To Our Customer
Thank you for purchasing the Dryer MasterAM3(Automatic Mini Moisture Manager) System. The
Dryer Master AM3 is a robust system that employs state logic for control. It is simple to use and can be
applied to most if not all grain moisture measurement applications.
The AM3is part of the Dryer Master family of moisture monitoring and moisture control systems that
have at their heart Dryer Master's stainless steel fin type capacitance based moisture sensors. These
sensors were initially developed to drive Dryer Master's industry leading computerized moisture
control systems, where they are placed at the inlet and the outlet of the dryer. With over 30 years of
field proven experience they are now being offered as part of the AM3moisture monitoring and state
logic control solution.
We trust that you will be pleased with the operation of the AM3and that you will enjoy benefits similar
to those provided by the world renowned Dryer Master

moisture control system.

1. Introduction
This document provides the operational specification for an on-line moisture display system with a
single sensor; product moisture and product temperature are displayed. Moisture control is achieved
using state logic. The system consists of a display unit and a moisture sensor. Both the display unit
and the sensor require less than 15 watts of power and are powered from a low voltage 24-volt direct
current instrumentation power supply. Depending on the options purchased the system may include
other components and devices.
Moisture measurement technology
The Dryer Master Moisture sensor measures the dielectric properties, in effect the capacitance of the
product in the vicinity of the sensor fin. This method is the most effective in measuring the total water
in a given volume of product. The installation ensures a large sample of product is presented to the
sensor at all times. This large sample contributes to a better product moisture representation than
other methods and generally provides a very good representation of the product in the total sample
stream. This technology is particularly suited to the measurement of product with moisture gradients.
A moisture gradient occurs any time product is processed either by heating or cooling but not limited
to either. The sensor’s robust construction and conservative installation specifications ensure long
product life.
Moisture control technology
The Dryer MasterAM3 state control technology employs a 3 state model triggered by user settable
moisture targets, time delays and speed set points for continues dryers. Instead of constantly
switching between a high and low discharge speed as used in many smaller on farm drying systems the
system switches between higher discharge speed triggered by drier product to normal speed, to lower
speed triggered by higher moisture product. Depending on the operating mode the 3 speeds can be
either individually manually set, set as a % of the normal operating speed, or a specific deviation from
the normal speed. The trigger points are actual moistures measured by the moisture sensor and
delays to activation are user settable from 1 second to 999 seconds or 16.65 minutes. The system can
also be configured for recirculation batch type dryers. Where the product is re- circulated in the dryer
until a specific moisture target is reached and the dryer is unloaded.
Information display
The information display is a micro PLC (Programmable Logic Controller) with an integrated graphics
LCD display and keypad. This combination of integrated items is also referred to as an OCS (Operator
Control Station). The Dryer Master Moisture sensor calibration software embedded in this device
provides the same reliability and accuracy previously once only available in the Dryer Master dryer
control systems.

1. The Display unit is the information provider. Product
moisture, product temperature as well as alarms and moisture
trends are information continuously displayed. Product
selection, Discharge Rate settings, as well as sensor calibration,
alarm function and system setup are all functions accomplished
through menus accessed via the key pad and Action Keys. The
display has a screen saver that shuts down the back lighting to
prolong lamp life.
Figure

–Information display
2. The Moisture sensor is the heart of the system. The sensor is
located in what is called a compacted product flow situation. This is
a chute where the product is slowed and allowed to compact. The
sensor measures the free water in the product in this chute. Even
and consistent product flow is key to obtaining stable moisture
readings.
Figure
4.
–Fin Moisture sensor
3. The enhanced system adds an enclosure for the
display unit, easy to connect terminals and a universal
voltage system power supply to power both the Display
and Moisture sensor. The supply may also be used to
activate low voltage low current alarm devices or alarm
contacts. On systems equipped with a Dryer Master
Power supply the unit is capable of supplying 24Volts DC
at up to 1 Amp and is current limited and designed to
shut down in the event of a short circuit.
Figure
5.
–Information display in enclosure
4. The optional industrial grade point of sale terminal printer provides hard copy records of
operation with a record printed every 10 minutes.
5. A calibrations pushbutton may also be used. This illuminated push button when installed
and configured can assist moisture calibration by automating this function. When so
configured the system will gather and average the moisture passing by the sensor during the
period the button lamp is flashing, and then remain lit until the calibration result is entered.
6. Alarm outputs with time delay settings can be used sound alarm devices and or trigger
events.

3 System Operation
This section will deal with the most common items needed to operate the unit. Included is a screen
map of the various screens displayed during start up and operation when alarm conditions occur,
continuing on to product selection and sensor calibration. Also included in this section are common
setup functions such as alarm limit settings, alarm action settings and common system settings. The
detailed Engineering and device setup functions will be described in another section.
3.1 System displays
This is a Touch screen system. Throughout this document there may be references to “Touch Keys” or
“Touch areas” which refer to values or text on the LCD display. These “Touch Keys” or “Touch areas”
will access various functions as you navigate through the screens & menus. The Display may also be
referred to as a PLC (Programmable Logic Controller) or an OCS (Operator Control Station).

4 Operating the Dryer from the AM3
This section will describe how to operate the dryer from the AM3. The modes of operation are
reviewed as well as an in-depth description of the 3 modes of Automatic. This section assumes the AM3
has already been calibrated and set up to work with your dryer. Refer to the section “The Menu Tree”
to set up the various alarm settings and especially the rate output setup in the engineering section.
4.1 Operating the System
At start-up the system will boot to this current operation or main screen. While in manual mode the
rate set point will display whether the dryer is running or not.
4.1.1 Main Display –Local Mode
With the dryer running and discharging product you will see a moisture reading, the product
temperature, and the rate is displayed if in “Manual” or Automatic” mode. There is no feed back so we

Press the “Touch area” <Rate: > to display dryer discharge speed
“Rate” entry screen.
Press the “Touch area” <Auto Setup>to adjust or modify the
