WORKING INSTRUCTIONS
For security, the air curtains must always be stopped through the controller. Never stop
the air curtain disconnecting the main electricity supply.
We enclose wiring diagrams of air curtains with the corresponding controllers.
Connector plate characteristics:
(placed on top of the unit)
Relays and transformer
: It adjusts the fan speed through voltage variation by transformer so we have a
high and medium speed.
Controller’s common characteristics:
•
Two speed
air discharge.
•
Memory
: Guarantees that in the event of a power shortage, the selected speed will be maintained
when the service is re-established.
•
Telephone cable and digital communication
: “Plug and play” easy connection through telephone
cable and digital communication between the controller and the air curtain. Digital communication is
more reliable than analog, even at long distances.
•
External ON/OFF:
Inside the controller there is potential free contact (normally open) for remote
ON/OFF by any other external device. The most common uses are, for example, the connection with
programmable clock timer, room thermostats, door contact, DDC, fire alarms, etc…
