1.1Correct 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 O2 Digital 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
General Monitors S50007
US
1 Safety Regulations
•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.
•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 time.

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.
2.2No Tool Interface
The S5000 does not require any tools or third party devices to change settings, reset alarms or perform any maintenance
operation. The EZtouchbutton works through the glass and does not require opening the explosion proof enclosure. The
EZtouchbutton 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 EZtouchbutton.
General Monitors S500010
US
2 Description
Figure 2 Interface
The user menu can also be accessed using the round GM magnet on the General Monitors logo.
2.3Bluetooth®Wireless Technology
The S5000 comes by default with Bluetooth communication. Using the X/SConnectApp 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
communication can interact with the device within a maximum transmission distance of 70feet (21m).
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 6digitpairing 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.
2.4Dual Sensing
The S5000 supports two Digital Sensors, or one IRSensor 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 Sensor1 also has the digital HART (Highway Addressable Remote Transducer)
General Monitors S500011
US
2 Description
communication superimposed on the analog signal. If two sensors are connected, the digital HART communication carries
information for both sensors.
2.5Retrofit 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 S4000Series detectors. Users will be able to re-use the existing wiring for the
remotely mounted sensors.
2.6XCell 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 XCellsensors.
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 3years 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.
2.7TruCal 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.
General Monitors S500012
US
2 Description
2.8SafeSwap
The S5000 comes with patented SafeSwap technology, which allows users to change or replace XCellsensors without
needing to power down the instrument. Swap delay is enabled on the S5000 by default; a feature that gives users a
2minute window to change sensors without triggering a fault condition. SafeSwap and Swap Delay are only applicable for
XCellsensors. For more information on SafeSwap and Swap Delay, see 6 Maintenance.

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 ) 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 ) 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 IRSensor, whether locally on the transmitter or via
remote junction box, the sensor should be mounted horizontally. If the IRSensor 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
IRSensor. Figure 10 shows the correct and incorrect mounting orientations for the IRSensor.
General Monitors S500019
US
3 Installation
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 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 IRSensors 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 1.5mm Allen wrench.
(2)Turn the lid counter-clockwise to remove.
(3)Pull out display module to expose terminal connections.

3.5Installing a Remote Sensor Junction Box
Sensors mounted remotely must use the S5000 junctionbox. The junction box housing is the same construction as the
transmitter. The mounting options and instructions for connecting the sensor are the same for sensors connected directly
to the S5000 transmitter housing. The junction box is available in 316StainlessSteel.
Sensors can be remote mounted up to 100m from the transmitter housing, as long as the S5000 transmitter is mounted
within maximum distance from the power supply, as indicated in Table 1 .
The junction box does not have an illuminated display and has two connectors for attaching a single sensor input and an
output connects to the transmitter. A 16AWG 4element cable with a braided shield should be used for the electrical
connection between the junction box and the S5000 transmitter. Specific cable recommendations are available upon
request.

3.6.1 Electrical Warnings - Read before Connecting Power
WARNING!
•Before wiring the S5000 transmitter, disconnect the power source supplying the transmitter and ensure no hazardous
atmosphere present; otherwise, electrical shock or ignition of hazardous gases could occur.
•Install wiring in accordance with the electrical code of the country in use, the local authority having jurisdiction and
these installation instructions, as applicable.
General Monitors S500027
US
3 Installation
•Do not make any connections to the S5000 main board or junction box input, output, and relay connections while under
power. Making connections under power could lead to electrical shock or ignition of a hazardous atmosphere.
•Ensure that water and dirt are not able to enter the unit via the wire or conduit. If the unit is installed in a location known
to be wet or damp, it is good practice to loop or bend the entry into the unit that prevents water incursion.
•The internal grounding terminal (located on the interior metal board stack plate) must be used for equipment grounding.
The external grounding terminal is only to be used as a supplemental bonding connection where local authorities permit
or require such a connection.
•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 for component overview.
–Never remove or replace a sensor body assembly or an IRSensor 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.
3.6.2 Retrofit Applications with S4000CH, S4000TH, or TS4000H
The S5000 was designed to be easily retrofitted with existing S4000CH, S4000TH, and TS4000H wiring. When replacing
an existing S4000CH, S4000TH, or TS4000H with the equivalent S5000 sensor technology, the following items need to be
checked in order for the S5000 to operate:
(1)Wire gauge needs to be 18-14 AWG
(2)Sufficient power must be supplied to the S5000 in accordance with the maximum wire lengths. (See the tables in
3.6.4 Power Load Requirements and Maximum Mounting Distances)
If these requirements are met, performance of the S5000 should meet the noise immunity standard equivalent of the
S4000CH, S4000TH, and TS4000H using the existing wiring; However, the installation may not meet the latest EMC
EN50270 noise immunity standard that the S5000 meets with the grounding and wiring scheme as indicated in this manual
and corresponding I/O drawing.
3.6.3 Electrical Hardware Requirements
Braided shielded, twisted pair, instrument quality wire or cable should be used to minimize the possibility of noise
interference and contact with other voltages. Selection of shielded cable must comply with local requirements.
Conduit, in addition to braided shielded wire, may also be needed in areas where a large amount of electrical noise is
expected. All cable shields should be terminated to earth ground at one end only.
The S5000 has a four-wire power terminal, one four-wire communication terminal, and three four-wire sensor terminals.
Relays can be added as an option. Terminals for power and relays can take wires up to 12AWG while all other terminals
take wires up to 14AWG. Four conductors are also required for the S5000 remote junction boxes.
General Monitors S500028
US
Incoming power and signal cables should be a braided shield cable such as AlphaWire3248 or equivalent. The braided
shield must be terminated to the board stack as shown in Figure 27 , or alternatively, the earth ground at the user’s power
source location.
An external Class2 power supply is required to supply 12-30VDC to the S5000. Incoming power and signal cables should
be a braided shield cable such as AlphaWire3248 or equivalent.
3.6.4 Power Load Requirements and Maximum Mounting Distances
Consider future needs when selecting cable size and power supply. The maximum distance between the S5000 transmitter
and the power supply depends on the sensor configuration (sensing technology and one or two sensors), wire gauge, and
the power supply voltage. The table below outlines the maximum transmitter mounting distances. First determine if the
sensor(s) will be locally or remotely mounted. Then choose sensor type(s). The corresponding maximum power and
mounting distances by wire gauge are shown.

3.6.6 Relay Electrical and Power Connections
Relay Board Stack Overview
The S5000 can be purchased with three relays. Two of the relays can be configured for either de-energized (default) or
energized and latching or non-latching. The third relay is a dedicated fault relay.
All electrical connections to internal relays can be made directly on the PC board. The board is labeled for Normally Open
(NO) and Normally Closed(NC) de-energized state.

3 Installation
If using ACpower, the relay wires should not be run within the same conduit or cable tray as the DCpower supplied to the
S5000 or the S5000 junction box. A separate wire entry on the device should be used for ACpower connected to the relays.
The S5000 is built with an additional wire entry to allow this.
Exceeding the volt-amp rating of the relay can cause damage to the switching contacts.
Relay Connections to Inductive Loads
If connecting the relays to motors, fluorescent lighting, or other inductive loads, it is necessary to suppress any sparks or
inductive feedback that may occur at the relay contact. These effects may render the unit inoperative.
One way to reduce these effects is to install a Quencharc®(P/N630413) across the load being switched.
Fault Relay Wiring and Configurations
The Fault relay state in non-fault operating condition is Energized and terminal connections are supplied for Normally
Closed and Normally Open.
The energized fault relay setting provides an electrical path for fail-safe relay operation. In the event of any failure, including
loss of power, the relay will change to the de-energized state to indicate a fault condition.
The Fault relay state cannot be reconfigured.
Relay Energy State and Terminal Connections
The S5000 relay states are labeled for the default de-energized state. The alarm/warning relay energy state can be changed
on the device, which will exchange the normally open and normally closed terminals. The preferred relay energy state
should be determined before making connections. Table 9 shows the terminal connections by energy state and is
applicable to both relay1 and relay2.

WARNING!
Refer to 9 Appendix: General Certification Information before installation and operation.
Failure to follow this warning can result in serious personal injury or death.
The S5000 Series gas monitor is factory calibrated and shipped with the most common default options to minimize set up
effort. Using sensors, the device tests the ambient air and triggers an alarm as soon as the gas exceeds a specific
concentration level.
4.1Startup
4.1.1 Initial Startup
The first time the S5000 is powered on, the following will appear on the display:
•S5000
•Software Version No.
•Sensor Warm-up
•Wait
The S5000 will remain in Start-up mode in which the fault relay is de-energized and the analog output is 3.5mA by default.
The time the S5000 stays in Start-up mode depends on the sensor.
Oxygen and Carbon Monoxide sensors require a 30 minute warm-up time before being fully functional. The device will be in
fault during the 30 minute start-up time. All other sensor start-up times vary, the unit will be in fault for the first 2 minutes of
the start-up time and the analog output signal will be at the maintenance level (3.5mA default).
A full calibration is recommended after onehour of a sensor being installed and acclimated to the environmental conditions.
See 5 Calibration for calibration details.
4.1.2 Sensor Warm Up Times
WARNING!
For optimal sensor performance, allow sensors 24 hours to acclimate to application conditions before performing an initial
calibration

Disable Sensor (for Digital Sensors Only)
When removing a sensor from the transmitter while under power, the S5000 will enter a Sensor Missing fault condition after
the twominute SwapDelay period has expired (if enabled). If SwapDelay is disabled, the transmitter will go into SensorMissing fault immediately after removing the sensor from the transmitter. If the system is off at the time a sensor is
removed, the transmitter will go into fault after its startup sequence. This fault condition can be removed by disabling the
affected sensor position.
Disabling a sensor removes the fault and stops communications with the sensor, the sensor’s reading on the display is
removed, and the mAchannel for that sensor position is set to 0mA. By default, the S5000 has the Sensor 2 position
disabled. If at any time a sensor is connected to a position that is disabled, the device will automatically enable that sensor
position.
To disable the sensor after removal:
(1)Go to Sensor Setup menu.
(2)Touch button when Disable appears on screen.

Diffusion Supervision
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.
Even if a Diffusion Supervision Fault has not been triggered, it is good practice to clear any foreign material from
the sensor inlet if any is observed while inspecting the sensor.
To enable or disable Diffusion Supervision:
(1)Go to Sensor Setup menu.

The Life and Health information reports the general health of the sensor.
XCell sensors with TruCal (HydrogenSulfide and CarbonMonoxide) calculate current sensor sensitivity using automated
pulse checks. The pulse stimulates the sensor with a response similar to having actual calibration gas applied. The
stimulated response is compared to the last calibration and will make adjustments to sensitivity to match the last
calibration. When the required adjustment is greater than the accuracy of the algorithm's adjustment, the sensor will call for
a calibration.
All Digital Sensors, including catalytic bead and oxygen, will show life health status as 'Good' or 'Fair' with the
following calculation:
Good condition occurs when the current calibrated span sensitivity is greater than 50% of the way between the
initial calibration sensitivity and the end-of-life span sensitivity. Fair condition occurs when the current calibrated
span sensitivity is less than 50% of the way from the initial calibration sensitivity and the end of life span
sensitivity.
NOTICE
Using expired calibration gas or the incorrect calibration gas can result in a premature "Fair" status.

5 Calibration
5Calibration
Calibration is the process of applying a known quantity of gas to the transmitter so that the transmitter can adjust the
precision and accuracy of the measurements made in normal operating mode. This process ensures that gas
measurements are as accurate as possible.
Calibration Warnings - Read before Calibrating
Although S5000 sensors are factory calibrated, another calibration is recommended once the unit is installed in its final
environmental destination.
WARNING!
Use zero gas when zeroing the S5000 transmitter if there is any possibility of background gas. Otherwise, improper
calibration could occur.
Use zero gas when zeroing IR700 sensors. Air contains CO2and cannot be used. Nitrogen is recommended as a zero gas.
Otherwise, improper calibration could occur.
For optimal sensor performance, allow sensor to acclimate to application conditions for 24 hours before performing an initial
calibration.
Perform calibrations 24 hours after initial start up and at a frequency identified in 5.2 Calibration Frequency and 5.3
Calibration Frequency for XCell Sensors with TruCal (H2S & CO only) .
XCell Sensors with TruCal (CO & H2S) with Calibration Alert enabled provide an indication for “Calibration Recommended”
and “Calibration Required’. When either indication is provided by the device, calibrate the sensor.
Failure to follow this warning can result in serious personal injury or death.
5.1Calibration Equipment
A gas cylinder with a known concentration of gas appropriate for the range of measurement is needed. Sensors come with
preset span gas values appropriate for the measurement range.
All of the calibration hardware for XCell sensors is included in a convenient calibration kit. It includes a carrying case that
can fit two cylinders, a regulator, tubing, and any other accessories required for each sensor type. The calibration kit can be
ordered separately or as a single line item with the gas cylinder. See Table 16 for a complete list of calibration cylinders
and kits.
The Digital Toxic, Oxygen, and Catalytic Bead sensors share the same sensor body design and use the same calibration
hardware. The calibration kit for IR400 sensors is ordered separately (P/N 1400270-2) and contains a regulator, tubing, and
other calibration accessories specific to the IR400. The calibration kit for IR700 sensors is P/N 31478-1.
Passive sensors use different calibration hardware to accommodate the different sized sensor housing. Passive MOS
sensors can be calibrated with either calibration gas cylinders or ampules. See Table 16 for P/N details.
The sensor guard and rubber calibration cap should be removed after calibration.

5.2Calibration Frequency
The frequency of calibration gas testing depends on the operating time, chemical exposure, and type of sensor. Especially
in new installations or applications, it is recommended that the first sensors be calibrated more often to establish the
sensor performance in this particular environment.
For this, record the "as found" and "as left" values and track the percent adjustment over time. Then, gradually extend
calibration intervals until the percent adjustment is greater than the expected accuracy of the sensor.

5.3Calibration Frequency for XCell Sensors with TruCal (H2S & CO only)
WARNING!
Certain conditions may prevent the performance of Diffusion Supervision and/or TruCal testing. If such a condition persists
for 90 days, the XCell sensor with TruCal will recommend a calibration which is communicated through the transmitter
display and LEDs. When Calibration Alert is enabled, the milli-amp signal output will also be driven to calibration alert
output. Perform a calibration when the device recommends it.
Failure to follow this warning can result in serious personal injury or death.
5.3.1 XCell Sensor with TruCal and Diffusion Supervision (CO&H2S Only)
Sensors with TruCal technology will adjust sensitivity without any manual intervention or calibration, unless called for by
the sensor. If the adjusted sensitivity from TruCal deviates too far from the last gas calibration sensitivity, the sensor will
recommend or, in extreme cases, require a calibration. When a calibration is recommended, the transmitter LED status
indicators slowly pulse green. Users can also enable a Calibration Alert function that will send a milli-amp signal on the
analog output to the control room when a calibration is recommended. When a calibration is required, the status LEDs will
flash yellow and the transmitter will go into a Calibration Required Fault.
With Diffusion Supervision and Calibration Alert enabled, the time between scheduled calibrations can be extended to 24
Months.
If calibration alert and/or diffusion supervision are disabled follow the calibration frequency recommendation set forth in
5.3.2 XCell Sensor with TruCal without Diffusion Supervision (CO&H2S Only).

Sensors with TruCal technology will adjust sensitivity without any manual intervention or calibration, unless called for by
the sensor. If the adjusted sensitivity from TruCal deviates too far from the last gas calibration sensitivity, the sensor will
recommend or, in extreme cases, require a calibration. When a calibration is recommended, the transmitter LED status
indicators slowly pulse green. Users can also enable a Calibration Alert function that will send a milli-amp signal on the
analog output to the control room when a calibration is recommended. When a calibration is required, the status LEDs will
flash yellow and the transmitter will go into a Calibration Required Fault. Without Diffusion Supervision, regular calibration
of the sensor must still be conducted to confirm the sensor inlet is not obstructed.
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, tracking the percent adjustment over time. Once a baseline is established, the calibration intervals can be
extended until the percent adjustment is greater than the expected accuracy of the sensor.
5.4Calibration Types: Zero vs. Span
There are two types of calibration; zero and span calibration.
The zero calibration resets the baseline level reading to zero. If the target gas is suspected to be occasionally present, it is
best to also use a zero gas cylinder during the zero calibration. If the target gas is not present in the atmosphere, an
additional calibration cylinder is not required.
The span calibration is a process that involves first zeroing the baseline reading, then applying a known amount of target
gas so that the accuracy and precision of the transmitter can be adjusted to the known value. The known concentration of
gas is called a "Span Value" because it represents the span or reach of the calibration curve from zero to that value.

The Sensor Span Value (i.e. Cal Level) in the device menu should be the same as the concentration listed on the calibration
gas cylinder.
5.5How to Zero Calibrate XCell and IR Sensors
NOTICE
If a password is enabled, you will not be able to proceed with the calibration without the password.
To abort, press the EZ touch button or apply magnet over GM logo before applying target gas.
In the event that a calibration cannot be completed, the user can acknowledge the FAIL by pressing the EZ
touch button or applying magnet to the GMI logo area until "Reset" is displayed and then release. The unit will
revert to the settings of the last successful calibration.
WARNING!
The regulator used with the zero gas cylinders should not be the same as the regulator used for the target gas. The zero gas
regulator can be contaminated with the target gas over time, and thus raise the detection baseline and make the sensor
less sensitive to the target gas.
Failure to follow this warning can result in serious personal injury or death.
If there is no target gas in the atmosphere around the sensor, using a zero gas cylinder is optional. Note that,
since air contains CO2, a zero gas cylinder is required for zeroing an IR 700 sensor. For IR700 sensors, nitrogen
is recommended as the zero gas.
To zero calibrate the sensor:
General Monitors S500072
US
5 Calibration
(1)Screw the sensor guard to the bottom of the sensor housing.
(2)Place the green calibration cap over the sensor guard inlet so that it is flush with the bottom of the sensor guard and
completely covers the sensor guard inlet.
(3)Attach the tubing to the plastic stem protruding through the green calibration cap.
(4)Screw the regulator onto the top of the zero gas cylinder.
If a password is enabled, you will need to enter it to access the menu system.
NOTICE
If the calibration cap cannot be used (such as for a remote sensor application), ambient wind conditions must be minimized
during calibration to avoid a calibration with increased sensitivity.
(5)Press EZ touch until Zero is displayed, and release.
(6)Once the screen displays Zero in Progress, turn on zero gas flow by turning knob on the regulator.
(7)Wait while the device displays Zero in Progress.
(8)Once the zero calibration is complete, a Zero PASS or FAIL is displayed.
If PASS displays, the procedure is complete.
If FAIL displays, the procedure was unsuccessful (see 6.5 Troubleshooting).
(9)Remove the zero calibration equipment from the device including the sensor guard and calibration cap.
Sensors with TruCal and have Diffusion Supervision enabled can go into Diffusion Supervision Fault if the green
Calibration Cap is left on after completing a zero calibration.
WARNING!
The green Calibration Cap must be removed from the sensor after a zero calibration. Failure to do so could restrict gas flow
to the sensor and result in erroneously low readings.
Failure to follow this warning can result in serious personal injury or death.

5.7How to Calibrate an Oxygen XCell Sensor
An oxygen span gas cylinder is not needed if the sensor is in an area that maintains ambient air conditions. Follow the
same process for XCell sensors as described in 5.6 How to Calibrate XCell Sensors. When the display prompts "Apply
Span Gas", simply allow the countdown to occur without applying gas.
If the sensor is located in an area of normally low or enriched oxygen, then a 20.8%oxygen sample must be applied.
5.8How to Calibrate an IR Sensor
A full span calibration is not required for the IR Sensors. Any degradation of the sensor's performance is associated with
slight drifts in its zero response. Restoring the sensor's zero is typically sufficient. Note that for zeroing of the IR700
sensor, zero gas is required. Air contains CO2and cannot be used. Nitrogen is recommended as the zero gas. The nitrogen
cylinder P/N is 1400262-17.
See 5.5 How to Zero Calibrate XCell and IR Sensors for zero calibration instructions.
If a full calibration of the IRSensor is required, a larger calibration cap is used and covers the entire sensor guard
during calibration. The calibration cap must be removed after completing the zeroing and/or spanning procedure.
NOTICE
If the calibration cap cannot be used (such as for a remote sensor application), ambient wind conditions must be minimized
during calibration to avoid a calibration with increased sensitivity.
5.9How to Calibrate a Passive Sensor (Catalytic Bead or MOS)
WARNING!
The sensor calibration cup must be removed from the sensor after calibration. Failure to do so could restrict gas flow to the
sensor and result in erroneously low readings.
Failure to follow this warning can result in serious personal injury or death.
If a password is enabled, you will need to enter it to access the menu system.
If the sensor is fitted with a sensor guard, calibration must be performed with the sensor guard in place.
If it is suspected that gases are present, it will be necessary to purge the sensor environment with zero air.
To calibrate sensor:
(1)Attach a regulator to the zero air cylinder (if using) and the calibration cylinder.
(2)Attach the plastic calibration cup (P/N1400152-1 or 1400154) to the bottom of the sensor if not already installed.
(3)Attach the tubing to the plastic stem protruding through the calibration cup.
(4)Push the other end of the tubing over the zero cylinder regulator. Ensure the tubing completely covers the gas outlet.
(5)Press EZ touch until Calibration is displayed, and release the touch.

If “Cal Fail” and fault code displayed, the procedure was unsuccessful. See 6.5 Troubleshooting.
5.10 XCell Catalytic Bead Failsafe
Catalytic bead sensors require the presence of oxygen in order to sense combustible gas. In the event of very large
combustible gas leaks that exceed 100 % LEL, enough oxygen can be displaced so that the sensor's response to gas is no
longer proportional to the calibration profile. The XCell catalytic bead has a locking fail safe mechanism that prevents the
false reporting of a safe condition while the % LEL concentration is still above 100 % LEL. When the gas concentration
exceeds 100 % LEL, the sensor will go into LOC over range.
To clear the LOC over rage, the user needs to acknowledge and calibrate the sensor. To acknowledge LOC over range,
press the EZ touch button or apply magnet to the GMI logo area until "Reset" is displayed and then release. This will allow
a recalibration of the sensor to clear the LOC condition.
WARNING!
Ensure that the area has been cleared of gas before acknowledging the LOC Over Range and recalibrating the sensor.
Failure to follow this warning can result in serious personal injury or death.

WARNING!
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 this warning could cause the product to fail to perform as designed and persons who
rely on this product for their safety could sustain serious personal injury or loss of life.
Repair or alteration of the S5000 Gas Monitor, beyond the scope of the maintenance procedures provided in this manual or
by anyone other than authorized MSA service personnel, could cause the product to fail to perform as designed and
persons who rely on this product for their safety could sustain serious personal injury or loss of life.
The S5000 Gas Monitor is constantly performing a self-check. When a problem is found, it displays the appropriate error
message (see6.5 Troubleshooting). When a critical error is detected within the device, the 4-20mA output signal goes to a
fault condition of 0mA, 1.25mA, 3.5mA or user defined level.
6.1IR Sensor Cleaning Procedure
The presence of particulate matter, oil films, liquid water, or the residue from water drops on the two monitor windows can
adversely affect its performance. The sensor guard is designed to prevent foreign solids or liquids from reaching the
monitor's optical system. Additionally, heating elements are incorporated into the device to prevent water condensation.
Under severe conditions, however, some material may collect on these surfaces and it may be necessary to occasionally
check and clean the windows.
While both windows are made of a highly durable material that is not easily scratched, avoid excessive pressure when
cleaning them. Clean, cotton-tipped applicators are the most convenient tool to remove material collected on the windows.
(1)Remove the sensor guard.
(2)Use a dry applicator or one moistened with distilled water to wipe the window and remove dust.
(3)Use an additional clean, dry applicator to remove any residual water.
(4)Use an applicator moistened with isopropyl alcohol to remove heavy deposits of solids, liquids or oil films. Clean the
window again with a second applicator moistened with distilled water; then, dry the window with a final applicator.
Avoid using excessive amounts of water or alcohol in the cleaning procedure, and inspect the window to ensure that
the entire surface is clean.
(5)The device will go into a “Cleaning required” fault with an analog output of 2.0mA when cleaning is needed.
The S5000 analog output may go down to 1.25mA while the optical path is blocked, and display will indicate “Beam
Block”.
While in "Beam Block" fault, the sensor will not respond to the presence of gas.
(6)When cleaning is done and the objects are removed from the sensor window, the device returns to normal operation. If
water or isopropyl alcohol was used, allow the device to operate for 15minutes to completely dry before replacing the
sensor guard continuing to monitor for combustible gas.
(7)Replace the sensor guard.
General Monitors S500077
US
6 Maintenance
When the cleaning process is complete, be sure to remove all objects from the light path. It is recommended to
check the sensor’s response to zero and calibration gas after cleaning.
WARNING!
Do not place foreign objects in the sensor's analytical region (except per the “S5000 IR Sensor Cleaning Procedure” as
described above); otherwise, the infrared beam can be partially blocked, causing the sensor to generate false readings. All
objects must be removed from the sensor's analytical region for it to function properly.
Failure to follow this warning can result in serious personal injury or death.
6.2Replacing an XCell Sensor
The only routine maintenance item is the sensor, which has a limited lifetime. The S5000 sensors with TruCal technology
will indicate when the sensor is near end of life through the Status Menu. When the Sensor Life & Health status is "Fair",
there is approximately 2month time frame to replace the sensor before it will no longer function. Actual time between “Fair”
status and sensor end of life depends on exact environmental conditions. When a TruCal sensor is no longer capable of
sensing it will go into fault and LEDs will flash yellow. It is good practice to obtain a replacement sensor before the sensor
within the unit becomes inoperative.
There is no need to open the main enclosure. Simply unscrew the sensor assembly located on the bottom of the main
assembly.
WARNING!
•Do not disassemble the sensor assembly. The sensing element inside may contain hazardous material.
•Handle the sensor carefully; the electrochemical version is a sealed unit which contains a corrosive electrolyte.
•Any leaked electrolyte that comes in contact with skin, eyes or clothes can cause burns.
•If any contact with the electrolyte does occur, immediately rinse with a large quantity of water. On contact with the
eyes, rinse thoroughly with water for 15 minutes and consult a doctor.
•Do not install a leaking sensor in the sensing head assembly.
•A leaking sensor must be disposed of in accordance with local, state and federal laws.
•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 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 this warning can result in serious personal injury or death.

6.3Clearing a Blockage
If using a Digital Sensor with Diffusion Supervision, and if the Diffusion Supervision feature has been enabled in the Sensor
Settings, the sensor will notify the user if it detects foreign material obstructing the sintered metal frit where gas would
normally enter the sensor (see Frit Location). When this condition is detected, the transmitter will go into fault and show
“Diffusion Supervision Fault” on the display. Follow these recommended steps to attempt to clear this fault:
(1)Inspect and clear the sensor inlet and frit.
(2)Inspect and clear any accessories attached to the sensor.
(3)Ensure Sensor is fully mated to the Sensor Body Assembly.
(4)Attempt to recalibrate the Sensor.
(5)Disable Diffusion Supervision or replace the Sensor.
First, with the sensor still installed, visually inspect the sensor to see if any objects are covering the gas inlet and remove
them. Example objects may include tape or the green Calibration Cap. Next, check to make sure that there is no foreign
material stuck to the frit. If any material is found, gently remove it while considering any hazards that may arise from such
an action, like the accumulation of a static charge, and taking the necessary steps to avoid them. Take care to ensure that
the frit is not damaged during the cleaning process. DO NOT use water or liquids to try to clean the frit. The frit acts like a
sponge and will retain liquids, which will keep the gas path blocked.
Figure 35 Frit Location
WARNING!
The sensor relies on the frit as a part of its Flameproof/Explosionproof approval. If the frit is damaged while attempting to
clean it, immediately remove power from the device. Ensure the area is free of a hazardous atmosphere, then follow all
steps as outlined in this manual to properly replace the sensor.
Failure to follow this warning can result in serious personal injury or death.
If no material is visible, the frit may still be blocked by a liquid which has absorbed into the frit. Once absorbed, liquids are
very difficult to remove. For these situations, relying on natural evaporation is recommended. Due to the time it can take for
liquids to evaporate sufficiently from the frit, users may want to consider swapping out the affected sensor with one that is
known to be clear. Placing absorbent material against the outer surface of the frit can help accelerate this process.
General Monitors S500080
US
If a sensor is in Diffusion Supervision Fault, the device will still allow the user to attempt to calibrate the sensor. In the rare
event that a sensor calibration is successful, but the Diffusion Supervision system continues to detect a blockage in the
gas path, the Diffusion Supervision Fault will return in approximately 24 hours. In this scenario, there is likely an
environmental factor affecting the Diffusion Supervision detection. Provided the sensor can successfully calibrate, the
sensor is still capable of detecting gas. To prevent the Diffusion Supervision Fault from reoccurring, a user can either
disable Diffusion Supervision in the Sensor Settings (see 4.2.2 Sensor Setup) or replace the sensor.
6.4Replacing a Passive Sensor (Cat Bead or MOS)
When the passive Catalytic Bead or MOS sensor is damaged or gradually losing sensitivity and eventually fails to respond
to gas adequately or fails to pass calibration, the sensor needs to be replaced.
The mounting threads of the sensor head may require lubrication. Grease must not be used. As an alternate, PTFE (Teflon)
tape may be used on sensor threads.
To replace the passive sensors:
(1)Declassify the area and make sure there is no hazardous gas/vapor present.
(2)Power down the S5000 transmitter.
(3)Unscrew the lid.
6 Maintenance
(4)Remove the User Interface Module.
(5)Refer to the sensor wiring diagram label inside the S5000 transmitter to locate the sensor connector and unplug it from
the transmitter.
(6)Unscrew the sensor head until it is totally off. Guide the sensor wires so they will not get caught by the internal parts
of the S5000 while sensor head is turning.
(7)Guide the connector and wires of the new sensor head through the conduit entry for sensor. Do not plug in the sensor
connector at this time.
(8)Screw in the new sensor head. Guide the sensor wires so they will not get caught by the internal parts of the S5000
while sensor head is turning.
(9)Verify the sensor connector wiring against the wiring diagram.
(10) Plug in the connector to the indicated header and make sure they are mated correctly.
