1 Introduction
1.1 PROBA ripening system set up
The PROBA110 Ripening System is a solution for the automated ripening of bananas. The system measures and
independently controls the temperature and it can also control the relative humidity and gas concentration in the ripening
room as options.
Air refreshing of the bananas is also controlled by the system.
During a period of several days the system is capable of controlling one or more ripening rooms in such a way that perfectly
ripened fruit can be removed from the rooms at the end of the ripening cycle.
The PROBA Ripening System consists of the following main components:
* Control Computer for each ripening room (PROBA110).
* Central Computer.
* Network and Network Interface (PROBA120).
The ripening room is fully controlled by the control computer PROBA110. This steps through a ripening program
independently and can be controlled by the user via the front plate.
It is also possible to connect one or more of these control computers via a network to a central computer. All process
parameters of the connected control computers can be changed from the central computer. In this way up to 99 rooms can
be remotely controlled from the keyboard of the central computer.
In principle the central computer is always connected to the network and running the PROBA-software.
If the PC is also used for other purposes, the data logging will stop and information will be lost. In that case the ripening
processes will simply continue, since the control computers are able to finish their program, if necessary by manual control.
This also guarantees that in case of a computer breakdown, the ripening process continues.
It is possible to connect several computers at the same time to the network. Each PC has its own PROBA120 Network
Interface. There is also an option to connect other instruments to the network, such as MC785 thermostats. Please note that
all these instruments are capable of communication via the PROBA network.
1.2 Operation of the PROBA ripening system
The bananas in the ripening room are ripened by means of ripening programs. In the PROBA ripening system the length of
these programs and the temperatures are adjusted each day.
The ripener can make a choice from 20 different ripening programs for each PROBA110.
The temperature profile is setup by means of temperature setpoints, one for each day. During the execution of the program
the temperature is checked and controlled by the PROBA110 in such a way that the fruit is ripened according to user
settings.
The PROBA110 is also able to control the application of gas during the ripening program. The duration or the concentration
of the gasification are adjustable, depending on the presence of the optional gas concentration sensor. During this period the
PROBA110 will indicate that gas is present in the ripening room and the door of the ripening room can be blocked.
During the ripening process the bananas can be ventilated. The length and interval of the ventilation are adjustable. During
gassing periods the ventilation is blocked. The PROBA110 indicates when the room is being ventilated.
At the end of a ripening program the PROBA110 switches over to the so-called STANDBY mode. The temperature
regulation continues on the STANDBY setpoint which ensures that the ripened product remains in a controlled environment.
At any moment during the ripening program the temperature setpoint, which is used by the PROBA110 at that moment, can
be changed. The ripening program can also be changed into STANDBY mode or stopped anytime by the user.
A ripening program can be displayed schematically as follows:

VDH Products BV Document 063319 - version 3.12 Page: 6 of 78
During a number of days (the length of the program, in this case 4) a temperature setpoint is setup for each day. On a given
day, the PROBA110 regulates the temperature in the ripening room to be equal or close to that particular value. The length
of a ripening program can be varied from 1 to 9 days.
After setting up and starting a program the PROBA110 starts at day 1. In the example the temperature setpoint is now
17.5C, so the PROBA110 regulates the temperature to become 17.5C. At the end of each day (24 hours) the temperature
setpoint is changed into that of the next day of the program. After all days of the program are past, the PROBA110 goes to
the STANDBY mode. The STANDBY temperature is also adjusted in the ripening program. The STANDBY mode remains
active until the user stops the ripening program or starts a new one.
Finally a warming-up phase can take place before the ripening program starts. For convenience this precursion time is called
day 0. The length of precursion time is variable and temperature control during the precursion time is possible.
Optional gas, humidity, pressure or CO2 sensors can be connected to the PROBA110.
If a gas concentration sensor is used, gasification can be carried out on gas level. An alarm will follow if the programmed
level is not reached within a certain time. If the gas level is too high, the ventilation can be started automatically.
The relative humidity sensor measures the relative humidity in the room. Depending on the desired level the humidification
can be switched on automatically. When exceeding the minimum or maximum alarm levels an alarm will be generated.
Based on the pressure difference across a pallet the pressure fans can be switched on and off. Also an alarm will follow if the
pressure difference is too low.
With a CO2 sensor ventilation can be started when the level of CO2 exceeds the maximum set value.
1.3 Methods of temperature control
Up to nine temperature sensors can be connected to the PROBA110.
The PROBA110 can control the temperature in the ripening room by two ways. The first method is based on the average
pulp temperature in the ripening room. In the second method the air temperature is controlled in each section.
1.3.1 Temperature control based on the average pulp temperature
This method of control makes use of a maximum of nine, but mostly three, product sensors which are placed in
selected boxes of bananas (pulp temperature). These use product sensors type SM8500 which are connected via
coiled leads to the connection boxes.
The temperature is controlled on the average of the present and active product sensors. The cooling and heating
are driven simultaneously for the whole ripening room.
The product sensors are also used to signal warnings and alarms.
As an option, mostly two alarm sensors type SM8000/2m, can be connected. These sensors control the minimum
and maximum temperature of the airflow coming out of the evaporator. The evaporator can be temporarily switched
off if the alarm levels are exceeded.
In Appendix A (see page 43) a schematic drawing is given of this method of temperature control.
1.3.2 Temperature control based on air temperature
With this method of regulation the ripening room is divided into a maximum of three zones. The air temperature
within each zone is regulated separately. So the cooling and the heating are controlled per zone.
For each zone one control sensor is used, and is placed in the airflow from the product (or entering the evaporator).
These make use of air sensors type SM8300.
The control sensors are also used to signal warnings or alarms.
Next to the control sensors there are, as an option per zone sensors available for warning and alarm functions
(temperature too high or too low). These sensors are placed in the airflow entering the product.
In Appendix B (see page 44) a schematic drawing is given of this method of temperature control.

VDH Products BV Document 063319 - version 3.12 Page: 7 of 78
2The PROBA110
2.1 Control of the PROBA110
The control computer PROBA110 can be controlled fully via its front panel. If the PROBA110 is connected to a Personal
Computer there is also the possibility to control the PROBA110 from this Personal Computer. In both cases all process
parameters of the PROBA110 are adjustable.
In situations where there is no network system, the PROBA110 always operates 'Stand Alone', which means it is fully
independent and the control takes place via the front panel.
The PROBA110 has a number of control and display features:
* Key switch,
* Push buttons,
*two 4-Character displays,
* LED's,
* Buzzer.
The control can be distinguished in:
*Off / On / Program Enable (PE),
* Readout of the sensor values,
* Change of setpoint(s),
* Programming and starting of regulation,
* Programming of control parameters and alarms.
Functions of the LED's:
ALARM Lights in case of an error.
VENT Displays the status of the VENTILATION relay.
MOIST Displays the status of the MOIST relay.
GAS Displays the status of the GAS relay. During gassing this flashes if gas is present in the room
(gassing is taking place).
COOL (3) Displays the status of the COOL relays.
HEAT (3) Displays the status of the HEAT relays.
FAN (3) Displays the status of the FAN relays.
DAY row This row of lights displays the length of the ripening program. One of the LED's flashes to indicate
the current day.
SENS row This row of lights displays which sensors are active.
TEMP/VENT Indicates if the key can be used
HUM/GAS Indicates if the key can be used
STANDBY Lights when the PROBA110 is in the STANDBY mode.
PROG Lights when a ripening program has started and ripening of the fruits takes place. Flashes during
programming.
SENS/TIME Flashes when a temperature or time is being read with the SENS key.
In general, an illuminated LED means that a function is active.
Please note:
If one of the COOL LED's flash, it means that cooling is being called for, but disabled because there is a fault e.g. if an air
temperature alarm sensor switched off the cooling because the temperature is too low.
If one of the HEAT LED's flash, it means that heating is being called for, but disabled because there is a fault e.g. if an air
temperature alarm sensor switched off the heating because the temperature is too high or if the HEAT function is switched to
OFF.
If an LED for a fan flashes, it means that the fan is being called for but this is disabled because e.g. the fan delay is active.

VDH Products BV Document 063319 - version 3.12 Page: 8 of 78
2.1.1 Key switch
The key switch located at the top right of the front panel of the PROBA110, has three positions:
OFF
The PROBA110 is switched off. The displays and the LED's are off, there is
no regulation. The PROBA110 does not respond to keys pressed.
ON
The PROBA110 is switched on. The regulation is active provided a ripening
program is in progress. the average temperature of the control sensors is
displayed in the upper display, the present setpoint in the lower display. The
LED's show the status of the operation conditions of the PROBA110. The
values of the different sensors and control parameters can be shown in the
display.
PE (Programming Enabled)
The PROBA110 has the same function as with the key switch in the ON
position. However the user is now able to program the ripening programs,
start, stop or change them.
In the normal situation the key switch is in the ON position and the key is
removed. The temperature of the sensors can be shown in the display, but it
is not possible to change the settings (accidentally). A ripening program
cannot be started or stopped.
For manual adjustment of the PROBA110 it is necessary to rotate the key
switch into the PE position.
When the ripening room is not in use, the PROBA110 can be switched off by
rotating the key switch to the OFF position. During 15 seconds the
PROBA110 beeps, before the PROBA110 is switched off and the displays
extinguish. This is to avoid a ripening program being stopped if someone
accidentally switches the PROBA110 to OFF. In that case the user has the
opportunity to switch to ON or PE again.
Please note:
To prevent unauthorized changes, it is advisable after programming to rotate
the key switch to ON and remove the key from the switch.
2.1.2 Readout clock, sensors and setpoints

If the ripening room is not ventilating at the moment, the upper display
indicates the time in hours till the next ventilation.
If there is no more ventilation, the lower display shows four horizontal bars.
Press the SET key and then the HUM/GAS key. The LED above the key
starts flashing to indicate this function is active.
If the ripening room is gassed and a gas sensor is present, the upper display
shows the remaining gassing time. This time is shown in minutes.
If no gas sensor is present and the ripening room is gassed on time basis,
the upper display shows the remaining gas supply time in minutes.
If the gas supply time has passed, the upper display shows the remaining
time of the gassing period in minutes.
If the ripening room is not gassing at the moment, but a gassing has to take
place, the display shows the time to the next gassing. This time is shown in
hours.
If no more gassing is required, the lower display will show four horizontal
bars.
Press the SET key and then the SENS/TIME key. The LED above the key
starts flashing to indicate this function is active.
The upper display shows the program clock, indicating how long the
program has run in the current day. In this example the time is 15 hours and
24 minutes.
The lower display shows the number of the present day.
Press the SET key and then the ZONE/HEAT key. The LED above the key
flashes indicating this function is active.

2.1.3 Programming and starting a ripening program
Depending on the internal settings of the PROBA110, several program steps
can be skipped. This is to prevent fixed settings having to be programmed
every time and make the programming longer than needed. In this chapter
the most extensive way is explained.
Make sure that the key switch is in the PE position.
Press the PROG key. The LED above this key starts to flash, to indicate that
the programming mode is active.
The lower display will always indicate the program setting, the upper display
will give the value of this setting.
The first setting is the program number. In the lower display appears the text
'p nr'.
The upper display will indicate the present program number, in this case
program number 3. In total, 20 ripening programs are available.
This value can be changed with the UP and DOWN keys.
By pressing the SET key, the selected program setting is accepted and will
step automatically to the next setting.
The number of days of the selected program should now be entered. The
length can vary from 1 to 9 days. In the DAY row the length of the program is
indicated by the number of LED’s illuminated.
Using the UP and DOWN keys the length of the ripening program can be
changed.
Using the SET key the number of days selected is accepted.
After the program number and the length of the program are set, gassing
can be programmed.
During programming of gassing the GAS LED flash.
For each ripening program two gassing cycles can be selected.
If a gas concentration sensor is used, the desired gas concentration in ppm
(parts per million) for the first gasification can be programmed.
If no gas concentration sensor is used, the gas supply time for the first
gasification can be programmed. The time is indicated in minutes.
If the first gasification is to be omitted, press the DOWN key until 'OFF'
appears in the display.
The length of the first gassing period can now be set. The display shows this
time in hours. During this time the PROBA110 will indicate that there is gas
present and the door of the ripening room can be locked through a door
interlock relay.
If the ripener doesn't want to gas at the start of day 1, a delay time can be
set before gasification starts. In the display this time is shown in hours. The
gasification can now be delayed for a number of hours.
When gasification is not be delayed, simply set the delay to 0 hours.

VDH Products BV Document 063319 - version 3.12 Page: 12 of 78
A second gasification can now be programmed.
If a gas concentration sensor is used, the gas concentration for the second
gasification can be programmed.
If no gas concentration sensor is used, the gas supply time is programmed
for the second gasification. This time is shown in minutes.
Should the second gasification be skipped, press the DOWN key until 'OFF'
appears in the display.
The length of the second gassing period is now set. The display shows time
in hours. During this time the PROBA110 will indicate that gas is present
and the door of the ripening room can be locked.
A delay for the second gasification can now be set. The display shows this
time in hours. This time is the delay time calculated from the end of the fist
gasification.
The delay time can be changed with the UP and DOWN keys and confirmed
with the SET key.
After programming the gasification, the ventilation or air refreshing of the
ripening room is set. For each ripening program two different ventilation
cycles can be programmed.
During gasification periods the ventilation is blocked. As soon as the
gasification period is ended, the ventilation starts immediately.
During programming of the ventilation the VENT LED will light.
First the length of ventilation for the first cycle is set. This is the time that
'fresh' air flows into the ripening room.
The ventilation time is shown in hours and minutes.
If continuous ventilation is required, the ventilation time should be increased
as much as possible. The display text in this case reads 'CONT'.
If no ventilation is required, the ventilation time should be decreased as
much as possible. The display text in this case reads 'OFF'.
Next, the ventilation interval of the first cycle is programmed. This interval
time determines how many hours are between each venting.
The interval time is shown in hours.
During a ripening program the ventilation can be switched to a second cycle.
This second ventilation cycle is programmed as follows:
A delay time is set, calculated from the beginning of the ripening program
(day 1, hour 00.00), after which it is switched over to the second ventilation
cycle.
This delay time is shown in hours.
If the second ventilation cycle is not to be used, the delay time is set to
minimum.
The display text reads 'OFF'.
The length of the ventilation for the second cycle is now set.
The ventilation time is shown in hours and minutes.
If continuous ventilation is required, the ventilation time should be increased
as much as possible. The display text reads 'CONT'.

VDH Products BV Document 063319 - version 3.12 Page: 13 of 78
If ventilation is not required, the ventilation time should be decreased as
much as possible. The display text reads 'OFF'.
Finally the ventilation interval of the first ventilation is programmed. This
interval time determines for how many hours ventilation should take place.
The interval time is shown in hours.
The setting of the temperatures for ripening program now follow. For each
day a temperature can be selected.
The lower display and the illuminated LED in the DAY row indicates which
day is being set, while the upper display shows the desired temperature
(setpoint).
The set value can be changed with the UP- and DOWN keys.
Press the SET key to accept the new setpoint and the setpoint for the next
day will appear in the display. Repeat this for all days of the ripening
program.
The STANDBY temperature (setpoint after finishing the actual ripening
program) is set while the STANDBY LED lights and the lower display shows
'STB'. Changing of the value is done in the same manner as the adjustment
of other setpoints.
If a relative humidity sensor is present, the setpoint for the humidity can now
be set. The HUM LED flashes.
The upper display shows the set value.
The RH setpoint can be changed with the UP , DOWN and SET keys.
If pressure control fans are used, the pressuresetpoint for the forward and
the reverse can be set.
The pressure setpoint can be changed with the RH, UP and DOWN
keys. First press the RH key and then change the the forward setpoint with
the UP and DOWN keys. After pressing the RH key again, the reverse
setpoint can be set.
A delay time can now be set before the actual ripening program starts. This
period is called day 0. Therefore the LED day 0 lights in the DAY row.
The day 0 time is shown in hours.
When a delay time of more than 0 hours is programmed, the temperature
regulation for day 0 can be switched 'ON' or 'OFF' by the UP and DOWN
keys and acknowledged with the SET key.
If temperature control is selected ('ON'), the temperature setpoint can, like
the other settings, be adjusted with the UP and DOWN keys.
All settings are now complete. Finally the program will ask for a start
acknowledgment. This acknowledgment is confirmed by pressing the SET
key.
By pressing the SET key for the last time, the ripening program will start.
The PROG LED lights to indicate that the ripening program is in progress
and the fruit is being ripened.
To prevent unauthorized changes, it is advisable to rotate the key switch to
ON and remove the key from the switch.
Please note:
During day 0 the PROBA110 will, if selected, start with ventilation and
regulate the temperature. If the delay time is finished or the required setpoint
is reached, the ripening program will step to day 1 and continue the
program.
The program clock will count down to 00.00 hours in day 0. The program

VDH Products BV Document 063319 - version 3.12 Page: 14 of 78
steps to day 1 and the clock will count from 00.00 hours.
While programming the PROBA110 will use the last settings of that program
as default.
If a ripening program is adjusted during programming or during the ripening
process, these changed values are default settings for the next time the
program is used.
There is an option by adjustment of the internal parameters to program
standard programs, these are then used as default for programming. These
programs can be adjusted, but the next time the program is used, the
original standard program is shown.
When certain parameters for ripening programs are always the same, these
parameters can be skipped automatically. This ensures programming is no
longer than needed. This can be done using the internal parameters.
Programming can be interrupted at any time by pressing the PROG key. The
PROG LED will stop flashing and programming will not have any effect.
If during programming no key has been pressed for more than 30 seconds,
programming will be stopped. And the programming sequence will need to
be recommenced.
Tables on the this and the next page show all programming parameters with
their range and step size.

normal operating condition.
Turn the key switch to ON. Remove the key to prevent unauthorized use.
Please note:
Depending on the internal programming of the PROBA110, a temperature
change can be configured in the following ways:
1. The new setpoint is only valid for the present day.
2. The new setpoint is valid until the next setpoint change in the
program. So that the change can be active for several days.
3. All programmed temperature setpoints of the ripening program are
changed in the same way as the present setpoint. In fact, the
temperature graph is moved up or down.
If the PROBA110 is in STANDBY mode, the new setpoint will remain active
until the PROBA110 is switched off or the setpoint is changed again.

Make sure that the key switch is in the PE position.
Press the HUM/GAS key.
The lower display shows the text 'Pr', indicating that the forward setpoint can
be changed.
The upper display shows the present pressure setpoint.
The value can be changed with the UP and DOWN keys.
After the setpoint is changed, press the HUM/GAS key to set the reverse
setpoint.
The lower display shows the text 'Pr r', indicating that the reverse setpoint
can be changed.
The upper display shows the present pressure setpoint.
After the setpoint is changed, press the HUM/GAS key to return to the normal
operation mode.
Rotate the key switch to ON. Remove the key to prevent unauthorized use.
Please note:

2.1.8 Standby
In the STANDBY mode the PROBA110 will regulate for an unlimited time on
a fixed setpoint temperature in the ripening room.
This STANDBY mode for example can be used if products other than
bananas are stored in the ripening room.
Make sure that the key switch is in the PE position.
Press the STANDBY key to switch to the STANDBY mode. The LED above
the STANDBY key starts flashing.
First set the length of the ventilation.
The ventilation time is shown in minutes.
With the UP and DOWN keys the length of the ventilation can be adjusted.

If continuous ventilation is required, the ventilation time should be increased
as much as possible. The display shows the text 'CONT'.
If no ventilation is required, the ventilation time should be decreased as
much as possible. The display text reads 'OFF'.
Next set the ventilation interval. This interval determines how often a
ventilation cycle should take place.
The interval time is shown in hours.
The STANDBY temperature is now set.
The upper display shows the set value. This can be adjusted with the UP,
DOWN and SET key.
If a humidity sensor is present, the setpoint for the relative humidity is set.

Press the SET key to stop the gasification period. The GAS LED will
extinguish to indicate that the gasification has stopped.
If ventilation is programmed, the ripening room will be ventilated.
Rotate the key switch to ON and remove the key. This prevents
unauthorized use.
Please note:
If a gasification is stopped, all programmed gasifications are stopped.
Should the first gasification be stopped and a second gasification
programmed, the second gasification will not take place.
During the ripening program it is possible to insert (once again) a gassing
period, if at that moment no gassing is taking place or gasification should
take place. These have to be stopped first.
Make sure the key switch is in the PE position.
