Outputs
Analog output 1 defaults as Loop 1 PV retrans except when PVT = Simple Nitrider (output 1 is H2 0 – 100%)
Analog output 2 defaults as Loop 1 control except when PVT = Simple Nitrider (output 2 is DA 0 – 100%)
Relay 1 is always loop 2 control (HP temperature)
Relay 2 is always input 2 high limit
Relay 3 is loop 1 control increase (gas) except when PVT = %Oxygen (Relay 3 is loop 1 control decrease)
Relay 4 is loop 2 control decrease (air) except when PVT = %Oxygen (Relay 4 is loop 2 control increase)
Relay 5 is always sample pump for HP except when PVT = Probe Redundancy (Relay 5 is probe select)
Relay 6 is always probe burnoff
Relay 7 is selectable alarm output (any combination)
Relay 8 is always general alarm output (any alarm)
Alarms
Alarm 1 is always process high on input 2
Alarm 2 is fully assignable
Alarm 3 is fully assignable
Digital Inputs (Event Inputs)
Digital Input 1 (event In 0) selects probe 1 when PVT = Probe Redundancy only
Digital Input 2 (event In 2) selects probe 2 when PVT = Probe Redundancy only
Digital Input 3 (event In 2) inhibits sample pump for HP only
Digital Input 4 (event In 3) starts probe burnoff when PVT = % Carbon, Dew Point, % Oxygen, or Millivolts
Note: Probe burnoff is available only for PVT types: % Carbon, Dew Point, % Oxygen, and Millivolts . No
impedance test.
Note: Dew Point is calculated only for PVT types: % Carbon, Dew Point, % Oxygen, and Millivolts
