10.2 LCD Menu Features
To enter the menu briefly press or button. A menu
tree can be found in Appendix A – Lcd Menu Tree Overview.
Menu features are fully described in Appendix B – Lcd Menu
Tree Descriptions.
10.3 LEDs and Status Codes
LEDs give two types of status codes. The first type is a single
color NAMUR status. The second type is a 4-blink status that
correlates to a specific positioner error or condition.
Regardless of the type of code (1 blink or 4), the LEDs always
indicate a code corresponding to the highest priority alarm,
warning, alert or status that is currently active.
10.3.1 Single Blink NAMUR Color Codes
If buttons on the positioner have not been pressed recently,
the positioner will blink one color. This color represents one of
the 5 conditions outlined in the NAMUR standard, NE-107.
These are listed in Table 3: NE 107 Status Code. How these
colors are assigned to specific conditions can be customized
in the DTM.
Table 3: NE 107 Status Code
10.3.2 4-Blink Status Codes
When a button is pressed on the positioner, the color code will
expand to a 4-color sequence. This corresponds to one of the
specific status indications listed in Appendix D – 4-Blink Status
Codes. When multiple codes are active, only the highest
priority condition is represented by the blink code. To see all
of the active alarms and status conditions, use a DD or DTM.
10.4 Tamper Lock
In order to prevent unintentional adjustments of the
configuration, tuning, or control of the valve, the Tamper Lock
feature may be used. This is set in the DTM and disables the
buttons and menus except for the ability to view the status of
the positioner. When locked, the positioner may be
temporarily unlocked by entering a PIN. The PIN may be
entered using LCD. The tamper lock feature can also be
disabled in the DTM.
10.5 Write Protect (HART)
Similar to the tamper lock feature, write protect prevents
unauthorized changes from across the network. Write protect
restricts configuration changes and activation of diagnostics
and calibrations. Write protect can be enabled and disabled
by holding the hot key sequence and for 9 seconds.
The blue LED will light, indicating write protect has been
enabled or disabled. The LED lights will flash status code Y-
G-B-B when write protect is enabled and status code R-O-Y-
B when it is disabled.
NOTE: The write protect function is supported by
firmware code version 1.07 and later.
10.6 Batch Schedule Task (BST)
The Batch Schedule Task (BST) function is a Pro positioner
model function designed to allow a user to schedule the
performance of a sequence of diagnostic tasks. The BST is
valuable for tracking changes in system operation over time,
which can be useful in identifying a developing or existing
problem. The BST is managed through the DTM and allows
the following diagnostic tasks to be scheduled in a batch task
sequence:
