The settling time is the time after a component dispensed into the weigh bin, while
multiple weight reading are taken. (This time allows the material to settle and the
load cells to recover from the dumping process before the final weight reading is
taken.) The time should be entered in milliseconds For example, in the above
screen shot 1500 milliseconds is entered which equals 1.5 seconds. For most
Trueblend applications the default time of 1500 milliseconds should be
acceptable. In retrofit applications where slow screw feeders are used these times
may need to be increased to allow the material to drop from the feeders.
B. Batch times
Batch Settling time
– The Batch settling time is the time prior to beginning a
batch, where the blender waits for the weigh bin to settle and return to the tare
weight.
Weigh Bin Open time
– The weigh bin open time is the time that the weigh bin is
actually open as the material is dumped into the mixing chamber.
Second Dump time
– The second dump time is the length of time that the weigh
bin opens a second time to knock off any additional material that may remain in
the weigh bin. This feature is used on the TB45 and TB100 blenders.
Flow Control Valve time
– The flow valve time is the time that the material valve
under the mixing chamber is open to allow the material to exit the mixing
chamber. (When this option is included)
