ST 700 Series HART/DE Option User’s Manual
Revision 4.0
Experion communicates the channel mode status to
the corresponding ST 700 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.
