•
In addition the value before the last reset is saved� 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 saved�
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
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 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�
•
Non time-dependent quantity monitoring�
-Settings: [ImPS] = quantity x, [ImPR] = [no], [rTo] = [OFF]�
-If the quantity x is reached, output 1 switches and remains switched until the
counter is reset�
4.4 Temperature monitoring
•
A switching signal for temperature limit values can be provided on output 2� On
the switching functions → 4.5.
•
An analogue signal which is proportional to the temperature (4���20 mA) can be
provided on output 2. On the analogue functions → 4.6.
