Error Description
Err 1-----
Low
Battery
Error
Battery Voltage
Low
Battery Not
Connected
Properly
A low battery check is
performed once a day and
upon a set clock procedure. If
a low battery is detected, the
condition will remain until the
battery is replaced. As long as
the meter is not powered down
with a dead or missing battery,
the meter will continue to
function as normal. When the
battery is replaced while the
meter is powered up, the
meter will automatically detect
the new battery and clear the
error condition.
If the meter is powered down
with a dead or missing battery,
then, when power is restored,
the meter's clock will be off by
the duration of the outage, and
Load Profile and TOU will be
halted. When the battery is
replaced, a set clock
procedure is needed to clear
low battery error condition.
This will also restart TOU and
clear and restart Load Profile.
To retain data for TOU and Load Profile, the battery must be replaced
with the power applied to the meter.
Err -2----
Loss of
Phase
Error
The voltage on
one of the
phases dropped
below 45 volts.
The voltage on each phase is
checked every five seconds. A
phase must fail twice in a row
to cause an error.A Demand
Reset or a Clear STD or MFG
Status Flags after the voltage
returns will clear this error.
Err --3---
Time-of-
Use (TOU)
Error
•
Current Season
is not
programmed.
•
Current Year is
not
programmed.
•
TOU halted due
to power down
with dead or
missing battery.
This is tested at power-up, at
midnight crossings, at season
changes, upon reconfigures
and upon set clocks.
Depending on the cause of the
error, it can be cleared with a
corrective reconfigure or with a
set clock with a good battery
present.
