• Max. Device Limits: Messages are generated when the process variable is outside the measuring
range. The “failure” or “out of specification” icons are shown; the corresponding relay contact is
enabled. The current outputs can signal a 22-mA message (user-defined).
• Variable Limits: Upper and lower limits at which a message is generated can be defined for the
“failure” and “out of specification” messages.
Displaying Messages
Go to the Diagnostics menu if the “failure”, “maintenance required”, or “out of specification” icons are
flashing on the display.
Menu Selection
Diagnostics
Message List
All active messages are displayed in the “Message List” menu item with the following information:
Error number, type (failure, maintenance required, out of specification), channel, message text.
You can scroll forward and backward using the
up/down arrow keys
.
The error message disappears from the display around 2 s after the error is cleared.
An overview of message texts with notes on troubleshooting can be found in the “Troubleshooting”
chapter.
7.2.3 Logbook
The logbook shows the last 100 events with message number, date, and time directly on the device,
e.g., calibrations, NAMUR messages, power failure. Messages that occur during the function check
(HOLD) operating state are not saved.
