The meter saves the totalled consumed quantity every 10 minutes� After
a power failure this value is available as the current meter reading� If a
time-controlled reset is set, the elapsed time of the set reset interval is
also saved� So the possible data loss can be maximum 10 minutes�
The meter can be reset as follows:
→ 10.3.4 Manual counter reset�
→ 10.3.5 Time-controlled counter-reset�
→ 10.3.7 Configure meter reset using an external signal�
4.3.1 Consumed quantity monitoring with pulse output
Output 1 indicates a counting pulse when the set volumetric flow quantity has
been reached (→ 10.3.1)�
4.3.2 Consumed quantity monitoring with preset counter
Output 1 switches when the set volumetric flow quantity has been reached (→
10�3�2)� 2 types of monitoring are possible:
1� Time-dependent quantity monitoring (→ 10.3.5 Time-controlled counter-reset):
- If the quantity x is reached during t, output 1 switches and remains switched
until the counter is reset�
- If the quantity x is not reached after the time t has elapsed, the meter is auto-
matically reset and counting starts again; output 1 does not switch�
2� Non time-dependent quantity monitoring (→ 10.3.6 Deactivate meter reset)
- If the quantity x is reached, output 1 switches and remains switched until the
counter is reset�
4.4 Temperature monitoring
The following signals are provided for temperature monitoring:
1� A switching signal for temperature limit values on output 2 (→ 4.5)�
2� An analogue signal proportional to the temperature (4���20 mA or 0���10 V) on
output 2 (→ 4.6)�

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:
