2.2 Troubleshooting the meter
Table 2-2 and the following sections show errors that may occur with the meter hardware,
firmware or connections and recommend actions to resolve the problem(s).
Table 2-2: Troubleshooting
Error Recommended action(s)
Acquisition Module Error • Check/Replace I.S. Barrier.
• Check/Replace Acquisition 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
compatible with
firmware
• Check Acquisition Module is compatible with Model # configured in
meter (i.e. 3414 4-path or 3418 8-path).
• Replace the Acquisition Module.
Chord failure • Chord is hard failed (Model 3414 - Chord A, Chord B, Chord C or
Chord D; Model 3412 - Chord A or Chord B; or 3411 Chord A) 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 connections are secure
and wired correctly.
— 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 holder. 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.
