E-MON CLASS 3400 METER

6.6 Line Voltage/Current Sensor 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.
6.6.1 Line Voltage Diagnostics
The diagnostics program detects line voltage faults by displaying one of two
messages:
PH Missing: B C or Phase sequence error.
PH Missing: B C: Indicates that the line voltage is missing on Phase B and/or
Phase C. This message will appear whenever the power on either Phase B or
Phase C is off. Screen 5 (Voltage per Phase) will also indicate a loss of line voltage.
Phase sequence error: Indicates that the 1-phase or 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 problem must be
remedied in order for the meter to work properly.
