You arrive at a lift station with a blank HMI screen. What is your next step?

When faced with a blank HMI (Human-Machine Interface) screen at a lift station, it is crucial to communicate effectively with the operations team as your next step. Notifying operations to monitor the system allows them to keep an eye on the functioning of the lift station and ensure that everything is operating normally while you investigate the HMI issue. This collaboration is vital because the operations team can provide immediate feedback or identify problems that may not be visible without the interface.

It's important to ensure the safety and functionality of the system, as a blank HMI can indicate issues that might lead to system failures if not addressed promptly. By alerting operations, you maximize the chances of early detection of any underlying issues and maintain effective operational oversight.

In contrast, turning the HMI off and on may not resolve the root cause of the issue and could potentially lead to data loss or further complications. Engaging with IT at this stage might be appropriate if the problem persists or seems more complex, but the immediate priority is to monitor the system to ensure operational safety. Ignoring the problem is not advisable, as it could have critical implications on lift station operations.
