31.2 Installation check using the meter display
After the meter has been properly connected, its function can be tested as follows:
Scroll mode As long as the alternate button is not pressed, the scroll mode will
appear. Depending on the version involved, this may consist of one
value or of several values, shown in a rolling display mode.
Display check When the alternate button 1 is pressed, the first thing to appear is the
display check.
All segments of the display must be present. Pressing the alternate
button will switch the display to its next value.
Error message If the display check is followed by an error message
Fast run-through If the alternate button is repeatedly pressed at intervals of 2s < t <5s ,
all the main values provided will appear.
Phase failure Display elements L1, L2, L3 are used to indicate which phases of the
meter are energized.
Rotating-field detection If the meter's rotating field has been inversely connected, the phase
failure detection symbols will flash.
creep check If the meter starts measuring, the energy pulse diode will blink
according the measured energy. The relevant arrows (+P, -P, +Q, -Q)
on the display are switched ON after 2-3s.
Anti-creep check If the meter is in idling mode, the energy pulse diode will be
continuously lit up. The relevant arrows (+P, -P, +Q, -Q) on the
display are also switched off.
Reverse run If the meter is measuring in 1 or 2 phases in the reverse direction, the
appropriate arrow under the L1, L2, L3 symbol is displayed.
Attention!
Phase and neutral mix up
If during the installation process of a 3x230/400V meter phase and
neutral will be changed the meter will responds on the LCD as follow:
• blinking of L1, L2, L3 segments
• activation of the error indicator
• log file event will be created
In that case the power of the meter should be switched off
immediately and the installation should be checked again. Otherwise
the meter can be damaged after 12h.
