Chapter 1 Introduction

Introduction

The Uni-Tranmicro-controllerbased toxic gas detector provides fast, accurate, continuous and cost effective

monitoring of toxic gases in harsh industrial environments.

Net Safety selects the very best electrochemical sensors from the world's leading manufacturers for use in its broad line of toxic gas detectors. High performance, proprietary circuits and micro-controllerbased firmware ensure accurate and repeatable response in the most severe environments and a reduced need for routine calibrations.

The Uni-Trancontrol module uses advancedmicro-controllertechnology to provide a user interface that is comprehensive, yet very simple to use. The full text LED display gives the user complete instructions for routine operation, calibration and relay configuration; without tools.

Features

<Electrochemical sensor technology

<Low power consumption that works with 12 or 24 Vdc systems

<Easy, non-intrusiveone person calibration

<Sensor can be remotely mounted up to 75 feet from the display module

<Scrolling alpha-numericLED display available in English, French or Spanish

<Gas specific colour coded enclosure

<Microprocessor based smart transmitter

<Conformal coated circuit boards

Chapter 2 Installation and Start Up

What’s in the package

Carefully remove all the components from the packing box(s). Check components against the packing list. Inspect all components for obvious damage and broken/loose parts. Notify the carrier and distributor immediately if damage is found or parts are missing.

Location of Sensor(s)

There are no absolute rules for determining the quantity and location of gas detection instruments within a particular facility. Care should be taken to locate the sensors in areas where gas escape may be expected and where it is desirable to detect the presence of unwanted gas. Use redundancy where enhanced protection or reliability is desired. Heavy gases such as H2S, CO and SO2 tend to accumulate in low areas. Seek advice from experts who know the characteristics of the gas being detected, air movement patterns and the facility. Use common sense and refer to various publications that discuss general guidelines for your industry.

Unpacking

The UNI-TRANPremium Plus is made up of two primary components (refer to figure 1). The Enclosure and relay board are a single assembly to which the sensor is wired. The control module (CPU board / display board) is a separateplug-inassembly. First, remove the sensor from the white shipping container (not applicable to ST1210) Remove the lower half of the Sensor Housing by unscrewing it counter clockwise. Plug the sensor into the upper half of the Sensor Housing. Replace the lower Sensor Housing and tighten the housing.

WARNING:

Do not attempt to unscrew the “knurled” pull knob. Do not separate the CPU board and Display board.

NOTE:

Since all modern electronic equipment can be damaged by static electricity discharge, it is important to take precautions. Discharge static electricity from your body by touching a grounded metal object before handling the module.

Remove the control module from the housing, by grasping the centre “pull” knob and pulling straight away, then temporarily store the control module in a clean safe place until after the field wiring has been connected to the terminal strip located on the relay board.

Mounting

The housing should be oriented so that the sensor is on the underside of the housing. Water will damage electronic devices. Seal conduit near housing entries to prevent water damage in the enclosure (refer to figure 2, 3, 4 and 5).
