ALERT POTENTIAL ISSUE POSSIBLE SOLUTION
“Error EEPROM fail” H/W failure of meter non-volative storage Contact ONICON. RMA needed
“Error SPI/I2C fail” Meter internal communication bus failure Check power supply to the meter is ##
“Error Velocity Cong Corrupt” Velocity Tables / Pipe Info not present, corrupt,
or unable to nd velocity table for congured
pipe
• Congure the meter for a common pipe (e.i. 6””
Carbon Steel Sch40).
• If the error disappears, power cycle the unit
to conrm if the error no longer exists.
• If the error reappears, contact ONICON. RMA
needed. The Meter could lost the memory.
• If the error is no longer present after changing it
to a common pipe, change the pipe conguration
to the desired pipe conguration. Conrm the
desired pipe conguration exists. Contact ONICON
if help is needed to select the correct pipe
conguration.
• Update rmware on the unit and load a new pipe
conguation le using the onicon software.
“Error Pipe Not Congured” Pipe conguration missing or incomplete Congure pipe through Pipe Cong Settings screen.
“Error Grand Totals Corrupt” Valid totals could not be retrieved from meter
non-volative storage
• Restore Factory Conguration thorugh Utility
Menu-> Factory Restore.
• Run ow or simulate ow to increase totals.
• Power cycle the unit. If the error reappears, contact
ONICON support. RMA needed (Meter might lost
its memory)
“Error Yearly Totals Corrupt” Valid totals could not be retrieved from meter
non-volative storage
• Restore Factory Conguration thorugh Utility
Menu-> Factory Restore.
• Run ow or simulate ow to increase totals.
• Power cycle the unit. If the error reappears, contact
ONICON support. RMA needed (Meter might lost
its memory)
“Error Elec 1 Bad DC Oset” Persistent invalid reading - electrode 1 • Power o the unit, and check all wires are
connected per the wiring label on the lid
• Remove the terminal block on TB8 ELEC1.
• Check continuity on cable red and black. (conrm
the meter sensor is on water)
• If there is no continuity. Go to the sensor and
open its enclosure, remove terminal P1 ELEC1,
and measure continuity on pins A and B.
• If there is no continuity, carefully remove the
terminal board of the sensor and check if
all cables are connected on the back of the
board.
• If the cables are connected, contact ONICON.
RMA need (possible bad stem)
• If any cable is corrected during the continuity
test, power on the unit and check the error, it
should disappear.
