One of the pumps in the DELTAV system did not receive a start signal – how is the 24-volt relay still powered? And why is the relay voltage 20 volts instead of 24 volts? I hope the experts can help! Thank you!

In the future, the topic names should be concise yet still convey the theme; something that doesn’t convey the theme cannot be considered a topic

New points? Was the channel connected to the negative terminal?
