Chapter 4 – General Configuration
Firmware Version 3/4.31.37
Blnd Chk Restart Vol
(Excluding SMP & SCS)
Blend Check Restart Volume applies to ratio blending only. After the volume
specified in this parameter has been delivered, the system will start checking the
ratio of the blend. This parameter is intended to give the flows from the multiple
meters an opportunity to stabilize after a restart from zero flow. Blend ratio checks
will not resume until after this volume has been delivered. This setting should be
configured to be greater than the Low Flow Restart Volume, so that checks can begin
after the transition to High Flow.
Blnd Chk Alarm %
(Excluding SMP & SCS)
Ratio Blending-Blend Check Alarm %. When the ratio is found to be out of tolerance
by the percentage specified in this parameter, loading will stop and an OVR BLEND
or UND BLEND alarm will be raised. The alarm will occur when the percentage error
has lasted for the period specified by the Blend Check Alarm Time parameter.
Sequential Blending-In sequential blending applications, this parameter can be used
to raise an alarm when the blend composition is out of specification at batch
completion. If, upon completing delivery and clearing the totals, the ratio of any
component of a sequential blend is out of specification by the value entered in this
parameter, an OVR BLEND or UND BLEND alarm will be raised.
Blnd Chk Alarm Vol
(Excluding SMP & SCS)
Ratio Blending-Blend Check Alarm Volume. When the ratio is found to be out of
tolerance by the volume specified in this parameter, loading will stop and an OVR
BLEND or UND BLEND alarm will be raised. The alarm will occur when the volume
error has lasted for the period specified by the Blend Check Alarm Time parameter.

parameter, an OVR BLEND or UND BLEND alarm will be raised.
Blnd Chk Alarm Time
(Excluding SMP & SCS)
Blend Check Alarm Time applies to ratio blending only. When the ratio is found to be
out of tolerance for the time period determined by this parameter, loading will stop
and a blend ratio alarm will occur. Enter time in seconds.
Low Flow Start
Percentage
Calculate from the entered preset amount the low flow start volume. This volume will
only be used when it is larger than the Low Flow Start parameter. This calculated
volume will not exceed 65,535. The low flow restart value will not be calculated using
the preset value.
Blnd On Lead Comp.
(Excluding SMP & SCS)
Blend on Lead Component applies to ratio blending and side-stream blending only.
Enable this parameter to have all other components track the flow rate of the lead
component. The lead component is defined as the first component listed in the
product recipe. The product recipe is provided to MultiLoad by Terminal Automation
Systems (TAS), such as TMS5/6. This feature should be used when blending viscous
components, such as asphalt. The lead component should be the component that is
expected to be the limiting factor in achieving maximum flow for the blend. The lead
component can be limited by inconsistent pump pressure, for example. (v2.25)
The leading component can be defined on three ways:
FIRCOMP: First component defined in the recipe
HIGPERC: The highest percentage of the components defined in the recipe
LOWPERC: The lowest percentage of the components defined in the recipe
