without risk to the operator. Modifying the analyzer to operate
with the cover open can injure personnel.
WARNING!
Bypassing the analyzer interlock switch to open the case
cover during analyzer operations can cause serious bodily
injury. Even though the analyzer provides a second layer of
protection, such as a laser cover to prevent the user from
the invisible laser beam or any secondary reflection from
the laser on a reflective surface, it is not recommended to
modify the analyzer to operate in an unsafe condition.

...4 Safety
NOTE
Save the original shipping materials to use when returning
the analyzer to ABB if factory service or repair is needed.
Internal Laser-Interlock Switch
The internal laser-interlock switch disables the laser by
removing its power: This prevents exposure and eye damage
caused by the class 3B laser from primary and secondary
reflections in the OA-ICOS module. The laser interlock switch
and key are shown in Figure 1. The switch is located on the left
side panel toward the front top corner of the analyzer. The
physical key is mounted on the shroud. When lowered so that
the switch and key are in close proximity, it signals the Laser
Controller/Driver board that the interlock is closed, enabling
power to the laser(s).

The analyzer is a cavity-based spectroscopy instrument. The
analyzer’s cavity design enhances the absorption of laser
light by the target gas molecule. This enhancement improves
the signal-to-noise ratio over conventional laser sensors
enabling trace gas measurement and sensitive monitoring.
The type of gas the analyzer can measure is based upon the
laser wavelength used. ABB provides a variety of models,
each targeting gases that various industries monitor. All
measurements are real-time.
Connection Ports
This section describes the connections shown in Figure 4.
6 Features and Measurement
Theory
Figure 4 Connection Ports
Figure 5 COM/DC Out Pinouts
Figure 6 Plumbing Diagram
Gas Inlet
The gas to be measured is connected to the ¼ inch push-
connect INLET port.
During normal operation, the pump draws the sample through
the analyzer inlet and exhausts the sample through the
ventilation holes of the case. The acceptable inlet gas-pressure
range is 0 to 15 psig.
Power
The analyzer is powered 11-30 V DC to the DC power inlet
with a 5 A / 32 VDC automotive fuse inside the power-input
harness. Power can be supplied using the 120/240 V power
cable supplied with the analyzer or from the UAV batteries (if
applicable, refer to the HoverGuard™ Solution System Manual ,

Data Interface
• USB ports – used to transfer data to a USB memory device or
connect a USB keyboard and mouse.
• WiFi External Antenna port – allows for wireless connection to
the analyzer via an externally connected antenna. Note that the
external antenna, packaged with the analyzer, must be
attached prior to powering on the analyzer.
• COM/DC Out ports (15 pin Micro-D Connector) – real-time
digital input and output measurement data, as well as power,
+5 V DC and +12 V DC, for external devices (for example,
anemometer, auto pilot). See Figure 5 for pinouts.
Plumbing Diagram
The internal flow of gas through the analyzer is shown in
Figure 6.
The gas enters the sample inlet (IN) and is initially filtered
through a 5 µm screen filter. It then enters the optional
pressure controller, which regulates the pressure to maintain
a specific setpoint. Before the gas travels through the optical
cell to the pump, it passes through an additional filter that is

VNC Server First-Time Activation
By default, the VNC server is not active on a new factory
analyzer because it uses an unencrypted communication
protocol. To enable VNC connections, you must perform a one-
time activation of the VNC server. This is done through a
remote SSH connection, as shown in Figure 11.
1 Use an SSH client to remote login using the analyzer IP
address.
a. User: lgr
b. Password: 3456789 (the default SSH password)
2 Type the following command into the prompt to execute the
activation script:
./enableVnc.sh
3 Type yes at the prompt to accept the security disclaimer.
4 The VNC server should now be running and will automatically
start each time the analyzer is powered on.
VNC Viewer User Interface
The VNC Viewer® application must be installed on a tablet,
cell phone, or laptop PC, to allow a wireless remote-control
connection between the analyzer and the interface.
The analyzer uses VNC Viewer® by RealVNC Limited for
communication between the user and the analyzer. VNC Viewer
(Figure 12) can be downloaded from Play Store for Android
devices, App Store Apple OS devices, or directly from the
RealVNC Internet site for PC or Mac installation
(www.realvnc.com).
The following procedure is for a Windows machine to establish
communication with the analyzer using VNC Viewer. A label
showing the SSID, network key, and analyzer IP address is
affixed to the bottom of the analyzer. (If the key has been
changed as described in Step 7 in the WiFi Setup section above,
use the new key.)
1 Connect to the analyzer’s WiFi network:
a. Once VNC Viewer is downloaded and installed on the
tablet or laptop, power on the analyzer and wait
approximately 2 minutes for the WiFi router to boot up
completely.
b. Connect the computer or laptop to the analyzer WiFi
network.
2 Search the available networks to find an SSID in the form,
RUT240_xxxx (where xxxx varies with the analyzer) and click
Connect.
3 Enter the network security key: from Figure 7 (or modified
security key).
4 Ensure that a network connection is made.

Numeric Display
The Numeric display is the default display and one of the
simplest screens for go/no-go decisions based strictly on
gas concentration measurements. Sample gas is measured
in parts per million (ppm). The resolution unit auto-adjusts.
Figure 22 shows an example of numeric readout of the last

parts per million (ppm). The displayed numeric readout may
vary, depending on the analyzer type. In addition, the analyzer
color-coded operational status is indicated (for details on
color-coding, refer to Alarm Status Display - Figure 26).
Spectrum Display
The sample Spectrum display provides additional information
on the measured gas: the analyzer sensitivity level shown
in the Transmitted Intensity diagram, the absorption level,
a theoretical fit to the measured target gas(es), and the
ringdown time which is indicative of whether or not the high-
reflectivity mirrors require cleaning.
The Spectrum screen displays peaks related to different gases.
The measured concentrations are shown in ppm on the bottom
of the Spectrum display. (Figure 23)
The transmitted intensity also provides important information
about the analyzer measurement module light source. A drop
in intensity may indicate an issue with the laser, detector, OA-
ICOS module mirrors, or supporting electronics board. This
information is helpful when contacting ABB service about the
issue.

Timechart Display
The Timechart display (Figure 24) provides the absorption (in
ppm) of the sample gas measured. The black line represents the
trace of measured concentrations at a customizable interval
rate.

Alarm Status Display
The Alarm Status display (Figure 26) indicates the real-time
analyzer operational status. The status uses traffic-light color
indication.
• Green indicates no problem.
• Yellow indicates the analyzer is out-of-spec or maintenance
is soon required.
• Red indicates there is a problem, and maintenance is
immediately required.
Error messages for each alarm can be displayed by selecting
the relevant alarm button: After the button is selected, a pop-
up window appears displaying the messages.
