If Not Configured
No Configuration Allowed – Because the card type has not been
selected, no configuration options are available.
If Set As AO Card
Set 0% - Set the current (mA) that will correspond to the 0% (closed)
valve position.
Set 100% - Set the current (mA) that will correspond to the 100%
(open) valve position.
NOTE:
The AO calibration values are required to match the
“Signal At Closed” configuration switch on the positioner. For
example, if the switch is set to 4 mA, the “Set 0%” current must
be less than the “Set 100%” current.
If Set As DO Card
Use DTM – The DO is highly configurable. Use the ValveSight DTM
to set the function of the DO. When used with the 510+, DO is not
configurable and triggers only off the Position Deviation alarm.
If Set As DI Card
Set to No Action – Use this option if only an acknowledgement of the
DI state is desired.
Set to Trigger PST – Use this option to initiate a partial stroke test
when the DI state goes high.
Set to Command Override - Use this option to override the analog or
digital command input to move the valve to a set position as long as
the DI state remains high.
Set Command Point – Use this feature to set the override position.
The position is a final command (not characterized). Tight Shutoff
settings and Soft Limits will still apply.

11 HART COMMUNICATION
The Logix 520MD+ series positioners use the HART communication
protocol specified by the HART Communication Foundation.
11.1 ValveSight DTM
Flowserve Corporation has produced a custom Device Type Manager
(DTM) for the Logix 520MD+ digital positioners to support the Valve-
Sight diagnostics platform.
The DTM contains a high level “Dashboard” view of the system health
and status information. See Figure 40. It also contains comprehensive
user-friendly interfaces for control and reporting of alarms, of-line and
on-line diagnostic tests, calibrations and system configurations.
The ValveSight DTM is available from a Flowserve representative or
from www.valvesight.com.

11.2 HART 375/475 Handheld Communicator
The Logix 520MD+ digital positioner supports and is supported by the
HART 375/475 Handheld Communicator. The Device Description (DD)
files can be obtained from the HART Communication Foundation or
from your Flowserve representative.
11.3 Changing HART Versions
The Logix 520MD+ positioner comes standard with the HART 6 com-
munication protocol. Follow this procedure to change to HART 5 or 7.
1. Remove the outer cover.
2. Remove the inner cover by removing the 6 inner cover retaining
screws.
