Emerson Daniel 3410 Series Instructions For Use, Maintenance And Installation

2.1.3 Chord A, Chord B, Chord C and Chord D alarm
Chord A, Chord B, Chord C, and Chord D - These alarms indicate how a chord is
functioning.
LED Color Problem
Green No alarms are present. Chord is operating properly.
Yellow At least one sample in the batch caused an alarm but it did not cause
the chord to fail. The sample will not be used in the batch. Discarding
occasional samples can occur during normal operation such as during
flow velocity changes.
Red The chord has failed or is in acquisition. This chord is not used for this
batch. Chords that have failed or are shown to be in acquisition for
repeated batches indicates that the meter should be inspected by a
service technician.
Gray The chord has manually been set to inactive.
2.1.4 Field I/O alarm
Reports various field I/O devices that are in alarm. Click the Check Status button for more
details on specific alarms. The field is grayed out if the Daniel 3410 Series Ultrasonic Gas
Flow Meter does not support this alarm.
2.1.5
Validity alarm
This alarm indicates that the meter may not be measuring accurately. Click Check Status
to see a description of which validity alarms are active. The validity alarms QMeter and
QFlow indicate an issue with the meter collecting enough information from the chords to
make an accurate measurement. The validity alarms for pressure and temperature
indicate that the value is above or below the alarm limits for these values. Red and green
are the only colors used for this alarm.
2.1.6
Comms alarm
The Comms alarm indicates that communications between Daniel MeterLink and the
meter failed. This could be due to a poor communication link. Daniel MeterLink continues
to retry communications. Red and green are the only colors used for this alarm.
2.1.7
Communications
The Communications Analyzer (via Daniel MeterLink
™
Tools → Menu → Communications
Analyzer menu path) displays communications between Daniel MeterLink and the
ultrasonic meter. This utility is useful for troubleshooting communications to the meter. It
displays many of the TCP/IP commands between Daniel MeterLink and the connected
meter.

®
Protocol, refer to Section 5 of the Emerson 475 Field Communicator User’s Manual, Rev D.
