Installing the Display Unit and its shield
1. Choose an easily accessible location, and mount the shield on the wall with three screws.
2. Watch the distance between Display Unit and sensor – the length of the connection cable is
10m (33 ft).
3. Fasten the Display Unit to the shield with three screws. First hang the unit to the topmost
screw, and then attach the screws in the lower corners.

Connecting a Communicator-i to Display Unit
Electric connections
NOTE: Before connecting the mains
power wires, make sure that the wires
are not powered!
1. Insert the Display Unit cable to the
Field Connection Board through
the cable inlet bushings. Connect
the wires as shown on the right.
2. Connect the necessary current sig-
nal cables to the analog outputs.
Consistency signal – connect ei-
ther to the Display Unit or to the
sensor’s Field Connection Board
(not both).
3. Connect the alarm output (open-
ing contact: terminals 17 & 18,
closing contact: 18 & 19).
4. Ground the cable between sensor
and Display Unit by connecting
the cable shield to the sensor elec-
tronics’ ground bar. Ground the
current output and alarm output
cables at only one end (not both).
5. Connect operating voltage (90...
260V) to the terminal on the left
side of Display Unit.
6. Connect a Communicator-i or
HART communicator (if used)
to the unit.
