When a HART device requires maintenance, the
engineer or the operator changes the PV Source
value of the corresponding AI channel to MAN. As
soon as the PV Source value is changed for the
channels connected to the ST 800 transmitters,
Experion communicates the channel mode status
to the corresponding ST 800 transmitters. Upon
receiving this status, if the value is MAN, the
transmitter displays an M and Available for
Maintenance on the local display of the
transmitter. The status display on the transmitter
ensures that the field technician can locate and
perform the maintenance work on the correct
transmitter without impacting the integrated
devices in the process loop. The transmitter
continues to display the Available for
Maintenance status on its local display until the
PV Source status of the corresponding AI channel
is changed to AUTO / SUB or the transmitter is
power cycled.
