In industrial environments, maintaining optimal ozone levels is crucial for safety and efficiency. The OS-6 ozone controller and monitor is designed to meet these demands with precision and reliability. Its robust construction, user-friendly interface, and advanced features make it an ideal choice for industries requiring stringent ozone control.

Key Features of the OS-6

The OS-6 is packed with features that ensure accuracy, ease of installation, setup, and operation:

• Industrial Strength Enclosure: The OS-6 is housed in a water-resistant polycarbonate enclosure (NEMA 4X), ensuring durability and protection against water spray and splash.
• Large Digital Display: The auto-ranging digital display (2-20 ppm) with backlight provides clear and immediate readings.
• Accessible Front Panel: Easy access to set points and relays on the front panel simplifies adjustments and maintenance.
• Adjustable Set Points: Precisely adjustable maximum, minimum, and fail time set points allow for customized control.
• Failure Alarm: An alarm is triggered if ozone levels remain outside the control range, ensuring immediate attention to potential issues.
• Generator Control Cutoff Switch: A front panel switch allows for easy maintenance without compromising safety.
• Selectable PPM Ranges: User-selectable PPM ranges for analog output (4-20 mA and 0-2 VDC) provide flexibility for different applications.
• OSHA Safety Limit Light: An indicator light warns if ozone levels exceed the OSHA safety limit of 0.1 ppm.

Specifications

The OS-6 boasts impressive specifications that enhance its functionality:

• Ozone Range: 0.03-20 ppm or 0-50 ppm with an electrochemical sensor.
• Enclosure Dimensions: H = 6.3”/160mm, W = 6.5”/166mm, D = 4.6”/118mm.
• Power Requirements: 12-24 VDC input, with +5 or +12-24 VDC output to the sensor.
• Data Communication: RS-232 serial data from remote sensor module (SM-4 or equivalent), with 9600 Baud 8N1 format.
• Analog Output: 0-2 V and 4-20 mA, with internal jumpers selecting the full-scale PPM range.
• Control Outputs: Relays capable of handling 10A @ 25VDC, 0.25A @ 250VDC, and 2.0 KVA AC (resistor).
• User Controls: Internal controls for MAX set point, MIN set point, FAIL time, increase, and decrease settings.
• Display and Indicators: Four-digit numeric display with backlight, and LED indicators for sensor status, above MAX, below MIN, >100 PPB, generator on, and failure.

OS-6 Sensor Components

The OS-6 system includes three main components:

1. OS-6 Base Unit: Contains relays, voltage outputs, and the digital display.
2. SM-7 Sensor Module: Houses the ozone sensor and measures ozone levels.
3. SM-EC Sensor Chip: A replaceable, pre-calibrated sensor chip that plugs into the SM-7 module.

These components work together to provide accurate ozone monitoring and control. The latest configuration with the SM-7 sensor module and SM-EC sensor chip supports a 0-50 ppm detection range, ideal for high-demand industrial applications.

Range Selection

The OS-6 is available with either a 0-20 ppm or 0-50 ppm sensor range. The standard configuration is 0-20 ppm, suitable for most industrial ozone control applications, including odor and food safety management. The SM-EC sensor chip, used in both configurations, offers high accuracy and reliability, even in environments with high humidity and volatile organic compounds (VOCs).

Remote Sensor Capabilities

The OS-6 comes with a standard cable length of about 6 feet, allowing flexible placement of the sensor module. For longer distances, up to 100 meters, shielded cable with at least 22 gauge wire is recommended. Testing has shown effective performance even at distances up to 1,000 feet using high-quality shielded cable.

Relay Operation and Indicators

The OS-6 includes three relays for control and alarm purposes:

• Safety Relay: Factory-set to 0.1 ppm to comply with OSHA standards, preventing tampering.
• Control Relay: User-settable to control ozone generators or trigger alarms.
• Alarm Relay: Set to trigger after a specified duration if ozone levels exceed the control relay’s threshold.

All settings are easily accessible via pushbuttons in the wiring compartment.

Calibration

Maintaining the accuracy of the OS-6 is straightforward. The SM-EC sensor chip should be replaced annually to ensure proper calibration. This cost-effective sensor chip is designed for easy replacement without the need for additional calibration adjustments.

Wireless Monitoring and Data Logging

Enhance the capabilities of the OS-6 with the Wireless Monitoring & Data Logging Kit. This kit allows remote access to the monitor via the internet, providing instant notifications through text and email alerts.

Conclusion

The OS-6 is a robust and reliable solution for industrial ozone monitoring and control. With its durable construction, advanced features, and ease of use, it meets the demanding requirements of various industrial applications. Whether for odor control, food safety, or general industrial ozone management, the OS-6 delivers precise and dependable performance.
