! WARNINGS:

General Precautions

1. Ozone (O3) is a toxic gas. High concentrations of ozone are dangerous and harmful to

humans. Take reasonable steps to avoid exposure. The current maximum 8-hour exposure

limit for ozone is 0.1 PPM (according to U.S. OSHA).

2. Install appropriate safety monitoring equipment wherever high concentrations of ozone are

used. IN USA, INC. manufactures several ozone monitors for workplace safety applications.

3. Materials in contact with high concentrations of ozone should be suitable for such use.

316L Stainless, Teflon™, Chemraz™ and Kynar™ are recommended.

4. When performing any maintenance to the SCI-Mux Controller, make sure all AC power is

disconnected from the unit.

5. The gFFOZ ozone sensor contains an ultraviolet (UV) lamp. Never remove the lamp from its

housing while the unit is powered on. Proper eye protection is required—eye exposure to UV

light is extremely dangerous.

6. Certain components may be hot to the touch. Please allow proper cooling time before

working with these components.

7. Never attempt to open ozone catalyst canisters (if supplied). The content of the canisters can

be hazardous if not handled properly.

8. Use only IN USA, INC. recommended spare parts. Substitution parts could result in damage

to the equipment, may create hazardous conditions and will void the warranty.

9. Use this equipment as recommended in this manual. Use of the equipment in ways other

than specified by IN USA may create hazardous conditions.

CAUTIONS

1. Read this operating manual before operating the SCI-Mux Controller.

2. Do not subject the SCI-Mux to extreme physical or thermal shock.

3. Use care in handling the SCI-Mux and any of its components.

labeled “INTERLOCK”. If the Interlock is OPEN, the generators will not power up. To

CLOSE the Interlock, plug the mating connector into the INTERLOCK connector (if it is

not already plugged in).

1.3 Initial Power-On

To turn the SCI-Mux Controller on, press the POWER switch on the rear panel. The switch

illuminates (red) when the power is ON. The SCI-Mux powers up and goes through a four-

step start-up procedure.

example:

INUSA H2 SW Vx.xxx

PLEASE WAIT

2. The SCI-Mux displays the ozone sensor type for each of the four channels

approximately 5 seconds. For example, TYPE 1 refers to a gFFOZ ozone sensor. Type

2 refers to a dFFOZ ozone sensor. If a sensor is not installed for a channel, “NO SEN”

is displayed. For example:

1 0



Page 5 of 55

3. The Sci-Mux displays the warm-up screen. The display shows “*****" (a series of

asterisks) for the readout associated to a channel with an ozone sensor connected to it,

indicating that a warm-up period (approx. 3 minutes) is in progress. A series of dashes

is displayed if no sensor is connected. For example:

A: ***** G/M3 B: ***** %WT

C: ***** MG/L D: ------

4. As the Warm-up time expires, the Sci-Mux Controller displays the Ozone

Concentration screen. Channels with no sensor connected will continue to show a

series of dashes (e.g., Channel D).

2. Features and Capabilities

2.1 Overview

The IN USA, Inc. Model SCI-Mux™ is a rack-mounted or bench top, four-channel ozone

measurement and ozone delivery control system. It supports digital serial communications via

a bi-directional RS232 link.. It can also be operated manually through the keyboard located in

the front panel.

2.2 Ozone Delivery System Components

The Sci-Mux Controller directly interfaces with the following ozone delivery system

components:

• Tool Host Computer

• 4 IN USA, Inc. Ozone Sensors - ( for example model gFFOZ or model dFFOZ )

• 4 Ozone Generators

• Peripherals, through electromechanical relays, 2 per channel, total of 8, Form C

2.3 Ozone Sensor Interface

Please refer to the appropriate IN USA, Inc. Manual for detailed information on the specific

Ozone Sensor Model.

The sensors measure ozone via light absorption method, and incorporate IN USA’s patented

dual optical-path sensing technology to provide superior performance and virtually eliminate

the need for a reference measurement.

The Sci-Mux Controller processes the sensors output signals to compute a highly-accurate

measurement of ozone concentration. The concentration measurement from the ozone sensor

is also used by the Sci-Mux servo algorithm to control ozone generator output.

2.4 Host Computer Interface

The Sci-Mux Controller interfaces directly to the tool host computer via an RS232

communications link. Commands sent from the host to the Sci-Mux determine the state and

the setpoint of the remote components of the ozone delivery system. In turn, analog and

digital signals indicating the state and current reading of the components are returned to the

host computer.

2.5 Ozone Delivery System Interface

The Sci-Mux Controller interfaces the remote components of the ozone delivery system via

analog and digital inputs and outputs. In general, these signals are employed as follows:



Page 2 of 55

• Analog Output (AO) to a component to establish a setpoint.

• Analog Input (AI) from a component to obtain a current reading.

• Digital Output (DO) to a component to establish a state.

• Digital Input (DI) from a component to determine a current state.

Additional details on the interface with each component of the ozone delivery system are in

Section 0.

2.6 RS232 Communications

The Sci-Mux Controller interfaces directly to the tool host computer via an RS232 bi-

directional serial interface. A variety of high level commands are available to establish states

and setpoints for the remote components and upload data to the host.

The following commands are available for communication between the Model Sci-Mux and

the tool host:

• Upload Data

• Request Status

• Zero Ozone Sensor

• Generator Power Setpoint

• Generator Enable/Disable

• Servo Parameters

• Servo Setpoint & Enable/Disable

Refer to Section 0 for additional information on the RS232 command set.

2.7 Ozone Generator Servo Control (Factory Fitted Option)

The Sci-Mux Controller uses a closed-loop servo to control up to 4 ozone generators and

thereby deliver a stable ozone concentration to up to 4 processes. The servo control system is

composed of an ozone sensor, the ozone generator, hardware in the Sci-Mux Controller, and a

proprietary control algorithm running on the Sci-Mux microprocessor.

LATCHED or UNLATCHED. The default is Latched.

An unlatched alarm will only remain active while the given alarm condition that

triggered it is present. A latched alarm will remain active until it is reset. Resetting a

Latched alarm is accomplished by actuating the "E" key, located on the Front Panel.

Of course, pressing the "E" Key will only clear a latched alarm if the original alarm

condition is no longer present.

4.4.2.4 OZONE UNITS OF MEASUREMENT

For each channel, there are different units of measurement of ozone concentration. For

channels connected to a gFFOZ gas phase sensor, the units available are:

G/M3 (gram of Ozone per cubic meter of mixture at the temperature and pressure of the

gas in the gFFOZ sensor);

G/NM3 (gram of Ozone per Normal cubic meter; i.e.: 0 °C and 1 atmosphere); and

% WEIGHT (ratio in percent of mass of ozone to mass of mixture).

For channels connected to a dFFOZ dissolved ozone in water sensor, the unit available

is MG/L (milligram of Ozone per liter Water).

Note that 1 MG/L = 1 Part Per Million by Weight (PPMW).

press the scroll key to view them sequentially. Press any key to get back to the 'OZONE Screen'.

Viewing Status via RS232

To view error messages from the RS232 interface, issue the 'S' command. Upon receipt of this

request, the unit will respond with a message as follows:

k2 is the sensor type (e.g. 0,1),

k3 is power control ON/OFF (0,1),

k4 is concentration control ON/OFF (0,1),

k5 is the zeroing ID and is displayed only while zeroing, and

k6,k7.... are error/alarm ID's and are displayed only when error or alarm conditions are

active.

4.5 RS232 Communications

The SCI-Mux Controller interfaces directly to the host computer via an RS232 serial

interface. A variety of high-level commands are available to establish states and setpoints for

the remote components and upload information to the host. The RS232 command set is
