Error Recommended action(s)
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.
CPU Module LINK LED
• When connecting directly:
— Check the cross-over cable connection
(P/N 2-3-3400-079)
• 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 Daniel 3410
Ultrasonic Flow 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
