Welcome Message from ChemDAQ

We hope that you are pleased with your ChemDAQ Steri-Trac®Gas Detection System. This Gas

Detection System has been designed and produced using state of the art facilities and we at ChemDAQ

are very proud of this product and expect it to provide you many years of reliable service.

The ChemDAQ gas monitoring system has been designed with simplicity of use as a basic design

principle. Once installed, the system requires no maintenance beyond periodic calibration of the sensors

and even this function has been simplified. The user will simply click out the old sensor and pop in the

new sensor; simpler than changing a light bulb. While the ChemDAQ system is designed to be simple to

use, it also contains all the advanced features that experienced users have come to expect in modern gas

detection instruments

While the Steri-Trac monitor can be used as a standalone instrument, the full benefit of the design is

only achieved when the monitor is integrated into a gas monitoring system. A full gas detection system

consists of one or more monitors connected to a ChemDAQ data acquisition system (DAQ). In addition,

there may be one or more remote displays connected to the monitors and remote video displays where

the results of the monitoring need to be observable at more than one location. The gas detection system

has been designed to be modular. This approach allows the product to be tailored to each customers

needs, and it provides for easy expansion as those needs change in the future.

Our focus at ChemDAQ is customer service and we want you to know that we will work with you to

solve any problems that may occur, though none are anticipated. We welcome praise about gas detection

products and customer service, but we especially want to know if any problems are experienced and of

course any suggestions for improvements to existing products or new products are most welcome.

OVERVIEW OF THE CHEMDAQ GAS MONITORING SYSTEM

The ChemDAQ Gas Monitoring System comprises several modular components, including a Steri-Trac

monitor, remote displays, DAQ data acquisition system, and remote video display. The Steri-Trac

monitor is designed to operate as a stand alone instrument, but it is also designed to serve as a part of an

integrated monitoring system. Up to eight Steri-Trac monitors can be connected to a central data

acquisition computer (DAQ), and each Steri-Trac monitor can support up to three remote displays. The

system has been designed to be fail safe, so that in the unlikely event that one component were to fail,

the rest of the system will continue to operate normally.

For example, the DAQ and all of the monitors are in constant two way communication. If this

communication is broken, then the DAQ will show a communication error, but the monitors will

continue to work normally.

Steri-Trac Area Monitor

The Steri-Trac area monitor is the key component of the ChemDAQ Gas Monitoring System. The

monitor is wall mounted and consists of three major components –the monitor body, the sensor module

and the wall box.

Steri-Trac Remote Display

If a monitor is in alarm indicating a gas leak, no-one should enter that area without adequate protective

equipment until the gas leak has been rectified. In order to avoid the situation where a person must enter

the hazardous location in order to read the display on the monitor, remote displays can be connected to

the monitor and placed outside the room or immediate location.

The remote display provides an immediate and convenient means for people to assess the danger from

outside a room before entering. Use of the remote display is very simple. The remote display is wall

mounted, connected by cable to the monitor and, in some cases, connected to a local power supply.

The remote display will duplicate the response of the monitor. Thus the remote display will show the

same display reading as the monitor, and it has an auditory horn that sounds at the same time as the area

monitor. The remote display horn can be silenced by pressing the alarm silence button on the remote

display but this does not silence the area monitor horn. Both the remote display and the area monitor

horns are silenced when the area monitor silence button is pressed.

ChemDAQ Data Acquisition System (DAQ)

Using proprietary ChemDAQ software, this PC-based module provides continuous, real-time display of

the current concentration levels for each area monitored, as well as the calculated 15-minute and 8-hour

time-weighted averages.

A unique feature exclusive to the ChemDAQ Sterilant Gas Monitoring Module is user adjustable

impending alarm settings. These alarms provide an early warning of escalating concentration levels

relative to OSHA requirements. All data is stored for subsequent recall, at any time, in report form. The

ChemDAQ Sterilant Gas Monitoring Module is fully compatible with signals sent continuously and

simultaneously from up to eight Area Monitors.

The ChemDAQ supplied PC, touch-screen monitor, and printer are preconfigured for operation with the

data acquisition software.

Up to eight Steri-Trac monitors can be connected to ChemDAQ’s proprietary data acquisition system

(DAQ). The monitors can also be configured through the DAQ computer. See discussion below and

DAQ manual for further information.

Remote Video Display

The image from the PC monitor can be mirrored on an optional ChemDAQ supplied remote video

display. This is beneficial for the employees working in areas such as Sterile Processing Wrap and Pack

because they can see the exact same thing as the SPD manager where they are working. Contact

ChemDAQ Inc. for additional information about the remote video display.

PARTS OF THE MONITOR

The Steri-Trac monitor comes in three parts: Monitor Body, Sensor Module and Wall Box

The Monitor Body is the heart of the instrument; it includes the visual display, auditory alarms and

signal processing circuitry. The Monitor Body Attaches to the Wall Box. The main body of the monitor

contains a large tri-color display that shows the real time gas reading. If the concentration of gas is

below a safe threshold, then the display shows the value in green. If the gas concentration is above a pre-

set Low Alarm level), but not yet at dangerous levels, then the display shows the real time concentration

in yellow and if the gas concentration exceeds concentration at which it is dangerous (High Alarm

level), then the display is red.

LED Display

Has four 1.2-inch high characters, each is a 5 X 7 dot array

Tri-color display –green for normal operation, yellow on low alarm and red on high alarm or

fault.

Updates every second to give real time ppm gas concentrations.

The monitor body also contains a loud alarm horn on the front face of the monitor body, that is activated

whenever the gas concentration exceeds the low alarm level. The alarm can be silenced by pressing the

alarm silence button, also located on the front of the monitor. The display continues to show the real-

time gas concentration (and alarm indication via display color and flash) even after the horn has been

silenced.

Horn

Simple beep indicates low alarm, continuous sound indicates high alarm

Horn can be silenced by pressing alarm silence button

The Sensor module contains an electrochemical gas sensor and for certain gases, ChemDAQ’s Spot-

On™ Filter that makes the sensor much more specific to the target gas which results fewer false alarms.

This proprietary filter removes common interferents which, for example, for ethylene oxide monitors are

alcohols and carbon monoxide.

The innovative patent-pending sensor module also contains the drive circuit for the sensor including an

on-board battery to eliminate warm-up times that are otherwise common with electrochemical sensors.

In addition, the sensor module contains an EEPROM memory that stores the sensor’s calibration and

configuration data. In order to ensure reliable calibration of the sensor, the sensor module is a

replaceable component and is periodically returned to ChemDAQ for replacement with a freshly

calibrated sensor module.

Remote Sensor Module

Typically, the sensor module is attached directly to the monitor. In certain cases, such as space or weight

constraints, the option to remotely mount the sensor becomes very valuable. The remote sensor module

can be used to position the sensor up to 100 feet from the monitor

The Wall Box

The wall box provides mechanical attachment of the Steri-Trac monitor to a wall. The wall box contains

connection points for AC power wiring, a power supply which converts the AC to 15VDC, the low

voltage electrical connections out to the remote displays, signal connections for the DAQ computers,

and dry relay contacts that respond to alarm conditions.

Cables are usually brought to the wall box via conduit from above, but the wall box is designed to

accommodate other orientations as well. Please see the Steri-Trac Installation Guide for a complete

description.

Relays in the Wall Box: The wall box contains dry relay contacts which open or close when the monitor

alarms. These contacts can be used to send a signal to a central alarm system or to activate other systems

such as exhaust fans.

There is a set of contacts for the low level alarm and a set for the high level alarm. The normally open

contacts are energized open when conditions are normal, and close during alarm conditions. The

normally closed contacts are energized closed when conditions are normal, and open during alarm

conditions.

The power supply in the wall box accepts either a 110 or 220 V AC supply at 50/60 Hz and provides

power to the instrument together with up to three remote displays.

Major Components of the Steri-Trac Monitor

Display and Horn

Display –Four digit ultra-bright 5x8 Tri-Color LED blocks that show the gas concentration in

parts per million (ppm). When the gas concentration is at safe levels (determined by user-defined

thresholds), the display is steady green. When the first user-defined alarm threshold is met the

display shows the real time gas concentration in orange to indicate the higher level or alert.

When the gas concentration exceeds the user-defined second alarm threshold the display turns to

red and flashes the real time gas concentration to alert all users of the dangerous situation.

Horn –The Steri-Trac includes an 85 dB horn that produces a loud cycling horn to notify users

that the gas concentration is above the first alarm threshold.

Alarm Silence Button Pressing the alarm silence button silences the alarm if the instrument is in alarm.

The default setting is that the alarm will stay silent so long as the gas concentration does not rise through
