Description
Provides a description of the solenoid’s function, such as, Zero Calibration, Span
Calibration, Stream 1, etc. The description can be edited by left clicking on the
description, typing in the new description, and pressing Enter.
Reverse Logic
If this option is chosen, the solenoid will be energized (gas connected to the NC
port will flow) when inactive, and de-energized (gas connected to the NO port
will flow) when active. If the option is not selected, the solenoid will be de-
energized when inactive, and energized when active.
4.4.14.3 Analog Outputs
The AccuLase-GPA™ can be configured with as many as four hardware 4-20mA analog outputs,
and each analog output has several configurable parameters associated with it. These parameters
are described in Table 16.
Table 16: Analog Output Configuration
Parameter
Explanation
ID
The hardware ID for the analog output on the IO board. The ID number for the
analog output in the web GUI is the same as the analog output number printed
on the IO board.
Enable
If this checkbox is checked, the analog output will be enabled and output an
electrical current; if it is not checked, the analog output will be disabled and will
not output an electrical current.
Description
Provides a description of the analog output’s function. The description can be
edited by left clicking on the description, typing in the new description, and
pressing Enter.
Low Limit
The value entered into this field will be the value for the chosen output
parameter that will be associated with an electrical current reading of 4mA. In
most cases, the low limit field will have a value of zero.
High Limit
The value entered into this field will be the value for the chosen output
parameter that will be associated with an electrical current reading of 20mA. If
the parameter being output is concentration, the value in this field will typically
be the analyzer’s maximum range concentration.
Bypass Use Failsafe
If this checkbox is checked, when the analyzer is placed into Bypass mode, the
analog output will output the failsafe electrical current of 3mA. If this checkbox is
not checked, the analog output will continue to output ‘live’ values even if the
analyzer is in Bypass mode. The default is to check this checkbox.
Parameter
The specific parameter to be output on the analog output. The parameter to be
output can be chosen from the drop-down menu that shows all possible output
parameters. The default configuration would be to have Analog Output 1 output
Stream 1: Concentration, Analog Output 2 output Stream 2: Concentration, and
so on.
4.4.15 Analog Inputs Page
The Analog Inputs page is used to configure and calibrate each of the five available analog inputs,
as well as their associated alarms, on the AccuLase-GPA™ IO board. It is shown in Figure 47.
