical power source to ensure safety during maintenance procedures.

2. Remove the housing cover to gain access to the internal components.

3. Utilize an ohmmeter to establish electrical connectivity and measure resistance within the system.

4. Adjust the switching point as necessary by manipulating the hand wheel, allowing for precise calibration.

5. Install a pressure gauge to monitor the system’s pressure levels accurately.

6. Gradually apply pressure to the system while closely observing both the ohmmeter readings and pressure gauge indications. This step allows for real-time monitoring of electrical resistance changes and pressure variations.

7. Fine-tune the switching point by adjusting the hand wheel accordingly, ensuring optimal functionality and performance.

8. Complete the process by securely reattaching the housing cover and restoring the electrical power supply, if required, once all maintenance tasks are completed.
