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

An LPC fan is an energy efficient fan unit consisting of a PM motor

with matching motor control and opimised wing design for LPC

(Low Power Consumperion) and Dynamic MultiStep systems.

All variants of LPC fans are completed at the factory, so both the

motor and fan blade match the current application.

ON/OFF fans are constructed using a standard-dimensioned AC

motor, as well as an optimized blade design.

All ON/OFF fans are completed at the factory, so both the motor

and fan blade match the current application.

ECT/DCT fans are supplied with an integrated motor and fan

blades cast in aluminum. ECT/DCT fans are used as ON/OFF fans.

ECT fans can also be used as a Triac regulated fan.

The fans are designed for mounting in exhaust units and wall exhaustion in livestock houses where the ventila-

tion system operates in the low-pressure range, i.e. in LPV, diffuse livestock houses and Combi-Tunnel live-

stock houses.

The fans bear a CE marking and have a sturdy four-point suspension.

3.3 Safety distance

If the distance from the floor to the fan blade is less than

270cm, mounting a protective mesh in the inlet bell

mouth may be required to meet the statutory require-

ments.

3.4 Position of motor controller/frequency converter

Motor controller/frequency converter must not be built-in,

covered or mounted directly on the chimney and must be

mounted on a solid, level surface.

In order to uphold protection classifications, access and

cooling, the motor controller/frequency converter must

be positioned as shown in section Mounting distances

for the motor controller/frequency converter [}14].

3.5 Mounting distances for the motor controller/frequency converter

In order to ensure access of cables and cooling of the

motor controller/frequency converter, the distances to

the surroundings must be met.

3.6 Position of motor controller/frequency converter

The motor controller/frequency converter is positioned

so that the ambient temperature is between ÷ 40 °C and

+ 50 °C.

Mount the motor controller/frequency converter as close

to the fan as possible.

Do not extend the supplied 2-meter cable.

However, for fan 1x230 V, a motor cable on 5 m can be

ordered if the 2 m is not sufficient.

The motor controller/frequency converter can be

mounted on a wooden plate fastened to a rafter on the

ceiling.

4 Installation guide

4.1 Electrical connection

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.

4.1.1 Disclaimer at retrofitting fans

In the case of retrofitting fans in an existing house, regardless of ON/OFF fans, LPC fans or frequency convert-

ers SKOV recommends that a local expert is involved in checking the electrical installations. The focus should

be on cable dimensions, overload protections, local transformers, etc. It is of outmost importance to take the fan

specifications into account and, at the same time, ensure that local requirements are fulfilled.

4.1.2 Mains supply dimensioning regarding harmonic distortion

LPC motor controllers and frequency converters function like any other electronic power converter by converting

AC to DC. As this conversion produces a non-sinusoidal current, the mains supply for the controller is affected

by harmonic distortion.

The electrician or the user of the equipment must ensure, possibly through contact with the supply company,

that the equipment is connected to a properly sized mains supply.

4.1.3 Cabling in the exhaust unit

Drill a hole in the exhaust unit duct for the fan cable and

pull it along a support to the same side as the motor con-

troller/frequency converter.

4.1.4 Cabling into the motor controller/frequency converter

In order to prevent water from running into the motor

controller/frequency converter via cables and screwed

connections, the cabling must be carried out so that it

can stand water around the cable in the gasket of the

screwed connection.
