ABB SYMAP Digital Protection Relays Human Machine Interface

Human Machine Interface

SYMAP® is easy to program and operate. A large graphic LCD with optional LED indicators conveys

important data such as position of all connected breakers, parameter settings, and event histories

at a glance. Graphics and measurements are displayed side-by-side on the LCD, so that the user does

not have to switch between pages.

The entire programming of SYMAP® can be

done with the keys on its front panel or by

using a notebook. Using a notebook offers

the advantage that stored parameters can

easily be applied to other SYMAP® units.

Either way, easy programming is guaranteed

and on-site visits by the manufacturer’s engi

neers during commissioning is not required.

SYMAP® provides four hotkeys placed under

neath the LCD to access four main groups of

values, namely »Meters«, »Alarm«, »Process«

and »Breaker Control«. The user can press the

hotkeys to scroll through pages of information.

The hotkey »Meters« provides detailed infor

mation on electric measurement values,

counters for active and reactive power and working hours. 

The hotkey »Alarm« displays

all active alarms, event log and blockings. »Process« shows all process data such as the synchro

nization display, motor thermal indication and a counter of breaker operations. Under »Breaker

Control«, up to five breakers can be accessed and controlled.

When programming breaker controls the user has access to various layout configurations via a

library. Programmed blockings remain active when manual control of the breaker is used. Each of

the highlighted breakers in the LCD can be further controlled by the keys »O« and »I«.

For security, access to SYMAP®’s parameter and breaker control data is protected by a code system,

accessed by a password.
