1 Safety Regulations
1.1 Correct Use
The S5000 Gas Monitor, hereafter also called device, is a gas monitor for measuring toxic and
combustible gases as well as oxygen. Using sensors, the device tests the ambient air and triggers
the alarm as soon as the gas exceeds a specific concentration level.
WARNING!
Read this manual carefully. The device will perform as designed only if it is used, installed and
maintained in accordance with the manufacturer's instructions. Otherwise, it could fail to perform
as designed and persons who rely on this device for their safety could sustain serious personal
injury or loss of life.
WARNING!
Do not use silicone-type lubricants in assembling the device and do not allow silicone vapors to
be drawn into the flow system while in operation. Silicone can desensitize the combustible gas

2.4 Dual Sensing
The S5000 supports two Digital Sensors, or one IR400 point IR detector and one Digital Sensor
simultaneously with four wire connections. However, the device will only support one passive
sensor, either combustible catalytic bead or metal oxide semiconductor (MOS) sensors, based on
the ATO configuration. Passive catalytic bead uses three wires, passive MOS uses four wires.
The S5000 Gas Monitor generates two independent analog outputs; one for each sensor
connected to the transmitter. The analog output associated with Sensor 1 also has the digital
HART (Highway Addressable Remote Transducer) communication superimposed on the analog
signal. If two sensors are connected, the digital HART communication carries information for both
sensors.
2.5 Retrofit Installations
The S5000 has the conduit entries located in the exact same orientation and distance from the
wall and the mounting holes for attaching to a wall are identical to the S4000 Series detectors.
Users will be able to re-use the existing wiring for the remotely mounted sensors.
2.6 XCell Sensors Optimized for Fixed Gas Applications
XCell toxic and combustible catalytic bead sensors are developed and manufactured by MSA.
Now optimized for fixed gas applications, the XCell sensor platform is available in the S5000 and
provides multiple benefits, including a standard 3-year warranty on all XCell sensors.
One important optimization for fixed gas was incorporating the GM catalytic bead into the XCell
sensor.
The XCell Oxygen sensor does not use lead, but rather a non-consuming reaction chemistry. The
XCell Oxygen sensor is expected to last well over 3 years and can be safely stored on the shelf
for at least 1 year without sensor performance degradation.
2.7 TruCal Sensing Technology for CO and H2S Electrochemical Sensors
Using patented pulse check technology and proprietary Adaptive Environmental Compensation
(AEC) algorithms, XCell sensors wtih TruCal verify operation.
Automated pulse checks are the muscle behind the TruCal technology. Every six hours, an elec-
trical pulse stimulates the XCell sensor similar to having actual calibration gas applied, providing
a snapshot of the sensor's sensitivity at the time of the pulse. Using this sensitivity snapshot, the
sensor can diagnose sensor failures like electrode poisoning, electrolyte leaking, or electrical
connectivity issues. The sensitivity snapshots are mapped over time to provide an overall Life &
Health status as either "Good" or "Fair" if the sensor is approaching end of life.
But that's not all. The brains of the TruCal technology lie within the proprietary Adaptive Environ-
mental Compensation (AEC) algorithms. AEC uses the sensitivity snapshots provided by the
pulse check to adjust sensor output, compensating for environmental impacts on sensor accu-
racy. If the AEC adjustment is greater than expected based on typical environmental impact vari-
ations, the transmitter LED’s will slowly flash GREEN, indicating that the sensor should be
calibrated to reset the AEC cycle. The result is a sensor that actively self-monitors for operation
and accuracy, with far fewer manual calibrations.
Actual TruCal sensor performance will depend on the application, background gas exposure, and
environment. To validate XCell sensors with TruCal, it is recommended that users follow their
regular calibration cycle and record the "as found" and "as left" values. This data can be used to
extend the time between calibrations depending on the required specification of the application.

2.8 SafeSwap
The S5000 comes with patented SafeSwap technology, which allows users to change or replace
XCell sensors without needing to power down the instrument. Swap delay is enabled on the
S5000 by default; a feature that gives users a 2 minute window to change sensors without trig-
gering a fault condition. SafeSwap and Swap Delay are only applicable for XCell sensors. For
more information on SafeSwap and Swap Delay, see section 6.

WARNING!
Refer to section 9 "Appendix: General Certification Information" before installation.
Some toxic gases are provided in a fritless sensor housing. The fritless sensor housing is labeled
as Div 2 or Zone 2 and is approved for Div 2 or Zone 2 installations only. The protection method
is Nonincendive or Type n respectively. Ensure all components are approved for the wiring
method being used and in accordance with the National Electrical Code of the country of use, any
applicable local regulations, and this manual.
Failure to follow the above warning can result in serious personal injury or loss of life.
3.4.1 Sensor Mounting Location
The best location for the transmitter and the sensor may not be the same location. Sensors should
be placed in a location where a gas leak is most likely to be detected. When the best sensor place-
ment would not allow the transmitter display to be easily viewed or accessed, a remote junction
box can be used to mount the sensor remotely from the transmitter, allowing both to be installed
in the optimum location.
Two main factors should be considered when choosing a sensor location. The first is the density
of the target gas relative to the air. Gases, such as propane, that are heavier than air should be
placed near ground level while gases that are lighter than air should be placed above potential
leak sources.
Optimum sensor placement will depend on the surrounding processing equipment, such as pipes,
valves, or turbines. MSA offers a gas and flame mapping service that systematically evaluates
potential sources of leaks and recommends detector quantity and placement to create the most
effective detection system.
3.4.2 Transmitter Mounting Location
The transmitter display should be mounted so that the screen is visible and easily accessed after
installation. The electronics assembly inside the enclosure have one orientation inside the cylin-
drical housing. Take care to position the conduit entries and display so that the display is read in
the correct orientation.

3.4.3 Sensor Orientation
WARNING!
Mount the IR400 with the sensor inlet fitting extended horizontally from the main enclosure (Fig.
10) to prevent the build-up of particulate or liquid matter on the monitor's optical surfaces.
Mount the digital sensor with the sensor inlet fitting (Fig. 11) pointed downward; otherwise, the
inlet may become clogged with particulate matter or liquids.
Failure to follow the above warnings may result in serious personal injury or loss of life.
Sensor orientation will depend on the sensor type. If mounting an IR400 point IR sensor, whether
locally on the transmitter or via remote junction box, the sensor should be mounted horizontally.
If the IR400 sensor is not mounted horizontally, the sensor will be prone to more frequent beam
blocking issues due to accumulated dust and condensation on the surface of the IR400 sensor.
Fig. 10 shows the correct and incorrect mounting orientations for the IR400.
Fig. 10 Correct and Incorrect Mounting Orientations for IR400 Point IR Sensor
All other sensors, including electrochemical, catalytic bead, oxygen, passive catalytic bead, and
passive MOS should be mounted vertically with the gas inlet pointed downward. If the sensor is
not mounted with the gas inlet facing down, it is more likely to become clogged with particulate
matter or liquids. Fig. 11 shows the correct and incorrect mounting orientation for digital sensors.
Passive catalytic bead and MOS sensors come already installed on the transmitter housing.

3.4.4 Connecting Sensor to Transmitter Housing or Remote Junction Box
Digital and IR400 sensors are not shipped attached to the main enclosure. The main sensor input
is provided via a four-terminal connection that provides a digital interface for all sensor modules.
Up to two sensors (excluding passive sensors) can be connected to a single transmitter with two
analog outputs capable of representing the readings of the individual sensors.
If planning to install the sensor attached to the transmitter or remote junction box, connect the
sensor before selecting the final mounting location so that the dimensions of the sensor can be
considered.
Passive sensors are shipped already attached and electrically wired to the device. Only one
passive sensor can be used on a single S5000, and they are not interchangeable with other
passive sensors or Digital Sensors. Consider the sensor dimensions when choosing a mounting
location for the transmitter or junction box.
To connect the sensor:
(1) Loosen the set screw located on the lid using a 1.5 mm Allen wrench.
(2) Turn the lid counter-clockwise to remove.
(3) Pull out display module to expose terminal connections.
Fig. 12 Terminal Connections
(4) Route the cable from the sensor through a conduit entry hole in the enclosure so that the
sensor is oriented in the correct position (see section 3.6 for details).
(Repeat to attach a second sensor to the S5000 transmitter).
(5) Connect the sensor to the "Sensor 1" position on the electronics assembly.
a) If using a second sensor, connect it to the second sensor position.
NOTICE
If only using one sensor and it is connected to “Sensor 2” position, the S5000 will enter Sensor
Missing fault. See Disable Sensor in section 4.2.2 for details on how to clear this fault.
