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!
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 sensor, thereby giving erroneously low readings.
Use only genuine MSA replacement parts when performing any maintenance procedures provided in this manual. Failure to do
so may seriously impair sensor and gas monitoring performance, alter flameproof/explosionproof characteristics or void
agency approvals.
Failure to follow these warnings can result in serious personal injury or death.
WARNING!
As with all gas monitors of this type, high levels of, or long exposure to, certain compounds in the tested atmosphere could
contaminate the sensors. In atmospheres where an S5000 Gas Monitor may be exposed to such materials, calibration must be
performed frequently for dependable operation and to confirm that display indications are accurate.
These effects include, but are not limited to:
• Passive MOS sensors may be adversely affected by prolonged exposure to certain substances. Loss of sensitivity or
corrosion may be gradual if such agents are present in low concentrations or it may be rapid at high concentrations.
Examples of these substances are as follows:
○ Halides: compounds containing fluorine, chlorine, bromine and iodine
○ Heavy metals, e.g. tetraethyl lead
○ Caustic and Acidic liquids and vapors
○ Glycol
• The H2S Digital Sensor may be adversely affected by the following substances:
○ Alcohols (methanol, ethanol, isopropanol)
○ Nitrogen dioxide (NO2)
○ Chlorine (Cl2)
○ Paint solvents (acetone, turpentine, toluene, mineral spirits, etc.)
• The CO Digital Sensor may be adversely affected by the following substances:
○ Alcohols (methanol, ethanol, isopropanol)
○ Paint solvents (acetone, turpentine, toluene, mineral spirits, etc.)
•The O2Digital Sensor may be adversely affected by the following substances:
○ Long term exposure to low levels of Acetylene
○ Paint solvents (acetone, turpentine, toluene, mineral spirits, etc.) in high concentrations larger than 1000 ppm or
prolonged exposure to lower concentrations
• Prolonged exposure of the H2S Digital Sensor to humidity levels of 5% RH or lower will result in gas measurement
readings of H2S that are greater than the actual gas concentration present.
5
1 Safety Regulations US

• It is not recommended to expose the O2, H2S and CO Digital Sensors to environments containing oxygen levels above
30% (v/v) or below 5% (v/v). The O2sensor will operate at concentrations below 5% (v/v) but not for prolonged periods of

2 Description
2.1 Display
The S5000 utilizes a dot matrix LED display, capable of displaying four alphanumeric characters at a time. The display will
scroll words that exceed four letters. Most of the messages scroll twice across the screen before moving onto next selection.
Figure 1 S5000 Main Display
In addition to the red LED display, the S5000 uses six icons to indicate status. Green LED indicates power supply status. A
yellow triangle and red bell indicate fault and warning or alarm conditions respectively. The Bluetooth icon indicates that the
Bluetooth wireless technology is enabled on the device. Yellow "1" and "2" icon indicate which sensor gas reading is being
displayed, or during configuration which sensor's options are being accessed.
2.2 No Tool Interface
The S5000 does not require any tools or third party devices to change settings, reset alarms or perform any maintenance
operation. The EZtouchbutton works through the glass and does not require opening the explosion proof enclosure. The
EZtouchbutton works with bare fingers or with gloved hands, so long as the gloves are not black. See 4 Operation for more
information on navigating the menu with the EZtouchbutton.
Figure 2 Interface
The user menu can also be accessed using the round GM magnet on the General Monitors logo.
2.3 Bluetooth®Wireless Technology
The S5000 comes by default with Bluetooth communication. Using the X/SConnectApp on an appropriate smart phone or
tablet, users are able to interface with the S5000 menu options in a larger and more user friendly setting. The Bluetooth
8
2 Description US

communication can interact with the device within a maximum transmission distance of 70feet (21m).
WARNING!
Bluetooth operation is dependent upon signal availability of the wireless service(s) necessary to maintain the communication
link. Loss of wireless signal will prevent communication of alarms and other information to linked devices. Take appropriate
precautions in the event a loss of wireless signal occurs.
Failure to follow this warning can result in serious personal injury or death.
If ordered with Bluetooth, the device will be shipped with Bluetooth enabled. See 4 Operation for instructions on
disabling Bluetooth.
If the device was not ordered with Bluetooth it cannot be upgraded.
The S5000 and user provided communication device will need to be paired. This requires both devices to be in range and for a
pairing sequence inputting a 6digitpairing code. The instructions will be displayed on both the S5000 and communication
device.
There are communication devices capable of being used in classified areas. Please contact your MSA
representative for additional information.
2.4 Dual Sensing
The S5000 supports two digital sensors, or one IRsensor 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. Changes in barometric pressure across the range of 86 kPA - 108 kPA have a negligible effect on the operation of
the sensor.
9
US 2 Description

2.7 TruCal Sensing Technology for CO and H2S Electrochemical Sensors
Using patented pulse check technology and proprietary Adaptive Environmental Compensation (AEC) algorithms, all XCell
sensors with TruCal verify operation by actively adjusting the sensor output for changes in sensitivity. Some XCell sensors
with TruCal also include Diffusion Supervision, which monitors the sensor inlet for obstructions that could prevent gas from
reaching the sensor.
Every six hours, an electrical 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.
AEC uses the sensitivity snapshots provided by the pulse check to adjust sensor output, compensating for environmental
impacts on sensor accuracy. If the AEC adjustment is greater than expected based on typical environmental impact
variations, the transmitter LED’s will slowly flash GREEN, alerting users that the sensor should be calibrated to reset the AEC
cycle. Users can also enable a Calibration Alert function that will send a milli-amp signal on the analog output to the control
room. The result is a sensor that actively self-monitors for operation and accuracy, with far fewer manual calibrations.
Diffusion supervision actively monitors the sensor inlet for obstructions. If an obstruction is detected, the sensor will go into a
fault mode to alert users and the control room that it is not seeing gas due to an obstruction. Objects residing directly on or in
the sensor inlet that result in a significant impact to the gas path are very likely to be detected by Diffusion Supervision.
Examples include paint, tape, water, and dirt. Small amounts of these materials can be visible on the inlet while not impacting
the gas path enough to trigger a Diffusion Supervision Fault. A fault signal will only be sent out when the system determines
that the amount of material that has accumulated on or inside the sensor inlet is negatively affecting the gas path.
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 triggering a fault condition. SafeSwap and Swap Delay are only applicable for
XCellsensors. For more information on SafeSwap and Swap Delay, see 6 Maintenance.
WARNING!
• As part of the product certification, it was verified that optional communication functions of this gas detection instrument
while operating at the maximum transaction rate do not adversely affect the gas detection operation and functions of the
instrument. The product certification, however, does not include or imply approval of the SafeSwap feature,
communications protocol or functions provided by the software of this instrument or of the communications apparatus
and software connected to this instrument.
• Follow the warnings below when removing or replacing sensors. Reference Figure 3 Exploded View for component
overview.
○ Never remove or replace a sensor body assembly or an IRSensor while under power or when explosive hazards
are present.
○ Confirm that the area is free of explosive hazards before removing or replacing an XCell Sensor under power.
○ To remove an XCell Sensor, unscrew XCell Sensor three full turns, wait 10 seconds, and then remove the XCell
Sensor completely.
Failure to follow these warnings can result in serious personal injury or death.

• Attach appropriate sensor to housing or junction box (see 3.4.3 Sensor Orientation for proper sensor orientation)
• Mount transmitter or junction box using appropriate mounting hardware
• Confirm free air flow around the sensor
3.4 Mounting
WARNING!
Refer to 9 Appendix: General Certification Information before installation.
15
US 3 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 this warning can result in serious personal injury or death.
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 placement 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 cylindrical 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 IR Sensor with the sensor inlet fitting extended horizontally from the main enclosure (see Figure 10 Correct and
Incorrect Mounting Orientations for IR Sensor) 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 (see Figure 11 Correct and Incorrect Mounting Orientation for Digital
Sensors) pointed downward; otherwise, the inlet may become clogged with particulate matter or liquids.
Failure to follow this warning can result in serious personal injury or death.
Sensor orientation will depend on the sensor type. If mounting an IRSensor, whether locally on the transmitter or via remote
junction box, the sensor should be mounted horizontally. If the IR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 IRSensor. Figure 10
Correct and Incorrect Mounting Orientations for IR Sensor shows the correct and incorrect mounting orientations for the
IRSensor.
16
3 Installation US

Figure 10 Correct and Incorrect Mounting Orientations for 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. Figure 11 Correct and Incorrect Mounting Orientation for Digital
Sensors shows the correct and incorrect mounting orientation for digital sensors. Passive catalytic bead and MOS sensors
come already installed on the transmitter housing.
Figure 11 Correct and Incorrect Mounting Orientation for Digital Sensors
3.4.4 Connecting Sensor to Transmitter Housing or Remote Junction Box
Digital and IRSensors are 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.
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.
