1. UK - Product information
1.1 In general
This additional guide describes the installation of Automatic Leakage Control (ALC), be-
tween the EXact2 main board and the Belimo modbus actuator (LS ALC damper motor
on extract air), and general operating conditions and reservations.
1.2 Application
ALC is a function that prevents leakage in units (AHU) with rotary heat exchangers. ALC
continuously measures and controls the pressure difference between supply airflow and
extract airflow to ensure that no contaminated air is recirculated to the clean air in the
air handling unit.
IMPORTANT!
ALC is configured in HMI at the factory. Only LS ALC dampers must be connected
to the EXact2 main board. See section 2. Connection.
1.3 Conditions
ALC can be configured and activated in applications with:
• Rotary heat exchanger
• Modbus-controlled damper in extract air.
• Pressure transmitter mounted between supply air and extract air in rotor section.
• Purging zone
• EXact2 Software version 3.11.1.0 or later.
1.4 Proviso:
ALC is cannot be used in applications controlled by:
• Constant motor speed / CO2 / RLQ / RH.
• For third-party control systems
1.5 Operating Mode
The principle of the ALC function is to keep a minimum negative pressure in the extract
air side (exhaust side) of the rotary heat exchanger in relation to the supply air side
(fresh air side) of 20 Pa.
If the differential pressure due to dynamic pressure changes moves towards a value
lower than 20 Pa, the extract air damper will gradually close towards the minimum to
maintain the positive differential pressure.
3006324-2021-12-14.fm UK - Product information
5/44
1.6 Operating conditions
• Maximum duct pressure drop on outdoor air: 100 Pa at maximum ERP airflow.
• Minimum duct pressure drop on extract air: 150 Pa at maximum ERP airflow.
• Maximum permitted imbalance in airflow between supply air and extract air:
50%.
NOTICE!
If the operating conditions are not met, there may be instability and/or leakage from ex-
tract air to supply air.
Stopping ALC
IMPORTANT! It is recommended that the system is switched off only during service
and maintenance, as leakage may occur during start-up.

2. Connection
2.1 Cable connection
Connect the Belimo Modbus actuator (LS ALC damper motor) to the EXact2 main
board. The Modbus damper motor on the ALC damper must be mounted on the extract
air spigot (see drawings in section 2.2).
The cable* from the damper motor must be mounted in accordance with the cable plan.
See section 'Cable plan' in the Electrical Installation Guide for EXact2 control system).
Mount the cable on the EXact2 main board on EXT. BUS – see photograph and table
below:
*If the modbus cable from the Belimo actuator cannot reach the EXact2 main board,
the cable must be extended in an IP54 plastic enclosure for outdoor installation. The
modbus actuator is not screened, so there is no need to screen the extension cable.

1. DK - Produkt information
1.1 Generelt
Denne tillægsvejledning beskriver montage af Automatisk Lækagekontrol (ALC), mel-
lem EXact2 main board og Belimo Modbus aktuatoren (LS ALC spjældmotoren på
fraluft) samt generelle driftsforhold og forbehold.
1.2 Anvendelse
ALC er en funktion, som forhindrer lækage i aggregater (AHU) med roterende varme-
veksler. ALC måler, kontrollerer og justerer kontinuerligt trykforskellen mellem tilluft- og
fraluftstrengen for at sikre, at der ikke recirkulerer forurenet luft til den rene luft i ventila-
tionsaggregatets tilluftstreng.
VIGTIGT!
ALC er konfigureret i HMI fra fabrik. Der skal kun tilsluttes LS ALC spjæld til EXact2
main board, se afsnit 2. Tilslutning.
1.3 Forudsætninger
ALC er muligt at konfigurere og aktivere i applikationer med:
• Roterende varmeveksler.
• Modbus styret spjæld i fraluft.
• Tryktransmitter monteret mellem tilluft og fraluft i rotorsektion.
• Renblæsningszone.
• EXact2 Software version 3.11.1.0 eller nyere.
1.4 Forbehold
ALC er ikke muligt i applikationer styret af:
• Konstant motorhastighed / CO2 / RLQ / RH.
• For anden automatik.
1.5 Drifts Funktion
Princippet i ALC funktionen er at holde et minimum undertryk i fraluftssiden (udsug-
ningssiden) af den roterende varmeveksler i forhold til tilluftssiden (Friskluftsiden) på 20
Pa.
Hvis differencetrykket på grund af dynamiske trykændringer bevæger sig imod en lave-
re værdi end 20 Pa, vil fraluftspjældet gradvist lukke imod minimum for at opretholde det
positive differencetryk.
3006324-2021-12-14.fm DK - Produkt information
10/44
1.6 Drifts forudsætninger
• Maksimal kanaltryktab (udeluft): 100 Pa ved maksimum ERP luftmængde.
• Minimum kanaltryktab (fraluft): 150Pa ved maksimum ERP luftmængde.
• Maksimal tilladelig ubalance i luftmængde mellem tilluft og fraluft: 50 %.
BEMÆRK!
Hvis driftsforudsætningerne ikke overholdes, kan der forkomme ustabilitet og/eller læ-
kage fra fraluft til tilluft.
Afbryd ALC
VIGTIGT! Det anbefales kun at slukke anlægget ved service og vedligeholdelse, da
der under opstart kortvarigt kan forekomme lækage.
