rate he desires sooner, and the blender can immediately make any required adjustments
required to target in on this rate. Too large a number causes delayed response, too small
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.
XCV
XRC
Extrusion Control Voltage
(For Extrusion Control Systems only)
XCV - "Extruder speed Control Voltage" is used in conjunction with our extrusion control
software. This number can range from 0 to 1000 (XCV 00000) to XCV 01000), and
determines the voltage output on pin S of the Amphonol connector. Pin R is the neutral or
zero reference for this voltage output. The voltage ranges from 0 to 10 volts. 01000 =
10.00 volts. This parameter can be set manually, however it is intended to be controlled by
the extrusion control logic or by MLAN communications in conjunction with our extrusion
control software. Whenever the software control logic makes a change to this voltage, up
or down, the controller display will say (RAMPING) during the time the voltage is being
adjusted.
XRC - "Extruder speed Rate of Change", determines the ramp up or ramp down rate of the
XCV parameter, above. It can range from 0 to 10 (XRC 00000) to (XRC 00040). Default
setting is 00040.
When XCV changes, it does so gradually, making small incremental changes every 10
interrupts, or about 24 incremental changes per second. The XRC parameter determines
the maximum value of each incremental change. For example, if XRC is set to 1 then the
XCV number will increment by 1 count (0.01 volt) every 10 interrupts, for a rate change of
24 counts (0.24 volt) per second, which will produce a full range change from 0 to 10 volts
over about 41 seconds.
TCV
TRC
Takeoff Control Voltage
(For Extrusion Control Systems only)
These parameters control a second 0 to 10 volt voltage output on for controlling Takeoff
control speed. They operate the same as the XCV and XRC covered above except they
move in the opposite direction, higher to reduce weight per foot, lower to increase weight
per foot.
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
