Tilslutninger
Connections
Nødvendige tilslutninger
Klemme:
25-26 Forsyningsspænding 24 V a.c.
21-24 Spænding til stepmotor
18-19 Pt 1000 føler ved fordamperafgang (S2)
14-15 Tryktransmitter type AKS 33
1-2 Kontaktfunktion til start/stop af reguleringen. Hvis der
ikke tilsluttes en kontakt, skal klemme 1 og 2 kortsluttes.
5-6 Batteri (spændingen vil lukke ETS-ventilen, hvis regula-
toren mister forsyningsspændingen. Batteri-tilslutningen
kan dog erstattes med installation af en magnetventil i
væskeledningen. Denne tilsluttes så klemme 8-9.
VIGTIGT
24 Volts a.c. forsyningen til EKC 316A på klemme 25 og
26 skal holdes helt adskilt fra forsyningen til batteriet på
klemme 5 og 6, og disse to forsyninger må under ingen
omstændigheder have en fælles jordforbindelse.
Applicationbestemte tilslutninger
Klemme:
18-20 Pt 1000 føler til måling af lufttemperatur (S3)
8-9 Termostatrelæ
12-13 Alarmrelæet
Der er forbindelse imellem 12 og 13 i alarmsituationer, og
når regulatoren er spændingsløs
16-17 Strømsignal fra anden regulering (Ext.Ref.)
3-4 Datakommunikation
Monteres kun, hvis der også er monteret et datakommuni-
kationsmodul.
Det er vigtigt, at installationen af datakommunikations-
kablet udføres korrekt.

Necessary connections
Terminals:
25-26 Supply voltage 24 V a.c.
21-24 Supply to step motor
18-19 Pt 1000 sensor at evaporator outlet (S2)
14-15 Pressure transmitter type AKS 33
1-2 Switch function for start/stop of regulation. If a switch
is not connected, terminals 1 and 2 must be
short circuited.
5-6 Battery (the voltage will close the ETS valve if the control-
ler loses its supply voltage. The battery connection may
however be replaced by installation of a solenoid valve
in the liquid line. This will then be connected to terminals
8-9.
IMPORTANT
The 24 Volts a.c. supply to the EKC 316A at terminals 25
and 26 should be completely isolated from the battery
supply at terminals 5 and 6, and under no circumstances
should these two supplies have common earth.
Application dependent connections
Terminal:
18-20 Pt 1000 sensor for measuring air temperature (S3)
8-9 Thermostat relay
12-13 Alarm relay
There is connection between 12 and 13 in alarm situa tions
and when the controller is dead
16-17 Current signal from other regulation (Ext.Ref.)
3-4 Data communication
Mount only, if a data communication module has been
mounted.
It is important that the installation of the data communi-
cation cable be done correctly. Cf. separate literature No.
