Error Recommended action(s)
Flow temperature is
outside the alarm limits • Startup issues:
— Verify that there is voltage to the temperature sensor from
either the meter's power supply board or from an external
power supply.
— If using an analog pressure device, verify that the temperature
sensor is properly wired to the connector.
— Verify the input is properly configured for your temperature
input.
— If using a flow computer to write temperature to the meter,
verify that it is properly writing to fixed flow temperature in the
proper units.
• Run time issues:
— Adjust temperature of process fluid to within alarm limits.
— If using an analog temperature device and input reading is 0,
check if
IsAI1Avail is equal to 1 in the Meter Information dialog
in MeterLink. If it is not 1, either the I/O Board has been
removed or is damaged. Reinstall or replace the board if this
value is 0.
— If using an analog temperature device, verify that the
temperature sensor is working properly.
— If using an analog temperature device, recheck wiring and
switch settings.
— If a flow computer is writing values to the fixed flow
temperature, verify that the flow computer is still writing valid
values without Modbus write errors.
— Reverify the temperature input settings are correct.
