total weight just reaches the ‘batch weight’ by the time the system has come to a complete stop.
Flowrate
Q2333 flowrate 8762 t/h,kg/h
Displays the flowrate.
Q2336 dynamic filter [0=off,1=low,2=medium,3=high] 8298, g6 0
Additional flowrate filtering. Does not affect the control loop settings.
Large signal fluctuations are filtered less than small signal fluctuations. It is better turned off for
batching applications. See diagrams following.
Q2337 flowrate filter [0s, 0.5s, 0.7s, 1s, 1.4s, 2s, 3s, 5s, 7s, 10s, 14s,
20s, 30s, 50s]
8308, g6 0
Additional flowrate filtering. Does not affect the control loop settings.
Averages out fluctuations in the flowrate. The amount of filtering does not depend on the signal ampli-
tude. See diagrams following.
Q2338 flowrate raw 8764, g6 t/h,kg/h
The flowrate before the dynamic filter and flowrate filter.
Totaliser
Q2341 low flow cutout 8310 2.0 %
Totalising stops when the flowrate is less than this value.
If a negative value is used, then the low flow cut out occurs within a band. For example, with a setting
of -2%, totalising will stop when the flowrate is between -2% and +2%.
Q2342 totaliser division 8312 0.02 kg,t,g
Set the resolution of the totaliser.
Q2343 pulse output division 8314 0.02 kg,t,g
Set the resolution of the external totaliser.
Q2344 total weight 8730 0.00 TU
Displays the weight totaliser. The total is retained after a power failure.
Q2345 running total 8732, g6 0.00 TU
Displays a running weight total. This total is not reset by the RESET TOTAL operation.
Q2346 totaliser digits 8320, g6 6
Sets the number of digits the totaliser counts to.
Q2349 running time 8728, g6 h
The total time the system has been running. Accumulates anytime the ‘low flow cutout’ is off.
Limits
Limit 1
Q23511 limit 1 source (modbus address of signal) 8350, g7
Set this to the modbus address of the signal that will be compared with the setpoint.
Q23512 limit 1 mode 8354, g7 high limit = 0
Sets the limit operating mode.
