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.

1 Product description

DOL 532 T is a climate controller specially developed for simple tunnel houses. Its functionality is reduced com-

pared to the other DOL 53X variants, in that the focus is on the functions used in tropical and subtropical areas.

Several factors make DOL 532 T especially suited for use under 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 T calculates how the animals experi-

ence 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.

10" and 7" controller display

The displays shown in this manual are from a 10" controller display where the menu overview is shown to the

left in the display. If you use a controller with a 7” display, the menus are shown in the middle of the display.

Using a 7” display you can press the menu headlines at the top

of the display to go back step-by-step in the menus.

If more steps are available that what can be shown, you can

press the 3 dots and select a menu from the appearing list.

Technical Manual 7

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.

Start-up

1. Setting and calibration.

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 Setup of operation form

3.4 View week number

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. 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.

3.6.1 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.

DOL 532 T

10 Technical Manual

3.6.2 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.

3.6.3 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.

3.7 Climate

3.7.1 Air inlet

The house controller includes different types of air intake:

Side inlet Wall inlets are regulated by a winch motor.

Tunnel inlet Tunnel openings are regulated by a winch motor.

A combination of of air inlets - side and tunnel - allows the possibility to accommodate an increasing need for

ventilation, by automatic adjustment of the ventilation mode.

3.7.2 Air outlet

3.7.2.1 Dynamic MultiStep

See section Setting of Exhaustion (MultiStep) for a general description of MultiStep.

Dynamic MultiStep makes it possible to reduce power consumption for the fans in the MultiStep system. This is

achieved by the fans' ability to run at two speeds (Low and High) and by letting them run as long as possible at

low speed.

When a low level of ventilation is needed ventilation is carried out as an ordinary MultiStep system, but the fan

output is limited so that it can only provide a percentage of the fan's maximum capacity.

All exhaust units that are set up to run only in the low area in the Dynamic MultiStep system must be able to run

at reduced capacity.

When a high degree of ventilation is required, the fan output varies steplessly from low to full speed and the

flaps are fully open.

0-10 volt output

The 0-10 V output makes it possible to run at low speeds on the

fan, and from here to run the fan steplessly up to full speed.

Low speed and Full speed

When a fan connect to a 0-10 V output has been selected, a

voltage value must be set which corresponds to the fan running

at low and full speed.

Please note that most fan types have stopped at 10 volt.

Depending on which type of fan has been selected, the voltage

is set at low speed to 4-6 volts.

For each MultiStep unit, set whether it should be activated

when the Dynamic MultiStep system runs at high speed, at low

speed or with both.

Sectional cross area Setting of house area (combi-tunnel).

Maximum air speed Read-out of the maximum achievable air velocity. It is calculated based on the max-

imum air output and the cross-sectional area of the house.

3.7.3 Heating

Room heating can be regulated as common or individual heating, depending on the number of temperature sen-

sors (not for Heat controlled by own sensor).

Common regulation: A sensor combination with a common setpoint for all room heaters

Individual regulation: A sensor combination for each room heater.

Heat control

(only house heaters)

Choose whether heat sources 1 and 2 should start in parallel or sequentially.

Heat distribution Distribution of capacity between heat sources 1 and 2 (for separate heat control only)

Sequential heating is typically used when there are two different heat sources in the

house.

For example:

• heating pipes and air heaters

• heating pipes and blow heater as extra capacity

It is important to distribute correctly between the two types of heat sources, in order to

obtain a steady heat control. The heating system’s dimensions and output determine the

actual distribution.

3.7.4 Setup of sensors

Temperature sensor se-

lection

Location of temperature sensors for ventilation and heat control.

You can set up several temperature sensors in the livestock house to register the

temperature in each zone.

Tunnel cooling sensor

setup

Selecting which temperature sensors should be used for controlling tunnel cooling.

Tunnel cooling sensor: A dedicated temperature sensor for tunnel cooling.

For this type of adjustment, the sensor must also be set up for tunnel cooling alarm

and cooling control, respectively.

Tunnel temperature: An average from the temperature sensors measuring tunnel

temperature.

Temperature sensor: A temperature sensor placed appropriately for tunnel cool-

ing.

3.7.5 Active Functions in the Event of Control Failure

When installing MultiStep air outlet and side cooling, you must decide how these functions is to react in an

emergency situation.

4 Calibration

4.1 Calibration of Air Intake and Air Outlet

The controller must be adapted to the winch motor after installation.

Winch motors with feedback must be calibrated by a technician, while winch motors without feedback are cali-

brated automatically once the technician has set up a time for Air inlet time.

During the automatic calibration, the air inlets/air outlets open and close completely for a short time and then re-

turn to the position which the controller calculates.

The change-over switch on the winch motor must be se to AUT.

4.1.1 Winch motor without feedback

Time Setting of the time of day when the automatic calibration shall run.

Running time Setting of the time it takes to run from fully open to fully closed.

Runs before recalibra-

tion

Setting of the number of times the inlet flap has to run before it calibrates automati-

cally.

Minimum voltage

Maximum voltage

When the air inlets or air outlets are 0-10 V controlled, the output voltage can be ad-

justed via Min. voltage and Max. voltage.

1. Select the menu Technical | Calibration | Climate | Side inlets | Calibration.

2. Select ON to start calibration.

3. Check that the correct inlet(s) open(s) and close(s) correctly.

4. Wait until the calibration is finished and the display shows Calibration ended again.

Calibration of other air inlets and air outlets are carried out in the same way.

4.2 Calibration of climate sensors

Temperature and humidity

The connected temperature and humidity sensors can be calibrated using an offset.

If, in connection with manual measurements, the current value is measured to a level that differs from the regis-

trations provided by the installed sensors, you can adjust the read-out value so that it corresponds to your ob-

servation.

0-10V sensors

Adapt the controller to the sensors after installation.

When a sensor is 0-10 V controlled, you can adjust the output voltage via Minimum voltage and Maximum volt-

age.

When Min. value and Max. value are set, you should also indicate the range within which the sensor can mea-

sure.

4.2.1 Calibration of pressure sensor

Depending on the control type (positive pressure/negative pressure), for which the DOL 18 is to be used, it must

be installed and adjusted in different ways.

When installing the pressure sensor, dip switches must be set up and tubes must be placed. Also see the Cir-

cuit Diagrams and Cable Plans document.

Setting the minimum and maximum values must only be done

when setting up the sensor.

4.2.2 Calibration of CO2 sensor (installed as CO2 sensor)

The CO2 sensor should be checked between each batch when the house is in Empty house.

If the CO2 sensor is installed as an auxiliary sensor (for emission measurement), it must be calibrated as de-

scribed in the section Calibration of CO2 sensor (installed as auxiliary sensor) [}17].

1. Replace the air in the house in Empty house mode by running with 100% exhaust and 100% open inlets for

at least 20 minutes.

The reading of the CO2 level should now be 500 ppm +/- 100 ppm or the same value as the atmospheric air

+/- 100 ppm.

2. Check if the reading deviates more than +/- 100 ppm from 500 ppm (or from the same value as the atmo-

spheric air value).

If the reading deviates more than +/- 250 ppm, the sensor should be replaced.

Offset calibration of CO2 sensor

The sensor can only be calibrated when there are no animals in the house and it has been thoroughly venti-

lated.

Calibration should always be carried out in relation to atmospheric air and not in relation to other types of CO2

sensors.

See the menu Technical | Calibration | Climate | CO2 sensor.

1. Adjust the Calibration offset until the read CO2 value shows 500 ppm.

The other values must not be changed.

Note: Calibration should only be carried out only by staff trained by SKOV.

4.2.4 Calibration of NH3 Sensor

If DOL 53 does not measure correctly, normal maintenance is carried out (replacement of filter). The sensor

must be changed if this does not help.

DOL 532 T

18 Technical Manual

5 Testing

After installation of the system a thorough test must be carried out, to ensure that the system works as intended.

5.1 Testing basis components

5.1.1 Testing temperature and air humidity sensors

Read the current inside temperature and humidity

1. Check that the temperature displayed corresponds to what you can measure in the house/outside.

2. Check that the temperature increases in the display when you warm the sensor in your hand.

3. Check that the humidity displayed corresponds to what you can measure in the house.

4. Check that the humidity rises when you breathe on the sensor, for example.

5.1.2 Testing Alarm

Select Alarm settings.

Activate Alarm test to start testing.

Check that the alarm lamp is flashing.

Check that the alarm system alarms as intended.

Press Acknowledge to finish testing.

The test should then be made every week.

5.1.3 Testing emergency opening

See the Technical Manual for the emergency opening.

5.2 Testing optional components: Manual control

During testing, and in a service situation, the individual components connected to the climate or production con-

troller and be switched from automatic to manual control. Thus, you can easily test the optional components

such as winch motors, etc.

In the menu Manual/auto the house controller displays the components selected in the menu Installation.

Automatic control: Normally the controller must be set to automatic control.

Manual mode: During start up, or in a service situation, it may be convenient to control the individual functions

manually.

DOL 532 T

Technical Manual 19

The component currently set for manual control are listed in the

menu Technical | Manual/Auto | Manual mode.

The manual control can also be deactivated here.

Select the function to be tested and test the components one at

a time.

A colored bar at the top of the page indicates that a component

is set for manual mode.

After testing the components, you must set the function back to automatic control, so that the house

controller continues to operate as before.

I/O will remain in the setting that it was on at the moment the component was set to manual. This means that

operation continues when it is returned to automatic control.

5.2.1 Testing Climate Functions

5.2.1.1 Testing Air Intake and Air Outlet

The test is to show whether air inlet and air outlet can open and close completely.

Select the menu Technical | Manual/auto.

Then select Climate | Air inlets | Side Inlet 1 and activate Manual mode.

Set Side inlet 1 requirement to 100 %.

Check that the correct air inlets open completely.

DOL 532 T

20 Technical Manual

Set Side inlet 1 requirement to 0 %.

Check that the correct air inlets close completely.

Set the air inlet to the required setting.

Repeat the test for the installed air inlets and outlets.

5.2.1.2 Testing of Dynamic MultiStep

The testing of Dynamic MultiStep is done in the same way as described for MultiStep. See section MultiStep

[}21].

The testing of fans for Dynamic MultiStep is done in the same way as described for Stepless fans. See section

Stepless fans [}20].

5.2.1.3 Stepless fans

Testing setting and placement of stepless fans

The test is to show if the connected stepless fans are set correctly, i.e. if they can run at minimum and maxi-

mum speeds, and whether they are placed correctly.

In internal fan speed controller mode, the emergency change-over switch AUT/MAN (automatic/manual) on the

side of the controller must be set to AUT (see the section Emergency Change-over Switch AUT/MAN [}21]).

Select the menu Technical | Manual/auto.

Then select Climate | Air outlets | Stepless 1 and activate Manual mode.

Set the Air outlet 1 required (flap) to 100 %.

Activate Manual mode for Air outlet fan speed and set the Air

outlet fan speed to 100%.

Check that the fan is placed in the livestock house.

Check that the fan sucks air out of the house (e.g. by means of

a smoke test).

Check that the fan is running at maximum speed.

Set the Air outlet fan speed to 1 %.

Check that the fan sucks air out of the house (e.g. by means of

a smoke test).

Check that the fan is running down to minimum speed.
