Flow pressure is outside the alarm
limits
•
Startup Issues:
—
Verify that there is voltage to the pressure sensor from either the meter's
power supply board or from an external power supply.
—
If using an analog pressure device, verify that the pressure sensor is properly
wired to the connector.
—
Verify the input is properly configured for your pressure input.
—
If using a flow computer to write pressure to the meter, verify that it is
properly writing to fixed flow pressure in the proper units.
•
Run Time Issues:
—
Adjust pressure of process fluid to within alarm limits.
—
If using an analog pressure device and input reading is 0, check if IsAI1Avail is
equal to 1 in the Meter Information dialog in Daniel 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 pressure device, verify that the pressure sensor is working
properly.
—
If using an analog pressure device, recheck wiring and switch settings.
—
If a flow computer is writing values to the fixed flow pressure, verify that the
flow computer is still writing valid values without Modbus write errors.
—
Reverify the pressure input settings are correct.
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 temperature 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
IsAI2Avail is equal to 1 in the Meter Information dialog in Daniel 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.
