Installation, Operation and Maintenance Manual
OXYvisor Optical Oxygen Analyzer
Follow the steps below to configure and trigger the Test Gas Insert feature of the OXYvisor. If you have already
setup the Test Gas Insert previously, via the software or the HMI, you can proceed to steps 3 and 4 to activate
and deactivate this feature manually.
Before configuring the Test Gas Insert, ensure that the auto calibration has been enabled [Address- 40131 (1
to activate and 2 to deactivate)].
1.
To set the test gas insert time, set the value in minutes between 1-100 to address 40405
2.
Set the test gas insert output to either Zero Gas (0X01) or Span Gas (0X02) to address 40407
3.
Activate test gas insert (0x01), address 44009.
4.
Deactivate/stop the test gas insert before specified time, set value (0x02) to address 44009.
The Auto-Cal feature in the OXYvisor has 4 different schedules. Each schedule can be activated/deactivated,
set up for 1st calibration time and calibration interval individually. First Schedule = [0], Second Schedule = [1],
Third Schedule = [2], Fourth Schedule = [3]
Follow the steps below to setup and trigger the Auto-Cal feature of the OXYvisor. If you have already setup
the Auto-Cal previously or via the software or the HMI, you can proceed to steps 15 and 16 to activate and
deactivate this feature manually. [Address- 44000 (write 4 to activate and 5 to deactivate)].
1.
Set the auto calibration type (Register Address: 40130). The value can be either Dry Gas (0X01) or
Humid Gas(0x02).
2.
Turn off auto calibration (Register Address: 40131). The value should be set to (0x02).
3.
Deactivate each calibration schedule (Register Address: 40132, 40142, 40152, 40162). The value
should be set to (0x02).
4.
Set the calibration interval for each schedule (Register Address: 40138, 40148, 40158, 40168). The
value should be between 0 – 5184000 which is 60days in seconds. For example, calibration interval of 1
calibration a day is 86400 seconds. Calibration interval of once a week is 604800 seconds. The value to write
to the register is in seconds.
5.
Set the first calibration time for each schedule(Register Address : 40140, 40150, 40160, 40170). The
value should be between the current time in seconds (UTC time) + the UTC time within the next 60 days.
For example, if the current date and time is February 13th, 2018 – 5:00PM, the UTC value in seconds is
