Page 9: St-007 Installation & Operation For Clean Water Only
Application Use: The ST-007 is a unique 316L stainless steel inline tee assembly specifically designed to safely house Pyxis inline sensors used in clean water applications only. The ST-007 should never be used in industrial or dirty water applications subject to suspended solids or particulate matter. The ST-007 is sold separately. -

4-20mA output signal, they are NOT LOOP POWERED. 24VDC+ power supply and 4- 20mA+ signal are independent of each other in all Pyxis Lab sensors. If the 24V power ground and the 4-20 mA-return in the controller are internally connected (non- isolated 4-20mA input), it is unnecessary to connect the 4-20 mA- (Gray wire) to the 4-20 mA negative terminal in the controller. - Page 15 FR-300-PLUS Wiring Instructions Follow the wiring table below to connect the FR-300-PLUS to a controller or the Pyxis UC-50 via 24VDC and RS- 485 modbus. Alternatively, any OEM controllers capable of providing 24VDC power supply may also be used. The FR-300-PLUS may be operated 100% of the time with no issue, simply by providing the unit 24VDC power supply.

Page 16: Calibration And Diagnosis
6. Calibration and Diagnosis The ST-765SS Series sensors are rigorously calibrated before leaving the factory. As such, users do not need to calibrate the sensor for a period of three months or up to one year if the sensor is maintained in clean condition. - Page 17 Tap the discovered ST-765SS sensor to connect to the sensor. The uPyxis app can identify the sensor type if multiple Pyxis sensors are discovered in the scan. As shown in Figure 6, in the calibration page of uPyxis after connected to the sensor via the MA-CR Bluetooth adapter the current Free Chlorine, Sulfite, pH and temperature values will be displayed.
