Introduction
open during start up.
If the lint door/drawer is accidentally opened
while a program is running, the program will
stop and the display will indicate a diagnostic
message.
The program restarts once the door is closed
and start is pressed.
3. Depression Alarm
The program will not start when the pressure
alarm is active. The EDG uses the cabinet sail
switch to determine if the exhaust blower is
operational. The sail switch must be open for a
program to start, and then be pulled closed by
airflow for the program to continue. For this
reason, stops and starts too close together in
time may not work because of fan inertia. If a
program starts and sail switch remains open, an
alarm is generated and the buzzer sounds (see
chapter “Alarms”.
4.
Motor overload
If the motors overload(s) trip during program
execution, the program will stop, generating an
alarm with relevant diagnostic on the display
and the buzzer will sound.
5.
Coin box 1
In the coin box version, this signal indicates that
a type 1 coin has been deposited (whose value
is configured in the specific field). Not Used.
6.
Coin box 2
In the coin box version, this signal indicates that
a type 2 coin has been deposited (whose value
is configured in the specific field). Not Used.

programmed set point.
8.
RFU
Not used in the USA.
Keyboard
The keyboard is equipped with the following keys
0-9 : these keys have a different function
depending on the situation.
1.
If you are choosing a program to run,
each key corresponds to a program - pressing a
key will display the name of the associated
program if named (Sheets, Towels, etc.).
2.
If you are entering numerical values, each
key inputs the associated number.
1.
If you are entering a program name
(therefore an alphanumeric sequence), pressing
each key will result in the inputting of the
associated values (numbers or letters) in turn.
For example, if you want to enter “A”, press
button “0” twice, if you want to enter “Z”, push
button “7” five times.
After pressing button “7” five times, if you press it
once more another “7” will be generated. If you
press it for the eighth time, a “W” is generated
and so on, in rotation for all the other keys as
well.
“START” : starts the selected program
(both in case of single cycle or pre-set programs)
or restarts the program previously interrupted
(through STOP or by opening the door).
“STOP” : this key also carries out different
functions if pressed under different operating
conditions :
1.
During program execution, pressing this
button once suspends the program (with the
possibility of restarting it from where it left off),
while pressing it twice stops the program for good
;

2.
During programming, this button allows
to exit the currently programmed item and
returns to the program selection mode. All data
entered up to that point will be stored;
3.
Silences the buzzer.
SINGLE CYCLE : if pressed while the
dryer is waiting for a program to be selected,
allows to set a simplified program in which the
operator can choose both temperature and
program length. Please see Section 5.2 - Single
Cycle.
“UP” and “DOWN” : these keys are
used during the various configuration phases
for the following purposes :
1.
To select the type of currency during the
machine’s configuration phase (in case of coin
box operation) ;
2.
To select the program to modify during
the program modification phase ;
3.
To set YES/No values where
configuration require such a choice : for
example, when you’re setting up coin box
operation, press UP for YES and press DOWN
for NO ;
4.
When inputting a program name or
number, pressing DOWN alone will allow you
to erase the characters or the numbers
displayed at the far right.
“UP” and “1” : press these two keys
simultaneously while the dryer is waiting for
program selection to access the password
mode. In other words, the board waits for a
numeric password, and once this is changed it
will be possible to access the various machine
and program configuration phases.
ENTER : below is a list of what can
happen when this button is pressed with the
control unit operating under different modes:
1.
After selecting a program (without the
coin box), pressing this key will start the same
program. If this does not occur, it may be that
one of the conditions supplied by the inputs is
missing. In case of coin box operation, pressing
this button starts the machine only after
reaching the minimum starting credit required
for the selected program;
2.
After suspending program execution (by

Press ENTER : if the number is within
the allowed range the message “HEAT”
appears (requesting the drying temperature).
6.
Press ENTER : the number “00000”
appears (default temperature expressed in °F or
°C, depending on machine configuration).
7.
Use the numerical and DOWN keys, as
in points 3 and 4, to set the desired
temperature.
8.
Press ENTER to confirm the input

displayed.
opening the door or by pressing STOP once),
pressing this button will restart the program
exactly from where it left off ;
3.
Dduring programming phases, pressing
this button allows to switch from one parameter
to the next.
In particular, when the name of a parameter is
displayed, pressing this key displays - and allows
to modify - the actual value of the parameter in
question. Once you’ve seen (or changed) the
value, pressing ENTER again allows to move on
to the next parameter.
If this does not happen after pressing ENTER, it
means that the new value is outside the allowed
range. In this case, you can correct the value or
cancel the change by pressing STOP and halting
the programming.
Program selection and execution
To select a program, press one of the 10
numerical keys found on the keyboard.
1.
When you press one of these keys, the
name of the associated program will be displayed
(it will move across the screen since the max
length is 12 characters).
2.
At this point, pressing START allows to
start the program. The program name disappears
and the current temperature in the drum along
with the time remaining until the end of the
program (residual time) will be displayed moving
across the screen.
Single cycle
When you press the SINGLE CYCLE key, you
will be asked to input the length of the drying
program and the desired temperature.

Programming
Programming includes machine configuration (1 or 2 motors, coin box or no coin box), operating
ranges (the desired settings - language, times), and lastly the definition of the behavior of each
single drying cycle.
All programming phases start by entering the correct password, after which the operator proceeds
to enter the desired parameters.
All programming phases can be stopped at any time by pressing STOP. All parameters entered up
to that point will be stored, except for the current one.
All temperature range values listed in the following tables are expressed in °C. In case the board is
configured for operation in °F, all values will be automatically converted.

Details
List of phases carried out during
program execution
During the cooling down phase the display
shows the message “COOL DOWN”.
This phase differs from the drying phase mainly
because heat adjustment now ends. Cool down
is completed once the relevant temperature set
in low level programming is reached, or when
the relevant time expires (also set in low level
programming), depending on which of the two
conditions occurs first.
When this phase ends, the flow of compressed air
is cut off and the gas control unit reset signal is
turned off. At this point the fan turns on and the
actual drying phase begins. Up until now the
display shows the name of the selected program.
The anti-crease phase is preceded by a 2minute pause interval, during which the
machine remains inactive.
When the user has selected the desired program,
START must be pressed to begin the program. In
order for this to occur, the heat intake fan must
not be running (the EDG must detect the sail
switch transitioning from open to closed).
Once the program starts, a set of operations is
carried out periodically, regardless of the program
phase currently under way. These operations are At the end of the cool down phase the dryer
as follows :
stops, and the “Dryer Busy” signal turns off.

program.
Heat adjustment is carried out during this phase
so that the temperature inside the basket may be
kept at the set value, with a 3 °C hysteresis.
The display showing information about the
program under way, in other words actual
temperature and residual time, is updated every
6 seconds.
In addition, basket movement is started. This, if
the machine is equipped with reversing,
determines an alternate basket movement
according to the times set in the program. In case
the machine is not equipped with reversing, the
basket is connected to the fan motor which gives
it its motion.
The machine moves on to the next phase,
cooling down, when the residual time expires.
10
At the end of this pause the anti-crease cycle
begins.
This cycle can last for a maximum of 99
minutes, and it stops every time the door is
opened. During this phase the basket moves
periodically (with alternate motion if reversal is
enabled). In addition, the buzzer goes off every
time motion starts.
Once the anti-crease cycle is finished the
program is done.
Restart after a program interruption
Every time a program is interrupted (door
opened or STOP push-button pressed), the
subsequent restart (by pressing ENTER) no
longer begins from the starting phase but rather
from the drying one.
Details
Restart after a power failure
In case a power failure occurs while a program is
running, the following information will be stored
in memory : number of the program under way,
the residual time, the phase under way and any
other data required to restore the operating
conditions in force right before the power failure.
When the power supply is restored, the display
indicates the program interrupted, and the user
can press ENTER to start it or STOP to stop it for
good.
Specific behavior of the single cycle
The execution of a single cycle is rather simple
compared to that of a complete program. In case
of single cycle, a group of settings is carried out
using standard values (not set by the user),
namely:
The basket rotation time is set for 20 seconds
Pause time during basket rotation is also 20
seconds
The cooling down phase lasts 5 minutes or
until a temperature of 35°C is reached
At the end of the program the buzzer goes off
for 2 seconds
The anti-crease cycle is not carried out at the
end of the program
