Cause
There is a problem with the
inputs to the power meter.
The meter is not receiving
adequate power.
Incorrect setup values.
Incorrect voltage inputs.
Power meter is wired improperly.
Power meter address is incorrect.
Power meter baud rate is incorrect.
Communications lines are
improperly connected.
Solution
• See the Alert sub-menu or the Diagnostic Alert BACnet Binary_Input
objects.
• Verify that the meter control power are receiving the required voltage.
• Verify that the heart icon is blinking.
• Check the fuse.
• Verify the values entered for power meter setup parameters (CT and
PT ratings, system type, etc.). See the Setup section.
• Check power meter voltage input terminals to verify adequate voltage.
• Check all CTs and PTs to verify correct connection to the same service,
PT polarity, and adequate powering. See the Wiring Diagrams section
for more information.
• Verify that the meter is correctly addressed (see Setup section).
• Verify that the baud rate of the meter matches that of all other devices
• on its communications link (see Setup section).
• Verify the power meter communications connections (see the
Communications section).
• Verify the terminating resistors are properly installed on both ends of
a chain of units. Units in the middle of a chain should not have a
terminator.
• Verify the shield ground is connected between all units.
