Troubleshooting the meter
and the following sections show errors that may occur with the meter hardware,
firmware or connections and recommended actions to resolve the problem(s).

Error
Recommended action(s)
Acquisition Module Error
•
Check interconnect cable between Acquisition Module and the CPU Module.
•
Attempt the
Program Download
procedure to install the firmware.
—
Cycle power to the meter.
—
Replace the Acquisition Module.
—
If the Acquisition Module cannot be reprogrammed, collect a complete
Archive log and contact your local area Daniel service representative.
Acquisition Module is not compati-
ble with firmware
•
Upgrade the firmware in the meter to the latest version using Daniel MeterLink
(
Tools|Program Download
). Contact your Daniel service representative to obtain
the latest firmware or download the firmware from:
http://www2.emersonprocess.com/en-US/brands/daniel/Pages/Daniel.aspx
•
Replace the Acquisition Module.
Chord failure
•
Chord is hard failed (Chord A, Chord B, Chord C or Chord D) and meter is unable to
obtain measurement data from this pair of transducers.
—
If Chord A is failed and no other transducers are failed or are reporting status
alerts, the issue is most likely isolated to this pair of transducers or its cabling.
Check the transducer wiring for this pair of transducers to make sure connec-
tions are secure and wired correctly.
—
Verify that the meter run is not partially full where the top transducer pair are
not submerged in the process fluid.
—
Verify the average gain of this transducer pair is not above 90dB. The gain
value can be read in Daniel MeterLink on the Monitor page.
—
Remove the transducer cable from the transducer and measure the resistance
with an Ohm meter across the two pins on the back of the transducer
housing. If the value is over 2 ohms, replace the transducers.
—
If transducer cabling allows, swap cabling of failed transducer pair with a pair
with equal path lengths. If the alarm remains active for this chord, then the
transducers are working properly. If this alarm clears but the chord that was
swapped now fails, the issue is with the transducer.
—
Collect a Maintenance Log, Configuration file and Waveform stream file with
Daniel MeterLink and contact your Daniel service representative.
CPU Module LINK LED
•
When connecting directly:
—
Check the cross-over cable connection (P/N 1-360-01-596)
•
When Using a Hub:
—
Use straight-through patch cable between the meter and the hub and a
straight-through patch cable between the hub and the PC
—
Do not connect either the meter or PC to the hub UPLINK port.
—
Check the CPU Module LED 1 is on (either solid red or flashing green). If the
LED is not on, check power to the meter.
—
If the LED is on, check the Ethernet cable connections
