Weight
Basic weight
Q23111 gross weight 8740 kg,t,g
Displays the gross weight.
Weight zeroing
Q23121 zero range 8212 2.00 %
The maximum range as a percentage of the Weight Capacity over which a zero may be acquired. This
restricts the operation of both an operator initiated zero (pressing the ZERO key) or an automatic zero
when the zero tracking band is enabled.
Q23123 zero band 8216, g5
13
0.5 divs
Defines the zero band either side of zero. A setting of 0 sets a band of ± ¼ of a division. If set to
0.5kg, the zero band is between -0.5kg and +0.5kg This setting effects the automatic zero tracking if
enabled.
Q23125 auto-tune progress 8752
Displays the percentage progress through the auto-tune cycle.
Q23126 zero weight 8220 kg,t,g
Displays the amount of weight that has been zeroed out since the last zero calibration.
t
Batching
Q23211 batch setpoint 8400, g7 0.00 TU
Set the target ‘batch weight’ here.
Q23212 batch preact (stop this amount before batch setpoint) 8402, 0.00 TU
Stop when the ‘total weight’ is this amount before ‘batch setpoint’. Set the ‘batch preact’ so that the
total weight just reaches the ‘batch weight’ by the time the system has come to a complete stop.
Flowrate
Q2332
flowrate disturbance hold (set to 0 to disable) [0 to 1000]
8292 0 %
Sets a threshold to changes in weight when the flowrate is held constant. The flowrate is normally
expected to be within the band of 0 to the flowrate capacity. This setting sets a band beyond these
limits which if the flowrate exceeds, the previous flowrate value is held.
Q2333 flowrate 8762 t/h,kg/h
Displays the flowrate.
Q2334 simulator [0=off, 1=simulate flow] 8294 0
Usually Off. Simulates a flowrate for testing purposes.
Q2335
flowrate response [10s, 14s, 20s, 30s, 50s]
8296, g6 normal=1
Sets the how quickly the flowrate is determined. For systems with a small weight change signal, the
flowrate may be more stable when this setting is higher, but it will take longer to reach a steady
flowrate reading.
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.
13
Set in divisions of weight, the smallest weight increment as displayed when setting the weight capacity or weight divisions. [0.5 to 12]
