System Organization
The Model 5100E has two types of operational modes
–
User-type, and Operating-type. User modes are
initiated and controlled by the user, and are used to setup and maintain the analyzer. The User modes are:
Calibration, Set/View Alarm-1, Set/View Alarm-2, View Active Faults, and Setup. Operating type modes are
controlled automatically by the Model 5100E during normal operation, according to its programming, and
its configuration parameters. The Operating modes are: Self-Test & Warm-up, Run, Alarm-1 Active, Alarm-
2 Active, and Fault Active.
3.2
USER Modes
Once the analyzer has stabilized, the user can initiate any of the user modes either from the control panel
or through the service port. Control panel access of the Calibration, Set/View Alarm-1, Set/View Alarm-2
and View Active Faults modes will be covered in this chapter. System Setup mode and user access via the
service port will be covered in section 4.1.
The user modes Calibration, Set/View Alarm-1, Set/View Alarm-2 and View Active Faults are accessed via
the cont
rol panel, in the aforementioned order by repeatedly pressing and releasing the “MODE” key.
When a user mode is accessed via the control panel, the Model 5100E aborts any operating mode that is
active, and holds the state of Alarm-1, Alarm-2, and Fault, and Heater OK relay outputs until the user
returns the unit to Run mode.
3.2.1
CALIBRATE Mode & Calibration Procedure
Calibration mode allows the oxygen sensor and analyzer to be aligned to gases of known oxygen
concentration for accurate on-line readings. Facory calibration has been performed at 0 (less than 100
ppm), and 20.9% or 95.0% depending on your range selection. Refer to the Software Setup Log (that is
supplied by the factory) for the configuration details of your Model 5100E.
3.2.1.1
Step-1;
Remove the Oxygen Sensor from Online Service
The oxygen sensor requires removal from on-line service to perform calibration. Calibration or other
maintenance of the Model 5100E analyzer and sensor should be performed when the measured process is
not operating. If the unit has been installed with a Neutronics Inc process sampling system, please refer to
the equipment manual for detailed instructions.
Warning
Before opening any part of the sampling system to air, make sure that the sampling
lines are not pressurized, and are clear of any gas that may create a personnel or environmental
hazard.
