STATUS AND FAULT INDICATION
Status and fault conditions are indicated using the 4–20
mA analog signal output. Signaling modes include two
predefined modes, and a user defined mode for third
party compatibility. The user defined mode allows users
to define a mA output level (range 1.0 - 3.6 mA) for
each of the three status / fault categories: configuration,
advisory, and detection disabled. Refer to Table 4 for
status indications and Table 5 for fault conditions.
Status and fault indication configuration options can
be changed via HART or Modbus communication.
(Refer to the “Troubleshooting” section for additional
information regarding fault identification.)
NOTE
Transmitter warm-up and fault conditions are
indicated by a solid yellow LED, and diagnostics
can be performed using HART or Modbus
communication. The receiver will continue to
perform its safety function, and will indicate
a fault status if normal operation has been
compromised.
If a transmitter fault occurs, perform normal
maintenance and ensure correct input voltage
at the device. If normal operation cannot be
restored, return the device to the factory.
