What is in this manual
Introduction
Drying is one of the most difficult processes to control. It requires constant attention to moisture,
temperature, volume and throughput. The DM510 is ideally suited to these operations. It devotes
its full time to your dryer. The DM510 is a tool that helps the operators, by doing the menial tasks
and frees them to make the executive decisions about the drying process. It should be noted that
the DM510 Dryer Master only optimizes the dryer’s performance.
A good understanding of the drying process helps a great deal in understanding how the DM510
works.

Operations Manual
DM510 - A Brief Description
The Dryer Master DM510 from DMSI is the ideal addition to your new or existing continuous flow
grain dryer. Simple and easy to operate, the DM510 uses advanced process control to automatically
adjust your dryer discharge rate, drying grain more consistently and closer to your target moisture
level.
The DM510 is a computer control system that controls grain drying. The system comes complete
with an operator panel, sensors to measure the grain moisture and temperature entering and
exiting the dryer, a drying air temperature sensor, a printer and remote access via internet
capability. The system uses this and other information, to set the optimum grain discharge rate to
control the moisture of the product within a narrow tolerance.
The DM510 is capable of being monitored and controlled remotely through a web browser on your
smart phone, tablet or desktop PC through DM-Mobile. Simply connect the DM510 to an internet
enabled router and then access many of the DM510 functions through your web browser at
my.dryermaster.com. DM-Mobile can also be configured to provide you with text on alarm
messages so that you can be aware of an issue without having to be at the DM510 panel.
The DM510 provides quick payback by reducing over and under drying resulting in increased yields,
energy savings, and providing a better quality dried product.

Dryer Master DM510
Operations Manual
DM510 - How it Works
As an operator you know that grain drying is a very difficult process to control. You know that your
dryer dries faster or slower depending upon drying conditions. Ambient air temperature, wind
speed and direction, humidity, time of day, the variety of the grain being dried, and of course, the
moisture of the grain all can affect dryer operation.
The Dryer Master DM510 uses sophisticated on-line moisture measurement and moisture control
technology to overcome these difficulties. The DM510 uses specially designed on-line moisture and
temperature sensors located at the inlet and the outlet of the dryer. These sensors provide
continuous moisture and temperature readings to the computer located in the DM510 control
panel.
The computer uses this information to build an operating model of your dryer. As inlet moistures
and drying conditions change throughout the day the DM510 continuously calculates and
automatically adjusts to the optimum discharge rate for current conditions.
The DM510 has two important advantages. First in automatic mode it can continually watch the
dryer. It does not have to help unload trucks, load trains, or do any other jobs around the elevator.
The dryer receives its full attention.
Second it has the benefit of continuous moisture information from both the inlet and the outlet of
the dryer, giving it a complete picture of all the grain in the dryer, and the grain exiting the dryer.
With this information, the DM510 does not have to wait to react to changes in the outlet moisture. It
is able to adjust the discharge rate as the incoming moisture changes. For example, as wetter grain
comes into the dryer, the DM510 begins to slow down the discharge rate just as the wetter grain
reaches the hot zone.
Access to our Customer Support Centre
One of the unique benefits you the operator receive with the DM510 is access to support from the
Dryer Master Support center where DMSI has experts in the theory (application to drying),
installation and operation of the DM510. Personnel are available to answer questions about the
material in this manual and other questions you have pertaining to drying. You can call the support
center toll free from the USA or Canada at 1-888-318-0009.

DM510 Control Panel including I/O:
The DM510 is a computer system complete with user interface keypad and the display screen, I/O
system and the capability to provide real time information through an internet connection to an
internet capable device. The DM510 Control Panel is typically installed in the control room close to
the dryer where it can be readily accessed by the operator. The I/O can be located remotely using a
wired connection for short distances or a wireless connection for longer distances (requires optional
wireless modems).
The Printer:
The DM510 uses the printer to provide reports such as: Continuous Averages, Hourly Summaries,
and Daily Summaries etc. These are tools that can be used to manage the total drying process.
Inlet Moisture and Temperature Sensor:
The inlet moisture and temperature sensor is installed in the flow of the product before it enters the
drying zone (hot zone) of the dryer, typically in the garner or holding bin above the hot zone.
Outlet Moisture and Temperature Sensor:
The outlet moisture and temperature sensor is installed in the product flow after it exits the dryer.
Calibration Push Button:
The calibration button is installed near the operator sampling point for product exiting the dryer,
usually in close proximity to the outlet moisture sensor.
Drying Air Temperature Sensor or Temperature Signal Converter:
A temperature sensor is installed in the heating chamber in close proximity to the dryer’s existing
drying air temperature sensor to monitor the drying air temperature. Some systems will instead use
a temperature signal converter to use the dryer’s temperature reading.
Internet Connectivity Capability:
Connect your DM510 to an internet enabled router or wireless hotspot (via Ethernet cable) and you
access your system remotely via a desktop PC, smartphone or tablet. Simply use your browser to go

Three Ways to Operate
The DM510 Dryer Master can be used in three ways, called Modes of Operation: Local, Manual, and
Automatic. It is very important that you understand the differences between the three modes.
Description of the Operating Modes
Local: Every time you start your dryer the DM510 begins in ‘Local’ mode. In Local mode, the
DM510 monitors the drying process and displays information on the screen, but it does not
control. In Local mode you operate the dryer from the dryer control panel just as you did
before you installed your DM510. Note the Ready status light is NOT illuminated.
Manual: In ‘Manual’, the DM510 monitors the drying process and displays information on
the screen, but it does not control. In ‘Manual’ mode you operate the dryer discharge rate
from the DM510.
In ‘Manual’ mode, you can conveniently change the dryer discharge rate directly from the
DM510 panel using the ‘Setpoint’ key. You will typically use ‘Manual’ mode at startup while
the DM510 is learning, or while you are drying short runs, once the Ready status light is
illuminated, you can switch to ‘Automatic’ mode.
Auto: ‘Automatic’ mode is where you want to be most of the time. In ‘Automatic’ mode, the
DM510 makes changes to your discharge rate automatically. These changes are based on
the process information it receives from the sensors and its model of your drying process.
When you switch to ‘Automatic’ mode, the DM510 will ask you for target moisture. It will
then automatically control the discharge rate to dry as much grain as close to your target
moisture as possible.
In ‘Automatic’ mode, you will find that your job as operator will become that of a supervisor.
You will be responsible for setting the target moisture for the DM510, for setting the limits
that it operates under and making sure that the moisture sensors are calibrated.
Important
DM510 systems with ‘Auto Fast Start’ enabled can be switched to Automatic
mode as soon as the DM510 determines the dryer is running. Should the DM510
select an inappropriate speed, return the system to Manual mode and wait until
the 'Ready' status light is illuminated before selecting Automatic.

Changing Between Modes
Changing between modes is straightforward. Press ‘Mode’ to display the mode selection menu.
Press the up or down arrow keys to highlight your selection followed by the ‘Enter’ key, or press the
number key for the selection.
Selecting ‘(1) Request Manual’ will forward you to the ‘Manual Mode’ ‘Rate Entry’ screen. Press
‘Cancel’ to accept the displayed value and return to the ‘Main Operations’ screen. Or type in a new
value followed by ‘Enter’ key to return to the ‘Main operations’ screen using the new rate value.
Selecting ‘(2) Request Automatic’ will forward you to the ‘Automatic Mode’ ‘Target Entry’ screen.
Press ‘Cancel’ to accept the displayed value and return to the ‘Main operations’ screen, or type in a
new value followed by ‘Enter’ key to return to the ‘Main operations’ screen using the new target
value.
Selecting ‘(3) Request Local (control at Dryer) will return to the ‘Main operations’ screen, switch to
manual operation at the dryer panel and extinguish the Remote Status light.
Choosing a Moisture Setpoint
The DM510 does two things based on the target moisture setpoint that you provide. First, it
observes the discharge moisture in relation to the target to create an image of the drying conditions
(dryer model) within the dryer. Second, while in Auto, it manipulates the discharge rate to dry as
much grain as close to target moisture as conditions allow.
When choosing target moisture, remember that the target moisture is average moisture, not
maximum moisture, some grain will come out wetter than the target moisture and some will come
out drier.
To change the target moisture, press ‘Setpoint’ to display the setpoint selection menu. Choose (2)
‘Moisture Setpoint’ to display the Moisture setpoint entry display. Enter new target moisture, press
‘Enter’ to accept the new value and return to the ‘Main operations’ screen.

Calibrating the DM510 Sensors
Reasons for Calibration
The DM510 controls your drying based on its moisture sensor readings. For proper operation it is
important that the DM510 (on-line) moisture sensors agree with your bench top (off-line) moisture
tester. This means that for a given sample of grain, both your bench top tester and your DM510
moisture sensor will give a similar moisture reading.
While it may sound straightforward to have the on-line DM510 sensor read the same as your bench
top unit, there are a few points that make it a little more complex.
The DM510 measures the moisture in slightly less than ¼ of a cubic foot (7 liters) of product, in corn
at 56lbs/bushel (that equates to about 10lbs (4.5Kg) of corn. The bench top sample is usually less
then 250 grams. It is possible to have bench top samples that differ significantly from the reading
the DM510 sensor provides. Differences in product temperature and the temperature of the bench
top tester and test area will contribute to errors. The heating or cooling of exposed product in the
bench top tester and test area will change its moisture.
Let’s look at an example where an operator takes two moisture samples 20 seconds apart and puts
them into two separate containers.
If you take the first sample and put it into your bench top sensor, you will get a moisture reading.
Now if you put the same sample back into the tester again, you may get a slightly different reading.
This is called equipment error and it occurs because most bench top testers have a +/- 0.2% error
range. The DM510 moisture sensors have a similar error of +/- 0.2%, so it is possible for the two
sensors to read as much as a 0.4% difference and still both be acceptable.
If you now take the second moisture sample and put it into the bench top tester you will most likely
get another reading. This time the difference is because all the grain coming out of the dryer is not
exactly the same moisture. (For example, there are usually variations between different columns in
the dryer.) This is called sampling error. This is also evident when taking samples from inbound
trucks and it is the reason that you probe and sample from different parts of the truck, the idea
being to obtain a representative sample to get accurate overall average moisture.
Calibration Procedure
While equipment error cannot be eliminated much can be done to reduce sampling error. This is
why the DM510 comes with a sampling button for the outlet sensor. The concept is to have the
operator and the DM510 take a similar sample over the time the sample button flashes, a period of
about 30 seconds. This more representative sample provides a more accurate result.
We recommend the following procedure for calibrating the outlet sensor.
• Check the dryer to make sure grain is flowing past the sensor
• Push the sample button next to the DM510 outlet sensor (the sample button light will flash
for 30 seconds and then remain lit until the sample is entered or cancelled).
• While the light is flashing, take several small samples and put them into a container (DO
NOT take just one sample).
Page | 23
Dryer Master DM510
Operations Manual
• Mix up the sample. Test in the bench top tester. Take 3 or more tests and average them.
• Press ‘Calibrate’ on the DM510 panel to display the ‘Sensor selection’ menu. The sensor
with the sample waiting will show (Sample Waiting) adjacent to its menu entry. Use the
‘arrow’ keys to highlight the sensor, press the ‘Enter’ key to move to the data entry screen.
• The DM510 moisture sensor average for the 30-second test will be displayed.
• Type in your bench top meter result. Press the ‘Enter’ key to accept the value and return to
the ‘Main operation’ screen. Type in ‘0’ and ‘Enter’ or ‘Cancel’ to clear the calibration in
progress and return to the ‘Main operation’ screen.
The DM510 will automatically update its moisture calculation formula. If your bench top reading is
more than 1.0% away from the DM510 reading we recommend obtaining a second sample. If the
second sample gives a similar result you should enter the calibration and verify the product flow
past the sensor.
Note:
The DM510 Moisture sensors are factory calibrated to a standard. New
installations can routinely show significantly different readings between the
DM510 sensors and the bench top meter. A number of calibration or an
adjustment in the Supervisor Calibration menu will bring the sensors in line.
Calibration Frequency
Continue sampling at the frequency you are accustomed to. Calibrations can be performed any
time there is product in the moisture sensor. The DM510 will track the entries and make
adjustments as needed regardless of the operating mode. The Dryer Master support center can use
the information to track the performance of the sensor.
A good way of seeing if the DM510 is in calibration is to keep a list of calibration pairs. Two columns
in which the first column is the bench top reading and the second column is the DM510 reading
from the calibration data entry screen. The corresponding readings are beside each other and a
glance down the page will tell you if the Dryer Master is calibrated or if there is an outlier.
Setting Alarms
The DM510 comes with an alarm feature that can help you monitor your drying. You can set high
and low alarm limits for inlet moisture, outlet moisture, drying air temperature, and discharge rate,
inlet and outlet product temperature.
Note:
Alarm settings are provided for safety and operator convenience. Alarms can be
made ineffective; however the hazard of making these changes must be weighed
against the safety of operators and equipment.
Page | 24
Dryer Master DM510
Operations Manual
For each alarm limit there are two stages of alarm. The first stage is a warning alarm and the second
stage is a critical alarm. The warning alarm tells you there may be a situation for you to keep an eye
on. In many instances the DM510 will have made changes attempting to correct the situation.
Important:
The DM510 Dryer Master does not try to correct for all situations capable of
activating an alarm. Some Dryer Master alarms are for drying environment
information only. Operator intervention is often required.
If the DM510 cannot correct the situation, a critical alarm will be reached. This will return the
DM510 to Manual or Local mode either immediately or after some time. The action is dependent on
the nature of the situation.
Note:
It is very important the critical alarms be set in such a way as to allow a
reasonable drying environment without impeding the automatic actions of the
Dryer Master
Page | 25
Dryer Master DM510
Operations Manual
Description of Alarm Limits operation
An example can show this relationship.
Figure 9 - Alarm Limit Operation
Let’s assume that your moisture target is 14.5%, and that you want to be notified if the moisture
goes above 15.5%, and if the moisture reaches 16%, you want the DM510 to stop controlling and
return to Manual mode. For this example you would set your high outlet moisture warning alarm at
15.5% and your high outlet moisture critical alarm at 16.0%.
The one exception to how alarms are processed is the discharge rate alarm. For the discharge rate,
the alarms displayed in the alarm area are the warning alarms only. The critical alarm limits are
displayed and set in the supervisor setup. These alarms will limit the minimum and maximum
speeds the DM510 can run your dryer discharge either in automatic or in manual. You should set
these limits based on your experience with the dryer, the limits of your grain delivery system and
the constraints of your take away system. Remember the DM510 will not and cannot set a discharge
rate outside the limits you set in either manual or automatic.
For a complete listing of alarm limits refer to the step-by-step key instructions section.

Changing Products
The DM510 is set to dry eight (8) different products and is typically configured to dry Corn, Beans,
Wheat, Canola/Rapeseed or other, Corn Hot or Other, Beans or Other, Sunflower or Other, and Rice
or Other. The “or other” designation suggests that the product selection may be used for the named
product or any product. For each product a unique list of information and parameters is used, this
includes calibration of the moisture sensors for that product. It is therefore important that you dry
using the correct product setting.
The product name as well as the graphical representation (icon) of the currently selected product is
located at the bottom right corner of the main operations screen. To select/change the product
press the ‘Product’ key. The ‘Select Product’ menu will display, press the ‘arrow’ keys to highlight the
product, press the ‘Enter’ key or press the ‘number’ key adjacent to the selection to accept the choice
and return to the ‘Main operations’ screen.
What to expect when the DM510 is turned
on
The start-up sequence of the DM510 takes 1 to 2 minutes. At this time the DM510 CPU tests various
components and loads the DM510 Dryer Master system software. The alarm may sound
momentarily, the alarm and mode Status lights will sequence. The main screen will blank, followed
by the appearance Dantec logo, then possibly a continuous alarm and the Main operations screen.
With the dryer not running a number of alarms may occur, these may display a message on the
‘Main Operations Screen’, sound the alarm and possibly illuminate alarm status lights. The alarm
sound and message can be cleared with the press of the ‘Cancel’ key.
The DM510 stores the current operation information, makes Operation Backups on a daily basis and
System Backups on a weekly basis. This ensures the DM510 system is able to restart full control
within one dryer load after a shutdown or power failure.
Because the DM510 Dryer Master is a computer system, for added security, it requires a computer
UPS (Uninterruptible Power Supply) to bridge momentary power outages.
Note:
The DM510 Dryer Master should remain powered for the duration of the dying
season. Turning off the DM510 Dryer Master will cause interruptions in system
backups that take place at midnight every day.

The First Week of Drying
The Dryer Master Support center can assist you by fine-tuning your new DM510 Dryer Master during
the first week of drying, through the following three stages.
Calibrating the sensors.
During the first 24 hours of drying we recommend that you take a minimum of 10 samples and
input the results into the DM510. The DM510 should NOT be operated in automatic at this time.
Follow the calibration procedure previously described for best results. This will help ensure that the
DM510 moisture readings are in line with your Bench Top tester readings and it will also familiarize
you with entering calibrations. The objective is to make you comfortable with the moisture readings
provided by the DM510.
During this time you should become comfortable with the DM510 operation by setting and changing
the discharge rate, in ‘Manual’ mode, using the DM510 keypad.
Verifying the Throughput
The DM510 is collecting operating and performance data from the dryer while operating in ‘Manual’
mode; after 24 hours there is usually sufficient data for the Dryer Master to recommend a discharge
rate: when the Dryer Master recommended rate is similar to that being run. The system is ready to
be put into automatic mode. It will also be of benefit if the throughput of the Dryer is verified by
running product into a holding bin for a period of time. This will permit the verification of the dryer
manufactures throughput specification. The throughput is the volume of grain that goes through
your dryer, in one hour, at a specific rate. The correct holding volumes and throughput are of
paramount importance for good Automatic operation.
Drying in Automatic
When the Dryer volumes and throughput have been reviewed and confirmed, after the initial 24
hours of operation and the information matches the dryer specifications and installed information,
and you are comfortable with the DM510 moisture readings, it is acceptable to use ‘Automatic’
mode.
Periodically during the drying season the Dryer Master Support Centre may contact you to ensure
your DM510 is operating correctly, and to answer any questions you may have. If you have
questions or concerns, please do not hesitate to contact the Support Centre at 519 746-0223 or 888318-0009 (Toll free in North America)

A Typical Daily Routine
The following steps should be included in your routine when using the DM510:
1. Before dryer start-up, check the outlet moisture sensor to ensure it is clean and free of
debris. The sensor chute has no obstructions ahead of the sensor. The flow-metering
device if so equipped is operating. The flow restrictor if so equipped is installed.
2. Start your dryer as you have in the past from the dryer control panel. The DM510 panel will
indicate that you are in ‘Local’ mode.
3. At the DM510 panel, press the ‘Mode’ key, select ‘Request Manual’ mode. The ‘Manual Mode’
rate entry screen will appear. Press ‘Cancel’ to accept the displayed discharge rate and
return to the ‘Main Operations Screen’, or type in a new value followed by the ‘Enter’ key to
accept the new value and return to the ‘Main Operations Screen’.
4. While in manual mode the rate can be changed via the ‘Set-point’ key menu.
5. Automatic can be selected when the Ready Status light is illuminated, to select Automatic
press the ‘Mode’ key, select ‘Request Automatic’ mode. The ‘Automatic Mode’ moisture setpoint selection screen appears. Press ‘Cancel’ to accept the displayed moisture set-point and
return to the ‘Main operations screen’, or type a new value followed by the ‘Enter’ key to
accept the new value and return to the ‘Main Operations Screen’.
6. While in automatic mode the moisture set-point can be changed via the ‘Set-point’ key menu.
7. The DM510 will now automatically adjust the dryer discharge rate to achieve the displayed
product target moisture.
8. Periodically check the moisture sensors to ensure they are clean and there is good product
flow.
9. While operating the dryer, calibrate the moisture sensors as required.
10. When you turn off the dryer, the DM510 will automatically revert to ‘Local’ mode after some
period of time. If this is not occurring the DM510 does not sense the Dryer as being OFF.
Verify and correct the DM510 alarm and limit settings.

Moisture sensor calibration involves a number of steps. For the outlet sensor the sample button at
the sensor is pressed to start the sample procedure. The button will flash for the next 30 seconds
while a manual sample is gathered. The gathered sample is tested on a Bench Top manual tester
for entry into the DM510.
The inlet calibration is not as critical and it is nearly impossible to gather a sample at the location of
the inlet sensor. Inlet calibration involves estimating the moisture at the sensor. The inlet sample is
gathered at ground level prior to elevating into the dryer. The calibration sequence is started from
the DM510 calibrate menu after sufficient time has passed for the product to reach the sensor.

Enter the complete reading you obtained
manually with the decimal point (for example if the reading was 23.2 % it must be entered as 23, the
decimal point, and 2). The reading will appear in the highlighted area. It is important that you verify
the reading before pressing the ‘Enter’ key to accept the reading.
In the event that the decimal is missed and the reading is entered as 232 the DM510 will record the
value but will not affect the calibration upon returning to the ‘Main Operations Screen’. The
incorrect entry will effectively be the same as canceling the calibration.

The alarms are divided into two categories, warning alarms and critical alarms. All alarm limits are
changeable by the operator. Warning alarms are provided to warn the operator that something is
exhibiting peculiar behavior and may require corrective action. Critical alarms are set to announce
that corrective action must be taken and in some cases will disable Automatic mode if no corrective
action is taken. There are also control limits set in the supervisor and installer setup menus that
may affect the setting of the alarm limits.
Note:
It is important to set alarms and limits to inform and contain operation within
the operating parameters of the dryer and facility. The DM510 default settings
may not be safe settings for your application.
Alarms are announced 3 ways, the DM510 alarm beeper will sound, a message will display on the
‘Main Operations Screen’, and for some conditions the alarm light will illuminate.
To clear the alarms press any key. Both the DM510 alarm beeper and the message will clear. The
alarm light will remain illuminated until conditions return to normal. In the event the DM510 is not
on ‘Main Operations Display’ while an alarm is occurring complete the task at hand and return to the
‘Main operation Screen’ to view the alarm message and cancel the alarm by pressing any key.

Max Discharge rate in Auto
This is the maximum discharge or unload rate that can be set by the
DM510 Dryer Master. Set this value to a reasonable maximum that will
not compromise safe Dryer operation. When setting this value ensure the
conveying system is able to manage the volume of product.
Min Discharge rate in Auto
This is the minimum discharge or unload rate that can be set by the
DM510 Dryer Master. Set this value to a reasonable minimum that will
not compromise safe Dryer operation.
Discharge Off Rate
The DM510 Dryer Master uses this value along with drying temperature to
determine the dryer state. Set this value to slightly less than the
‘Minimum Discharge rate in Auto’ value. Control will be severely
compromised if this value is set so that the DM510 does not obtain an
OFF indication.
Burner Off Temperature
The DM510 Dryer Master uses this value along with discharge or unload
rate to determine the dryer state. Set this to a value greater than the
maximum expected ambient temperature but less than the minimum
drying temperature. Control will be severely compromised if this value is
set so that the DM510 does not obtain an OFF indication.
Auto Fast Start
In normal operation the DM510 Dryer Master determines when it is ready
for Automatic operation. This process can take from a few minutes to a
dryer load or more. The Auto Fast Start feature bypasses the DM510
feature that determines stable operation. With Auto fast start the DM510
Dryer Master can be placed into Automatic before the ‘Ready light’ is
illuminated. A warning message with instructions will be displayed when
selecting Automatic before the ‘Ready light’ is illuminated.

(offset)
The displayed value is a bias or offset applied to the combined
temperature and dielectric signals returned from the DM510
moisture sensor. Adjusting this value has a direct impact on the
displayed moisture value on the ‘Main Operations Screen’ The
DM510 calibration procedure also has an impact on this and other
values when calibrations are performed.
Before adjusting this value cancel any calibration in progress and
note the displayed bias value.
Example Inlet calibration adjustment.
DM510 Inlet reading
= 26.5%
Manual test
= 21%
The DM510 needs to read 5.5% lower.
26.5 - 21 = 5.5
Reduce the ‘Inlet calibration bias (offset)’ value by 5.5
8 – 5.5 = 3.5
Outlet adjustments are similarly made. To increase the displayed
moisture reading the displayed bias value will need to be
increased by the required amount. To decrease the displayed
moisture reading the displayed bias value will need to be
decreased by the required amount. It should be noted that the
bias value could be a negative value.

To calculate this value requires 3 items.
1) Product volume
2) Time

= minutes
3) Discharge rate
= DM510 rate
For example
If the dryer discharges 4500 Bushels in 1 hr 37minutes at a
discharge rate of 80% then the conversion factor is 34.7925.
1)
2)
3)
4)
1 hr 37 minutes = 60 + 37 = 97 minutes
Bushels/minutes = 4500 / 97 = 46.39
Bushels/hour = 46.39 * 60 = 2783.4
Bushels/hour / rate = 2783.4 / 80 = 34.7925
The value to be entered as the ‘Rate to Bushels/Hr Conversion’
factor is 34.7925.
The Accuracy of the value depends on the accuracy of the
measurements. This is in the 'Approximate Production' output in

Operations Manual
Appendix 1: Hints for Better Drying
Start-up and Shutdown
There are costs associated with start-up and shutdown of the drying operation. Typically, a dryer
that is shut down will still be filled with grain. During the shutdown period, residual heat and normal
convection of ambient air will continue to dry the grain. However, the moisture changes will not be
the same throughout the dryer.
As a result, at start-up, there is a tendency to produce over-dried product before the drying process
can be stabilized. It is recommended, therefore, that dryer shutdowns and start-ups be kept to a
minimum. One method to accomplish this is to accumulate enough grain before start-up to allow
for a longer drying run. An alternative is to prolong the drying run by lowering the burner
temperature.
In the event that a shutdown is necessary, develop procedures for shutdown and start-up that
minimize the effects on the grain remaining in the dryer. Keep the following in mind:
After you turn the heat off, don’t leave the fans running for longer than necessary. Running the fans
dries the grain even without the burners running.
If your dryer takes a long time to cool down, leave the discharge system running for some of the
cool down time.
When starting the dryer select a start-up discharge speed similar to that used when the dryer was
shut down. Consider the drying conditions are they similar?
When you start-up the dryer, remember the grain in the dryer may be over dried. The idea is to pick
a good speed for the grain coming into the dryer.
Drying Air Temperature (Air Plenum Temperature) (APT)
Maintain a constant drying air temperature. If an adjustment is required, make the adjustment in
one step. Then wait one dryer load to allow the dryer to stabilize. Avoid making repeated
temperature adjustments. The DM510 will observe and adjust for drying air temperature (APT)
changes but only after the results have begun leaving the dryer.
Tempering
When grain with varying moisture levels is held in a tank for a period of time (typically 12 hours), the
moisture distribution will equilibrate. This is referred to as tempering.
Large dryers cannot respond quickly to large, abrupt changes in the moisture content of the
incoming grain. Although the DM510 will significantly reduce these kinds of effects, the response
limitation of the dryer will still result in undesirable variations in output moisture levels.
If there is an opportunity to temper the grain before feeding it into the dryer, abrupt changes will be
less likely.
The tempering process may also apply after you dry. That is, a storage period will tend to further
remove some of unevenness of the moisture content, before shipping.
If tempering tanks are not available, you can still improve performance by avoiding receiving wet
grain into the same bin that you are currently using for drying.
Page | 71
Dryer Master DM510
Operations Manual
Cleaning
When foreign material and fines are present in significant quantities in the grain entering the dryer,
they can result in inaccurate dryer response and higher drying costs.
Fines can be present in varying quantities and will affect the accuracy of grain moisture
measurements. Since the fines are drier than the grain, they create an inaccurate impression of the
actual moisture level in the grain. This can result in a higher moisture content being noted in the
grain when the fines are removed.
If fines and foreign material are present in significant quantities, the grain should be cleaned
before
drying rather than after drying. Cleaning before drying will improve drying efficiency and, reduce
the probability of blocking the dryer screens. Cleaning before drying will also reduce the chance of
plugging the moisture sensors, reduce the risk of fire, and provide more accurate readings from the
moisture sensors.
Bench Top Moisture Meter Calibration
The bench top moisture meter is the standard that the DM510 sensors are calibrated against. If the
manual reading from your bench top moisture meter is not accurate, then the DM510 moisture
reading will not be accurate. Accuracy of the manual reading depends on maintenance and
measuring procedures. Most meter manufacturers specify that the meter should be checked
annually by a qualified service person. These checks will ensure that the meter is accurate. Also,
ensure the DM510 sensors are clean and grain is flowing properly into the sensor.
Sampling Techniques







Follow these practices to ensure a good sample is obtained for sensor calibration:
Ensure the sample used in the manual reading is a good representative sample of the grain
exiting or entering the dryer. Collect the sample at the same time the DM510 is sampling.
(Review the calibration procedure in the ‘Calibrating the DM510 Sensors’ section of this
manual)
Follow the bench top moisture meter manufacturer’s procedures for measuring moisture
content.
Ensure the temperature of the moisture meter cell is close to the temperature of the grain
being measured.
Use care in applying the procedures accurately (weighing and pouring the sample, and
reading the temperature of the grain).
Test the product immediately. Do not leave it in an unsealed container waiting to be tested.
If the temperature of the product is significantly different then the temperature of the tester
seal the product in an air tight container and wait for the temperature to equilibrate before
testing the product.
Airflow
The dryer design assumes that airflow for a given fan speed will be consistent throughout the dryer.
Blocked screens as a result of rust and fines can affect airflow. This in turn has an impact on dryer
efficiency and the DM510 performance.
Page | 72
Dryer Master DM510
Operations Manual
Discharge System
The discharge system must be checked and maintained to operate as designed. This will ensure
that the product is removed in a uniform manner from the dryer. It can be beneficial to test the
dryer throughput at the start of the season. Any change in equipment or calibration of the
discharge system equipment will likely require an adjustment to the DM510 Dryer Master volume
and throughput setup.
Burner
Burners cannot meet performance specification if neither the burner controls nor the burners are
regularly serviced. An unserviceable thermostat or poorly adjusted burner control system will not
keep the heat at a constant temperature. A dirty burner or a burner control problem may prevent
the burner from reaching its maximum designed output, or prevent it from maintaining a consistent
gas pressure.
Product Quality
Varying product quality can have an affect on Dryer and DM510 performance. Light crops tend to
dry more easily than heavy crops. This can result in a situation where columns in a dryer have over
dried product while others are wet. The DM510 can only attempt to average the product exiting the
dryer. This behavior can result in poor DM510 moisture sensor to bench top meter calibration
agreement and generally poor moisture control.

Appendix 2: Troubleshooting - Control
The DM won’t go into Automatic
First make sure that the green Ready light is lit. If the light is not lit then the DM does not yet have
enough accurate information to take over control. If you have been running for more than two dryer
loads and the Ready light has still not come on call the Dryer Master Support Center.
Trying to go into Automatic when the system is not READY will provide the operator with a message
to indicate the reason why the system will not go into Automatic
Why won’t the DM go Ready?
There are a couple of possible reasons. The first thing to do is to make sure that there are no alarm
lights lit (the red LEDs on the top left of the panel). The DM can not go Ready if any critical alarm is
active.
Next to go Ready the DM has to meet a few conditions. First the current outlet moisture has to be
within 2 % of the moisture setpoint (target) and second the predicted outlet moisture (by the Dryer
Master model) must be within 2% of the actual moisture, [You can check the predicted exit moisture
by pressing Support then Diagnostics the Up Arrow. The bottom number in the PEM column is the
predicted exit moisture] and of course no alarms can be on.
Note even if the DM Ready light goes on you should always check that the suggested rate on the
screen is reasonable before going into Automatic.
Why does the DM speed up / slow down when I go to auto ?
Often when you first start up for the day the first grain that comes out of the dryer can be over dried
after having sat in ther dryer for a while. So if you are running below target for the first hour and
then go into automatic the DM is going to want to run above target for a while to have some under
dried grain to mix with the over dried grain and give you your overall target moisture once
everything has tempered in the bin. If you don't want this to happen at start up then start with a
lower target moisture and then move it up gradually to where you want it to be. In this way the DM
will not try to compensate as much for your over dried grain.
In the same way, if you have been running above target for a while and then switch to Automatic the
DM will want to slow down to come below target to give you an average moisture that is close to
target.
The DM uses rate manipulation to reduce the variation at the outlet to get more grain dried closer to
target. These rate chnages are more dramatic when the difference between the inlet and outlet
moistures is small.

likely the DM has not yet been set up for this product.
The moisture is above target and yet the DM wants to speed up (or the
reverse).
By the time the grain is coming out of the dryer it is too late to make a speed adjustment to change
this moisture. Instead the DM is focused on what is in the dryer, what is coming into the dryer, and
any change in drying conditions. For example, if the exit moisture is above target but the inlet
moisture is falling the DM may want to speed up the dryer to make sure this incoming dry grain is
not over dried by too much.
All the grain is not coming out at the moisture setpoint (target).
The DM can only help you maximize the performance of your dryer. It helps you run at the best
discharge rate for the mix of grain in the dryer, but it can not break the laws of physics. The DM will
try to dry your grain to your average moisture set point. Some grain will be above and some below
the set point, but on average the total average should be very close to the set point over a few dryer
loads.

Check to see that the following settings are correctly implemeted: “Dryer discharge off rate” and
“Burner off temperature”. If these re not correct the DM may not have known the dryer was off and
kept calculating numbers for its model. This means the model will need a dryer load or two to
correct its information.

Press the Settings key
Press “1” for Supervisor set-up
Enter the password “123”
Press “1” for Control Limits.
Check the “Dryer discharge off rate”. It should never be “0”. It should be above zero, but
below where you would run the dryer while drying. So for example if you usually run at a
rate of 20-60, set the value at ”5”
Check the Burner off temperature. This should be set about 30F below the low temperature
you would dry at. So if you normally dry at 180F, set it at 150F. It must also always be above
ambient temperature and well above the plenum temperature after the cool down cycle.
Appendix 3: Troubleshooting - Moisture Sensors
The inlet sensor is reading 1% too high. Should I calibrate?
No. As long as the inlet reading is within 1-2% of actual that is fine. The DM is most concerned with
the change in the inlet moisture not the actual reading. If you calibrate quite frequently the DM will
think that these are real changes and react accordingly.
The outlet moisture keeps moving up and down. Why?
All kernels do not come out of the dryer at the same moisture. This is the normal variation that you
normally don't see if you only take hourly samples. By continuously looking at the real time
moistures as they move up and down the DM is able to have more accurate averages with which to
make control decisions. You may also see that moisture variations tend to me more pronounced on
round tower dryers as the different columns may dry and unload at different rates.
Page | 76
Dryer Master DM510
Operations Manual
When I start up for the day the calibration is off?
It is usually best to wait an hour or so after you start up to begin calibrating the sensors. This is
because the first grain coming out of the dryer (and that has been sitting in the dryer for a few
hours) has a different moisture gradient (the difference in moisture between the inner part of the
kernel and the moisture at the outer part) in the kernel than does grain that has just recently gone
through the hot zone. You should avaoid calibrating the outlet moisture sensor anytime the
moisture is more than 1% away from target.
The moisture sensor reads empty but there is product in the sensor
It can be that the product is dry enough that it is at the low end of that partuicular sensor model
(below 10-12%). If it reads fine at higher moistures that is the issue. Otherwise there may be an issue
with the sensor – so contact the Dryer Master Support Center.
The moisture sensor is reading frozen
This typically happens when the temperature sensor on the moisture sensor fails (although it can
also happen is the outside temperature is below -30). Contact the Dryer Master Support Center.
The inlet sensor is reading 45%
This can be due to surface moisture on the sensor and this can happen when you first start up in the
morning and there has been condensation on the sensor. This should resolve itself once the grain
flowing past the sensor wipes away the moisture. This can happen during extended preheats.
A second possibility is that the inlet sensor has been installed where it is getting steam coming up
from the hot zone. In this case it may be necessary to reposition the sensor.
A third possibility is that there may be an issue with the sensor itself. If the issue does not resolve
itself contact the Dryer Master Support Center.
The moisture sensor won’t stay calibrated.
First make sure that you are taking your moisture samples in a consistent way over the 30 seconds
that the calibration button is flashing.
Second try separating your manual sample into three parts, testing each part, and then taking the
average of the three readings to enter into the DM.
Note that variations in the amount of FM and or severe changes in bushel/test weight can impact
calibration.
In addition, some models of dryers can have significant variation in moisture from column to
column.
If you still have this issue, contact the Dryer Master Support Center.
