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).
G2F
The G2F parameter is used in conjunction with the G2 Software or the Get Totals
command. The Get Totals MLAN command can be sent with either a command code of 16
or 17. If Get Totals used command code 16, an internal flag in the controller is set
indicating the totals have been collected for this cycle. If the G2F Parameter is on, the
blender will stop running cycles and alarm because the flag had not been set, indicating the
totals had not been collected for the previous cycle. At that time the "Get Status" MLAN
protocol command will return an alarm status of 26.
XMO
Maximum Extruder Output
For Extrusion Control, this parameter stores the extruder throughput rate that can be
expected when control voltage is set to it's maximum output of 10 volts. On start up, before
the unit has time to learn the correct voltage/throughput relationship, this parameter is used
as a starting point. Having this value allows the customer to switch to Throughput mode
right away; no need to wait several cycles. XMO is adjusted and corrected frequently by
the software to match your process. The only time it is zero is on the very first start up of
the system. XMO is the rate in pounds per hour, or kilos per hour.
LTP
Loss In Weight Trip Point
For Extrusion Control, Yield Control, when a Loss In Weight station is part of the system,
an adjustment "trip point" must be specified. This is the total accumulated error that is
required to cause an adjustment to the learned rate. This is the equivalent to the XTP
parameter, which is explained earlier. The last 3 digits are a percentage in tenths (xx.x) of
the total batch that is being monitored. If the system is filling the Loss In Weight bin to a
total weight of 10,00 grams, for example, and allowing it to drop to 4000 grams, for
example, before refilling, then the batch is 6000 grams. If LTP is set to 00010, then this is
1 percent of 6000, or 60 gram trip point. See XTP for more explanation of trip point.
LLF
Loss In Weight Low Level Fill
Value in grams that will cause the fill valve on the Loss In Weight system to open and
begin to fill. This parameter is set automatically by the *22 LIW Model Selection.
HLF
Loss In Weight High Level Fill
Value in grams that will cause the fill valve on the Loss In Weight system to close and stop
the fill process. This parameter is set automatically by the *22 LIW Model Selection.
SBO
Sensor Blow Off
If SBO is set to a value, the Weigh Scale Blender will pulse the FCV valve by a specified
pulse length and specified delay in between pulses for the purpose of clearing dust and
particles from the face of the sensor. The pulse length is set by the value in the 1st digit of
the SBO parameter. The 1st digit for pulse width is in .1 seconds (1/10
th
second intervals).
After the pulse, there will be a delay to the next pulse based on the value set in the last 2
digits of the SBO parameter. The last 2 digits for the pulse delay are in seconds. If the
SBO parameter has been activated by entering values, the pulses will operate for a
maximum of 20 times as long as the sensor remains covered. Recommended SBO
parameter setting is 10030, which would pulse a 1/10
th
second pulse every 30 seconds.
