• In addition the value before the last reset is stored� This value can also be
displayed�
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 stored�
So the possible data loss can be maximum 10 minutes�
• Overflow: After the maximum value (9,999,999 Nm³) the meter is reset to 0�
The meter can be reset as follows:
• Manualreset(→9.3.3.).
• Time-controlledautomaticreset(→9.3.3).
• Externalinputsignalonpin2(→9.3.5).
4.3.1 Consumed quantity monitoring with pulse output
Output 1 provides a counting pulse each time the value set in [ImPS] is reached
(→9.3.1).
4.3.2 Consumed quantity monitoring with preset counter
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 via the digital input or [rTo] = [rED�T]�
In this case the time-controlled totalizer reset is not carried out if [ImPS] =
quantity X exceeded�
- 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�
- Settings: [ImPS] = quantity x, [ImPR] = [no], [rTo] = [OFF]�
- 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.
