pres_sensor
_comm
_timeout
If there is no
communication between
Communication Board and
Pressure Sensor Board
(Meter-body) or invalid
data on communication
line due to noise
User can verify the
cable/connector between
communication and
Pressure sensor board
(Meter body) to ensure that
it is not damaged. Check
for bent pins.If
cable/connector is not the
problem, replace the
Communication module.If
problem still persists,
replace the meter body.
Bit - 6
temp_sensor
_comm
_timeout
If there is no
communication between
Communication Board and
Temperature Sensor
Board (Terminal) or invalid
data on communication
line due to noise
User can verify the
cable/connector between
communication and
Temperature sensor board
(Terminal Board) to ensure
that it is not damaged.
Check for bent pins.If
cable/connector is not the
problem, replace the
Communication module.If
problem still persists,
replace the Terminal
board.

comm_vcc
_fault
Power Supply failure
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
Bit - 8
