Function

Input Range

Description

1.3.0 Current output I

This configures the current output.
These functions are independent
from what is displayed.

Select Off, Level,
Distance, Volume* or
Ullage volume*

1.3.1 Current 1 item

Level

Selection of the required function for
the current output.

Select 4-20mA or 4-
20mA + 22 mA on
error.

1.3.2 Current 1 range

4-20mA

This parameter defines the status
which the current output assumes in
the event of a fault:
4-20 mA (last measured value held in
the event of a fault)
4-20 mA / E = 22 mA (is set to 22 mA
in the event of a fault).

Enter a value from 0
mm** to a value lower
than that entered for
Fct. 1.3.4 Scale I
max.

1.3.3 Scale I1 min.

As per order

This function defines the lower limit
of the analog measuring range.
It is 4 mA.
The value of this parameter always
has to be lower than the value
selected for Fct. 1.3.4: Scale I1 max.

Enter value higher
than the value
selected under Fct.
1.3.3. “Scale I min.”
up to tank height or
the maximum volume
table value***

1.3.4 Scale I1 max.

As per order

This function defines the upper limit
of the analog measuring range. It is
20 mA.
The value of this parameter must
always be:
- lower than or equal to the value
selected under Fct. 1.1.1: Tank height
or the maximum volume table value,
- higher than the value selected under
Fct. 1.3.3: Scale I1 min., otherwise an
error message will appear during
parameter check.

Select No delay, 10
sec., 20 sec., 30 sec.,
1 min., 2 min., 5 min.
or 15 min.

1.3.5 Error delay

No delay

This menu is only available when
(4-20 mA / E = 22 mA) has been
selected under Fct. 1.3.2: Current 1
range. With this parameter, a time
delay can be defined for transition of
the current output to 22 mA after an
error has been noted. During the
delay, measurement and the analog
output are held. When the error
disappears, the delay also serves to
return to the measuring mode.


* complete fct. 1.7.2 “Input table” before selecting “volume “ or “ullage volume”.
**

or other unit selected in fct. 1.2.4 Length Unit, 1.2.5 Volume Unit depending on the item

selected in fct. 1.3.1 Current 1 Item.
*** depends on the value selected in fct. 1.3.1 Current 1 Item.
