174 ACF5000 FTIR ANALYZER SYSTEM | OI/ACF5000-EN REV. A
Process status
Definitions
The Process status (see below) provides information on measured values
and the process being monitored by the analyzer system.
The System status (see page 175) provides information on the status of the
analyzer system itself.
Process status
The term "process status" includes
Transgression of measuring range limits
Transgression of limit values
by the measured values.
Transgression of measuring range limits
If the measured value of a component is > +130% or < −100% of the span,
the measured value for the component flashes in the display. A status mes-
sage is also generated in each case; these messages will not be entered into
the logbook.
The thresholds established cannot be changed.
Transgression of limit values
If a measured value is above or below a limit value, this status is output as a
binary signal at one of the digital outputs.
Two prerequisites must be met to this effect:
The limit value must be assigned to a digital output by means of func-
tion block configuration.
The limit value monitoring parameters (direction of action, threshold
value, hysteresis) must be set (see page 110).
The assignment of limit values to certain digital outputs is factory-set; this
is documented in the device data sheet.
