Pulsed Output may also assist in dispensing regrind and some powders when these
materials tend to bridge. A parameter of 00501 will produce a 1/2 second open time (5/10
seconds), a long enough time to allow a significant dispense, followed by a 1/10 second
close time, just enough to close the gate fully. The rapid gate movement may help in
keeping material flowing.

SE Upper Limit - Use to lock out high settings or limit access

_SE is the upper SETTING limits for this component. This allows a reasonable cap to be
set for each component so that an operator cannot accidentally set the controls to an
excessively high setting. For additives, these limits will ensure that expensive material is
not wasted. Settings that are greater than the limit are held to the limit.

EXAMPLE: If the highest color usage in your plant is 6%, then you can enter this upper
limit in the parameter table. Since settings are stored as 1/10's of percent (##.#), the
parameter would be:

_SE 00060

Any setting above 060 is held to 6 percent.

When a 1 is entered as the first digit of this parameter, (_SE 1xxxx), setting entries can
only be made from the program mode. In this way access is limited to only those who know
the password.

XT Format - Allows a setting entry of less then 00.1

_XT, is a number that will alter the value of the setting that you enter. The value of the XT
parameter, is divided into the setting, thereby reducing the setting's value. The only valid
entries are 10 and 100. When set to "00010" the decimal point is moved to the left one
place and the setting is read as X.XX percent. When set to "00100" the decimal point is
moved to the left two places and the setting is read as .XXX percent. This allows closer
control where a requested dispense is less than 1 percent. When set to "00000", this
parameter has no effect.

Limit Adjustment - Changes itself automatically over time

_NC is the allowable GRAM error within which NO flow rate corrections are made by the
software. Gram weight errors that are equal to, or less than, this number will be accepted
and no error corrections will take place. Since no equipment is perfect, we must accept
that a certain range of error is normal. To make corrections within this range only adds an
additional error due to hunting, and broadens the error range. This parameter is adjusted
automatically by the software according to the actual conditions of the metering.

This number has been set based on our experience with the dispense devices. If, over
time, the computer finds that the number is too large or too small, it will automatically adjust
it to match the actual conditions that exist with your equipment. These adjustments occur
in increments of 1 or 1/10 gram and occur only once every 20 cycles. A change is made
only if needed. Checking this number from time to time will indicate the normal error range
that is occurring with each dispense device on your unit.
