Install the Terminal
Before installing the terminal in a panel, review:
•
•
•
•
•
Environmental considerations
Enclosures and outdoor installation
Mounting clearances
Panel cutout dimensions
Product dimensions
Environmental Considerations
The terminals are suitable for use in an industrial environment when installed in
accordance with these instructions. Specifically, this equipment is intended for use
in clean, dry environments (Pollution Degree 2)(1) and with circuits not exceeding
Over Voltage Category II (2) (IEC 60664-1).(3)
(1)
Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a
temporary conductivity caused by condensation shall be expected.
(2)
Over Voltage Category II is the load level section of the electrical distribution system. At this level transient voltages are
controlled and do not exceed the impulse voltage capability of the product’s insulation.
(3)
Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.
Enclosures
The terminals must be mounted in a panel or enclosure to protect the internal
circuitry. The terminals meet NEMA Type 12/13 and 4X ratings only when mounted
in a panel or enclosure with the equivalent rating.
See the Outdoor Installation section for additional enclosure and certification
information on the High-Bright display modules.
When the terminal is not mounted in a panel, it is not secure or safe for operation.
You must comply with the NEMA Type 4 requirements for environmental
specifications.
Outdoor Installation
When using the High-Bright display module outdoors, important considerations in
maximizing the field life of the front bezel and display are:
• Selecting the proper enclosure
• Orientation of the terminal
Publication 2711P-IN026C-MU-P - September 2005
PanelView Plus and VersaView CE High-Bright Display Modules
11
Both ultraviolet and infrared radiation can reduce the field life of any electronic
device. While the materials used in the PanelView Plus and VersaView CE bezels
provide long field life, that life can be improved by proper installation.
Ultraviolet radiation from the sun causes all plastics to fade or yellow and become
brittle over time. Using an antiglare overlay, cat. no. 2711P-RGT12, will protect the
front of the terminal from direct exposure to UV radiation and greatly increase its
field life.
When installing the High-Bright display module in an environment where the front
of the terminal will be in direct sunlight during the hottest part of the day and the
external ambient temperature can exceed 40 °C (104 °F), use the visor kit, cat. no.
2711P-RVT12. The visor reduces the solar load on the front of the display and helps
to maintain internal temperatures within specification.
The High-Bright display module has a built in temperature sensor that automatically
reduces the backlight intensity if the temperature inside the cabinet exceeds 55 °C.
This reduces the risk of damage to the display.
The paint color, size, and power dissipated by the internal components of an
enclosure affect the temperature rise inside the cabinet. Hoffman, a Rockwell
Automation Encompass Partner, has information to assist you with enclosure
selection and heating/cooling accessories to meet the temperature requirements of
the installed equipment. See website http://www.hoffmanonline.com.
Stirring fans or active cooling may be required in high altitude and high ambient
temperature locations to keep the internal enclosure temperature below 55 °C
(131 °F). Use a heater in installations where the ambient temperature is below 0 °C
(32 °F).
The backlight of the High-Bright display generates a significant amount of heat
when set to full intensity. To minimize the amount of heat generated and extend
the life of the backlight, decrease the display intensity by using the screen saver
with a 5 to 10 minute delay.
Avoid placing the terminal on the south (north in the southern hemisphere) or west
side of the cabinet, if possible. This will reduce the heat rise due to solar loading
during the hottest part of the day.
Mount the terminal vertically to minimize solar loading on the display. Do not
mount the terminal in a sloped enclosure if it will be exposed to direct sunlight.
Publication 2711P-IN026C-MU-P - September 2005

PanelView Plus and VersaView CE High-Bright Display Modules
Mounting Clearances
Allow adequate clearance around the terminal, inside the enclosure, for adequate
ventilation. Consider heat produced by other devices in the enclosure. The ambient
temperature around the terminals must be between 0 to 55 °C (32 to 131 °F).
Minimum clearances for ventilation are:
•
•
•
•
Top clearance: 51 mm (2 in)

Functional Earth Ground
DC powered terminals have a Functional Earth (FE) terminal which you must
connect to a low impedance earth ground. This connection is required for
Electromagnetic Compliance (EMC) with the European Union (EU) EMC directive
for CE-mark conformance.
The terminals have the Functional Earth ground connection on the rear of the
display module.
The Functional Earth terminal wiring requires a minimum wire gauge.
Wire Type
Wire Gauge
Terminal Screw Torque
Stranded or solid
#14 …#10 AWG
1.13…1.36 Nm (10…12 in-lbs)
The Functional Earth terminal may be internally connected to the DC negative
(- DC) terminal within the PanelView Plus or VersaView CE terminal.
ATTENTION
A ground loop can occur when a voltage potential exists between
two separate ground points. Make sure that the terminal does not
serve as a conductive path between ground points at different
potentials.
Use a single dedicated 24V dc source (power supply) to power each terminal, such
as cat. no. 2711P-RSACDIN. Using a separate, isolated and ungrounded SELV source
to power each terminal, prevents ground loop currents from damaging the
terminals.
The terminals contain isolated and non-isolated communication ports.
For more information on wiring and grounding, refer to publication 2711P-TD001
available at www.rockwellautomation.com/literature.

Troubleshooting
Check for Adequate Power
A terminal that does not receive adequate power could cause unpredictable
behavior. Verify the power requirements in the Specifications table.
Check LED Indicators
The terminal has two LED indicators to isolate operating problems.
• COMM indicator (green) for communications
• FAULT indicator (red) for hardware faults
COMM and FAULT LEDs
When the terminal starts up, the red LED indicator should be off, except for a few
brief flashes, and the green LED should be on. If the indicators remain off, the
power supply or logic module has failed. Replace the logic module if the power is
within range; if not, replace the power supply. After a successful startup, both
indicators are off and controlled by the application running on the terminal.
The table shows the state of the indicators if the terminal powers up and stops
during startup.

UNIVERSAL REMOTE I/O LINK OVERVIEW
Universal Remote I/O Link Overview
The Allen-Bradley Universal Remote I/O Link connects the PLC and SLC
processors to remote I/O chassis and a host of intelligent devices such as
operator interfaces and ac and dc drives.
In addition to I/O, Allen-Bradley operator interfaces, ac and dc drive
systems, intelligent sensing products, Computer Numerical Controllers
(CNCs), and other devices are compatible with this link. Some products, such
as PanelView Operator Terminals, have built in "adapter" capability, while
other products, such as the 1336 drives, require optional "adapter" modules to put them on the link. Some
products are installed in the 1771 I/O chassis and communicate over the chassis backplane to a Remote I/O
Adapter, which communicates to the programmable controller's scanner. In addition, the 1784-PKTS
communication interface card lets an ISA/EISA bus PC communicate directly with Allen-Bradley remote I/O
devices.
Other companies offer products such as robotic and welding controllers, scales, and wireless modems that
are compatible with the Universal Remote I/O Link as well. In total, there are approximately 100 devices
available that can communicate on this link. By using these devices on the link, the user can speed up
communication and allow the devices to work together to help improve quality while lowering integration,
maintenance, and training costs.
For distributed processing, put a PLC-5 processor in "adapter mode" and install it in an I/O chassis where it
can monitor its own resident I/O while communicating to a supervisory PLC-5 processor over the Universal
Remote I/O Link. SLC processors can also be distributed on the link where they can control I/O while
communicating with a supervisory processor via a 1747 Direct Communication Module.
For high-speed processing applications, an extended-local I/O link is available, which provides a parallel I/O
link (the practical equivalent of processor-resident-chassis performance for I/O modules not placed in the
processor's chassis). In addition, the Allen-Bradley ControlNet network, which provides deterministic,
repeatable transfers of control data, is suitable for real-time, high-throughput applications.

Uses transceivers communicating over a single channel.
Uses standard PVC twinaxial cable (cat. no. 1770-CD) as the transmission medium.
Uses a daisy-chain connection with a maximum length of 3,048m (10,000 ft).
Operates at the data rates listed in Specifications. A 1/2-watt terminating resistor is required at each
end of the trunk line to eliminate reflections. Error checking is done using standard CRC16 checks.
Is based on the master/slave model. The controller's scanner is the master and the I/O chassis or
adapter devices are slaves. The slave only responds when told to by the master.
Provides transfer of a single unit (8, 16, or 32 bits) of I/O image data to/from each I/O module in
each I/O chassis during each I/O scan. The size of the unit depends on the I/O addressing density

selected at the I/O chassis. It can also provide block transfers of 64 words maximum to an individual
I/O module (except when used with the 1747-SN).
Lets Remote I/O Scanners connect to a maximum of 32 I/O chassis or other adapter-type devices on a
single link. Devices built to original Universal Remote I/O specifications are compatible with those
built to the new specifications. However, if any of the devices on a link are built to the original
specifications, the limit is 16 devices on a single link. In any case, for a specific scanner, the number
of adapter-type devices is limited by the I/O rack addressing capability of the scanner.

Typical Configurations
Typical configurations range from simple I/O links with PLC processors and I/O, to links with a variety of
other Allen-Bradley and third-party devices. When drives and other devices, including third-party devices
are to be included in a controller system, the Universal Remote I/O link provides the means to do that
though remote I/O adapter modules and built-in remote I/O adapters.
Using the Universal Remote I/O Link instead of direct wiring a long distance to a local I/O chassis helps
reduce installation, start-up, and maintenance costs by placing the I/O chassis closer to the sensors and
actuators. To install a Universal Remote I/O Link between buildings or in high-noise areas, such as next to
arc welders, use Allen-Bradley fiber-optic repeaters (cat. nos. 1771-AF, -AF1).

Pass-Through over Universal Remote I/O
Certain products, such as IMC™ controls, PanelView Operator Terminals, and Dataliner Message Displays,
support "Pass-Through." This capability lets you configure devices remotely over the Data Highway Plus and
Remote I/O links. Note the illustration below, it shows a PanelView configuration file, originally generated
using PanelBuilder software on a personal computer, being passed through to a PanelView Operator
Terminal.

The Model S4000C is an intelligent sensor for the detection of combustible gases and vapors.
The microprocessor-based electronics processes information at the sensor site, within an
explosion-proof housing.
A digital display provides indications and display codes that can be viewed through a window in
the cover. A red LED above the digital display signifies an ALARM condition, while a red LED
below the digital display signifies a WARN condition. Analog signal (4-20mA) and optional Dual
Redundant MODBUS communications and relays, provide remote and/or discrete indications of
the sensor’s operation.
The Model S4000C Intelligent Sensor is rated explosion-proof for use in the following
hazardous areas:
• CSA/FM: Class I, Division 1, Groups B, C, D and Class I, Zone 1, Ex d IIB+H2, T6

3.0 Installation
3.1 Receipt of Equipment
All equipment shipped by General Monitors is pre-packed in shock absorbing containers, which
provide protection against physical damage (original containers should be kept for future
shipping or storage needs).
Shipping container contents should be carefully removed and checked against the packing list.
If any damage has occurred, or there is any discrepancy in the order, please notify General
Monitors as soon as possible.
All correspondence with General Monitors must specify the equipment part number and serial
number.
The factory tests each unit; however, a complete system checkout is suggested upon initial
installation to ensure system integrity.
WARNING:
Installation and Maintenance must be carried out by suitably skilled and
competent personnel only.
3.2 Tools Required
1. “5 mm” Allen head wrench to remove enclosure lid (included with gas detector).
2. Flat-head screwdriver maximum 3/16” (5 mm) width for terminal block connections
(included with gas detector).
3. Adjustable wrench for conduit or cable gland connections (not included).
3.3 Choosing Product Locations
There are no standard rules for sensor placement, since the optimum sensor location is
different for each application. The customer must evaluate conditions at the facility to make this
determination. Generally, the Model S4000C Intelligent Sensor should be easily accessible for
calibration checks.
• The transmitter should be mounted pointing down to prevent water build-up on the sensor
head.
• The transmitter should not be placed where contaminating substances may coat it.
• Although the Model S4000C is RFI resistant, it should not be mounted in close proximity to
radio transmitters or similar equipment.
• Locate the Model S4000C where prevailing air currents contain the maximum
concentration of gas.
• Locate the Model S4000C near possible sources of gas leaks.
• Observe the Model S4000C’s temperature specification and locate the unit away from
concentrated sources of heat.
4
S4000C
• Transmitters should be mounted in an area that is as free from wind, dust, water, shock,
and vibration as possible. See Section 9.3.4 for the environmental specifications of the unit.
If the sensor cannot be located away from dust and rain, then we recommend the use of
our splash guard GM P/N 10395-1 to help protect the sensor.
Sensors may be adversely affected by prolonged exposure to certain materials. Loss of
sensitivity or corrosion may be gradual if such materials are present in low concentrations, or it
may be rapid at high concentrations. The more important materials adversely affecting sensors
are:
• Constant presence of high concentrations of Hydrogen Sulfide (H2S) gas
• Silicones (often contained in greases and aerosols)
• Halides, compounds containing Fluorine, Chlorine, Bromine and Iodine
• Heavy metals, e.g. Tetraethyl Lead
• Caustic and acidic liquids and vapors
The presence of poisons and contaminants in an area does not necessarily preclude the use of
a Model S4000C Intelligent Sensor. The feasibility of using a sensor in such areas must be
determined by an analysis of the specific factors in each application and General Monitors
should be consulted before attempting any such installation.
Sensors used in these areas usually require more frequent calibration checks than normal, and
typically have a shorter life. In many such applications, the standard two-year warranty would
not apply.
WARNING:
General Monitors discourages the painting of sensor assemblies. If the sensor
head is painted over, the gas will not be able to diffuse into the sensor. If the
assembly cover is painted over, the digital display cannot be read.
3.3.1 Remote Mounting of the Sensor from the Electronics
If it is necessary to remotely mount the sensor from the electronics and the housing, the
maximum distance can be no greater than 7600 feet, using 14 AWG wire. Sensors that are
remotely mounted must be placed in an explosion-proof rated sensor housing (GM P/N 102521), and the cable run must be contained in conduit running from the sensor housing to the
electronics. See Section 9.7 for FMRC approval requirements.
3.4 Mounting and Wiring
WARNING:
The conduit entries should be sealed per the NEC 500-3d or Canadian Electrical
Code Handbook (Part 1, Section 18-154). Additional benefit of conduit seals is
the prevention of water entering the housing through the conduit entry.
WARNING:
Unused cable entry holes must be sealed with an approved explosion-proof
stopping plug. Red caps supplied by General Monitors are for dust protection
only, and must not be left on the unit when installed.
5
S4000C
The overall and mounting dimensions for the Model S4000C (Figure 5) should be used when
making installation determinations. A complete list of the mechanical specifications can be
found in Section 9.3.2.
To prevent possible corrosion due to moisture or condensation, it is recommended that the
conduit connected to the Model S4000C housing be sealed, or contain a drain loop. Each
conduit run from a hazardous location to a non-hazardous location should be sealed so that
gases, vapors, and/or flames cannot pass beyond the seal. The purpose of seals in a Class I
hazardous location is to prevent the passage of gases, vapors, or flames from one electrical
installation to another through the conduit system.
It is not necessary to seal the Model S4000C housing to maintain its explosion-proof integrity;
however, conduit runs containing wires attached to the Model S4000C’s relay contacts must be
sealed (Section 3.5).
Information on Class I location seals can be found in the NEC, Article 501-5.
WARNING:
Acetic acid will cause damage to metal components, metal hardware, ceramic
IC’s, etc. If damage results from the use of a sealant that outgases acetic acid
(RTV silicone), the warranty will be void.
Figure 5: Outline and Mounting Dimensions
Once correctly installed, the Model S4000C requires little or no maintenance, other than
periodic calibration checks to ensure system integrity. General Monitors recommends that a
schedule be established and followed.
NOTE: The system’s full two-year warranty will be voided if customer personnel or third parties
damage the system during repair attempts.
Sensor heads exposed to the elements may require the accessory mounting threads to be
lubricated. Grease must not be used. As an alternate, PTFE (Teflon) tape may be used on
sensor accessory threads.
6
S4000C
NOTE: Do not use any material or substance on threads that contact the sensor housing.
The removal of particulate matter from sensor accessories may be done through the use of an
appropriate halogen-free solvent. Water or ethanol are examples of suitable solvents. The
accessories should be thoroughly dried with compressed air, if necessary, before refitting to the
sensor body.
3.5 Terminal Connections
The terminal blocks (TB) are located inside the housing and can by accessed by removing the
cover. A label on the inside of the housing cover provides details of all the terminal
connections.
3.5.1 Terminal Block TB1 – Sensor Connections
TB1 contains the three sensor connections, white (W), black (B), and red (R). Remove the
display board by loosening the two captive screws on the board and lifting it straight up.
Connect the color-coded wires from the combustible sensor to the matching colored terminals
on TB1. The label on the inside of the cover can serve as a guide. Replace the display board

3.5.6 European Union (EU) Approved Applications
Interconnecting cables must have an overall screen or screen and armor. Cables BS5308 Part
2, Type 2, or equivalent are suitable. Note that the terms ‘screen’ and ‘shield’ are equivalent for
the purpose of this manual. The cable armor must be terminated in a suitable cable gland, at
the detector, to ensure a positive electrical connection.
3.5.7 Cable Termination in the Non-Hazardous Area
• The cable armor must be connected to safety earth in the safe area.
• The cable screen (drain wire) must be connected to an instrument earth in the safe area.
• The power supply OV return must be connected to an instrument earth in the safe area.
• The interconnecting cables should be segregated from power and other noisy cables.
Avoid proximity to cables associated with radio transmitters, welders, switch mode power
supplies, inverters, battery chargers, ignition systems, generators, switch gear, arc lights
and other high frequency or high power switching process equipment. In general, maintain
separation of at least 1 meter between instrument and other cables. Greater separations
are required where long parallel cable runs are unavoidable. Avoid running instrument
cable trenches close to lightning conductor earthing pits.
• Complete all cable insulation testing before connecting the cable at either end.
WARNING:
Under NO circumstances should equipment be connected or disconnected when
under power. This is contrary to hazardous area regulations and may lead to
serious damage to the equipment. Equipment damaged in this manner is not
covered under warranty.
11
S4000C
3.6 Maintaining the X/P Integrity
The Model S4000C Intelligent Sensor is rated explosion-proof for use in the following
hazardous locations:
• CSA/FM: Class I, Division 1, Groups B, C, D and Class I, Zone 1, Ex d IIB+H2, T6
• ATEX: II 2 G EEx d IIB T5 (Tamb=-40°C to +70°C) EN 61779-1
Some of the factors that influence the explosion-proof integrity of the Model S4000C housing
are:
• Strength of the enclosure material
• Thickness of the enclosure walls
• Flame path between the housing and cover
• Flame path of threaded joints
The acceptable limits for explosion-proof housings that are used in Class I hazardous locations
are defined in CSA Standard C22.2 No.30-M1986, FM 3615, and EN50014.
Anytime the cover of the Model S4000C housing is removed, or the cover bolts are loosened,
the flame path between the lid and the housing is affected. If power is to be left on while
removing the cover or loosening the cover bolts on the Model S4000C, it will be necessary to
declassify the area.
When replacing the cover, the gap between the lid and the housing should be less than .0015
inch (.038 mm). Make sure that the flame-path is clear of dirt and debris before replacing the
cover. This can be verified by tightening the cover bolts to a torque setting of 50 inch-pounds or
by using a feeler gauge to ensure the gap between the cover and the housing is less than
.0015 inch (.038 mm).
There are four entry holes, one each on the left and right sides, and two on the bottom of the
Model S4000C housing. These holes are dedicated for the sensor, the reset switch and
conduit. Each hole is tapped for ¾” NPT threads. If a particular entry hole is not used, it must
be plugged during operation in the field. The factory installs plugs in the unused entry holes,
except one. A red plastic cap is placed into the remaining hole and must be removed before
conduit can be attached to the housing.
The Model S4000C will have the following items placed in the three remaining entry holes, at
the factory:
• A sensor, if present (otherwise a red plastic cap)
• A reset switch, if present (otherwise an aluminum housing plug - optional)
• An aluminum-housing plug
The sensor, reset switch, and aluminum-housing plug have seven threads. Each of these
components is screwed into the housing using five to seven turns. If it becomes necessary to
replace the sensor, reset switch and/or the aluminum-housing plug, the user must use five to
seven turns to ensure the explosion-proof integrity of the housing is maintained.

S4000C
4.0 Operation
4.1 Start-Up Checklist
Prior to starting the system, verify the following:
1. Inhibit any external devices, such as Trip Amplifiers, PLC’s, or DCS systems.
2. Verify that the optional settings are set for the desired configuration.
3. Verify that the unit is properly mounted. Ensure the conduit/cable gland entries are
pointed downward.
4. Verify that the signal wiring is correct.
5. Verify that the power supply is connected properly. The Model S4000C is powered by
+24VDC (20 to 36 VDC voltage range). The detector will output a low voltage (F6) fault
at 18.5 VDC or below.
6. Make sure the lid is securely installed or the area has been declassified.
4.2 Start-Up
Before applying power to the system for the first time, all wiring connections should be checked
for correctness and the housing cover replaced. Upon first power-up the sensor may take up to
fifteen minutes to stabilize.
At the initial application of power, the unit will test all of the LED segments by displaying “88.8”.
The software revision letter will then be displayed for a few seconds. The unit will then enter a
fifty second Start-Up mode. During this period, the display will read “SU”. The unit will then
enter Operational Mode, and the current gas concentration at the sensor will be displayed. For
details of Calibrating and Gas Checking the unit, see Sections 4.5 and 4.6.
4.3 Relay Reset
If the Warn and Alarm relays are configured as latching, they must be manually reset, after an
alarm occurs. This can be accomplished by three different methods:
1. The relays can be reset via the MODBUS Interface (Section 8.8.16).
2. The relays can be reset via the magnetic switch using a magnet. Place the magnet
over the GM Logo on the cover of the unit. After three seconds, the display will show
“rSt”. Remove the magnet at this time and the relays will be reset (Figure 10).
13
S4000C
Figure 10: Relay Reset
3. The relays can be reset via the Remote Reset input terminals on TB2. Connect a
normally open switch between terminal TB2-7 and TB2-8. Closing the switch
momentarily will reset the relays. General Monitors explosion-proof switch, P/N 300511, can be used for this purpose. See Section 9.6 for ordering instructions.
NOTE: Red LED’s above and below the digital display indicate that the Alarm and Warn relays
are active. Latching relays can only be reset if the gas concentration has fallen below
the respective relay set point.
4.4 User Selectable Options
The Model S4000C Intelligent Sensor includes many selectable options to provide the user with
the most flexible combustible gas detector possible. These options include Adjustable
Calibration Level, Warn and Alarm Relay Set Points and Configuration, and MODBUS
Communications Settings. These allow the unit to operate with a wide variety of PLC and DCS
Systems. The following sections explain the available options and how they can be customized.

4.5 Gas Check Mode
The sensor response can be checked without activating external alarms by placing the Model
S4000C in Gas Check Mode. In this Mode, the alarm relays are inhibited and the analog output
is fixed at 1.5mA.
4.5.1 Procedure for Checking the Calibration
Place the magnet over the GM Logo on the cover of the Model S4000C. Remove the magnet
when a flashing pair of bars, “- -” (Figure 12), appears on the display (about ten seconds).
Apply the test gas to the sensor; the value of the gas concentration will be indicated by the
flashing display, and should stabilize in one to two minutes.
Figure 12: Calibration Check
When the reading has stabilized and the test is complete, remove the gas and the unit will
return to normal operation when the concentration drops below 5% full-scale.
If, after the reading has stabilized, the sensor is to be calibrated, simply apply the magnet to the
GM Logo on the housing cover, and the unit will enter Calibration Mode.
Gas Check Mode can be aborted if gas has not been applied to the sensor. Simply reapply the
magnet to the GM Logo on the cover and the unit will return to normal operation.
NOTE: The test gas concentration must be at least 10% full-scale before the unit will complete
the gas check sequence. If the Model S4000C is placed in the Gas Check Mode and
no gas is applied for six minutes, the unit will revert to a Fault condition. Re-applying
the magnet over the GM Logo will return the unit to normal operation.
4.6 Calibration
General Monitors recommends that the Model S4000C Intelligent Sensor be calibrated one
hour after start-up, and that the calibration be checked at least every ninety (90) days to ensure
system integrity. Frequent calibration checks ensure the integrity of the life protecting
equipment.
The above statement is not intended to discourage the customer from checking calibration
more frequently. Frequent calibration checks are recommended for environments that have
problems, such as mud collecting on the sensor head, sensors accidentally being painted over,
etc.
18
S4000C
General Monitors recommends that a calibration schedule be established and followed. A
logbook should also be kept, showing calibration dates and dates of sensor replacement.
4.6.1 Calibration Procedure
If it is suspected that gases are present, it will be necessary to purge the sensor environment
with Zero Air. If Zero Air is not available, cover the sensor for about thirty seconds before
applying the calibration gas. Zero Air is air that is hydrocarbon free.
Entering Calibration Mode automatically disables the alarm circuits by sending a 1.5mA output
signal and disabling the Warn and Alarm relays, if present. This will also prevent activation of
the remote relay contacts when using a General Monitors Readout/Relay Display Module with
the Model S4000C.
To enter Calibration Mode, place the magnet over the GM Logo on the cover of the unit (Figure
4) and hold it there until “AC” (Figure 13) appears on the display (about ten seconds). The
display will flash the remaining sensor life (Section 4.6.4) for about ten seconds, while the unit
acquires the zero reading. Ensure that the sensor is seeing clean air during this time.
Figure 13: Automatic Calibration Mode
Apply the calibration gas concentration to the sensor (usually 50% LEL of the desired gas). The
display will change from “AC” (Automatic Calibration) to “CP” (Calibration in Progress),
indicating that the sensor is responding to the calibration gas (Figure 14).
Figure 14: Calibration In Progress Mode
After one or two minutes, the display will change from “CP” to “CC” (Figure 15), indicating that
the calibration is complete.
Figure 15: Calibration Complete Mode
Remove the gas and wait for the unit to return to normal operation. The display will indicate a
few percent full-scale and then drop to “0”.
19
S4000C
The unit is now calibrated and the new ZERO and SPAN values have been stored in the nonvolatile memory (EEPROM).
4.6.2 Aborting Calibration
If calibration is to be aborted, and gas has not been applied, wait ninety seconds and reapply
the magnet. The unit will return to normal operation with the previous calibration values
unchanged.
NOTE: Once gas has been applied, it is not possible to abort a calibration.
If the Model S4000C is placed in the Calibration Mode and no gas is applied for six minutes,
the unit will revert to a Fault condition. Re-applying the magnet over the GM Logo will return the
unit to operational mode with the previous calibration values unchanged.
4.6.3 Adjustable Calibration Level
The Model S4000C provides
LEL to 90% LEL. The default
gas already available at their
perform cross-calibration to a
Mode.
the user with the ability to adjust the calibration level from 25%
value from the factory is 50% LEL. This allows the user to utilize
installation, that is not 50% LEL of the gas being detected, or to
similar gas. Adjusting the Calibration Level is performed in Setup
NOTE: %LEL to %Volume Fraction is converted by using 325 Guide to Fire Hazard properties
of Flammable Liquids, Gases, and Volatile Solids. For example, 100% LEL CH4 is
shown in NFPA to be 5% Volume, Calibration is at 50% LEL or 2.5% Volume.
WARNING:
General Monitors recommends calibrating the Model S4000C with 50% LEL of
the gas being detected. This provides the most accurate calibration, since the
Model S4000C is optimized for this concentration. The accuracy of the calibration
may be reduced by using a different calibration level, and this inaccuracy will
increase as the calibration level varies from 50% LEL.
4.6.4 Remaining Sensor Life
The Model S4000C Intelligent Sensor provides an estimate of remaining sensor life, in percent
remaining, to provide the user with an early warning of the need for sensor replacement. The
remaining sensor life is updated each time the unit is calibrated. The current remaining sensor
life estimate is displayed during the zeroing portion of a calibration sequence. It can also be
read via the MODBUS interface (Section 8.8.17).
NOTE: The remaining sensor life provides an estimate of the amount of life remaining for the
sensor. Many factors including, environmental conditions, poisons, etc can affect this
estimate. It should be used only as an estimate for preventive maintenance and logistic
purposes.
4.6.5 Initializing the Remaining Sensor Life
The remaining sensor life estimate must be initialized each time a new Hydrocarbon Sensor is
installed. The initialization should be done during the first calibration of a newly installed sensor.
After the sensor has been on power for a minimum of one hour, enter calibration mode as
20
S4000C
described in Section 4.6.1. While the display is flashing the remaining sensor life estimate
during zeroing, apply the magnet to the GM Logo on the cover. The flashing number will
change to “100”, indicating the sensor has 100% of remaining sensor life. Complete the
calibration per Section 4.6.1.
4.7 Calibration Equipment
4.7.1 Portable Purge Calibrator
The portable purge calibrator is a compact, accurate and safe system containing a nonexplosive gas concentration. The lecture bottle is filled with a standard 50% LEL mixture of
gas/air. Using a known gas/air mixture reduces the likelihood of error in field calibration. The
hose and cup adapter included, allow for quick calibrations and gas checks.
Pre-mixed calibration gases at approximately 50% LEL are available, in lecture bottles, at 1200 psi,
8.3 MPa maximum pressure.
Hydrogen
H2
Methane
CH4
Propane
C3H8
Please specify the gas upon ordering. Spare bottles containing these gases may be ordered.
Methane and Hydrogen lecture bottles may be returned to General Monitors for refilling.

6.0 Troubleshooting
CAUTION:
Component level repair must be undertaken either by General Monitors’
personnel, or by competent authorized service engineers. SMT PCB repair shall
only be performed at a General Monitors facility. Failure to comply with this
requirement will invalidate the warranty.
Be sure to inhibit or disconnect external alarm wiring before making any check, which might
send the unit into alarm, if an alarm condition will cause a problem.
6.1 Fault Codes & Their Remedies
The Model S4000C has self-diagnostics incorporated into the microprocessor’s program. If a
Fault is detected, the output signal will drop to 0mA, the Fault relay will de-energize and a Fault
code will be displayed. The output signal will inform a remote display module that the Model
S4000C is in the Fault Mode. The display will indicate a Fault code that can be viewed at the
sensor site.
There are nine Fault conditions that are monitored by the microprocessor, as follows:
6.1.1 F2 Failed to Complete Calibration
This Fault will occur if the unit is placed in the calibration mode and no gas has been applied
within six minutes, or if gas has been left on for more than six minutes.
ACTION – Remove gas, if present. Apply the magnet to the GM Logo on the cover to clear the
fault. Attempt to calibrate.
6.1.2 F3 EEPROM Checksum Error
This fault indicates that the contents of the Model S4000C’s program memory have changed.
This usually occurs, when powering the unit up after a lightning strike or large voltage transient
on the power or signal lines to the unit.
ACTION - The unit must be returned to the factory or authorized service center for repair.
6.1.3 F4 Sensor Error
This fault indicates that either one of the remote sensor leads is open or shorted, or that the
sensor has drifted greater than –10%.
ACTION - Check the integrity of all sensor connections, and ensure that the cable from the
Model S4000C to the remote sensor is not damaged. If all sensor leads are connected
properly, attempt to re-calibrate the unit. If calibration fails, replace the sensor and re-calibrate.
6.1.4 F5 Unused
23
S4000C
6.1.5 F6 Low Supply Voltage
This fault occurs if the supply voltage at the S4000C drops below +18.5VDC.
ACTION - Ensure that the supply voltage is at least +20VDC at the Model S4000C.
NOTE: With long supply leads, a considerable voltage drop may occur, due to the electrical
resistance of the leads. The maximum cable resistance, which the Model S4000C can
tolerate, is dependent on the supply voltage: a maximum of 20 ohms per conductor (40
ohms loop), at +24VDC minimum, or a maximum of 10 ohms per conductor (20 ohms
loop), at +20VDC minimum.
6.1.6 F7 EEPROM Verification Failure
This fault occurs when an attempt to verify the setup/calibration parameters just written to the
EEPROM memory fails.
ACTION - The unit must be returned to the factory or authorized service center for repair.
6.1.7 F8 Failure to Complete Setup
This fault occurs if the unit is left in setup mode for more than 6 minutes.
ACTION - Exit setup mode. Enter setup mode again if it is necessary to change any user
selectable options.
6.1.8 F9 Gas Check Period Exceeded
If the Model S4000C is left in the gas check mode for more than six minutes without a Test Gas
being applied or if test gas is left on the gas check mode for more than 6 minutes, this fault will
occur.
ACTION - Place the magnet over the GM Logo on the cover to return the unit to normal
operation.
NOTE: Anytime a sensor is replaced, the unit should be disconnected from all alarms, as the
unit may go upscale upon power-up.
6.1.9 F10 Switch Error
This fault occurs if the remote reset, remote calibrate, or the magnetic switch are closed for
more than two minutes.
ACTION – Check the wiring on the remote reset and remote calibrate switches. Once the short
circuit is cleared, the unit will return to normal operation. If the magnetic switch is shorted, the
unit must be returned to the factory or authorized service center for service.

8.6 Exception Responses and Exception Codes
8.6.1 Exception Response
In a normal communications query and response, the master device sends a query to the
S4000C and the S4000C receives the query without a communications error and handles the
query normally within the master device’s allowable timeout. The S4000C then returns a normal
response to the master. An abnormal communications query produces one of four possible
events:
1. If the S4000C does not receive the query due to a communications error, then no
response is returned from the S4000C and the master device will eventually process a
timeout condition for the query.
2. If the S4000C receives the query, but detects a communication error (CRC, etc.), then
no response is returned from the S4000C and the master device will eventually
process a timeout condition for the query.
27
S4000C
3. If the S4000C receives the query without a communications error, but cannot process
the response to the master within the master’s timeout setting, then no response is
returned from the S4000C. The master device will eventually process a timeout
condition for the query. In order to prevent this condition from occurring, the
maximum response time for the S4000C is 200 milliseconds. Therefore the
master’s timeout setting should be set to 200 milliseconds or greater.
4. If the S4000C receives the query without a communications error, but cannot process it
due to reading or writing to a non-existent S4000C command register, then the S4000C
will return an exception response message informing the master of the error.

8.6.2 Exception Code
Exception Code Field: In a normal response, the S4000C returns data and status in the data
field, which was requested in the query from the master. In an exception response, the S4000C
returns an exception code in the data field, which describes the S4000C condition that caused
the exception. Below is a list of exception codes that are supported by the S4000C:

Description
The function code received in the query is not an
allowable action for the S4000C.
The data address received in the query is not an
allowable address for the S4000C.
A value contained in the query data field is not an
allowable value for the S4000C.
An unrecoverable error occurred while the
S4000C was attempting to perform the requested
action.
The S4000C has accepted the request and is
processing it, but a long duration of time will be
required to do so. This response is returned to
prevent a timeout error from occurring in the
master.
The S4000C is engaged in processing a longduration program command. The master should
retransmit the message later when the slave is
free.

9.1 Warranty
General Monitors warrants the Model S4000C to be free from defects in workmanship or
material under normal use and service within two years from the date of shipment.
General Monitors will repair or replace without charge any such equipment found to be
defective during the warranty period. Full determination of the nature of, and responsibility for,
defective or damaged equipment will be made by General Monitors’ personnel.
Defective or damaged equipment must be shipped to the General Monitors’ plant, or
representative from which the original shipment was made. In all cases, this warranty is limited
to the cost of the equipment supplied by General Monitors. The customer will assume all
liability for the misuse of this equipment by its employees, or other personnel.
All warranties are contingent upon proper use in the application for which the product was
intended and do not cover products which have been modified or repaired without General
Monitors’ approval or which have been subjected to neglect, accident, improper installation or
application, or on which the original identification marks have been removed or altered.
Except for the express warranty stated above, General Monitors disclaims all warranties with
regard to the products sold, including all implied warranties of merchantability and fitness, and
the express warranties stated herein are in lieu of all obligations or liabilities on the part of
General Monitors for damages including, but not limited to, consequential damages arising out
of, or in connection with, the performance of the product.
9.2 Principle of Operation
Many gases and vapors are combustible. General Monitors uses a low temperature catalytic
bead to detect the presence of combustible gases and vapors. The catalytic bead converts the
combustible materials to heat. A change in heat is then converted to a change in resistance,
which can be measured.
Taking a matched pair of catalytic beads and coating one so that it does not respond to the
presence of combustible gases can compare the change in resistance between the two beads.
The bead that is coated is called the reference bead and the other is called the active bead.
Because the beads are a matched pair, they will respond equally to changes in ambient
temperature, humidity, and pressure. This makes the sensor virtually immune to changing
environmental conditions.
By connecting one end of each catalytic bead together, a series circuit is formed. This circuit is
supplied with a constant current. The voltage drop across each of the beads will be identical in
the absence of combustible gases. As combustible material is converted to heat, the resistance
of the active bead increases, causing the voltage drop across each bead to be different. This
difference is proportional to the amount of combustible gas that is present.
The voltage from the sensor is amplified and fed to an Analog to Digital (A/D) converter and
then made available to the microprocessor. The baseline and the gain for the amplifier are set
using digital potentiometers. They are adjusted by the microprocessor during calibration.

9.7 FMRC Approval
Factory Mutual Research Corporation
1151 Boston-Providence Turnpike
Norwood, Massachusetts 02062
Approval of the transmitter does not include, or imply, approval of apparatus to which the
transmitter may be connected and which processes the electronic signal for the eventual end
use. In order to maintain FMRC approved system, the control instrument, to which the subject
instrument is connected, must be FMRC approved.
The following sensors have been FMRC approved for use with the Model S4000C:
• 10001-1 Aluminum Body General Purpose Combustible Gas Sensor
• 10058-1 Stainless Steel Body General Purpose Combustible Gas Sensor
The following apparatus have been FMRC approved (although they have not been verified as
part of a Model S4000C system):
• Model DC110 Eight Channel Readout/Relay Display Module
• Model DC130 Dual Channel Readout/Relay Display Module
Factory Mutual Research Corporation has tested the Model S4000C according to the criteria
listed under the FMRC Approval Standards for Combustible Gas Detectors, Class Numbers
6310 & 6320.
FMRC has tested the Model S4000C using the specifications listed in Section 9.2. This permits
an operating temperature of -40°F to +167°F (-40°C to +75°C), a general purpose sensor
(10001-1 or 10058-1) attached to the housing (i.e. not remote), calibration performed with a
General Monitors’ Portable Purge Calibrator using 50% LEL gas (Methane, Hydrogen,
Butadiene, Butane, Ethane or Propane) and the procedure listed in Section 4.5. The conduit
containing wires connected to the relay contacts must be sealed. If the non-latching relay
option has been selected from the relay options, the user must provide alternate means of
latching the relay output.

Acetic acid will cause damage to metal components, metal hardware, ceramic
IC’s, etc. If damage results from the use of a sealant that outgases acetic acid
(RTV silicone), the warranty will be void.
Figure 1: S4000T Outline and Mounting Dimensions
Terminal Connections
The terminal blocks (TB) are located inside the housing and can by accessed by removing the
cover. A label on the inside of the housing cover provides details of all the terminal
connections.
It is recommended that a three-wire (red, black, white) shielded cable be used for making
power and output signal connections on the Model S4000C. The Spring Type terminal block
accepts 14 AWG to 20 AWG and the Screw Type terminal block accepts 12 AWG to 18 AWG
stranded or solid wire. Each wire should be stripped before wiring the Model S4000C Intelligent
Sensor. To connect wiring to the Spring Type terminal block, insert a screwdriver into the

3.0 Installation
3.1 Receipt of Equipment
All equipment shipped by General Monitors is pre-packed in shock absorbing containers, which
provide protection against physical damage (original containers should be kept for future
shipping or storage needs).
Shipping container contents should be carefully removed and checked against the packing list.
If any damage has occurred or there is any discrepancy in the order, please notify General
Monitors as soon as possible.
All correspondence with General Monitors must specify the equipment part number and serial
number.
The factory tests each unit; however, a complete system checkout is suggested upon initial
installation to ensure system integrity.
WARNING:
Installation and maintenance must be carried out by suitably skilled and
competent personnel only.
WARNING:
The Model S4000T Intelligent Sensor contains components, which can be
damaged by static electricity. Special care must be taken when wiring the system
to ensure that only the connection points are touched.
3.2 Tools Required
1. “5mm” Allen head wrench to remove enclosure lid (included with gas detector).
2. Flat-head screwdriver maximum 3/16 in (5 mm) width for terminal block connections
(included with gas detector).
3. Adjustable wrench for conduit or cable gland connections (not included).
3.3 Choosing Product Locations
There are no standard rules for sensor placement, since the optimum sensor location is
different for each application. The customer must evaluate conditions at the facility to make this
determination. Generally, the Model S4000T Intelligent Sensor should be easily accessible for
calibration checks.
•
The transmitter should be mounted pointing down to prevent water build-up on the
sensor head.
•
The transmitter should not be placed where contaminating substances may coat it.
•
Although the Model S4000T is RFI resistant, it should not be mounted in close
proximity to radio transmitters or similar equipment.
•
Locate the Model S4000T where prevailing air currents contain the maximum
concentration of gas.
14
S4000T
•
Locate the Model S4000T near possible sources of gas leaks.
•
Observe the Model S4000T’s temperature specification and locate the unit away from
concentrated sources of heat.
•
Transmitters should be mounted in an area that is as free from wind, dust, water,
shock, and vibration as possible. See Section 9.3.4 for the environmental specifications
of the unit. If dust and rain cannot be avoided, we recommend the use of our splash
guard (GM P/N 10395-1).
Sensors may be adversely affected by prolonged exposure to certain materials. Loss of
sensitivity or corrosion may be gradual if such materials are present in low concentrations, or it
may be rapid at high concentrations. The more important materials adversely affecting sensors
are:
•
Silicones (often contained in greases and aerosols)
•
Halides: compounds containing Fluorine, Chlorine, Bromine and Iodine
•
Heavy metals, e.g. Tetraethyl Lead
•
Caustic and Acidic liquids and vapors
•
Glycol
The presence of contaminants in an area does not necessarily preclude the use of a Model
S4000T Intelligent Sensor. The feasibility of using a sensor in such areas must be determined
by an analysis of the specific factors in each application, and General Monitors should be
consulted before attempting any such installation.
Sensors used in these areas usually require more frequent calibration checks than normal, and
typically have a shorter life. In many such applications the standard two-year warranty would
not apply.
IMPORTANT: Each H2S Sensor is shipped with a red plastic cap fitted over the sensor head.
Inside the cap is a desiccant. DO NOT remove this cap until you are ready to
power the system. SAVE the cap and RE-CAP the sensor anytime the system
power is off for more than one hour.
WARNING:
General Monitors discourages the painting of sensor assemblies. If the sensor
head is painted over, the gas will not be able to diffuse into the sensor. If the
assembly cover is painted over, the digital display cannot be read.
3.3.1 Remote Mounting of the Sensor from the Electronics
If it is necessary to remotely mount the sensor from the electronics and the housing, the
maximum distance can be no greater than 3700 feet (1125) meters, using 14 AWG wire.
Sensors that are remotely mounted, must be placed in an explosion-proof rated sensor housing
(GM P/N 10252-1), and the cable run must be contained in a conduit running from the sensor
housing to the electronics. See Section 9.6, for FMRC approval requirements.
15
S4000T
3.4 Mounting and Wiring
WARNING:
The conduit entries should be sealed per the NEC 500-3d, or Canadian Electrical
Code Handbook (Part 1, Section 18-154). Additional benefit of conduit seals is
the prevention of water entering the housing through the conduit entry.
WARNING:
Unused cable entry holes must be sealed with an approved explosion-proof plug.
Red caps supplied by General Monitors are for dust protection only and must not
be left on the unit when installed.
The overall and mounting dimensions for the Model S4000T (Figure 5) should be used when
making installation determinations. A complete list of the mechanical specifications can be
found in Section 9.3.2.
To prevent possible corrosion due to moisture or condensation, it is recommended that the
conduit connected to the Model S4000T housing be sealed, or contain a drain loop.
Each conduit run from a hazardous location to a non-hazardous location should be sealed so
that gases, vapors, and/or flames cannot pass beyond the seal. The purpose of seals in a
Class I hazardous location, is to prevent the passage of gases, vapors, or flames from one
electrical installation to another, through the conduit system. It is not necessary to seal the
Model S4000T housing to maintain its explosion-proof integrity; however, conduit runs
containing wires attached to the Model S4000T’s relay contacts must be sealed (Section 3.5).
Information on Class I location seals can be found in the NEC, Article 501-5.
Figure 5: S4000T Outline and Mounting Dimensions
WARNING:
Acetic acid will cause damage to metal components, metal hardware, ceramic
IC’s, etc. If damage results from the use of a sealant that outgases acetic acid
(RTV silicone), the warranty will be void.
16
S4000T
Once correctly installed, the Model S4000T requires little or no maintenance, other than
periodic calibration checks to ensure system integrity. General Monitors recommends that a
schedule be established and followed.
NOTE: The system’s full two-year warranty will be voided if customer personnel or third parties
damage the system during repair attempts.
Sensor heads exposed to the elements may require the accessory mounting threads to be
lubricated. Grease must not be used. As an alternate, PTFE (Teflon) tape may be used on
sensor accessory threads.
NOTE: Do not use any material or substance on threads that contact the sensor housing.
The removal of particulate matter from sensor accessories may be done through the use of an
appropriate halogen-free solvent. Water and/or ethanol are examples of suitable solvents. The
accessories should be thoroughly dried, with compressed air if necessary, before refitting to the
sensor body.
3.5 Terminal Connections
The terminal blocks (TB) are located inside of the housing and can by accessed by removing
the cover. A label on the inside of the housing cover provides details of all the terminal
connections.
3.5.1 Terminal Block TB1 – Sensor Connections
TB1 contains the four sensor connections, white (W), black (B), red (R) and green (G). Remove
the display board by loosening the two captive screws on the board and lifting it straight up.
Connect the color-coded wires from the sensor to the matching colored terminals on TB1. The
label on the inside of the cover can serve as a guide. Replace the display board, by pressing it
into place, and tightening the two captive screws.
WARNING:
Do not connect +24VDC to TB1. Damage to the electronics or sensor may result.

3.5.6 European Union (EU) Approved Applications
Interconnecting cables must have an overall screen, or screen and armor. Cables BS5308 Part
2, Type 2, or equivalent are suitable.
NOTE: The terms ‘screen’ and ‘shield’ are equivalent for the purpose of this manual. The
cable armor must be terminated in a suitable cable gland at the detector, to ensure a
positive electrical connection.
3.5.7 Cable termination in the non-hazardous area
•
The cable armor must be connected to safety earth in the safe area.
•
The cable screen (drain wire) must be connected to an instrument earth in the safe
area.
21
S4000T
•
The power supply OV return must be connected to an instrument earth in the safe
area.
•
The interconnecting cables should be segregated from power and other noisy cables.
Avoid proximity to cables associated with radio transmitters, welders, switch mode
power supplies, inverters, battery chargers, ignition systems, generators, switch gear,
arc lights and other high frequency or high power switching process equipment. In
general, maintain separation of at least 1 meter between instrument and other cables.
Greater separations are required where long parallel cable runs are unavoidable. Avoid
running instrument cable trenches close to lightning conductor earthing pits.
•
Complete all cable insulation testing before connecting the cable at either end.
WARNING:
Under NO circumstances should equipment be connected or disconnected when
under power. This is contrary to hazardous area regulations and may lead to
serious damage to the equipment. Equipment damaged in this manner is not
covered under warranty.
3.6 Maintaining the X/P Integrity
The Model S4000T is rated explosion-proof for the following hazardous locations:
•
CSA/FM: Class I, Division 1, Groups B, C, D and Class I, Zone 1, Ex d IIB+H2, T6 and
•
ATEX: EEx d IIB T6 (Tamb=-40°C to +40°C)
Some of the factors that influence the explosion-proof integrity of the Model S4000T housing
are:
•
Strength of the enclosure material
•
Thickness of the enclosure walls
•
Flame path between the housing and cover
•
Flame path of threaded joints
The acceptable limits for explosion-proof housings that are used in Class I hazardous locations
are defined in CSA Standard C22.2 No.30-M1986, FM 3615 and EN50014.
Anytime the cover of the Model S4000T housing is removed or the cover bolts are loosened,
the flame path between the lid and the housing is affected. If power is to be left on while
removing the cover or loosening the cover bolts on the Model S4000T, it will be necessary to
declassify the area.
When replacing the cover, the gap between the lid and the housing should be less than .0015
inch (.038 mm). Make sure that the flame path is clear of dirt and debris before replacing the
cover. This can be verified by tightening the cover bolts to a torque setting of 50 inch-pounds or
by using a feeler gauge to ensure the gap between the cover and the housing is less than
.0015 inch (.038 mm).
There are four entry holes, one each on the left and right sides, and two on the bottom of the
Model S4000T housing. These holes are dedicated for the sensor, the reset switch and conduit.
Each hole is tapped for ¾” NPT threads. If a particular entry hole is not used, it must be
22
S4000T
plugged during operation in the field. The factory installs plugs in the unused entry holes,
except one. A red plastic cap is placed into the remaining hole and must be removed before
conduit can be attached to the housing.
The Model S4000T will have the following items placed in the three remaining entry holes, at
the factory:
•
A sensor, if present (otherwise a red plastic cap)
•
A reset switch, if present (otherwise an aluminum housing plug – optional)
•
An aluminum housing plug
The sensor, reset switch and aluminum-housing plug have seven threads. Each of these
components is screwed into the housing using five to seven turns. If it becomes necessary to
replace the sensor, reset switch and/or the aluminum-housing plug, the user must use five to
seven turns to ensure the explosion-proof integrity of the housing is maintained.
23
S4000T
4.0 Operation
4.1 Start-Up Checklist
Prior to starting the system, verify the following:
1. Inhibit any external devices, such as Trip Amplifiers, PLC’s, or DCS systems.
2. Verify that the optional settings are set for the desired configuration.
3. Verify that the unit is properly mounted. Ensure the conduit/cable gland entries are
pointed downward.
4. Verify that the signal wiring is correct.
5. Verify that the power supply is connected properly. The Model S4000T is powered by
+24VDC (20 to 36 VDC voltage range). The detector will output a low voltage fault (F6)
at 18.5 VDC or below.
6. Make sure the lid is securely installed or the area has been de-classified.
4.2 Start-Up
Before applying power to the system for the first time, all wiring connections should be checked
for correctness and the housing cover replaced. Upon first power-up, the sensor may take up to
fifteen minutes to stabilize.
At the initial application of power, the unit will test all of the LED segments by displaying “88.8”.
The software revision letter will then be displayed for a few seconds. The unit will then enter
Operational Mode and the current gas concentration at the sensor will be displayed. For details
of Calibrating and Gas Checking the unit, see Sections 4.5 and 4.6.
4.3 Relay Reset
If the Warn and Alarm relays are configured as latching, they must be manually reset, after an
alarm occurs. This can be accomplished by three different methods:
1. The relays can be reset via the MODBUS Interface (Section 8.8.15).
2. The relays can be reset via the magnetic switch using a magnet. Place the magnet
over the GM Logo on the cover of the unit. After three seconds the display will show
“rSt”. Remove the magnet at this time and the relays will be reset (Figure 10).
24
S4000T
Figure 10: Relay Reset
3. The relays can be reset via the Remote Reset input terminals on TB2. Connect a
normally open switch between terminal TB2-7 and TB2-8. Closing the switch
momentarily will reset the relays. General Monitors explosion-proof switch, P/N 300511 can be used for this purpose. See Section 9.5 for ordering instructions.
NOTE: Red LED’s above and below the digital display indicate that the Alarm and Warn relays
are active. Latching relays can only be reset if the gas concentration has fallen below
the respective relay set point.
4.4 User Selectable Options
The Model S4000T Intelligent Sensor includes many selectable options to provide the user with
the most flexible H2S gas detector possible. These options include Selectable Sensor Range,
Warn and Alarm Relay Set Points and Configuration, and MODBUS Communications Settings.
These allow the unit to operate with a wide variety of PLC and DCS Systems. The following
sections explain the available options and how they can be customized.
A flow diagram is included to help the user in understanding the process of reviewing and
changing the available options (Figure 11).
NOTE: If the unit was ordered without relays or MODBUS communications, changing the relay
or MODBUS settings will have no effect on the operation of the unit.

4.5 Gas Check Mode
The sensor’s response can be checked without activating external alarms by placing the Model
S4000T in Gas Check Mode. In this mode, the alarm relays are inhibited and the analog output
is fixed at 1.5mA.
4.5.1 Procedure for Checking the Calibration:
Place the magnet over the GM Logo on the cover of the Model S4000T. Remove the magnet
when a flashing pair of bars, “- -” (Figure 12), appear on the display (about ten seconds). Apply
the test gas to the sensor, and the value of the gas concentration will be indicated by the
flashing display and should stabilize in one to two minutes.
Figure 12: Gas Check
When the reading has stabilized and the test is complete, remove the gas and the unit will
return to normal operation, when the concentration drops below 5% full-scale. If, after the
reading has stabilized the sensor is to be calibrated, simply apply the magnet to the GM Logo
on the housing cover, and the unit will enter Calibration Mode.
Gas Check Mode can be aborted if gas has not been applied to the sensor. Simply reapply the
magnet to the GM Logo on the cover and the unit will return to normal operation.
NOTE: The test gas concentration must be at least 10% full-scale before the unit will complete
the Gas Check sequence. If the Model S4000T is placed in the Gas Check mode and
no gas is applied for twelve minutes, the unit will revert to a Fault condition. Reapplying the magnet over the GM Logo will return the unit to normal operation.
4.6 Calibration
General Monitors recommends that the Model S4000T Intelligent Sensor be calibrated one
hour after start-up, and again 24 hours after initial start-up, and that the calibration be checked
at least every ninety (90) days, to ensure system integrity. General Monitors is not implying that
the customer should expect problems with sensor life or stability, but “frequent” calibration
checks merely ensure the integrity of the life protecting equipment.
The above statement is not intended to discourage the customer from checking calibration
more frequently. Frequent calibration checks are recommended for environments that have
29
S4000T
problems, such as mud collecting on the sensor head, sensors accidentally being painted over,
etc.
General Monitors recommends that a calibration schedule be established and followed. A
logbook should also be kept showing calibration dates and dates of sensor replacement.
4.6.1 Calibration Procedure
If Hydrogen Sulfide (H2S) gas is suspected to be present, it will be necessary to purge the
sensor environment with clean air.
Entering Calibration Mode automatically disables the alarm circuits by sending a 1.5mA output
signal and disabling the Warn and Alarm relays, if present. This will also prevent activation of
the remote relay contacts when using a General Monitors Readout/Relay Display Module with
the Model S4000T.
To enter Calibration Mode, place the magnet over the GM Logo on the cover of the unit (Figure
4) and hold it there until “AC” (Figure 13) appears on the display (about ten seconds). The
display will flash the Remaining Sensor Life (Section 4.6.3) for a few seconds. Ensure that the
sensor is seeing clean air during this time.
Figure 13: Automatic Calibration Mode
Apply the calibration gas concentration to the sensor (50% FS of the desired range of H2S).
The display will change from “AC” (Automatic Calibration) to “CP” (Calibration in Progress)
indicating that the sensor is responding to the calibration gas (Figure 14).
Figure 14: Calibration in Progress Mode
After three to five minutes, the display will change from “CP” to “CC” (Figure 15), indicating that
the calibration is complete.
Figure 15: Calibration Complete Mode
Remove the gas and wait for the unit to return to normal operation. The display will indicate a
few percent full-scale and then drop to “0”.
30
S4000T
The unit is now calibrated and the new SPAN value has been stored in the non-volatile memory
(EEPROM).
4.6.2 Aborting Calibration
If calibration is to be aborted, and gas has not been applied, wait ninety seconds and reapply
the magnet. The unit will return to normal operation with the previous calibration values
unchanged.
NOTE: Once gas has been applied, it is not possible to abort a calibration.
If the Model S4000T is placed in the Calibration Mode, and no gas is applied for twelve
minutes, the unit will revert to a Fault (F2) condition. Re-applying the magnet over the GM Logo
will return the unit to operational mode with the previous calibration values unchanged.
4.6.3 Remaining Sensor Life
The Model S4000T Intelligent Sensor provides an estimate of remaining sensor life, in percent
remaining, to provide the user with an early warning of the need for sensor replacement. The
remaining sensor life is updated each time the unit is calibrated. The current remaining sensor
life estimate is displayed during the zeroing portion of a calibration sequence. It can also be
read via the MODBUS interface (Section 8.0).
NOTE: The remaining sensor life provides an estimate of the amount of life remaining for the
sensor. This estimate can be affected by many factors, including environmental
conditions, poisons, etc. It should be used only as an estimate for preventive
maintenance and logistic purposes.
4.6.4 Initializing the Remaining Sensor Life
The remaining sensor life estimate must be initialized each time a new Hydrogen Sulfide
Sensor is installed. The initialization should be done during the first calibration of a newly
installed sensor. After the sensor has been on power for a minimum of one hour, enter
calibration mode as described in Section 4.6. While the display is flashing the remaining sensor
life estimate during zeroing, apply the magnet to the GM Logo on the cover. The flashing
number will change to “100”, indicating the sensor has 100% of remaining sensor life. Complete
the calibration per Section 4.6.1.
4.7 Calibration Equipment
4.7.1 Breaker Bottles and Ampoules
General Monitors offers ampoules with breaker bottles as a method of reliably introducing
calibration gas to the Model S4000T. The ampoule is placed inside the breaker bottle into the
breaker slot, and the breaker bottle is placed over the sensor. The ampoule should contain
50% FS of H2S of the sensor range. Follow the calibration procedure in Section 4.6. When the
display indicates “AC”, break the ampoule by turning the thumbscrew on the side of the breaker
bottle clockwise. The display will change to “CP” indicating that the sensor is seeing the gas.
When the display reads “CC”, the calibration is complete. Remove the breaker bottle and allow
the sensor to see clean air. It will return to normal operation once the gas at the sensor is below
5% of full-scale. See Section 9.5 for available equipment.
31
S4000T
4.7.2 H2S Portable Purge Calibrator
An alternate method for introducing calibration or test gas to the Model S4000T is available.
The H2S Portable Purge Calibrator is a compact, practical, accurate and safe system for field
calibration of H2S Sensors. The bottle is filled with a hydrogen sulfide (H2S) in air mixture and is
available in 7 concentrations. The temperature limitation for operation and storage is 0°F to
+130°F (-18°C to +54°C).
NOTE: Do not store the cylinder with the regulator fully engaged in the cylinder valve.
Use the calibration procedure listed below for H2S Portable Purge calibrations:
Make sure the Portable Purge Calibrator contains a gas concentration equivalent to 50% of fullscale for the unit that is going to be calibrated.
1. Ensure that the sensor is seeing clean air. If it is suspected that hydrogen sulfide gas is
present, it will be necessary to purge the sensor environment with clean air.
2. Place the gas cup over the sensor and initiate the calibration sequence, by placing the
magnet over the GM Logo on the cover of the unit.
3. When the letters “AC” appear in the display window remove the magnet and apply the
calibration gas (50% of full-scale) by opening the valve on the cylinder.
4. When the sensor begins to see the gas, the display will change from “AC” to “CP” to
indicate “Calibration in Progress”.
5. When the calibration sequence is complete, the display will change from “CP” to “CC”
to indicate “Calibration Complete”.
6. Remove the gas by closing the valve on the cylinder, and remove the cup allowing the
sensor to see clean air. The display will change from “CC” to indicate a few parts per
million (ppm) and then drop to “0”.
The unit is now calibrated and the new values have been stored in the EEPROM (non-volatile
memory). See Section 9.5 for available equipment.

6.0 Troubleshooting
CAUTION:
Component level repair must be undertaken either by General Monitors’
personnel, or by competent authorized service engineers. SMT PCB repair shall
only be performed at a General Monitors’ facility. Failure to comply with this
requirement will invalidate the warranty.
Be sure to inhibit or disconnect external alarm wiring before making any check, which might
send the unit into alarm, if an alarm condition will cause a problem.
6.1 Fault Codes & Their Remedies
The Model S4000T has self-diagnostics incorporated into the microprocessor’s program. If a
fault is detected, the output signal will drop to 0mA, the Fault relay will de-energize and a fault
code will be displayed. The output signal will inform a remote display module that the Model
S4000T is in the Fault Mode. The display will indicate a fault code that can be viewed at the
sensor site.
There are nine fault conditions that are monitored by the microprocessor as follows:
6.1.1 F2 - Failed to Complete the Calibration
This fault will occur if the unit is placed in the calibration mode and no gas has been applied
within twelve minutes, or if gas has been left on for more than 12 minutes.
ACTION – Remove gas, if present. Apply magnet to GM Logo on the cover to clear fault. Recalibrate, if necessary.
6.1.2 F3 - EPROM Checksum Error
This fault indicates that the contents of the Model S4000T’s program memory have changed.
This usually occurs when powering the unit up after a lightning strike or large voltage transient
on the power or signal lines to the unit.
ACTION - The unit must be returned to the factory or authorized service center for repair.
6.1.3 F4 - Sensor Heater Open Error
This fault indicates that one of the sensor circuit leads is open-circuited.
ACTION - Check the integrity of all sensor connections, and ensure that the cable from the
Model S4000T to the remote sensor is not damaged. If this does not correct the problem,
replace the sensor and recalibrate.
6.1.4 F5 - Sensor Heater Shorted Error
This fault indicates that one of the sensor circuit leads is short-circuited.
ACTION - Check the integrity of all sensor connections, and ensure that the cable from the
Model S4000T to the remote sensor is not damaged. If this does not correct the problem,
replace the sensor and recalibrate.
34
S4000T
6.1.5 F6 - Low Supply Voltage
This fault occurs if the supply voltage at the S4000T drops below +18.5VDC.
ACTION - Ensure that the supply voltage is at least +20VDC at the Model S4000T.
NOTE: With long supply leads, a considerable voltage drop may occur, due to the electrical
resistance of the leads. The maximum cable resistance, which the Model S4000T can
tolerate, is dependent on the supply voltage. A maximum of 20 ohms per conductor (40
ohms loop), at +24VDC minimum, or a maximum of 10 ohms per conductor (20 ohms
loop), at +20VDC minimum.
6.1.6 F7 - EEPROM Verification Failure
This fault occurs when an attempt to verify the setup/calibration parameters just written to the
EEPROM memory fails.
ACTION - The unit must be returned to the factory or authorized service center for repair.
6.1.7 F8 - Failure to Complete Setup
This fault occurs if the unit is left in setup mode for more than 6 minutes.
ACTION - Exit setup mode. Enter setup mode again if it is necessary, to change any user
selectable options.
6.1.8 F9 - Gas Check Period Exceeded
If the Model S4000T is left in the gas check mode for more than twelve minutes with Test Gas
applied, this fault will occur.
ACTION - Place the magnet over the GM Logo on the cover to return the unit to normal
operation.
NOTE: Anytime a sensor is replaced, the unit should be disconnected from all alarms, as the
unit may go upscale upon power-up.
6.1.9 F10 – Switch Error
This fault occurs if either the remote test, remote calibrate, or magnetic switch are closed for
more than two minutes.
ACTION – Check the wiring on the Remote Reset and Remote Calibrate switches. Once the
short circuit is cleared, the unit will return to normal operation. If the magnetic switch is shorted,
the unit must be returned to the factory or to an authorized service center for service.

8.6 Exception Responses and Exception Codes
8.6.1 Exception Response
In a normal communications query and response, the master device sends a query to the
S4000T and the S4000T receives the query without a communications error and handles the
query normally within the master device’s allowable timeout. The S4000T then returns a normal
response to the master. An abnormal communications produces one of four possible events:
1. If the S4000T does not receive the query due to a communications error, then no
response is returned from the S4000T and the master device will eventually process a
timeout condition for the query.
2. If the S4000T receives the query, but detects a communication error (CRC, etc.), then
no response is returned from the S4000T and the master device will eventually process
a timeout condition for the query.
3. If the S4000T receives the query without a communications error, but cannot process
38
S4000T
the response to the master within the master’s timeout setting, then no response is
returned from the S4000T. The master device will eventually process a timeout
condition for the query. In order to prevent this condition from occurring, the
maximum response time for the S4000T is 200 milliseconds. Therefore, the
master’s timeout setting should be set to 200 milliseconds or greater.
4. If the S4000T receives the query without a communications error, but cannot process it
due to reading or writing to a non-existent S4000T command register, then the S4000T
will return an exception response message informing the master of the error.
The exception response message (ref. No. 4 above) has two fields that differentiate it from a
normal response:

8.6.2 Exception Code
Exception Code Field: In a normal response, the S4000T returns data and status in the data
field, which was requested in the query from the master. In an exception response, the S4000T
returns an exception code in the data field, which describes the S4000T condition that caused
the exception. Below is a list of exception codes that are supported by the S4000T:
Code

05
Acknowledge
06
Device Busy
Description
The function code received in the query is not an
allowable action for the S4000T
The data address received in the query is not an
allowable address for the S4000T.
A value contained in the query data field is not an
allowable value for the S4000T.
An unrecoverable error occurred while the S4000T
was attempting to perform the requested action.
The S4000T has accepted the request and is
processing it, but a long duration of time will be
required to do so. This response is returned to prevent
a timeout error from occurring in the master.
The S4000T is engaged in processing a long-duration
program command. The master should retransmit the
message later when the slave is free.

9.1 Warranty
General Monitors warrants the Model S4000T to be free from defects in workmanship or
material under normal use and service within two years from the date of shipment.
General Monitors will repair or replace without charge any such equipment found to be
defective during the warranty period. Full determination of the nature of, and responsibility for,
defective or damaged equipment will be made by General Monitors’ personnel.
Defective or damaged equipment must be shipped to the General Monitors’ plant or
representative from which the original shipment was made. In all cases this warranty is limited
to the cost of the equipment supplied by General Monitors. The customer will assume all
liability for the misuse of this equipment by its employees or other personnel.
All warranties are contingent upon proper use in the application for which the product was
intended and does not cover products which have been modified or repaired without General
Monitors’ approval, or which have been subjected to neglect, accident, improper installation or
application, or on which the original identification marks have been removed or altered.
Except for the express warranty stated above, General Monitors disclaims all warranties with
regard to the products sold, including all implied warranties of merchantability and fitness and
the express warranties stated herein are in lieu of all obligations or liabilities on the part of
General Monitors for damages including, but not limited to, consequential damages arising out
of, or in connection with, the performance of the product.
9.2 Principle of Operation
General Monitors uses a proprietary Metal Oxide Semiconductor (MOS) film on the sensor for
detecting Hydrogen Sulfide (H2S) gas. The MOS film is deposited onto a substrate between two
electrodes. With no gas present, the measured resistance between these two electrodes is very
high (in the mega-ohms). As H2S adsorbs onto the film, the resistance between the two
electrodes decreases (to kilo-ohms). This decrease in resistance is logarithmically proportional
to the concentration of H2S that is present.
The change in resistance is converted to a change in voltage, and amplified by the input circuit.
This amplified signal is fed to an Analog to Digital (A/D) Converter, converted to a digital signal
and sent to the microprocessor to be processed. The process of H2S adsorbing onto the MOS
film is most effective at an elevated temperature. On the outer edge of the substrate is a heater
ring. The temperature of this heater ring is measured with a thermistor, and kept constant by a
circuit located inside the body of the sensor.
As H2S adsorbs onto the film, electrons move more freely from one electrode to the other. This
is represented as a decrease in resistance. The process of H2S adsorbing onto the MOS film is
completely reversible. As the concentration of H2S decreases (H2S desorbs), the resistance
between the electrodes will increase.
