PanelView 550 Startup Failure

If your PanelView 550 fails to startup properly, always check the power supply first. Ensure the terminal is receiving the correct voltage and that the wiring and connections to the power source are valid. In addition, you should also ensure the DC power positive and negative are attached to the proper terminals.

PanelView 550 Status Indicators

The status indicators are located on the back of your PanelView 550 terminal. The COMM indicator is green and reflects communication. The FAULT indicator is red and reflects hardware faults. Upon startup, the fault indicator should be off and the comm indicator on. If the fault indicator flashes a few times at startup, this is not a concern. However, if both indicators are off you should check the power cable. See the table below to interpret the terminal's indicator status:
