7.4 MA ANALOGUE OUTPUT [3.0]
Item 3 of the main menu allows for definition of the parameters in current (see Fig. 7-7).
Figure 7-7 Menu “ANALOGUE OUTS”
The programme has two parameters:
“OUT 1”
“OUT 2”
They can be selected according to the contents of paragraph 7.1 b).
7.4.1 OUT 1
It defines the outward parameters mA 1.
The “MEASURE” field selects the size to be used:  “FLOW” or
 “TEMPERAT.”
The field “TYPE” defines the output type:  0-20 mA or
 4-20 mA.
The field “INF LIM” defines the value of the size at 0 or
4 mA if it has been chosen, respectively:
 “TYPE”=0-20 mA or
 “TYPE”=4-20 mA.
The field “SUP LIM” defines the value of the size to:
 20 mA
The field “NAMUR” is only important if:
and it undertakes the values “NO” or “YES”; in the second
case the current output is forced to:
 “TYPE”=4-20 mA
 2.40 mA in the
presence of an alarm
Every time the field “FLOW” (par. 7.2.4.2.) is modified, all
of the default values are reset for:
 “INF LIM”
 “SUP LIM”
7.4.2 OUT 2
It defines the output parameters mA 2.
The field “MEASURE” selects the size to be used:
 “FLOW”
 “TEMPERAT” or
 “LEVEL” (recess).
The field “TYPE” defines the type of output:  0-20 mA or
 4-20 mA.
