PRINCIPAL FEATURES

The 5701 Series Control System is part of the System 57 family and is

designed to monitor field mounted industrial gas detectors.  The principal

features of the system are:

* Provides up to 16 channels of gas detection in a standard 19'' subrack using a 3U card format.

* Provides up to eight channels of gas detection in a half 19'' subrack using a 3U card format.

* Racking available for both front and rear access field wiring.

* Simple field connections for wire up to 2.5mm2

.

* Single channel mode of operation for high integrity systems.

* Channel Control Cards removable without disturbing other wiring.

* Catalytic bridge or 4 - 20mA input.

* Optional alarm change-over relay outputs.

* Multi-alarm mode for master, zoned and voted alarms.

* Rising, falling, STEL and LTEL / RATE alarm outputs.

* Update alarm on individual or multi channel alarms.

* Remote inhibit and reset inputs.

* Time delay on switch on and/or switch off of relay outputs.

* Optional 0 - 20mA or 4 - 20mA isolated monitor output.

* Easy to calibrate and operate using a dedicated Engineering card.

* EMC compliant.

* Options provided via Engineering Card:

* Master Alarm Update.

* Event Printers.

* Serial communication using Modbus protocol.

CHAPTER 1 - SYSTEM CONCEPT

MAN0443. P65 Issue 13 Aug 04 5701 Control System

05701-M-5001 A02279

2.  CONSTRUCTION

The system consists of individual 1'' (2.54cm) wide cards fitted to a

rigid custom rack designed to fit Euro rack cabinets.  Two rack widths

are available:

a. 19 inch with 17 card slots to house up to 16 Channel Control Cards

and an Engineering Card.

b. Half 19 inch with nine card slots to house up to eight Channel

Control Cards and an Engineering Card.

Each sub-rack contains an Engineering Card and a DC Input Card to

make up the rack system

The system is designed to meet the differing customer wiring

configurations and to achieve this the control functions are split away

from the relays and field wiring connections.  A single channel of gas

detection therefore consists of:

a. Sensor Drive Module

In order to achieve compatibility with a range of different inputs and

sensor types, the circuitry necessary to control the sensor is

housed on an independent plug-in Sensor Drive Module.  These

modules plug directly into a Channel Control Card and are factory

fitted.  There are two different modules, one for catalytic inputs and

one for 4 - 20mA inputs.

b. Single Channel Control Card

Each Single Channel Control Card functions independently and

contains all the necessary electronic circuitry to provide the sensor

drive, alarm detection and gas level display for that channel of gas

detection.

c. Field Interface or Relay Card

The Field Interface/Relay Cards provide the interface connections

between the Control Cards and their respective field connected

gas sensor.  In addition, Relay Cards provide alarm outputs to the

field connections
