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 → 4.6.
•
An analogue signal proportional to the temperature (4���20 mA or 0���10 V) can
be provided on output 2. For the analogue functions → 4.7.
4.5 Empty pipe detection
The unit signals that there is no medium in the pipe�
The empty pipe detection can be activated / deactivated (→ 9.5.3). If it is active
and the pipe is empty, the unit reacts as follows:
•
[SEnS] is indicated in the display�
•
The quantity meter for monitoring consumed quantities is stopped and no
counting pulses are provided on OUT1�
•
If OUT2 is configured as analogue output for flow monitoring, the output signal
goes down to the value 4 mA or 0 V�
