IMPORTANT
NOTES CONCERNING THE ALARM SYSTEM
Where climatic control is used in livestock buildings, breakdowns, malfunctions or faulty settings may
cause substantial damage and financial losses. It is therefore essential to install a separate, independent
alarm system, which monitors the house concurrently with the house computer. According to EU
directive 98/58/EEC, an alarm system must be installed in any house that is mechanically ventilated.
Please note that the product liability clause of Big Dutchman' general terms and conditions of sale and
delivery specifies that an alarm system must be installed.
In case of maloperation or improper use, ventilation systems can result in
production loss or cause loss of lives among animals. Big Dutchman recommend
that ventilation systems 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 Big Dutchman terms and
conditions of sale and delivery.
The functioning of our house computers is critical for the animals' well-being. So
we place considerable focus on ensuring the computers' operations. One important
parameter for satisfactory operations is good follow-up.
All Big Dutchman computers with internet access report daily to our operational
staff regarding the computer's general condition, CPU load, memory consumption
and operating times. This enables us to find negative trends and thereby to remedy
an error before it becomes critical.
•All rights belong to Big Dutchman. No part of this manual may be reproduced in any
manner whatsoever without written permission from Big Dutchman.
•Big Dutchman have made reasonable efforts to ensure the accuracy of the information
contained in this manual. Should any mistakes or imprecise information occur in spite of
this, Big Dutchman would appreciate being notified thereof.
•Irrespective of the above, Big Dutchman shall not have any liability with respect to loss or
damage caused or alleged to be caused by reliance on any information contained herein.

4 Mounting of Climate Sensors
Never use a plug on the DOL 12 temperature sensor as a bad connection here
could have disastrous results.
Always use reinforced house wiring cable, minimum 1.5 mm2, to avoid
rodent attack.
Never use shrink-on sleeves when splicing wires inside the livestock house.
Use a contact box.
Placement of sensors inside the house
Place the sensor in the centre of the house.
In case of animals on floor the sensor is placed 1 metre over the animals (make sure the animals
cannot reach sensors).
Two-climate houses: the sensors must hang halfway between the covered area and the slats.
Remember that temperature, humidity, alarm and emergency sensor should be placed together, if
possible use house board for sensors (available as accessory).
The sensor is not to be placed
Reason
Above penning equipment.
The animals may be able to reach them.
At feed dispenser/feed trough/transponder station.
Heat and humidity will rise to the position of the
sensors.
Near covering.
Heat from the covered area will rise to the position of
the sensors.
Near spraying system.
Water and humidity will affect the sensors.
Near cooling system.
Water and humidity will affect the sensors.
In a draughty area. The sensor is not to be directly
affected by the air intake.
Measures the wrong temperature in the house.
Not where sunrays can shine on the sensor through
windows.
Take into account that the altitude of the sun varies
with the season/time of day.
Measures a too high temperature. Too much
ventilation.
Above electric heater in the section.
The heat rises to the position of the sensors.
Above or in a position where it in some way will be
affected by the heating system/heating pipes.
The heat rises to the position of the sensors.
Placement of sensors outside the house
We recommend mounting sensors with a radiation shield (available as accessory).
On the shady side of the house to avoid the sun. Take into account that the altitude of the sun varies
with the seasons.
As much in the open as possible, but protected from rain and snow.

5.4 Connection of extra 24 V power supply
Internal power supply (A) may only supply factory-installed modules.
In case of a greater power consumption than 0.8 A from the loop module (B), an extra power supply (C) must
be used and possibly (D).The A5 minus terminal is connected in parallel (terminal A5 to A5).
Figure 10: Connection of extra 24 V power supply
Connect power supply to 307pro with a multi-conductor cable.The connected products determine the number of
conductors in the multi-conductor cable.

Having set up the installation menu using the PC simulator, the setup can be saved as a semicolon delimited file
on the PC. The file thus contains a list of the installed components and the connection terminals to which they
are to be connected in the house computer.
The file can be opened using MS Excel or a text editor
and be printed in the usual way.
Open the PC simulator and select the Setup menu.
Choose where to file the setup file.
USB drive:
Corresponds to the house computer's filing of e.g.
log files and setup files on a USB flash drive.
Can be set in the PC simulator to save on a USB
flash drive or locally on the PC.
Folder:
You can also choose to save the file in a folder.
Save the file using the name: ConnectionList.csv.
Each time the user enters the
Technical/Setup/Show connections menu, the
PC simulator saves a version of the current setup
on the file.
If the file already exists, it will be overwritten.
There can only be one ConnectionList on the
same USB.

7.1 Settings for Winch Motor
When you connect winch motors, the following must be set as shown in: Technical/Setup/Show installation.
LO-power relay module:
Winch motor YES / NO, jumpers W1 - W5:
•YES= Inverts one of the relays in the pair of relays
so that it matches winch motor and emergency
opening
•NO = The relay matches e.g. heating and fans.
Override switch modules:
WINCH-MOTOR BLOCKED: slide switch: S1 - S5
•ON = For winch motor. Prevents paired activation
of relays and quick changes in direction out of
consideration for the lifetime of the relay contacts
•OFF = For e.g. heating and gable fans. The relays
can be activated unobstructed.
•A winch motor must always be installed on one of the following pairs of relays: 1st + 2nd relay, 3rd +
4th relay, 5th + 6th relay, 7th + 8th relay or 9th + 10th relay
•The HI-power relay module with make contacts can control e.g.
fan
heating
230 V winch motor
•The LO-power relay module with make contacts can control e.g.
fan
heating
230 V winch motor
24 V DC winch motor with emergency opening
•The switch module is used together with both the HI-power relay module and the LO-power relay
module

Example:
If a 24 V winch motor is installed on 9th and 10th relay, the following must be set:
•Set the W5 jumper on the LO-power relay module to YES
•Set the S5 slide switch on the override switch module to ON
There are no settings on the HI-power relay module and it cannot control 24 V winch motors either.
