IMPORTANT
Notes concerning alarm systems
Breakdowns, malfunctions or faulty settings may cause substantial damage and financial losses when regulat-
ing and controlling the climate in a livestock house. It is therefore essential to install a separate, independent
alarm system that monitors the house climate concurrently with the climate and production controller. According
to EU-directive No. 98/58/EU, an alarm system must be installed in all mechanically ventilated houses.
We would like to draw your attention to the fact that the product liability clause of general terms and conditions
of sale and delivery specifies that an alarm system must be installed.
In case of an operating error or inappropriate use, ventilation systems can result in production
losses or cause loss of lives among livestock.
We recommend that ventilation systems should be mounted, operated and serviced only by
trained staff and that a separate emergency opening unit and an alarm system be installed as well
as maintained and tested at regular intervals, according to terms and conditions of sale and deliv-
ery.
Installation, servicing and troubleshooting of all electrical equipment must be carried out by quali-
fied personnel in compliance with the applicable national and international standard EN 60204-1
and any other EU standards that are applicable in Europe.
The installation of a power supply isolator is required for each motor and power supply to facilitate
voltage-free work on the electrical equipment. The power supply isolator is not included.

DOL 532 Tunnel
6 Technical Manual
1 Product description
DOL 532 Tunnel is a climate controller specially developed for simple tunnel houses. The focus is on the func-
tions used in tropical and subtropical areas. Several factors make DOL 532 Tunnel especially suited for use un-
der these climate conditions.
The ventilation is not only regulated according to the current inside and outside temperature, but also to the
cooling effect of the air speed - the chill effect. This means that DOL 532 Tunnel calculates how the animals ex-
perience the temperature in the house and adapts the ventilation accordingly.
The pad cooling is regulated on the basis of an intelligent control, which ensures an optimal use of the supplied
water. Together with the precise control of different types of heat sources, this provides the conditions for
achieving a better climate throughout the entire livestock house.

Technical Manual 7
2 Work routine
This technical manual deals with the installation of the controller 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 workflow regarding set up of the controller.
Mounting
1. 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 controller menu Installation | Installation wizard by reviewing all the in-
stallation menu items in the Installation wizard.
5. Connect the individual components by means of the controller's menu Installation | Show connec-
tion and the circuit diagrams.
6. Adjust the system.
7. Test the system.
Start-up
1. Setting and calibration.

3 Installation guide
3.1 Selecting components
There are two ways to install the controller.
At the initial installation: Use Installation wizard which will guide you through all the options of the functions.
If making adjustments to the existing installation: Use the menu Manual installation to go directly to the rel-
evant function.
Select components in the installation menu of the controller.
Installation | Installation wizard or Manual installa-
tion.
It is impossible to select more components than there are avail-
able I/O.
Therefore, you must observe that the controller accepts your re-
quests 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 set-up menus Installation
and Show connection, all alarms will be delayed. Thus, no
alarms will be generated until 2 minutes after the last change is
completed n the installation menu.
It is indicated as info in the alarm menu for as long as the delay
is active.
However, it does not apply to alarms from CAN bus communi-
cation (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 Setup of operation form
Operation form Setting of operation form (continuous/batch production).

View week number View of week number at the top of all pages.
3.5 Select type of Unit of measurements
Unit of measurements The controller can display the units as both metric and US units.
3.6 Connecting components
The majority of the connection terminals are universal. Therefore, installing different components in the individ-
ual terminals is possible.
When you select a component from the menu Installa-
tion | Manual installation, the controller allocates I/O based on
a list. It means that the controller selects the first available I/O
on the list and that the components are allocated I/O in the or-
der 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.
3.6.1 Installation wizard
The installation wizard starts automatically the first time you activate the controller. The wizard provides a struc-
tured walk-through of the installation of the controller functions. We recommend that it be used for installation.
It supports the necessary selections and settings to set up the controller.
Choose between:
•Installation wizard: A complete installation walk-through.
•Manual installation: Installation or adjustment of a specific
function, for example, cooling. A few changes can be saved
here.
Press the buttons in the upper right corner to move one step
forward or backward in the installation.
Press the X in the upper left corner to finish the installation be-
fore completing all steps.
Press Cancel to finish without saving.
Press Confirm to save changes.
Also, see the section Work Routine for an overview of the com-
plete procedure of setting up the controller.

3.6.2 The menu Show connection
When you have selected all the components in the installation menu, the controller will show you where to con-
nect 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.
3.6.3 Manual I/O allocation
If you want to determine the I/O allocation for one or more components, you can manually change it under the
menu option Manual I/O allocation.
Select the menu Installation | Manual I/O allocation
and press the component to be changed.
Choose between the listed terminals. Note whether a terminal is
already allocated to another function.
Press the required terminal.
If you use a terminal currently used by another function, the
controller will change the I/O allocation for this function.
In the menu Show connection, ensure that the controller moves
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 controller will accept it.
If the I/O allocation cannot be changed, the controller will reject
it, and the I/O allocation will remain unchanged.
