overfeeding by several grams is a distinct possibility. This type of
error represents a very 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 also prevents their impact
with the bin from adding to the weight reading.
======================================================================
LCL, LCH, LCF and 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 Function in Dispenser mode only.
Override top and middle 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 or DS2 is set to any value greater then zero:
substitute DS1 for the TOP switch settings, and
substitute DS2 for the MIDDLE switch settings.
These two 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 and DS2 are set to 00000, then nothing changes.
Note: 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. Believe me when I say that these requests are useless to
anyone else.
