7.1 Local HART connection

7.1.1 As a Varec tank gauging instrument

The 4532 ATC has been developed and designated primarily to work with the Varec tank

gauging host instruments 4590 TSM or 6000 Series Servo Tank Gauge.

Temperature information is transmitted on a two wire i.s HART loop to the host

instrument.

Since both the 4590 TSM and 6000 Series Servo Tank Gauge have a pre-configured

menu for 453x average temperature devices functionality as default, simple wiring to

the 4532 ATC will complete the initial setup for the 4532 ATC.

7.1.2 As a standalone generic HART instrument

The 4532 ATC is a HART foundation registered intrinsically safe loop powered device.

The 4532 ATC provides four basic types of data as standard and parameter information

via HART protocol, command 3. Configuration to host communication can be performed

by a HC (Hand Communicator) or the Varec ToF field service tool to set a specific HART

address.

20: Measurement function

• 0: Converter only

• 1: Temperature + converter

These four basic data are available as standard.

• Average liquid temperature

• Average gas phase temperature

• Level (entered liquid level at "VH02 measured distance")

• Device status

7.2 Device set up: 4590 TSM

Connect the loop powered HART communication cable from the 4590 TSM (intrinsically

safe side compartment) to the 4532 ATC.

Since the 4590 TSM has been designed to recognize the 4532 ATC as a specific Varec

HART instrument, set up is easy.

7.2.1 HART scanner

After the physical cabling between the 4532 ATC and the 4590 TSM is complete, scan

all connected loop powered HART devices by activating "HART SCAN" on the version 1.x

4590 TSM. The version 2.x 4590 TSM continually scans the HART bus and will

automatically detect the 4532 ATC when it is connected.

Caution! Not all 4590 TSM have fully accessible compatibility to recognize the 4532 ATC.

Consult with your Varec representative to cross check the software and hardware

version of the 4590 TSM.
