Should the flowmeter encounter an error condition, an
error message is shown on the display. Current output
is always forced to 22.4 mA during an error condition
as shown below:
This message is shown with its error code number and
alternates with the normal flow data. The error text
message is displayed only for the error with the highest
priority while all the active errors are indicated by their
error code numbers.

> 1 1 5 %
WARNING
ALL FLOWMETERS AND/OR SIGNAL CONVERT-
ERS BEING RETURNED TO ABB INC. FOR
REPAIR MUST BE FREE OF ANY HAZARDOUS
MATERIALS (ACIDS, ALKALIS, SOLVENTS,
ETC.). A MATERIAL SAFETY DATA SHEET
(MSDS) FOR ALL PROCESS LIQUIDS MUST
ACCOMPANY RETURNED EQUIPMENT
