Recorder aids alarm analysis

A RTK Instruments product story
Edited by the Engineeringtalk editorial team Aug 18, 2005

The need to continuously monitor, record and analyse system performance is more important than ever, driven by the increasing regulations on safety and the high cost of plant shutdowns.

The need to continuously monitor, record and analyse system performance is more important than ever, driven by the increasing regulations on safety and the high cost of plant shutdowns.

The traditional backlit annunciator still provides the clearest method of alerting the operator and, when combined with RTK Instruments' System 9000TS, allows accurate time tagging of events.

The System 9000TS offers 1ms resolution of events and can be supplied as a stand-alone sequence of events recorder or, by using the optional integrated alarm annunciator features, it is possible to build a fully integrated alarm and event management system that captures and records the events for later analysis while providing displays and alarms for immediate action at the plant.

The modular construction of the System 9000TS uses standard 3U 19in Euroracks with rear access terminals.

The first rack provides up to 208 channels and houses the interface card and up to 13 sixteen-channel input/output cards.

Larger systems up to 4000 channels use additional racks interconnected by factory supplied ribbon cables.

Each input channel can be set to suit individual applications, for example: input time delay, alarm sequence, priority, grouping and channel description.

All facilities are field programmable using Windows-based software provided with the equipment.

All the alarm sequences specified in the ISA publication "Annunciator sequences and specifications" are available in addition to a wide range of additional features.

The system has a unique distributed method of storing events so that even following a cascade of alarms or a power failure, up to 15,000 events per rack are stored within the solid-state, nonvolatile memory.

The System 9000TS provides an independent, highly reliable, modular alarm system employing multiple redundant design features.
