2.6 OXYvisor Analyzer Features (Hardware/Firmware/Software)

HMI Touch Keys (thru-the-glass): Easy to use configuration and calibration menus can be accessed through
a touch screen, infrared keypad, protected behind the analyzer window.
HMI LockOut Screen: HMI lockout screen prevents any unwanted HMI interaction with critters, debris, or
working technicians.
Sensor Connection Junction Box: Connection of the BOS Optical Sensor is easily and quickly made
through the junction box. In the rare case it is ever needed, this design allows for easy fiber optic sensor
replacement, in the field, without exposing the electronics to dust, humidity or human error. Normally the fiber
optic is installed once and the sensor cap is the standard replacement.
On-board Data-logging: A USB port within the rear compartment, can be used for downloading device
specific configuration files, logs of measurement data, and diagnostic information. Historical time based
Oxygen, phase angle, intensity, temperature and pressure measurement, along with error logs and calibration
history is stored via .csv and available for download via USB memory stick.
Programmable I / O: The OXYvisor comes standard with two analog outputs, four isolated digital relay
outputs, one analog input. All I / O's are fully user configurable (variable and range) through the keypad,
software or RS485 Modbus. Additionally, a digital input (active) can be used to connect a customer supplied
toggle switch or other external contact, to initiate AutoCal or test gas insert (REMOTE VALIDATION).
Calibration Options: Several calibration options are available to best suit the customers installation and
application requirements.
• Factory Cal provides quick startup without test gas. The calibration values found on the sensor certification
sheet can be uploaded and good results can be expected. (We recommend to validate with test gas.)
• Manual One-point calibration with either zero or span gas, depending on the customer requirements.
• Manual Two-point calibration using zero and span gas (recommended for new users).
• Auto-calibration (AutoCal) logic in the OXYvisor firmware along with three on-board digital relays (passive)
allows for complete AutoCal and validation with know test gases. The AutoCal logic allows user
programming of timed based calibration, gas selection and the hysteresis criteria for pass / fail evaluation.
Requires: AutoCal SCP Panel (SCP Data Sheet) or three user provided, powered, solenoids & test gases
Data Logging Built In: The last ten calibrations as well as the last ten error messages are stored within the
analyzer at all times and can be viewed through the firmware at the HMI or software via PC. User selected
PV's can also be logged over time and can be downloaded via USB stick or software.
Security: If operator access control is required then each sub-menu can be locked out using a four digit
security pass-code. These codes can be entered through the keypad or via the OXYvisor software.
MODBUS RTU
The OXYvisor is equipped with digital communication via MODBUS RS485 serial. This two-wire two-way
communication signal can be used to poll measurement values, reconfigure firmware, perform Test Gas
Insert for remote validation or to initiate an AutoCal of the analyzer.
