(POS. 6.5-6) Function and the range of current output n.1-2
[Out mA1-2=X÷XX+]
The function associated to the signal current on output N.1-2. The current output N.1 is optional
and it is mounted on the main board. There are three fields to modify for this function:
Scale zero: 4 or 0mA;
Full scale: 20 or 22mA
Field: + = positive, - = negative, blank = both, -0+ = central zero scale
The values corresponding to the scale points are shown in the following chart:
In hardware alarm conditions “HARDW AL.” (interrupted coils, empty pipe, measure error) the current
value is programmed by the function “mA v.fault” (pos. 4.6) and it is expressed as percentage of a
fixed current range, where: 0% = 0mA and 110% = 22mA.
MENU 8 - DISPLAY
(POS. 8.3) Display contrast set
[Contrast=X]
Visual display contrast set. The contrast can change according to the room temperature. The set
values are from 0 to 15. The entered value has effect only when leaving the function itself.
WARNING >10 is a dark screen and obscures writing on the display
Contrast also can be set from visualization pages pushing the key for 8 seconds or
more. In this way the contrast set that will be visualized at release of the key.
(POS. 8.10-11) Conversion factor for flow rate totalizers
[EUR/dm³+/- =X]
Setting of the conversion/currency value for direct (and reverse) flow totalizers. There are three
setting fields for this parameter, from left to right: 1) monetary symbol, 2) default/personalized
monetary symbol, 3) conversion coefficient. To modify, set the cursor over the required field. Setting
the monetary symbol can be achieved in two ways:
1.
Choosing one of the 7 predetermined monetary symbols (standard ISO 4217-REV81):
EUR=Euro; USD=USA dollar; CAD=Canadian dollar; AUD=Australian dollar; GPB=English
pound; CHF=Swissfranc; JPY=Japanese yen.
2.
Entering a three character (numbers or letters) personalized currency. To change the
characters, the cursor must be set on the symbol “/” (second field)
