Troubleshooting

The information in Table 14–1 on page 106 describes potential problems and their possible causes. It also describes checks you can perform or possible solutions for each. After referring to this table, if you cannot resolve the problem, contact your local Schneider Electric sales representative for assistance.

HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH

•Apply appropriate personal protective equipment (PPE) and follow safe electrical practices. For example, in the United States, see NFPA 70E.

•This equipment must be installed and serviced only by qualified personnel.

•Turn off all power supplying this equipment before working on or inside.

•Always use a properly rated voltage sensing device to confirm that all power is off.

•Carefully inspect the work area for tools and objects that may have been left inside the equipment.

•Use caution while removing or installing panels so that they do not extend into the energized bus; avoid handling the panels, which could cause personal injury.

Failure to follow these instructions will result in death or serious injury.

Heartbeat/Comms LED

The heartbeat/comms LED helps to troubleshoot the power meter. The heartbeat/comms

LED works as follows:

•Normal operation — the LED flashes at a steady rate during normal operation.

•Communications — the LED flash rate changes as the communications port transmits and receives data. If the LED flash rate does not change when data is sent from the host computer, the power meter is not receiving requests from the host computer.

•Hardware — if the heartbeat LED remains lit and does not flash ON and OFF, there is a hardware problem. Perform a hard reset of the power meter (turn OFF power to the power meter, then restore power to the power meter). If the heartbeat LED remains lit, contact your local sales representative.

•Control power and display — if the heartbeat LED flashes, but the display is blank, the display may not be functioning properly or may have timed out (see “Setting Up the Display” on page 8). If the display is blank and the LED is not lit, verify that control power is connected to the power meter.
