  If your L&J TECHNOLOGIES Switch has power but isn't receiving a signal (indicated by the RED LED being OFF), the receiver might be malfunctioning, requiring factory consultation. Another possibility is incorrect transmitter placement relative to the vessel side, causing out-of-phase reflections. Try moving the transmitter slightly (about +1/2 inch) and connect a voltmeter to the analog output and ground. Adjust the transmitter's position to achieve the maximum voltmeter reading, aiming for 0-10 VDC.

What to do if the external device wired to the relay terminal of my L&J TECHNOLOGIES DELAVAN MICROWAVE 320 Switch isn't working?

  If an external device connected to the relay terminal of your L&J TECHNOLOGIES Switch isn't functioning, but the status LEDs indicate operation, the problem may lie outside the Microwave 320 unit. Check the microwave relay contacts and the external device itself for defects. Ensure power is correctly wired to the relay contacts.
