17.1 Introduction
One of the applications for which the 550 is very well
suited is the operation of Truck Weighing. The 574 is
not normally used in truck applications but it still has the
capabilities to do so. This application takes into account
the two most frequent situations; dumping or pickup. In
Truck dumping, the initial weight of the truck coming in
(Truck In) is heavier than when the truck is leaving
(Truck Out). In Truck pickup, the initial weight of the
truck coming in (Truck In) is lighter than when the truck
is leaving (Truck Out).
The Truck In / Out capability makes use of the <ID> key
to permit entry of truck identification (ID) numbers. The
ID's are stored within the system with the incoming
weight of the truck. When the truck is on the way out,
the In-Weight is compared to the Out-Weight. The
instrument then considers the lower of the two weights to
be the Tare Weight, the larger to be the Gross Weight,
and the difference to be the Net Weight. Tare Weights
may be permanently stored in the system to determine
truck weights with a single weighment. One or more of
the Custom Transmits may be sent, providing either a
ticket documenting the amount of weight picked up or
dropped off, or sending the data to a computer or remote
display. This feature makes the instrument an ideal
weight unit for dump site weighing, gravel pit weighing,
and many other truck weighing applications.
This feature includes the ability to establish and store the
tare weight of a vehicle, clear any or all stored weights
or transmit the currently stored truck weights.
The Truck In/Out feature works in a relatively preset
manner. It can be customized to some extent with its
setup, and even further with the use of macros. However
if complete customization is required then the Database
Option should be implemented and the operation can be
designed to perfectly fit the intended application.
Incompatiblity:
When Truck In/Out operation has been selected, the
Macro Menu feature and the Database Option are not
available.
17.2 Setup
Enabling Truck In/Out Weighing:
To enable the Truck In/Out feature, parameter P720 is
set to selection 1, "ID use: Truck". Selecting this
feature causes the subsequent setup parameters, P721 -
P725, to become accessible. The available choices for
P720 are documented in Table 30 Parameter P720 ID
Use Selections.
Selecting ID Type:
Four different types of Truck ID's are selectable with the
Truck In/Out feature. The differences between the types
is primarily in the size and type of characters which may
be used for the ID. Based on the needs of the
application, choose one of the four types as described in
Table 31 Type of ID P721 Selections.
Also, be aware that the larger the number of bytes per
row, the lower the total number of truck weights which

Description
(Specifies the use of the <ID> key
from the weigh modes)
The ID key is used only to
access the six ID parameters.
(Refer to chapter 14 on ID's).
Enables Truck In/Out
Weighing. (Required for
Truck In/Out Weighing).
Allows 'named macros" to be
selected and invoked with the
ID key. (Refer to chapter 16
on methods of invoking
macros).
Causes the database command
menu to be displayed. This
choice is available only if the
database option module is
installed. (Refer to chapter 20
on Databases).
