Installation, Operation and Maintenance Manual
OXYvisor Optical Oxygen Analyzer
Output Hold Action
:
This screen allows user to set the Auto Time-Out (1 - 99 min) function. When the user enters any of the sub-
menu screen via the HMI, the 4-20 mA output is held. The Output Hold Action determines how much time after
inactivity at the HMI to automatically time-out and exit back to the main and alternate measurement screens
and release the hold on the 4-20 mA.
Temperature Input
:
This screen allows user to select the temperature input from either a RTD (PT100 or PT1000), Temperature-
External (Analog Input) and Manual Input.
RTD (Pt100 or Pt1000)
- Default is PT1000.
Temperature-External (Analog Input)
- This selection will assign the Analog Input (AI) as the temperature
input. A 4-20 mA temperature transducer or transmitter is required
Enter
the 4-mA (5 - 212 F) and 20 mA (5 - 212 F) points of the transmitter range.
Manual Input
- Enter a manual temperature for a static process or temporarily for a failed RTD where
the process temperature is know and does not relatively vary much.
Pressure Sensor Input
:
This screen allows user to select the pressure input from either the on-board Ambient Pressure Sensor, a
Pressure External (Analog Input) and Manual Input.
Ambient Pressure Sensor
- This is the default selection. The sensor is located on the boards within the
main enclosure and measures the local ambient pressure. This choice is common for installations with sample
stream and conditioning panels venting to atmosphere. Be mindful not to install restriction after the oxygen
sensor that may create back-pressure during process measurement or calibration.
Absolute Pressure - External (Analog Input)
- This selection will assign the Analog Input (AI) as the pressure
input. A 4-20 mA pressure transducer or transmitter is required.
Enter
the 4-mA (0 to 82737 mBar) and 20 mA (0 to 82737 mBar) points of the transmitter range.
Absolute M
anual Input
- Enter a manual pressure input for a static process or temporarily for a failed
input where the process pressure is know and does not relatively vary much.
