1 Remote Display System
1.1 Overview
This document describes the basic configuration of the VEGA devices connected
to the Remote Display System. The configurations described are necessary for
the accuracy and proper operation of the Remote Display System level
monitoring, system alarms, and displays.
1.2 System Operation
The VEGA level measurement device, in combination with the RD, provide the
level information to the Remote Display. Each RD can handle one (1) VEGA, 2-
wire HART device. The Remote Display interface can display level, percent (%),
scaled value, and distance. The following requirements are necessary for the
proper operation:
•
You must attach devices to the RD with the field devices set for HART
Multidrop mode.
•
Each device connected to the RD must have a HART address in the
range of 1.
•
The RD communicates with the VEGA PLICSCOM using I
2
C
communication.
1.3 System Features
The RD system has the following features:
•
Power options via battery.
•
Numeric visualization: Scaled measured values display on the backlit
LCD screen.
•
Connect to any VEGA two-wire HART multidrop device.
Note:
Do not use the device in the standard 4 ... 20 mA mode.
Using the device in this mode drains the batteries.
