Submenu: Totalization (option) Settings only required if this analog measuring point is to be totalized for calculating the
volume for example. For analysis periods, see "Signal analysis".
Totalization: using the totalization function, the volume in m3 can be calculated from
an analog signal (e.g. flow in m
3
/h). Picklist: no , yes
Totalization Base: select the corresponding time base. Example: ml/s -> time base
seconds (s) ; m
3
/h -> time base hours (h).
Total. Eng. Unit: here, enter the unit for the volume determined by totalization (e.g.
"m
3
").
Scroll Display: select the counter which should be displayed alternately with the
instantaneous value. Factory setting: No, Only Instant Value
Low flow cut off: specify how the device should perform low flow cut off:
Area Around Zero Point: all values in the zero point range that are smaller than the
(absolute) "Low flow cut off" are not totalized (e.g. Low flow cut off = 0.1m/h: all values
<= -0.1m/h and >= 0.1m/h are totalized; all other values are discarded).
Absolute Value: all values that are smaller than the configured "Low flow cut off" are not
totalized (e.g. Low flow cut off = 0.1m/h: all values < 0.1 m/h are not totalized).
Low flow cut off: specify the threshold value for the low flow cut off here. Factory
setting: 0 %
Calc. Factor: factor for calculating the totalized value (e.g. the transmitter returns l/s
-> totalization base = second -> desired unit is m

-> enter 0.001 as the factor). Factory
setting: 1
Submenu: Fault Mode Settings that lay down how this channel is to react under fault conditions (e.g. cable
open circuit, over range).
Fault Switches: switches the selected relay under fault conditions. The terminal
numbers are shown in brackets. Picklist: Not Used , Relay x (Term. xx-xx)
Save Event: stores an event in the event memory when a fault condition occurs.
Picklist: No , Yes
Cable Open Circ.: The cable open circuit detection function can be switched on and
off here.
In the case of thermocouples: When thermocouples are switched in parallel, enabled
cable open circuit detection causes false alarms. Picklist:
no , yes
In the 1 to 5 V range: Values < 0.8 V or > 5.2 V are assessed as cable open circuits.
There is no underrange/overrange. Picklist: no,
yes
NAMUR NE43: Switch monitoring of the 4 to 20 mA range as per NAMUR
Recommendation NE43 on and off. The following error ranges apply when NE43 is
switched on:

3.8 mA: underrange (display shows: vvvvvv)

20.5 mA: overrange (display shows: ^^^^^^)

3.6 mA or

21.0 mA: open circuit (display shows: – – – –)
Picklist: On , Off
On Error : Specify the value the unit should continue to use (for calculations) if the
measured value is not valid (e.g. cable open circuit).
Picklist: Last Valid Value, Range Start, Meas. Range End,
Value is Invalid , Free
Configuration
Error Value: only if "Free Configuration" is selected for the error.
The unit continues calculating with this value if a fault occurs. Factory setting: 0 %
