Installation, Operation & Maintenance Manual
OXYvisor Optical Oxygen Analyzer
Digital Output
This screen allows user to set the Digital Outputs as alarm relays assigned to a specic PV, SV, error code or
general code. The programming allows for input of a set-point and ability to set the normal state as open or
close with deadband to prevent chatter. If AutoCal routine is enabled then DO1, DO2 and DO3 are reserved
for AutoCal until it is inactivated. DO4 is always available as an alarm/relay.
Assign the Relay - Default is Disabled. Select from Oxygen, Error Code or Process Temperature
Set-Point - Enter the SetPoint for the alarm (either high or low)
Normal-State -Assign Normal State Open or Closed
Deadband - Assign the the set-point as high or low. Enter the Deadband in % O2.
Remote Digital Input - (AutoCal must be enabled for this screen to be accessed)
This screen allows user to program the setting associated with the Test Gas Insert function otherwise know as
Validation. The Test Gas Insert allows for remote activation of either the span or zero calibration gas, while
isolating from the process and active 4-20 mA outputs. This allows end user to remotely observe dynamic
results to a known standard, therefore validating the performance of the analyzer. The Digital Input 1 (DI1) is
permanently assigned to AutoCal. DI2 is as follows:
Digital Input 2 - Test Gas Insert
Time Period for Gas - Enter the time for the Test Gas Insert to ow
Dene which output - Select the Zero or Span gas
Analog Output (1&2)
This screen allows conguration of the fully programmable Analog Outputs.
Enable Analog Output - This must be selected for the output to be active.
Assign Parameter to the 4-20 mA. Select from O
2
, Temp, phase angle, intensity and process pressure.
Assign Critical Fault - Scroll to bottom of AO menu and nd “Output Signal Critical Fault”
Fault Direction - Select to fail HIGH (20mA) or LOW (4 mA)
Enable Namur Signaling - Yes/No. Select YES will extend the Fault Direction critical failure to
HIGH (21 mA) and LOW (3.8 mA).
Linear - Enter the 4-mA and 20 mA [range is dependent on Sensor Type and Media selections]
Bi-Linear - Enter the 4-mA and 20 mA [range is dependent on Sensor Type and Media selections]. Then
enter the Bi-Linear break-point by either the mA value or the oxygen value.
