MSA DESCRIPTION

2. Description

General overview

2.1.

Fig. 1 GasGard XL

The control system is a wall mounted version of a permanent gas warning device. It is used to monitor industrial premises and installations for the presence of combustible, explosive, toxic gases or air/vapour mixtures and oxygen content.

The control system provides power to the sensors, signal conditioning and display of measured gas concentrations, alarm thresholds, outputs for alarm devices and self-monitoring diagnostics.

Recommended operational lifetime according to EN 50271 is 20 years.

The unit consist of up to 8 channels for monitoring active or passive sensors.

It can be used for:

 EX-monitoring for protecting operational plants and individuals working there

by continuously monitoring the atmospheres for potentially explosive gases/vapours in air before they reach the lower explosion limit – activating alarms and initiating risk aversion measures.

 It is approved in accordance with Directive 2014/34/EU [ATEX].  OX-monitoring for protecting individuals by continuously monitoring the

atmosphere for oxygen deficiency or oxygen enrichment or monitoring the inerting of operational plants.

 It is approved in accordance with Directive 2014/34/EU [ATEX].  TOX-monitoring for protecting individuals by continuously monitoring the

atmosphere toxic gas concentrations.

MSA INSTALLATION

Electrical Installation

3.2.

Attention!

The control system must be installed only in compliance with the applicable regulations, otherwise the safe operation of the instrument is not guaranteed.

During installation, use the internal earth connection to ground the instruments.

If an external earth connection is permitted or demanded by the local authorities, it serves merely as additional earthing.

The installation location shall be selected such that the environmental conditions indicated in the technical data can be met.

When installing the Control Unit the following conditions must be met to comply with the EMC Directive

 To connect devices to the main power supply, a fault-free ground or fault-free

potential bonding conductor must be provided.

 The user must ensure an appropriate supply voltage in accordance with EMC

directives.

 All sensor and control cables must be shielded.  Shielded cables must have at least 80 % coverage.  Control and sensor cables must be installed physically separate from power

supply cables.

 Shielded cables must be laid in a group. If cable lengths are to be extended

using terminal boxes, the boxes must be shielded and the internal connections must be kept as short as possible.

Warning!

When opening the instrument's housing care must be taken of high voltage danger from relay contacts and main power supply.

Only authorized person should be authorized to open the instrument. The AC mains source shall not be subjected to voltage variations exceeding the limits as specified in this Manual.

The AC mains source shall be free of any surges and sudden voltage changes due to heavy electrical loads and disturbances as caused by inductive or capacitive loads, false contacts and strong electromagnetic interference.

Do not penetrate the housing of the power supply with screw drivers or small parts. Care must be taken with screws falling into the power supply!

GasGard XL Wall Mount Controller

INSTALLATION MSA

3.2.1. Power Supply

Standard power supply 100 to 255 VAC, 50/60 Hz, 24 VDC ±20 % is used to power internal circuits up.

Two options to power up the Gasgard XL are available by MSA:

1. Mains supply 100 to 255 VAC only

2. Mains supply 100 to 255 VAC and 24 VDC internal backup battery

Main voltage is connected to terminal L (Line), N (Neutral), and ground.

Fig. 8 Connecting Main Supply

3.2.2. Sensor connection

Sensor must be connected to the terminals on the main board or sensor extension board (for details  Appendix C and Appendix D).

Attention!

Follow the instructions for components subject to damage from static electricity!

Incorrect connection of the sensors shall not damage both of Control Unit or sensor.

The wiring diagrams for different sensors are shown in Appendix B. The sensors must be connected to the terminals using shielded cables.

For the maximum cable length of sensors refer to the technical specification.
