-The meter saves the totalled consumed quantity every 10 minutes� In the
event of a power failure this value is retained as the current meter reading� If
a time-controlled reset is set, the elapsed time of the set reset interval is also
stored� So the possible data loss can be maximum 10 minutes�
There are different ways to reset the meter → 10.4.3 Manual counter reset
→ 10.4.4 Time-controlled counter-reset
→ 10.4.6 Configure counter reset using an external signal
4.4.1 Consumed quantity monitoring with pulse output
Output 1 indicates a counting pulse when the set volumetric flow quantity has
been reached (→ 10.4.1).
4.4.2 Consumed quantity monitoring with preset counter
2 types of monitoring are possible:
Time-dependent quantity monitoring (→ 10.4.4 Time-controlled counter-reset).
-If the quantity x is reached during t, output 1 switches and remains switched
until the meter is reset�
-If the quantity x is not reached during the time t, the meter is automatically
reset and counting starts again; output 1 does not switch�
Quantity monitoring not time-dependent (→ 10.4.5 Deactivation of the counter
-If the quantity x is reached, output 1 switches and remains switched until the
meter is reset�
4.5 Temperature monitoring
The following signals are provided for temperature monitoring:
•
A switching signal for temperature limit values on output 2� On the switching
functions → 4.7.
•
An analogue signal proportional to the temperature (4���20 mA or 0���10 V) on
output 2. On the analogue functions → 4.8.
4.6 Empty pipe detection
The unit detects when the two electrodes are not wetted by the medium (→ 4.1
Measuring principle for volumetric flow monitoring)� The empty pipe detection can
be activated or deactivated (→ 10.6.9). If it is active and the pipe is empty, the unit
reacts as follows:
