-If the quantity x is reached during the time t, output 1 switches and remains
switched until the meter is reset via the digital input or [rTo] = [rED�T]�
4.4 Temperature monitoring
• A switching signal for temperature limit values can be provided on output 2�
Switching functions → 4.5.
• An analogue signal which is proportional to the temperature (4���20 mA) can be
provided on output 2. Analogue functions → 4.6.
4.5 Volumetric flow or temperature monitoring / switching
function
OUTx changes its switching status if it is above or below the set switching limits
(SPx, rPx)� The following switching functions can be selected:
4.5.1 Hysteresis function
Normally open: [OUx] = [Hno]
Normally closed: [OUx] = [Hnc]
First the set point (SPx) is set, then the
reset point (rPx) with the requested
difference�
When SPx is adjusted, rPx is
changed automatically; the differ-
ence remains constant�
Example of volumetric flow monitoring
HY = hysteresis
