3490 Series Universal Controller General Overview

1. 3490 Series Universal Controller

2. 3490 Series Universal Controller General Overview

3490 Series Control Units provide I.S.
power for the transmitter and performs a
variety of calculations on the 4-20mA or
HART signal received from the
transmitter, providing
– A local display of information
– Performs many functions on the
input signal (translating level into
volume, flow etc.)
– A 4-20mA output proportional to the
calculated value

3. 3490 Series Universal Controller General Overview (continued)

– 5 programmable Relays for control
purposes (Set point, alarms etc.)
– Reads and programs common
commands on all HART transmitters
– Full programming to Rosemount
3100 Series Ultrasonic and 3300
Series GWR
– Three enclosure variants, IP rated
wall mount, NEMA 4X rated wall
mount and panel mount

5. Configuring the 3490 Series

The membrane keypad on the
front of the 3490 is used to field
configure the Controller.
– A simple menu system is used
to access the various features
that need to be configured
– The Controller has a set of
configuration Wizards which
appear to guide the user
through the menu.

12. 3493 Applications (Flow Logger)

Open channel flow with on-board data logging (7000 flow event,
typically 15 min logging interval = 75 days.)
Flow totalising and logging daily totals on-board. Daily totals
stored for last 365 days and rolls over oldest data.
Data retrieved by Log-View Software and can be used for report
generation
