E50C1A Installation Guide

Problem

Cause

Solution

The maintenance wrench icon 

appears in the power meter display.

There is a problem with the 

inputs to the power meter.

See the Alert sub-menu or the Diagnostic Alert Modbus Register 

146

The display is blank after applying 

control power to the meter.

The meter is not receiving 

adequate power.

Verify that the meter control power are receiving the required 

voltage. 

Verify that the heart icon is blinking.
Check the fuse.

The data displayed is inaccurate.

Incorrect setup values

Verify the values entered for power meter setup parameters (CT 

and PT ratings, system type, etc.). See the Setup section.

Incorrect voltage inputs

Check power meter voltage input terminals to verify adequate 

voltage.

Power meter is wired 

improperly.

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.

Cannot communicate with power 

meter from a remote personal 

computer.

Power meter address is incorrect. Verify that the meter is correctly addressed (see Setup section).
Power meter baud rate is 

incorrect.

Verify that the baud rate of the meter matches that of all other 

devices on its communications link (see Setup section).

Communications lines are 

improperly connected.

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.
