4.3.1 Consumed quantity monitoring with pulse output
Output1providesacountingpulseifthevaluesetin[ImPS]isreached(→9.3.1).
4.3.2 Consumed quantity monitoring with preset meter
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�
4.4 Monitoring of temperatures
• 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.
4.5 Volumetric flow or temperature monitoring / switching
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�
