Troubleshooting (continued)Table 2-1:
Error Recommended action(s)
Flow temperature is outside the alarm limits • Startup Issues:
- Verify that there is voltage to the tem-
perature 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 tem-
perature to the meter, verify that it is
properly writing to fixed flow tempera-
ture 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 di-
alog in Daniel MeterLink. If it is not 1, ei-
ther 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.
