Consumed quantity monitoring with pulse output
4.3.1
Output 1 provides a counting pulse if the value set in [ImPS] is reached (→ 9.3.1).
Consumed quantity monitoring with preset meter
4.3.2
2 types of monitoring are possible:
Time-dependent quantity monitoring
•
Settings: [ImPS] = quantity x, [ImPR] = [no], [rTO] = time t�
-
If the quantity x is reached during the time t, output 1 switches and remains
-
switched until the meter is reset�
If the quantity x has not been reached after the time t, the meter is automati-
-
cally reset and counting starts again; output 1 does not switch�
Quantity monitoring not time-dependent
•
Settings: [ImPS] = quantity x, [ImPR] = [no], [rTO] = [OFF]�
-
If the quantity x is reached, output 1 switches and remains switched until the
-
meter is reset�
Monitoring of temperatures
4.4
A switching signal for temperature limit values can be provided on output 2� For
•
the switching functions → 4.5.
An analogue signal proportional to the temperature (4���20 mA or 0���10 V) can
•
be provided on output 2. For the analogue functions → 4.6.
Volumetric flow or temperature monitoring / switching
4.5
function
OUTx changes its switching state if it is above or below the set switching limits
(SPx, rPx)� The following switching functions can be selected:
Hysteresis function / normally open: [OUx] = [Hno]�
•
Hysteresis function / normally closed: [OUx] = [Hnc]�
•
First the set point (SPx) is set, then the reset point (rPx) at the requested
distance�
Window function / normally open: [OUx] = [Fno]�
•
Window function / normally closed: [OUx] = [Fnc]�
•
The width of the window can be set by means of the distance between SPx and
rPx� SPx = maximum value, rPx = minimum value�
