1.5 System Operating Control
The analyzer system operation is controlled by a dedicated data acquisition system which
provides supervisory control, performs all calculations and provides the user interface.
The system includes an onboard computer system which provides a graphic display of key
system control parameters and their status, a digital display of the instantaneous value of the
Air Demand, H
2
S, SO
2
, and COS, and historical graphic displays of the Air Demand, H
2
S and
SO
2
. The display monitor is mounted on the door of the control cabinet. Cabinet access is not
required for viewing or operation.
The Air Demand, H
2
S, SO
2
, and AO4 outputs can be configured as loop-powered 4 – 20 mA
signals and the system status can be provided via relay contacts. As an option, the AO4
output can be configured to output Air Demand, H
2
S, SO
2
, COS, Sigma S (the sum of the
H
2
S and SO
2
concentrations), or H
2
S/SO
2
ratio. An RS485 serial port is also provided which
can be used for available for Modbus communication.
A hand held key pad is provided for user interface with the analyzer. Operation of the system
with the keypad is described in Section 4.2. As an alternative, a web based graphical user
interface (GUI) can be used to view and enter information on a remote basis (Section 4.3).
