IK-765SS-O3 Panel Features
The IK-765SS-O3 is a dual-parameter inline water analyzer specifically designed as a
‘Turn-Key’ monitoring solution for clean water applications including bottled water
production, drinking water networks, secondary water supply and alternative clean-
water ozone treatment applications. The IK-765SS-O3 offers highly accurate, real-
time measurement, display and data-logging of Ozone (O3), pH and Temperature
utilizing proprietary Pyxis Lab smart sensor technology, coupled with a Pyxis UC-80
touch screen display and data logging terminal. The IK-765 series is offered in a
convenient and easy to integrate panel mounted format for rapid installation and
simple maintenance.
Features
•Pyxis Lab’s advanced research and development sensor technologies to achieve highly accurate and stable measurement of
Ozone, pH, and Temperature.
•Pyxis ST-765SS-O3 is a three-parameter composite sensor used for the measurement residual ozone, pH, and temperature in
compliance with USEPA 334.0 and ISO-7393 guidelines. The sensors advanced PCB offer built-in temperature and pH parameter
compensation (up to pH 9.0+) algorithms eliminating the need for a supplemental pH sensor and controller. Unique Bare-Gold
electrode technology for ozone measurement eliminates membranes and electrode solution replenishment commonly
associated with conventional sensors. The ST-765SS Series has a uniquely designed flat bubble pH electrode design for reduced
fouling potential. Reduce your maintenance and cost versus conventional electrochemical sensors by utilizing Pyxis replaceable
Electrode Head (EH-765) for this sensor allowing for years of reliable service. The ST-765SS Series may be calibrated in-situ after
cleaning via DPD or similar Ozone wet chemistry test measurement of active sample.
•Pyxis ST-007 Single-Sensor inline stainless steel flow cell provides an ozone demand-free environment for the safe
installation and accurate operation of the ST-765SS-O3 sensor. The inlet and outlet to the ST-007 are 316L stainless steel
with SwageLok fittings in ¼-inch OD. The IK-765SS-O3 panel is also equipped with inlet PRV, Rotameter and digital Hall Effect
inlet flow meter for precise control and recording of the recommended flow range of 200-400 mL/minute. The outlet flow should
be diverted to drain or the inlet of the pretreatment system for those desiring NSF compliance.
•Simple sensor removal and replacement. The ST-765SS Series sensors are connected to the display/data logger via RS-485
Modbus (RTU) allowing for integrated sensor calibration interface and diagnostics within the display screen.
•Convenient and simple to install Back-Panel (IK-765) for rapid and easy installation. Truly a plumb and power to go
platform with intense factory setup, testing and sensor calibration prior to shipment.
•UC-80 touch screen color display/data logger prewired to the Pyxis sensor via RS-485 with calibration interface. Display/data
logger offers 2x 4-20mA, RS-485 and TCP Modbus output with remote diagnosis and parameter adjustment. Pyxis
PowerCloudTM 4G Gateway available as an optional accessory.

3.3. Terminal Wiring
The IK-765SS-O3 analyzer has universal AC power supply equipment allowing users simply to plug the power supply
into a 100~240V AC 50/60Hz power outlet for normal operation.
Warning
The process of electrical connection to contact the 220V single-phase power supply, should be operated by personnel with an
electrician's license. Failure to operate according to the electrical code of practice may result in electric shock injury or even death.

4.3. Real-Time Monitoring
Click the "Enter System" button on the main interface to enter the real-time monitoring screen of the system. The data
detected by the Pyxis sensors will be displayed in real-time. See a functional overview of each section of this screen
highlighted below. (numbers 1-4)

4.4. Explanation and use of the HOLD Feature
Within the ADMIN USER ENTRY level, the IK-765SS-O3 has an integrated HOLD feature for all Modbus TCP output
parameters from the sensor that would be connected to an onsite DCS network. The purpose for this feature is to
allow the user to enter a signal value HOLD on the designated parameter during periods of sensor maintenance or
removal. This feature prevents network system alarms from operational shutdown during sensor maintenance or
replacement. Please refer to the Administration Instruction Guide for IK-765SS-O3 for login details to ADMIN level.
Click the "Hold OFF" button on the main interface to enter the HOLD setting interface.
Figure. 7 - Main interface
In the pop-up box, enter the parameter value and click "Confirm" to open the "Hold ON" function. The main interface
will display the entered value for 15 minutes, after which it will resume displaying the real-time value read by the
sensor.
When the "Hold ON" function is activated by the user, the sensor may be maintained, calibrated, or removed and the
Modbus TCP output will continue to retain the user entered value for a period of 15 minutes, ensuring network alarm
and process will not be interrupted due to the sudden disappearance of the ‘normal’ value. The ‘actual’ live sensor
reading along with the user entered hold value reading will both be displayed during this period.
Clicking "Cancel" will turn off this function, the main interface will immediately display the real-time value read by the
sensor, and the main interface button will be displayed as "Hold OFF".
