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.
RLO
Lowest Dump Rate of Regrind (Grams/Second)
(Probably no need to ever change this)
RLO is the lower limit for SETTING the regrind thumbwheel switches. Settings lower than
this number will be held to the low limit. Air operated dump valves are not intended to
dispense very small quantities. We have set RLO at the factory to 5 percent (00050)
allowing a minimum dispense of 5% or about 100 grams.
LT1
LT2
Loader Timeout #1, Loader Timeout #2
LT1 and LT2 (set ONLY if your controller is modified to control a loader)
The LT1 and LT2 parameters are normally set to all zeros, indicating that this feature is not
present on your system.
If you have additional outputs on your WSB controller for driving a loading system, then this
parameter should be set to some number indicating how many seconds you will attempt to
load before sounding the ALARM. A sensor input to the controller tells the loader to load.
When the sensor is covered the loader stops. If the sensor is not covered within the
specified number of seconds, the strobe light and the beeper are activated and the display
