Status Check
The following is a procedure for checking the status of a device based
on the results of the continual self diagnostics. The diagnostics
include monitoring the transducer, transducer temperature, transmit-
ter ambient temperature, input circuits, processor EEPROM, nonvola-
tile memory, and reference voltages.
NOTE:
When status key is pressed, the problem holding the highest
priority (based on an internal priority structure) is displayed for ABB
digital FSK devices. Any other problem that may exist cannot be
viewed until the problem with the highest priority is corrected. HART
devices show the top eight (priority) messages in a single scrollable
screen. If an error message is displayed, refer to
for trou-
bleshooting information.
Rerange Key Function
Use the rerange key to change the:
•
Upper and lower range values of the field device.
•
Upper and lower temperature alarm values of the field device
(where available).
•
Upper and lower secondary units.
•
Damping time.
NOTE:
Field device output is based on the values entered in this
procedure. The terminal will not reject invalid ranges; therefore, it is
imperative that the range limits specified for the device are known.
Refer to the applicable product instruction for range limits.
The temperature of the transducer or reference tem-
perature is displayed.
