5 - ELECTRICAL CONNECTIONS AND INITIAL SETUP

5.1 - Connect the device cables as shown on the labels facing the terminal board. The given symbols indicate what follows:

• (V+) - (V -) - supply’s terminals 11 - 30 Vdc

• (C1) - (N1) - normally closed alarm relay contact. The connection is valid when the detector is not in alarm state and JP2

jumper is in 2 - 3 position. If JP2 is positioned on 1-2 the contact results normally open. C1-N1 terminals are voltage free

• (C2) - (N2) - turbulence alarm normally closed contact relay. Connection is valid when the detector is not in an alarm state

and JP3 jumper is in 2 - 3 position.. If JP3 is positioned on 1-2 the contact results normally open. C2-N2 terminals are

voltage free

• (C3)-(N3) - normally closed fault relay contact.

Fault relay is normally powered (intrinsic safety).

Connection is valid when the detector is not in fault state and JP4 jumper is in 1 - 2 position.

If JP4 is in 2-3 position the contact is normally open.

C3-N3 terminals are voltage free.

• (SIG) - 0-5V analog output terminal. To use only during allignment.
