causes hunting. Larger is safer since you do not want "false" adjustments to occur.
This parameter starts at XTP 50030, 30 percent of full batch weight accumulated error and
5 cycles required without adjustment before your operator can switch to the Throughput
mode. A "T" is displayed when the 5 cycle requirement is reached.
XAL
Extrusion Control Adjustment Limit
XAL limits the degree of change that the software can make in one adjustment cycle.
Default setting is 00005, 5 percent. Operator entered rate changes are not limited.
XUL
Extrusion Control - Upper Adjustment Limit
XUL sets an upper limit to how far the software can adjust the extruder speed (control
voltage). If this limit is exceeded, then the adjustment is NOT made, and the ALARM is
turned on. Pressing the V/T key switches the control to Voltage Mode. When pressed
again, the unit returns to Throughput Mode, and a new Limit is set. Further adjustments
may now occur to the new limit.
Default is 00200, 2 volts. The idea is that once control is established, adjustments upward
of more then 2 volts indicate conditions that should be attended to, a clogged screen pack
for example. You may wish to reduce this number so that operators are warned well in
advance of such conditions.
CPL
Yield Control - Counts Per Linear unit of measure
Customers using Yield Control require a pulse generator, or shaft encoder, mounted on
downstream takeoff equipment to signal the line speed to the blender. In operation the
software displays GRAMS per unit length, which may be per foot, per yard, per meter, or
whatever. For whichever unit length you select, enter the pulses per unit length in this
parameter. In America, a typical shaft encoder delivers 600 or 1200 pulses per foot. Set
the parameter to 600 or 1200. Everywhere else you are most likely concerned with meters.
The proper setting for this parameter is then the number of pulses per METER that the
encoder generates.
PTD
Yield Control - Pulse Train Delta, trip point
This allows some error in the pulse train rate. For example, if the pulses are being
generated at a rate of 6030 per minute, which is 100.5 per second, and we count pulses
every second, then we will count 100 for one second, 101 for the next, then 100, then 101
and so on. This "error" could cause adjustments to occur when no adjustment is warranted.
The PTD parameter specifies how many over or under pulses have to accumulate before
adjustment occurs. In the above example, if 6030 per minute was what we wanted, but
counts came in at 101 per second, then an error of 30 would accumulate in 1 minute. The
PTD parameter set to 00030 would cause a correction to occur at this level of error. The
default value of this parameter is 00060 (20).
MPO
For Micro Blender air driven reciprocating mixer.
MPO sets the timing, in tenths of seconds the clockwise and counterclockwise timing of the
mix blade. MPO 00010 is 1 second for each direction.
LIQ
For LIQUID COLOR applications using dual pumps / drums.
Liquid Color users generally want the current container of color to run completely out
