1 Product description
DOL 63X is a series of one- and two-house controllers developed especially for pig houses. The controller se-
ries includes several variants. Each of them meets the different requirements for climate and production control
in connection with the production forms and geographical climatic conditions.
• DOL 634 climate controller
• DOL 635 production controller
DOL 634 is available in the following software variants:
• LPV
• T (Tunnel)
• CT (Combi-Tunnel)
• Basic
• CE (Central exhaust)
• N (Natural ventilation)
DOL 635 is available in the following software variants:
• S (Small)
• L (Large)
DOL 635 includes production functionality such as dry feeding, water, light and 24-hour clock, while DOL 634 in-
cludes the basic production features such as light, water and 24-hour clock.
A combination of climate and production functionality can be achieved by combining DOL 634 and DOL 635
system software. This controller is called DOL 639.
The controller is operated via a large touch display with graphical views of the ventilation status, icons and
curves, among other things. The pages shown in the display may be adapted in accordance with the user re-
quirements so that the most frequently used working procedures are easily accessible.
DOL 63X has two LAN ports for connection to FarmOnline and two USB ports.
10" and 7" controller display

2 Work Routine
This technical manual deals with the installation of the controller and and is aimed primarily at the technicians
and electricians who will be mounting, installing and testing the controller.
According to current national and in Europe also EU regulations, the installation must be carried out by expert
personnel.
Note that electrical equipment may not be opened without removing the supply voltage, and only competent per-
sonnel may carry out servicing operations and troubleshooting.
The following checklist indicates the main points of the work flow regarding set up of the house controller.
Mounting
1. House controller.
2. Emergency opening, if applicable.
Installation
1. Connect cables according to the circuit diagrams for the emergency opening of the system.
2. Set voltage in the controller.
3. Connect mains voltage to the controller.
4. Select components in the house controller's menu Technical | Installation | Installation wizard by
reviewing all points in the Installation Installation wizard.
5. Connect the individual components by means of the controller's menu Technical | Installation |
Show connections and the circuit diagrams.
6. Customize the controller page views to show precisely those functions and values used in the individual
house.
7. Adjust the system.
8. Test the system.

3 Installation guide
3.1 Selecting Components
There are two ways to carry out installation of the controller.
At the initial installation: Use Installation wizard which will guide you through all the options of the functions.
At adaptation of the existing installation: Use the menu Technical | Manual installation which enables you
to go directly to the relevant function.
Select components in the installation menu of the controller.
( Technical | Installation | Start installation or Manual
installation).
It is not possible to select more components than there is avail-
able I/O for.
You must therefore be aware of whether the controller accepts
your wish to connect a component
If missing I/O, you can:
• install extra I/O modules (if these are available).
• uninstall components.
While functions are selected in the Installation and Show con-
nections setup menus, all alarms will be delayed. Thus, no
alarms will be generated until 2 minutes after the last change in
the installation menu.
This is indicated as info in the alarm menu for as long as the
delay is active.
This does not apply to alarms from CAN bus communication (I/
O modules).
3.2 Slave relays
Using slave relays, the power may be distributed on multiple relays. This is especially useful if the power load is
larger than the max. current of the relays.
For several functions it is possible to select a slave relay which will work in the same way as the master relays -
however, with a delay of up to 1 sec. When the controller is set to Manual, the slave relays will also follow the
master relays.
For heating - when the master is 0-10 V output, the slave relay relay will switch on when the heating is switched
on.
3.3 Select type of Unit of measurements
Unit of measurements The controller can display the units as both metric and US units.

View week number View of week number at the top of all pages.
3.5 Connecting Components
The majority of the connection terminals are universal. Different components can therefore be installed using
the individual terminals.
When you select a component from the menu Technical
| Installation | Manual installation the house controller allo-
cates I/O on the basis of a list. This means that the house con-
troller selects the first available I/O on the list, and that the com-
ponents are allocated I/O in the order they are selected.
The same I/O allocation in several controllers – i.e. when the in-
dividual components are connected to the same terminal num-
bers – is ensured by saving the set-up on a USB stick and en-
tering the set-up into several controllers.
3.5.1 Installation wizard
The installation wizard starts automatically when you switch the controller on for the first time. The wizard pro-
vides a structured walk-through of the installation of controller functions. We recommend using the wizard for in-
stallation.
Thus it supports that necessary selections and settings are made in connection with the controller setup.
Choose between:
•Technical | Installation wizard: A complete installation
walk-through.
•Technical | Manual installation: Installation or adaptation of
a specific function, for example, cooling. Here individual
changes can be saved.
Press the arrow buttons in the top right corner to move one step
forwards or backwards in the installation.
Press the X in the upper left corner to terminate the installation
before all steps are completed.
Press Cancel to finish without saving.
Press Confirm to save changes.
Also see section Work Routine for an overview of the complete
procedure for setting up the house controller.

10 Technical Manual
3.5.2 The menu Show Connection
When you have selected all the components in the installation menu, the house computer will show you where
to connect the individual components.
See the menu Show connection for where exactly to connect the individual components.
When a wiring diagram in the Circuit Diagrams and Cable Plans reads "See Show connection", it refers to this
menu.
3.5.3 Manual I/O allocation
If you want to decide the I/O-allocation for one or more components yourself, you can change it manually under
the menu item Manual I/O allocation.
Select the menu Technical | Installation | Manual I/O
allocation, and press the component to be changed.
Choose between the listed terminals. Please note if a terminal
is currently allocated to another function.
Press the required terminal.
If you use a terminal that is currently used by another function,
the house controller will change the I/O allocation for this func-
tion.
Check in the menu Show connections that the house controller
has moved the first allocated function to another terminal.
The controller will change the I/O allocation instantly.
If the I/O allocation can be changed, the house controller will
accept it.
If the I/O allocation cannot be changed, the house controller will
reject it, and the I/O allocation will remain unchanged.

3.5.4 Shared equipment
Controllers in the same network (see Network settings [}31]) can share equipment such as outside tempera-
ture sensor and outside humidity sensor.
The controller where the equipment is physically connected is called the ‘Master’. The other controllers are
called ‘Clients’.
A climate or production controller may be the’ Master’ of connected equipment while it is also the ‘Client’ of
equipment connected to another controller.
If the connection between the controllers is lost, an alarm appears on both the ‘Master’ and the ‘Client’
controller.
Example of shared outside temperature sensor - setup in ‘Client’ controller
Select the menu Techical | Installation | Manual in-
stallation | Climate | Sensors | Temperature sensor
Activate Use shared outside temperature sensor.
Select the controller where the outside temperature sensor is
connected.
The name of the controller providing the outside temperature is
shown in the display.
3.6 The menu Installation
3.6.1 Light control
The main light can be fitted with a light dimmer.
The light control consists of two different types of light: main light and inspection light.
Light dimmers with relays are used in houses, where the light source used cannot be switched off by means of
the dimmer alone.

Use boost This is used for light fixtures that cannot be switched on unless they start at maxi-
mum power for a short period of time.
Max. light intensity Setting how wide a scale you should be able to adjust the light within. This en-
ables you to adapt the light control to the type of light source used in the house.
The scale can be set from 1-1000 lux and the factory setting is 100 lux.
Inspection light Setting up if inspection light is available or not.
Inspection light settings Duration: Setting an active period and light sources for the inspection light.
Active: Activation or deactivation of inspection light.
Light intensity: When a light source has been installed with a light dimmer, a re-
quired light intensity (lux) for the inspection light can also be set.
Light dimmer boost time Setting the duration of the boost when the light is turned on.
When light has been installed with a light dimmer, it can turn on using a so-called
boost. It means that it turns on with the maximum intensity and that it then adjusts
according to the setting.
Light active at failure Setting if the light should switch on at power failure.
When installing light you must decide how the function is to re-
act in an emergency situation.
Yes: In case of control failure, the light is on.
No: In case of control failure, the light is off.
3.6.1.1 Light sensor
When using a light dimmer, the light can be controlled by a sen-
sor.
The light sensor is also used for alarming purposes.
Select which sensor type to use.
If Other Sensor is selected, it must be calibrated.

3.6.2 Feed control
The production controller supports a dry feeding system with two feed lines, each of which can be extended with
a subcircuit. The two feed lines may share a feed weigher and feed program or have separate feed programs. In
systems that require exact feed supply, volume dispensers may also be used.
3.6.2.1 Feed
Time to empty feed line 1 Setting the time the feed chain must run to empty the chain. The time is set to en-
sure that the chain is not worn unnecessarily.
Time for no feed on feed

Setting the time that the feed stop sensor must be free of feed before the feed
supply starts.
Time for feed on feed stop
sensor
Setting the time that the feed stop sensor must be covered by feed before the
feed supply stops.
Run in empty house Usually, the feeding system will not run when the batch status is Empty house. In
houses where the feed system also supplies feed to other sections, you can let
the system run and alarms be active also when the batch status is Empty house.
Use separate feed pro-
grams
For two feed lines without feed separation shutter.
Use two feed programs if feeding is not to take place at the same time for both
feed lines.
Stop feed system if no
feed is supplied
Setting the time when feeding must stop to ensure that the chain does not run
when it is empty.
Status changes into Waiting for feed supply. The feeding is automatically re-
sumed when there is feed in the chain again.
Minimum time to next fill-
ing
Setting the minimum time between a feeding stopping and the next one starting.
The pause should ensure that the animals are not fed too often as this will lower
the productivity.
Note that the settings must be adapted to the times in the feed programs.
3.6.2.1.1 Dry feeding - with two feed lines and feed distribution shutter
Two feed lines are used in feed systems where it is necessary to increase the feeding system’s capacity or
where there are animals in different age groups, that requires different types of feed.
1. Silo auger
2. Feed weigher
3. Feed separation shutter
4. Feed demand sensor
5. Winch motor
6. Feed stop sensor
7. Volume dispenser
8. Wire/chain system
Figure1: The two feed lines stop based on the input from the feed stop sensor of the feed line.

DOL 635 • DOL 639
14 Technical Manual
Different types of feed may be fed to the two feed lines in sys-
tems with two feed lines and a feed separation shutter located
below the feed weigher. The feed is delivered to feed line one
or feed line two, according to the position of the shutter.
If there is no feed separation shutter, separate feeding may be
achieved on the two feed lines by setting up a feed program for
each feed line. See also Feed [}13].
3.6.2.1.2 Subcircuit
In systems where it is necessary to extend the feed line, a subcircuit may be used. The two chains each have
their own winch motor and sensors and run in turns to fill and empty the feeding system.

The settings for the stop sensor are shared by subcircuits.
Time for no feed on sub-
circuit start sensor
Setting the time where the controller monitors that the chain is running. This is
done by monitoring if the feed is removed from the start sensor.
If the chain runs beyond this time, the controller gives and alarm and feeding is
stopped.
Time for feed on subcir-
cuit start sensor
Setting the time that feed must be at a sensor before the subcircuit is started.
The start offset must ensure that the detection of feed is stable.
Time to empty subcircuit

Technical Manual 15
3.6.2.1.3 Dry feeding - monitoring of feed chain
The production controller can monitor the feed chain, as well as
trigger an alarm and stop the feeding if errors occur.
A 0-10 V input terminal is required for each type of monitoring.
Monitoring of feed chain errors
Errors are registered via an input provider.
Monitoring of feed chain ceases to operate
If the feed chain stops in the middle of a feed program, it can be
registered via a pulse signal or an input provider.
3.6.2.1.4 Volume dispenser
Empty volume dispenser 1
button
Selecting an external button for manual emptying of the dispenser.
It is not possible to empty the volume dispensers while feeding.
Duration for opening/
closing dispenser line
Setting a time for opening and closing of volume dispensers.
Opening and closing takes place immediately after each other in this order:
• Closed
• Opens (20 sec.)
• Open (2 sec.)
• Closing (20 sec.)
The time can be adjusted for each feed line.
3.6.2.2 Feed weighers
3.6.2.2.1 Shared feed weigher - via controllers in the same network
These feed weighers: DOL 9940, drum weigher or electronic silo weigher can be shared via the net-
work.
A feed weigher may be shared by up to 8 controllers, when the controllers are connected to the same network
(LAN) (see Network settings [}31]). The controller with the feed weigher connected is set up as ‘Master’, the
other controllers as ‘Clients’. See the section Shared equipment [}11]. Any silos and silo weighing must be con-
nected to and installed on the ‘Master’ controller.

DOL 635 • DOL 639
16 Technical Manual
Each controller must have its own cross auger.
The feed weigher cannot have a feed separation shutter.
When feeding or filling in one livestock house has finished, the feed weigher is release for use in another house.
The status of the feed weigher can be seen in the menu | Production | Feed weigher as well as Produc-
tion | Shared feed weigher.
The ‘Master’ controller can show the combined feed consumption for all houses and the current silo content.
Silo deliveries must also be entered in the ‘Master’ controller.
Each controller shows the consumption in the house in question, just as the feed programs are set up in each
individual controller.
When using dry feeding and electronic silo weigher as feed weigher, a feed demand sensor and supply
auger must also be installed.
Supply auger must be installed with all weigher types.
3.6.2.2.2 Shared feed weigher with separation shutter
DOL 9940 or drum weigher
A feed weigher can be shared between two house controllers. One house computer is to be set up as the con-
trolling computer. This means that this house controller controls the distribution shutter of the weigher. For this
purpose, it uses a relay. Both house controllers use an input (sharing signal) and a relay (request relay) to sig-
nal to each other whether or not they are currently using the feed weigher.
Uses the feed weigher Does not use the feed weigher
Controlling house computer Distribution shutter. Relay ON
Distribution shutter position: 10 V

When feeding is required, turn on
the relay for 10 seconds every 2
minutes
Shared signal 0 V. If the second house wishes to
use the weigher, the signal will in-
crease to 10 V for 10 seconds ev-
ery 2 minutes.
The shared signal is 10 V
Signals for shared feed weigher.
In addition, each controller has its own feed demand sensor, cross auger relay, cross auger supply sensor and
silo augers.
Furthermore, a number of silos are installed for each controller.
A shared feed weigher must be calibrated in both controllers (it is possible to copy the calibration value
from one controller to the other).
3.6.2.2.3 Shared silo
The function Shared silo can only be used on farms where the production controllers are connected through a
LAN network and where the management program FarmOnline Explorer is used.
A silo that supplies feed to several houses should be regulated and divided by the production controllers in the
different houses.
When a silo is divided between different production controllers in such a way, the consumption/delivery for one
production controller is transferred to the others as a change in the current silo content.

DOL 635 • DOL 639
Technical Manual 17
The following common values apply:
1. Silo content The production controller automatically reduces the silo content with an amount corresponding
to the animals' feed consumption.
2. The user adds the amount of feed delivered to one of the house controllers manually and the other house
controllers update the silo content automatically. However, the value of the amount of feed delivered is only
available in the delivery log on the house controller it was entered on.
3. Tare. The user can change the current silo content. It can be set to any value, but the function is most often
used to ensure that the production controller records an empty silo as having a silo content of 0.
The production controllers should be on the same LAN network. In the management program FarmOnline Ex-
plorer, the production controller should be a part of the same configuration. This way they get access to data
from each other. See the section Network settings [}31] for the setup of the production controllers on a net-
work and see the FarmOnline Explorer Technical Manual for creating a configuration. The workflow is as fol-
lows:
1. Connect the production controllers to the LAN network.
2. Create a configuration in FarmOnline Explorer, where the controllers are included.
3. Create and name the shared silo in one of the controllers.
4. Select the silo in the other controllers.
All silos can be used as shared silo. The setup of silos should be carried out in all the connected controllers.

DOL 635 • DOL 639
18 Technical Manual
First select the number of silos.
Then, under the heading Silo settings, select if the silo should
be shared with other production controllers.
Set the silo to be shared.
This is done by selecting Create silo.
The name of a shared silo should be unique at the farm to
make it possible to tell the silos apart.
When a shared silo has been created, is should be selected
from the other controllers to set up the connection between
them. This is done by clicking Attach.
The shared silo with the new name is displayed in the produc-
tion menu.
Silos cannot be shared if electronic silo surveillance is activated or an electronic silo is selected as feed
weigher.
3.6.2.2.4 Electronic silo weighing
Start by selecting Electronic silo weigher followed by the number of Silos for feed weigher.
Please note that silo weighing boxes must be installed before electronic silo weighing can be selected, see also

A stable weighing signal is important to achieve a correctly registered feed consumption, feed supply and silo
weight.
Therefore, the following conditions must be considered when installing
• Signal cables from the load cells to the load amplifier must be as short as possible. However, all cables
must have the same length.
• The signal cable from the junction box to the load amplifier must be as short as possible.
• Shielding must be connected at all load cells, in junction box and in load amplifier.
• There must be a least 1 meter from the signal cables to the supply / power cables.
• CAN bus cables from the load amplifier to the controller must be as short as possible, and shielding must be
connected.
• There must be a least 1 meter from the CAN bus cable to the supply / power cables.
• All load cells must be connected to the same ground.
• The silo must “float” in the mechanical mounting.
• The silo must not slope more than 1 %.
