This is roll up status bit set
for the following:
• Temperature Module
Unreliable Communication
• Pressure Module
Unreliable Communication
Warning
The supply voltage to the
transmitter
power terminals is too low.
Any or all of these status is
set:
Low supply voltage to: the
transmitter or,
Temp sensor module or
Press. Sensor;
or supply voltage to the
transmitter has dropped
low enough to cause a
Device Warm Reset
The supply voltage to the
transmitter terminals has
dropped low enough to
cause a warm reset of
device
Refer status bits
corresponding to unreliable
communication status of
pressure in register 121
and temperature module in
register 120 for more
details.
Internal communication
quality between
Communication board and
Temp Module or
Communication board and
Meter Body is degrading.
More than a specified
number of attempts or
actual config changes are
made, with Tamper Alarm
enabled. Warning stays
active until the specified
Tamper latency period has
elapsed. If needed, set the
Tamper attempt to
maximum value (10) or
disable the Tamper alarm
during setup stages of the
device to avoid alarm being
setup frequently. If
configuration changes are
required, contact a
qualified individual to
unlock the Write Protection
Mode feature and make
the required updates.
Check that the power
supply at terminals to be
within specification. Try to
increase the supply voltage
level. If supply voltage is
adequate and if the
problem persists, replace
the communication module
followed by Temperature
module followed by Meter
Body.
Power cycle the device. If
problem persist, Check the
terminal voltage to be
within limits. If still problem
persists, replace the
Terminal block assembly. If
problem continues replace
the Communication module
