Non-Fatal Errors
Error Code Error Possible Cause(s) Error Description
Err ---4-- Reverse
Power Flow
Error The configured
reverse power
threshold has
been reached. Reverse power is tested every
second and an accumulator for
it is maintained. If power is
delivered during the second,
then the accumulator is cleared.
If power is received during the
second, then the accumulator is
incremented. If the accumulator
reaches the configured reverse
power threshold, then the error
is triggered.
A Demand Reset will clear this
error.
Err ----5- Clock/Load
Profile Error Load Profile
halted due to
power down with
dead or missing
battery. This is tested upon power-up.
A set clock with a good battery
present will clear this error. Be
sure to read the Load Profile
data prior to setting the clock to
clear the error. The dead
battery will cause some invalid
intervals at the end of the data.
When the error is cleared, Load
Profile will be restarted from the
beginning to purge the bad
data.
Err -----6 Full Scale
Overflow
Error The calculated
W delivered
demand at an
EOI exceeded
the configured
full scale value. This is tested at a demand EOI.
The maximum demand register
continues to accumulate and W
delivered is still correctly
displayed. When a demand
reset is performed, the correct
maximum W delivered will be
added to the cumulative
register.
A Demand Reset will clear this
error.
If a full scale overflow occurs,
check the installation to ensure
that the current capacity of the
meter has not been exceeded.
A full scale overflow error in no
way affects the existing billing
data.
