Electrical And Control Equipment - Swegon GOLD SD Description

Description of the Air Handling Unit

Electrical and Control Equipment

General
The electrical and control system is completely integrated
into the air handling unit. The microprocessor-based
equipment controls and regulates temperatures, airfl ows
and other functions. A large number of functions are built
into the system and are simple to activate.
The air handling unit can be automatically controlled in
several ways via the built-in timer or main control system,
however it can also be demand-controlled e.g. via a
CO sensor. Manual control is also possible.

A large number of functions and settings can be acti-
vated/entered via a main control system.
Control Inaccuracy:
Temperature ± 1 C.
o
Airfl ow ± 5%.
Power Effi ciency
The design and performance of the air handling unit are
optimized for achieving excellent power effi ciency.
Standards
The unit meets the provisions of the ELSÄK-FS 1999:5
and SS-EN 60204-1 electrical safety standards. Protection
class IP 54.
Interference Level
The unit meets the requirements defi ned in the EMC
Directive and has been tested according to the provi-
sions in EN 61000-6-2 and 61000-6-3 (electromagnetic
emissions in dwellings, offi ce buildings, shops and similar
environments as well as for immunity in industrial environ-
ments).
Use of an earth fault circuit breaker
The earth fault circuit breaker, if required, should only
serve the air handling unit and must be of a type
designed for use with the control system of the EC motor.
Control Unit – GOLD SD
If both GOLD SD supply air and extract air handling units
are used in a ventilation system, the supply air unit is
fi tted with a control unit and the extract air unit is with-
out. A communication cable is used to connect them to
one another making it possible to control both units.
Electrical and Control Equipment
On the smaller unit sizes, the electrical and control equip-
ment must be connected via the junction hood.
Connection cables for hand-held micro terminal, supply
air temperature sensor, air heater and air cooler have
modular connectors.
Other accessories and external functions can be con-
nected to an easy-to-access row of terminal connections.
All electrical and control equipment is collected inside a special
enclosure in the centred section of the air handling unit.
An extra terminal for a single phase 230 V supply is also
provided after the safety switch on the GOLD unit. This
terminal can be used for external functional sections and
can be loaded with max. 1.5 A.
The extra functional sections such as a cooling unit and
an electric air heater, must have a separate power supply.
GOLD RX/PX/CX
On the size 004-020 GOLD RX and the GOLD PX units,
electrical and control equipment must be wired via the
junction hood. On the size 025-070 and 080 GOLD RX
and the size 035-080 GOLD CX units, electrical and
control equipment must be wired via the panel on the
centre section of the air handling unit. On the size 080
GOLD RX, capacity variant 2, and the size 100/120 GOLD
CX units, electric power is connected across an external
safety switch and the electrical and control equipment
must be wired via the panel on the centre section of the
air handling unit.
GOLD SD
On the size 004-080 GOLD DS units, the electrical and
control equipment must be wired via the panel by the fan
inspection door. On the size 100/120 units, electric power
is connected across an external safety switch and the
electrical and control equipment must be wired via the
panel on the centre section of the air handling unit.
