The OS-6 is an industrial grade ozone controller and monitor. The OS-6 design has
been optimized for accuracy, ease of
installation, setup and operation.
 Easily accessible connection
terminals and controls allow the
unit to be setup after it is
mounted.
 Rugged,
splash
enclosure and connectors for
industrial environments.
 Front panel digital LCD displays
ozone level.
 Indicators display when ozone
exceeds the 0.1ppm OSHA limit
and a variety of other important
ozone control parameters.
 Set points for ozone control relays are digitally controlled with numeric set points.
This makes precise ozone control easy to set up, even if ozone is not present.
 "Monitor Mode" can be enabled at the OS-6 panel. This mode disables the ozone
generator controller and failure mode status indicators while maintaining ozone
measurement and limit warning indicators.
 User selectable PPM ranges for analog output (4-20 mA and 0-2 VDC)
 Ozone generator failure detection option warns when the connected ozone
generator is not maintaining the desired ozone set points. This option is disabled
when the instrument is in Monitor Mode.

  • Page 1 This makes precise ozone control easy to set up, even if ozone is not present.  “Monitor Mode” can be enabled at the OS-6 panel. This mode disables the ozone generator controller and failure mode status indicators while maintaining ozone measurement and limit warning indicators.
  • Page 2 0.1 PPM (OSHA 8hr time-weighted average safety limit). A relay (TB5) engages with this indicator to provide remote alarm capability.  Generator Control: Illuminates when the ozone generator relay is engaged, indicating the ozone generator is on.

    6’ 3-wire cable connected to TB1 +5V, BLK (grd) and WHT (data). AC Adapter For 120 V, 60 HZ areas, the Eco Sensors P-20 adapter should be used. For all other areas, adapters should be purchased locally that fit local wall sockets and conform to local codes.

  • Page 5: Data Connection

    Data Connection The serial digital data stream from the SM-4 is available for connection to a computer via the OS-6. Data is sent at 1-second intervals. The parameters serial communication parameters are: 9600 bps, 8 data bits, Parity: None, Stop bits: 1, Flow Control: None.

    0.000 to 999.9 PPM, to accommodate a range of currently available and future sensor modules.  The range of an OS-6 is limited by the sensor module. The OS-6 is shipped from the factory with the Full Scale Range set to match the installed sensor module.

    Therefore it is more cost effective to replace the SM-X board than to request that it be recalibrated.  Always remove power from OS-6 and SM-4 before connecting SM-4 to OS-6, or replacing SM-X. Follow Diagram in Appendix A to connect power and SM-4 to OS-6.
  • Page 8 Appendix A: Wiring Illustration – SM-4 to OS-6 (OS-6 Rev 4.0): CAUTION: TB1 is to be used to connect signal, ground and 5V power from OS-6.If using 12-24V to power SM-4 module, connect power (V+) to TB2. DO NOT connect 12- 24 V to TB1, this will damage the SM-4 and void warranty.
