4.3 The Analysis 1 Tab
The Analysis 1 tab (Figure 4-1) presents a summary of the present status of the system
4.3.1 Online/Offline Button
Clicking the Online / Off Line button changes the status from On Line (green) to Off Line (red)
and vice-versa. When the analyzer is changed to Off Line, the relay indication for Control is
forced to the Manual state (amber).
The state of the On Line / Off Line button does not affect the operation of the analyzer. The
ability to remotely signal plant operations using the relay output of the Control (in conjunction
with the On Line / Off Line button) has been incorporated as a convenience to the user. The
On Line / Off Line function essentially provides a method of signaling that the analyzer data is
invalid (undergoing maintenance or servicing).
When returning the analyzer to Online status, the relay indication for Control will return to the
Auto state only if no fault or calibration conditions exist.
The plot displays the H
2
S concentration as a function of time. The range for the x and y axes
can be edited as described in Section 4.8.
4.3.2 H
2
S Field
The H
2
S, field indicates the present value of the concentration and cannot be edited. The
analyzer physical scaling is optimized for the measurement of the typical H
2
S concentration in
the acid gas.
