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.

1 Product description
The DA 175 is an actuator that is specially designed for control of air intake inlets.
The actuator is available in several variations with a tensile force of 100 kg, 150 kg, 300 kg or 600 kg.
The actuator can be set to modes ON/OFF, stepless or analogue control with a jumper on the circuit board.
These three settings can also be reserved.
The actuator can be set with an optional end stop for open- and closed positions.
The actuator has a compact design that is easy to clean.
The actuator can be controlled manually.
When the DA 175 is equipped with 24 V DC, emergency opening is possible through battery power.

3.3 Mountng the DA 175
Place the DA 175 approx. 1400 mm above the floor, i.e. so high
up that the animals cannot reach it.
Make sure that other objects in the livestock house, such as wa-
ter pipes, feed pipes, doors, windows, rafters and lighting fixtures
do not obstruct the wire drive.
Use adapter for a double line, if there is a requirement for opera-
tion of 2 rows of inlets by means of 1 DA 175.
The adapter is included in the mounting sets for DA 175 .
Mount the DA 175 at least 700 mm from the wire wheel.

4 Installation guide
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.
4.1 Cabling
Mount cables in M20 cable glands. Cable glands should point downwards if possible. Cables must be secured
outside the cabinet.
4.2 Setting the supply voltage on the power supply
Before you connect supply voltage, it is important to set the voltage in the power supply so that it
corresponds to the voltage level in the local house.
1. Set the voltage in the power supply.
2. Connect the supply voltage.
200-230 V Leave the plug in (factory setting)
100-115 V Move the plug to 100-115 V
