
PRC No change required
PRC is the maximum allowable PERCENT rate change per cycle. If a large dispense error
occurs, flow rate corrections do not exceed this percent number. This prevents large
swings in timing of dispenses and provides for stable dispense rates under difficult
conditions. For example, when dispense quantities are exceedingly small (one or two
grams), overfeeding by several grams is a distinct possibility. This type of error represents
an exceptionally large percentage error to the controller.
However, a large correction would not be appropriate but, instead, would cause a "hunting"
of dispense time that would result in further large errors. This parameter prevents this.
STL
No change required
STL is the TIME period allowed to pass after a dispense has occurred, but before a weight
reading is taken. This settle time allows falling pellets to reach the bin and prevents their
impact with the bin from adding to the weight reading.
LCL
LCH
LCF
LCZ
DO NOT CHANGE THESE
These four parameters are set to match the characteristics of the type of load cells used in
your system. DO NOT ALTER THEM. LCL and LCH are the acceptable LOW and HIGH
limits of load cell output expressed as raw signal counts per gram of weight. LCF is the
lowest acceptable FULL scale load cell output expressed as raw signal counts per second.
LCZ is the highest acceptable ZERO scale output. LCF and LCZ values are multiplied by
256 before being used by the software.
DS1
DS2
DS3
Function in Dispenser mode only.
Override top, middle and bottom thumbwheel switch settings.
When the system is operating as a dispense system, (FUL 00001), the dispense weight is
retrieved from the top thumbwheel switch or from the recipe file if the middle thumbwheel is
set to a recipe number.
If either DS1, DS2 or DS3 is set to any value greater than zero:
Substitute DS1 for the TOP switch settings,
Substitute DS2 for the MIDDLE switch settings, and
Substitute DS3 for the BOTTOM switch settings
These three parameters allow MLAN to download the dispense weight amount or recipe
number. They also allow entry of a "locked in" amount or recipe.
If BOTH DS1, DS2 and DS3 are set to 00000, then nothing changes.
The middle thumbwheel switch setting for a recipe will override the top switch setting.
When loading a weight into DS1, load 00000 into DS2 to be sure DS1 will control.
SCR
Special Customer Request
If a customer has a special software requirement that has no benefit to anyone else, then
this request is hidden in the software and activated by the appropriate code number being
entered into this parameter. Generally, these requests are useless to anyone else.
