The 9 or 14 digit representation type is selected in coordinate LK29 No. of digits.
Note
Attention : With conversion to a different unit, the totalizer increment is
calculated with the new unit and added to the previous total-
izer status, creating
Mixed values
.
Therefore, resetting the totalizer is logical after a conversion.
In addition, it is also possible to shift the decimal separator and select the "Totalizer
status" representation * 10 (100, 1000) m³.
In coordinate LK22 Counters mode , the
operating mode of the main totalizers is adjust-
ed in case of an fault:
"Stops" = main totalizer stops in case of an alarm
"Runs" = main totalizer continues to run in case of an alarm
(in addition to the disturbance totalizers)
“MID” = t he totalizer totalizer with volume at base conditions and energy flow stops
with an alarm. The volume at meas. cond. continues with an alarm, insofar
as the volume transmitter is not affected by a failure. If there is a failure of
the pressure or temperature sensor, the volume at meas. cond. continues,
and the volume at base conditions stops. Therefore, retroactive accounting
is possible, but it can be very elaborate. Therefore, this selection is not
preferential and is unusual.
When the value in coordinate
LK23 Max. accumulation input pulses which have not
been converted (i.e. too many intermediately stored pulses with open calibration
lock), a message is output:
W05-7 Pulse batt>max.
The determination method for the channel status of the totalizers (DSfG function) is
defined in
LK26 Channel status method :
a.) RMG traditional
b.) New definition according to Ruhrgas
with
Method a.) , all stationary counters have the stopped status, regardless of
whether there is a fault or another route. Only the running counter has the okay sta-
tus.
