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 or a Clear
STD or MFG Status Flags with
power being delivered 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 or a Clear
STD or MFG Status Flags 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.
