Figure 27: Hardware Status Page
The Hardware Status Page is divided into several sections.
4.4.3.1 Analog Inputs.
The Analog Inputs section shows the current calibrated inputs to the analyzer’s five analog inputs.
By default, only the first (Cell Pressure) and fifth (PID RTD) are calibrated from the factory; the
other three analog input readings can be ignored. If the user connects additional measurement
devices to the other three available analog inputs, the readings from those additional
measurement devices will be indicated here once the analog inputs are correctly calibrated.
4.4.3.2 Analog Outputs
The Analog Outputs section shows the current output, in mA, from the AccuLase-GPA™ analog
output(s). The current output indicated here for each analog output will either be 3mA (fail-safe,
indicates Bypass mode is active) or between 4 and 20mA. The AccuLase-GPA™ is configured by
default with only one analog output per stream, so if the analyzer is configured to only analyze a
single sample stream, it will only have one analog output.
4.4.3.3 Digital Inputs
The Digital Inputs section shows the current status of the analyzer’s four Digital Inputs. If the circle
for each digital input is grey, this indicates that no signal is being received on that digital input. If
the circle is green, that indicates that a signal is being received on that digital input. If one or more
digital inputs have incomplete circuits between the digital input and an external device, the words
‘Wire Break’ will be indicated underneath the status indicators for the digital inputs.
4.4.3.4 Solenoids
The Solenoids section shows the current status of the analyzer’s solenoids. The AccuLase-GPA™
can control up to eight solenoids, but in most hardware configurations the number of attached
solenoids will be fewer. Solenoids that are actually connected to the analyzer will have descriptive
titles, while solenoid drivers with no solenoids connected will be marked with the term ‘Spare’.
