MERLIN A15
15KG BATCH ROASTER
IMPORTANT SAFETY INSTRUCTIONS
The roaster MUST be placed on a flat level surface capable of supporting its weight.
Keep area around roaster clean and dry and clear of obstructions as required by local
safety regulations.
Do not REMOVE safety covers or DEFEAT safety interlocks at any time.
There are many HOT surfaces when the roaster is in operation, use caution around the
roaster at all times.
NEVER reach inside the roaster’s main hopper while it is hot, excessive heat could cause
severe injury.
NEVER reach inside cooler tray when mixer is running or injury may result. NEVER
reach inside the mixer when the power is on as the mixer can start automatically at any time.
All cooler ducting and the cooler fan can be EXTREMLY HOT. Allow to cool before
disassembly for cleaning.
The sample tryer has sharp edges and may be quite hot, hold by wooden handle only.
Be very careful when wearing loose clothing or having long, unbound (loose) hair around
the roaster. Hair and clothes can become caught in moving equipment and cause severe
injury.
Turn off power and close all utility valves when the roaster is not in use.

START-UP
Empty the chaff collector drum. Reinstall the chaff drum and be sure that the locking
clamps are securely latched.
Be sure all cooler ducting is installed with gaskets and clamps are latched tight.
Check to see that the cooling hopper is empty and close the cooler discharge gate.
Close the roaster door.
Open the utility valves for air, water and gas.
Turn roaster “POWER-ON/OFF” switch to the ON position, momentarily. The power
will come on and the switch will spring back to center. The display screen will boot.
Make the necessary adjustments required to satisfy any fault conditions that may be
indicated on the startup screen once it boots.
WARM-UP
Push the “BURNER” button in the lower left hand corner of the display screen. The
frame of the button will switch to green (see Picture 002).The roaster will automatically purge the
system and then the burner will ignite. When ignition starts, the center of the burner button
will turn green and the green “burner on” light will light on the front of the control console
(see Picture 003).
The roaster will begin to warm-up.
The roaster will warm up to the preset “Idle Mode” (see Picture 004) high temp value, usually
around 450 degrees F., and the burner will be turned off by the system. At this time, the
roaster will indicate that it is in Idle Mode. By turning the burner on and off between two
preset temperatures, the roaster temp can be maintained within a narrow band. If the burner
is left on at low fire when the roaster is empty, the temp would continue to climb and the
roaster would get too hot. By cycling the burner, the temp is maintained at an appropriate
level. The burner will reignite at the Idle Mode low temp setting (based on return air temp).
The process takes from 20 to 30 minutes depending on the temp in the room and the target
values chosen by the operator on the setup page for Idle Mode High and Low Set point
values. See section on the “Setup” page screen.
A roast may be started at any time but many roast masters wait for the Idle Mode to
“porpoise” a couple of times to fully preheat the roaster so the first roast won't be too much
longer than subsequent roasts. This porpoise cycle takes about 10 minutes.
“LOAD GREEN” button is needed to activate the automatic modes, Recipe Mode and
Profile Mode. Once the beans are loaded, push this button to send the signal that the beans
are ready to automatically drop when the roaster reaches “Drop Temperature”. This button is
not used in Manual Mode.
Select the batch size that you wish to roast. To select the batch size, touch the yellow
button located under the burner percentage reading at the top right of the screen (see Picture 004).

Select the name of the product you are about to roast from the list of product names you
entered under the “SELECT PRODUCT” button of the “ROAST LOG COMMENTS” tab. It
will now appear on the main “MANUAL ROAST” screen (see Picture 006, 007, 008).
At this time, you may also select a “BASELINE” if you want to monitor the roast
progress relative to one from memory. You will be able to view the actual (current) bean
temp. as it progresses, on top of the graph of the historical baseline on the “PLOT SCREEN”
(see Picture 010) accessed by a tab on the main screen. You can roast by manually adjusting the
burner from this screen to keep the roast on track. The red line on the plot represents the
actual process value (bean temperature) and the white LINE is the historical graph of a roast
from memory. While in this screen you may use the “TREND” tab to view a larger version
of the normal trend display with most buttons minimized and some missing to make room.
Use “PREVIOUS” to return to the normal trend screen.
To select a baseline from memory touch the purple “RECIPE / PROFILE” button on the
main “MANUAL ROAST” screen. Touch the red “BASELINE PLOT” button top center on
the screen and it will turn green. Use the “LOAD PROGRAM FROM MEMORY” to select
the baseline you want to use and confirm with a “YES”. The baseline will now be available
from the “PLOT” tab on the main “MANUAL ROAST” screen (see Picture 009).
The endpoint temperature must be set or changed each time a new value is desired.
Touch the “ENDPOINT” digital indicator (see Picture 006) grouped with the other digital
temperature indicators at the top of the screen to set the desired endpoint for the new batch.
The endpoint you set here will be used to signal the end of roast approach both visually and
audibly.
If in “IDLE” mode, and the burner is off, it’s usually best to start the burner, so the
temperature will be rising in the roaster, then drop the beans at the desired drop temperature
by pushing the “DROP GREEN” button which will turn from red to green while the beans
are dropping. If the roaster is already above your desired drop temperature, open the roaster
door till the temperature falls 10 degrees or so below the desired drop temperature, then close
it and drop the beans at the desired temperature while it is rising.
You may adjust the burner as soon as the drop green gate is closed, as evidenced by the
green “DROP GREEN” button turning back to red. A timer will show on the button (see Picture
011), counting down the seconds that Green Hopper will be open which varies according to
batch size.
You may adjust the Circulation Fan speed, using “Slide” (see Picture 011) adjuster on the left
side of the touch screen, as soon as the drop green gate is closed. This function allows you to
control the movement of the beans.

MANUAL MODE: DURING THE ROAST
During the roast, you may jump between the “TREND DISPLAY”, “ROAST LOG
COMMENTS”, and the “PLOT” tabs (see Picture 012, 013, 014 and 015). You may also enter
“SETUP” and make changes to some of the basic values and parameters of the roaster.
On the “ROAST LOG COMMENTS” screen, you may attach notes from the on screen
keyboard that pops up when you touch the comment bar (see Picture 013). You may also type
them in from a physical keyboard on any PC on your LAN after you create a clone of your
roaster screen. Open a browser on your networked PC and type in “HTTP://” then your
roasters I.P. address, then “:5800” and hit enter. Your roasters I.P. Is most likely
192.168.1.200 but you can check on the information tab of the “SETUP” screen if that
doesn't work. You may also try another browser. They don't all support this but IE and
Firefox usually work. A Tight VNC password dialog box will open and you then enter one
of your two passwords. One is for viewing only and one is for interacting. You will need to
interact to enter your notes but be very careful, the screen is live and if you click on
something, it is just like touching it while standing at the roaster. Be careful with this!! (but
don't be afraid of it)
You may start the “TIME SINCE CRACK” timer manually (see Picture 013 and 015), and its
value will be recorded with the other roast data e-mailed at the end of the roast. Touch the
digital display of the timer to activate it.
20 degrees F (9 deg C) before the endpoint is reached the amber flasher on the front of
the consolet will start flashing. As the endpoint approaches the flasher will flash faster. At
10 degrees F (4 deg C) prior to the endpoint, the horn will sound off one time for about a
second. The volume of the horn can be adjusted by rotating the bezel of the horn. At 5
degrees F (~2 deg C) below endpoint, the horn will sound off several times.

“Time Since Crack” is a timer you start when you detect 1st
or 2nd crack. This is only a timer; it does not detect “Crack”.

MANUAL MODE: ENDING THE ROAST
At the end of the roast the screen will flash “END OF ROAST” and the horn will sound till
the door is opened. The horn may be silenced with the “SILENCE HORN” button on the
screen. You may also disable the end of roast horn signal in setup.
MANUAL MODE: POST ROAST & IDLE MODE
“POST-ROAST” exists because there is residual smoke in the roaster after the coffee is
out of the roaster hopper. The burner remains on for 3 minutes after the end of the roast to
eliminate this smoke and this time is called “POST-ROAST”. After the 3 minutes, if you
don't start a roast, the roaster switches to “IDLE MODE”, and the burner is turned off and
then back on between the two temps set for “IDLE HI LIMIT TEMP” and “IDLE LOW
LIMIT TEMP” as established on the setup screen (see Picture 018 and 019). The roaster will remain
in “IDLE-MODE” till a roast is started, and the burner will cycle on and off between these
two temps which takes about 10 minutes per cycle depending on settings. This is often
referred to as “porpoising”.
The e-mail of the roast data is sent about 30 seconds after the end of the roast cycle, so be
sure all roast log notes are typed in prior to that time. The "ROAST LOG COMMENTS" tab
of the main screen accesses the roast log screen during the roast.
Agtron data collected after the roast may be sent in a separate e-mail after the roast data
e-mail has already been sent. The batch number is incremented automatically so it should
correspond to the batch it came from if it is done in the same order. However, you may not
keep Agtron data on every batch or for other reasons the batch number may get out of sync,
so it is adjustable on the Agtron screen (see Picture 020 and 021). The screen is accessible from the
“AGTRON & WEIGHTS” button of the “ROAST LOG COMMENTS” tab of the Main Run
Recipe screen.
Capturing data from a manual roast can create a recipe. To save the data from a manual
roast, click the purple “ROAST / PROFILE” button above the trend graph on the main screen
(see Picture 016). A new screen will appear allowing you to choose between “BURNER

RECIPE”, “BASELINE”, and “ROAST PROFILE MODES” (see Picture 017). Click the
“BURNER / RECIPE” button and it will turn green. Press the “CAPTURE LAST
MANUAL RUN FOR BASELINE PLOT” to capture the baseline, then “CAPTURE LAST
MANUAL RUN FOR BURNER RECIPE” button to capture the recipe. You must now
name the recipe and save it under the new name. To do this select “EDIT BURNER
RECIPE”. Create a name and save the recipe (see Picture 022 and 23).If you save it with the same
name as a previously saved recipe, you can overwrite the recipe in memory, thus modifying
it. A roast profile is created in much the same way but by activating the “ROAST
PROFILE” button instead of the “BURNER RECIPE” button.
A baseline can be created by capturing data from the last roast in much the same way a
recipe is saved; by activating the “BASELINE PLOT” button turning it green (see Picture 024) and
then touch “CAPTURE LAST MANUAL ROAST FOR BASELINE PLOT”. Now “EDIT
BASELINE PLOT”, give it a name, and then save it. In this way, a baseline is captured
independent of recipe functionality. If used in manual mode it is simply displayed (graphed)
in the plot screen and can be used as a template for controlling a manual roast using the
manual burner controls (see Picture 025). Need an accurate picture here and I need a BASELINE

MANUAL MODE: COOL DOWN
At the end of the day, or even on long breaks from roasting, when the roaster is in
“IDLE” or “POST ROAST” you can switch the roaster to “COOL DOWN” (see Picture 026). In
cool down, the burner is shut off along with all other motors except the circulating fan. The

circulating fan actually speeds up a little. Air is circulated and after a short time the purge
gate is opened so all the air is replaced with cool room air constantly.
If you touch “GO TO COOL DOWN” while in “POST ROAST”, you will see “COOL
DOWN REQUESTED”. We must let the “POST ROAST” cycle end before going to
“COOL DOWN” or we run the risk of allowing some smoke from the end of the last roast to
escape.
At the end of “POST ROAST”, the roaster will automatically switch to “COOL DOWN”
instead of “IDLE”.
The roaster takes 20 to 30 minutes to cool down. It is important so the heat does not
“seep” through to the bearings of the Circulation Fan Motor.
At the end of “COOL DOWN”, the roaster will turn off the circulation fan and return the
roaster to the initial startup screen. This happens when the return air temperature gets down
to 150 deg. F or 66 deg. C. At this point, you only need to turn off the power to the roaster
and close the utility valves for air, water and gas.
Picture 026
RECIPE MODE: SOME FACTS ABOUT RECIPES
To create or change a recipe (or profile) you must first Login. By default, the password is
3333. This may be changed at startup or later via the Internet or, by a field service engineer
from LORING SMART ROAST.
A recipe can only be “captured” from a batch that you roast in “MANUAL MODE”, but
can be created in other ways like creating from scratch using the “EDIT BURNER RECIPE”
screen, loading and editing an existing one, or importing one saved by someone else, or one
created in Excel and FTP'd into the screen via Ethernet.
A recipe is a record of the bean temperatures at which burner adjustments were made
during a roast, the new burner setting at each temperature, and the record (at 6 second
intervals) of the bean temperature graph generated during that roast. When the recipe is
“captured from last manual run”, the baseline from that roast is captured with it.
If a recipe is created by going to the “EDIT BURNER RECIPE” button from the
“RECIPE / PROFILE” (see Picture 027) tab and creating one from scratch, there will be no

baseline associated with it until the program is run and the baseline thus generated is saved
with the recipe using the same name.
You must have just run (or you must load) the recipe to which you want to add the
baseline before changing the name or saving the recipe.
Do not turn the "BASELINE PLOT" button green. Leave "BURNER RECIPE" green.
Touch "Capture last run for Baseline Plot"(see Picture 028), then touch "Edit Burner Recipe" and
on that screen make any changes you want to the recipe, including the name (or leave the
name) and hit enter (see Picture 029 and 30).
This will add the current baseline (from the last roast) to the recipe. Then you must save
it, with the same name, or a new name.
Touch "Save Recipe" and wait to see the name change (if any) indicated (see Picture 031).
A recipe may be created spontaneously by loading an existing one, modifying it, then
renaming it. It will retain the baseline of the recipe you modified until you run the recipe
(creating new current baseline data) and then saving that baseline to the recipe as described
above.
or going to the “EDIT BURNER RECIPE” button from the “RECIPE / PROFILE” tab

RECIPE MODE: STARTING A ROAST
Click the purple “ROAST / PROFILE” button above the trend screen on the main screen
(see Picture 032). A new screen will appear allowing you to choose between Burner Recipe,
Baseline, and Roast Profile modes.
To select a previously saved recipe, select the red “BURNER RECIPE” button which
turns it green. Once the central “LOAD FILE FROM MEMORY” button appears touch it
and select your chosen recipe from the drop down list, then confirm it with “YES” (see Picture
033, 034 and 035).
While you are here, you can select the name of the product you will be running with this
recipe. Do so and then push the green “RECIPE / PROFILE RUN” button (see Picture 036 and 037).
You will be switched to the “MAIN RECIPE RUN SCREEN” where the name of the
current recipe and the current product are listed (see Picture 038).
If your last roast was in recipe mode and you haven't changed modes, you will still be in
recipe mode. The same recipe will continue to run, batch after batch, till you load a different
one.
The endpoint temperature is best chosen right after returning to the “MAIN RECIPE
RUN SCREEN” after choosing the recipe and the product name. But it can be changed at
any time during the roast. Touch the “ENDPOINT” digital indicator grouped with the other
digital temperature indicators at the top of the screen to set the desired endpoint for the new
batch or change it on the recipe settings screen (see Picture 038).
A roast may be started at any time after the door is closed from the previous roast. It can
be started during “POST-ROAST” or you can wait and start it once the machine has entered
“IDLE MODE”.
To start a roast cycle press the green “PRESS TO START RECIPE RUN” button under
the digital Bean Temperature indicator.
The roaster will compare the recipes drop temperature to the current roaster temperature.
If the roaster is above it, a yellow flashing text block will ask you to open the roaster door till
the temperature drops below the required drop temperature. When it does, you can shut the
door and then a “WAITING TO DROP GREEN” message will appear. When the roaster
temperature reaches the (recipe specified) drop temperature, the green will drop

RECIPE MODE: DURING THE ROAST
The recipe software is now in control of the roast. Manual burner adjustments can be
made and will remain in affect till the recipe reaches the next control point. At that
temperature, it will make the scheduled burner adjustment.
During the roast, you may jump between the “TREND DISPLAY”, “RECIPE
SETTINGS”, “ROAST LOG COMMENTS” and the “PLOT” tabs (see Picture 039-046). You may
also enter “SETUP” and make changes to some of the basic values and parameters of the
roaster (see Picture 047).
The Magnehelic gage is mounted behind the control screen. It is a direct and physical
measure of the burner firing rate (see picture 048).
On the “ROAST LOG COMMENTS” screen, you may attach notes from the on screen
keyboard that pops up when you touch the comment bar. You may also type them in from a
physical keyboard on any PC on your LAN after you create a clone of your roaster screen.
Open a browser on your networked PC and type in “HTTP:/ ” then your roasters I.P.
address, then “ :5800 ” and hit enter. Your roasters I.P. Is most likely 192.168.1.200 but you
can check on the information tab of the “SETUP” screen if that doesn't work. You may also

recorded with the other roast data e-mailed at the end of the roast. Touch the digital display
of the timer to activate it. Many roast masters use this timer to keep track of how long the
roast proceeds after the start of the first crack.
You may switch to “MANUAL CONTROL” of the roast at any time but may not reenter
“BURNER RECIPE MODE” during that batch. You will have to complete the batch in
“MANUAL MODE”, the plot screen will not assist you, and the roast timer will stop.

RECIPE MODE: ENDING THE ROAST
The endpoint temperature is part of the recipe (see Picture 049). The Amber light on the front
of the consolet will flash @ 20 degrees F (9 deg C) before it has reached the endpoint
temperature (Picture 050). As the endpoint approaches the Amber flasher will flash faster. At 10
degrees F (4 deg C) prior to the endpoint, the horn will sound one time for about a second.
At 5 degrees F (~2 deg C) below endpoint, the horn will sound several times.
At the end of the roast, the screen will flash “END OF ROAST” and the horn will sound
until the door is opened (Picture 051). The horn may be silenced with the “SILENCE HORN”
button on the main screen (Picture 052). The volume of the horn can be adjusted by rotating the
bezel of the horn (Picture 053). You may also disable the end of roast horn signal in setup (see
Picture 054).
The e-mail of the roast data is sent about 30 seconds after the end of the roast cycle, so be
sure all roast log notes are typed in prior to that time. The "ROAST LOG COMMENTS" tab
of the Main Run Recipe screen accesses the roast log screen during the roast (Picture 043).
