Problem
Probable Cause
What to do
Alarm setpoints or
analog output
channels disabled
Setup parameters that
affect voltage/current/
power were changed
Define these setup
parameters (wiring
mode, PT ratio, CT
primary current) prior
to setting up alarm
setpoints/analog
channels.
Status inputs setup
not accepted
1. The analog selector
inputs and the
external
synchronization
pulse input overlap.
2. Allocated inputs for
the analog output
selector are not
contiguous and do
not start from input
#1.
Check that all inputs
are allocated correctly
Cannot store pulsing
output setup
1. You assigned a
parameter to a
relay output with
zero number of
unit-hours per
pulse
2. You selected an
output parameter
already assigned to
another relay
output.
1. Check that no. unit-
hours is within
allowed range (1-
9999)
2. Check that output
parameters are
assigned correctly.
Cannot store
setpoint setup
Setpoint action is
directed to a relay
already allocated for
pulsing
Check definition of
setpoint actions
Cannot enter
reset
menu
1. Reset function
disabled
2. You are at SEE
level (viewing only)
1. Enable reset
function in BASIC
setup
2. Go to CHG (editing)
level
No phase energy
readings displayed
Phase energy not
enabled in BASIC
setup
Enable phase energy
measurement
TXD LED flashes
continuously after
turning on instrument
Analog expander AX-7
outputs are allocated
If analog expander not
used, analog outputs
must be cancelled
