4.7 Installation Diagnostics
Following is a list of diagnostic messages that may appear on the meter display.
DIAGNOSTIC MESSAGES SHOULD NOT BE ON CONTINUOUSLY WHEN THE
METER IS INSTALLED PROPERLY AND IS IN WORKING ORDER.
4.7.1 Line Voltage Diagnostics
The diagnostics program detects line voltage faults by displaying one of two
messages:
Error Messages:
PH Seq Err
PH Loss C
PH Seq Err indicates that the 3-phase line voltage is not hooked up in the proper
phase sequence. This message should never be seen continuously on the display
during normal operation. The meter will not display correct electrical data in this
condition. The phase sequence error must be remedied in order for the meter to work
properly.
PH Loss C indicates that the line voltage is missing on Phase C. This message will
appear whenever the power on Phase C is off.
4.7.2 Current Sensor Diagnostics
The load current must be at least 1% of the meter's rated load in order to use the
diagnostic function.
Current sensor diagnostics can detect:
1. Reversed current sensors
2. Incorrect phase correspondence
Error Messages:
CT Err A
CT Err A B
CT Err A C
CT Err: (ABC) is used to detect the swapping or mis-wiring of current sensor
phases.
