cursor.
•
[ ] to decrease the value (or move the
decimal point one digit to the left) or
[

move the decimal point one digit to
the right).

100% range. Use this step to give the 100%
output setting in the tank. Refer to the
illustrations that follow. Illustration
1
shows the settings for level. Illustration
2
shows the settings for distance.
Refer to the illustrations that follow. When
menu item A4.1.3.1 Current Out. 1 Var. is set to
"Level", illustration
1
shows the position of
100% output as a level above the tank bottom.
When menu item A4.1.3.1 Current Out. 1 Var.
is set to "Distance", illustration
2
shows the
position of 100% output as a distance below
the flange facing or thread stop of the process
connection.

current output range (3.8-20.5 mA
(NAMUR), 4-20 mA, 3.8-20.5 mA

Current output range. This menu item gives
current output values to the measuring range
between 0% and 100% values given in the "0%
range" and "100% range" steps.
If you set this menu item to "4-20 mA" or "3.8-
20.5 mA":
•
0% Range = 4 mA
•
100% Range = 20 mA
If you set this menu item to "4-20 mA
(reversed)" or "3.8-20.5 mA (reversed)":
•
0% Range = 20 mA
•
100% Range = 4 mA
•

error function (Off, Hold, High or
Low).

Error Function. This sets the behaviour of
current output 1 if an error occurs.
If this menu item is set to "Off", no signal is
given (this parameter is not available if menu
item C4.1.4 is set to "3.8-20.5 mA" (NAMUR) or
"3.8-20.5 mA (reversed)"). If this menu item is
set to "Hold", the output current stays at the
value where the error occurred (this parameter
is not available if menu item C4.1.4 is set to
"3.8-20.5 mA" (NAMUR) or "3.8-20.5 mA
(reversed)"). If this menu item is set to "Low",
the output current changes to 3.5 mA (default
value) if an error occurs. If this menu item is set
to "High", the output current changes to
21.5 mA (default value) if an error occurs.
