to accomplish a particular task, can be easily added.
System can be expanded by adding modules, a larger rack or additional racks.
Modularity aids trouble shooting. Allows easy, module swapping style
trouble isolation. Gets your system up and running quickly.
Simple Rack Mount
Reduces Installation Time & Cost.
Plug in connections on modules eliminate manual wiring.
Can be installed where you want, at the feeder or in remote control loca
tion.
A wide variety of enclosures (NEMA 4, NEMA 4X, etc.) are available.

Rack Size Can be Selected to Suite Application
4 or 6 module racks can be selected to tailor the EZ-3200 to meet present
requirements and to anticipate future requirements.
One Power Supply Per Rack
The PS-2 module distributes power to all modules in the rack. This simpli
es module construction.
Each Rack Back Plane has an Internal Bus
Allows fastest communication between modules in the rack.
The bus makes information available in any one module available to all
modules.
Easy to Add Rack System
Adding racks reduces the burden on any one system processor (for fast
system response).
Adding racks allows isolation of control architecture. Individual lines can
be run independently while trouble shooting another.
Hand Held Programmer (HHP-1)
The HHP was developed to provide an easy to use opera-
tor interface for the EZ-3200 series of instruments. When
connected to the utility port of an EZ-3200, the HHP-1
allows application contained within the EZ-3200 to be pro-
grammed, monitored and controlled.
Graphics Display Panel (GDP) The GDP is an intelligent operator interface spe-
ci cally designed to work with the advanced line
of EZ-3200 instrumentation developed by Thayer
scale. Once properly con gured and attached to a
THAYER net II communication network, the GDP
can be used to calibrate, control, monitor and per-
form diagnostics routines on virtually any device in
the network. The large backlit LCD display screen
makes viewing the information very easy.
The Thayer EZ 3200 is a multi-processor controller speci cally designed for weigh feeder applications. It consists of a
family of modules that can be combined in many ways to suit a variety of applications. The control is performed by general
purpose and special software running on the EZ-3200 modules and communicating over a Local Area Network (LAN) to
provide many possible con gurations for local and distributed systems.
The basic EZ 3200 consists of a card cage (rack) with a Power Supply (PS-2) and an Application Processor module
(AP32HS) which can support several other plug in modules. An essential module for each weighing device is the Scale
Signal Processor (SSP). In addition to the circuitry for energizing and reading the scale transducer, it provides a limited
amount of I/O to accommodate a single application. General purpose I/O modules can be installed to provide additional
input and output signals of various types.
Multi-tasking, Hi-speed Integrator/Controller for Single or Multiple Continuous Weighing, Feeding & Metering Applications
A Four Slot Rack can be con gured to run one or two Weigh Belts, Belt Scales or Loss In Weight Feeders depending on
I/O Requirements.
A Six Slot Rack can be con gured to run one or up to four Weigh Belts, Belt Scales or Loss In Weight Feeders depending
on I/O Requirements.

COMMUNICATIONS
The AP 32HS Host port provides a means for external devices (hosts) such as
programmable logic controllers (PLC), computers or distributed control systems to
exchange information with an EZ-3200. This port supports both RS-232 point-to-
point and RS-485 multi-drop operation. The application software running within the
AP32HS determines the type of information that is available.
The EZ-3200 O/I
Provides an easy
to use operator
interface for the
EZ-3200 series of
instruments. It is
used to calibrate,
control, monitor and perform diagnostics
routines on any device in the module rack.
