4. Introduction
The Series 3000 MkIII gas detector is designed to detect toxic or oxygen gas hazards in zone 0 or
1 or 2 or 20 or 21 or 22 hazardous areas in Europe, and hazardous locations Class I, Divisions 1 &
2, Groups A, B, C & D; Class II, Divisions 1 & 2, Groups E, F & G application in North America. A
local LCD provides gas type and concentration information and when magnetically activated enables
non-intrusive one man calibration and operation. The sensor interface to the transmitter is Intrinsically
Safe (IS) allowing it to be ‘hot swapped’ without the need for removing power to the detector. The
replacement plug in smart sensors are supplied pre-calibrated. A remote sensor mounting kit allows
the sensor to be mounted up to 50 feet (15 meters) from the intrinsically safe transmitter. The output
from the transmitter is an industry standard 2 wire 4-20mA loop (sink) suitable for connection to a wide

5.1 Mounting and location of detectors
Caution: The location of the detectors should be made in accordance with any relevant
local and national legislation, standards or codes of practice. Always replace detectors
with a detector of the same type.
The detector should be mounted where the gas is most likely to be present. The following points should
be noted when locating gas detectors.
• When locating detectors consider the possible damage caused by natural events e.g. rain or ooding.
• Consider ease of access for functional testing and servicing.
• Consider how escaping gas may behave due to natural or forced air currents.
Note: The placement of detectors should be determined following the advice of experts having specialist
knowledge of gas dispersion, experts having knowledge of the process plant system and equipment
involved, safety and engineering personnel. The agreement reached on the location of detectors should
be recorded.

6.1 Detector wiring schematic
Caution: All electrical connections should be made in accordance with any relevant local
or national legislation, standards or codes of practice.
6.2 Maximum cable length calculation
The limiting factors in calculating maximum cable lengths when using barriers and isolators are the
total capacitance and inductance. Barriers and isolators have a xed amount of capacitance and
inductance that can be connected to their outputs. The cable between the eld device and barrier/
isolator will have a value for capacitance and inductance per metre or kilometre that will be available
from the manufacturer or supplier.
To calculate the maximum cable lengths, calculate the total capacitance and inductance for the
length of cable, add any capacitance or inductance due to the eld device (Series 3000 MkIII
capacitance and inductance = 0). The resulting totals should not be greater than the value shown for
the barrier or isolator.
Example using MTL7787+ dual channel zener barrier:
Capacitance permitted by the barrier = Co
Inductance permitted by the barrier = Lo
Internal capacitance of the eld device = Ci
Detector Supply Vd
• 10 Vdc(+/-10%) < Vd < 30 Vdc (max)

Diagram 8: Dual barrier schematic

13
SERIES 3000 MKIII TECHNICAL MANUAL MAN0917_Issue 6_08/2015
Internal inductance of the eld device = Li
Capacitance of the cable per metre = Cc
Inductance of the cable per metre = Lc
Total allowable capacitance for the cable = Ccmax
Total allowable inductance for the cable = Lcmax
All capacitance measurements are in microfarads, all inductance measurements are in millihenries.
Using the Safety Description of an MTL7787+ for a IIC gas as an example:
Safety Description: 28v, 93mA 0.651W
Co = 0.083 microfarads
Lo = 3.05 millihenries
Total allowable capacitance for the cable Ccmax = Co-Ci, Ccmax = 0.083-0 = 0.083
Total allowable inductance for the cable Lcmax = Lo-Li, Lcmax = 3.05-0 = 3.05
If the cable type is known, then the parameters from the manufacturer should be used otherwise refer
to the values suggested below:-
In North American Installations:
Cc = 60pF/foot (0.00006 microfarads) and Lc = 0.2 microhenries/foot (0.0002 millihenries)
In European Installations:
Cc = 200pF/m (0.0002 microfarads) and Lc = 0.66 microhenries/m (0.00066 millihenries)
Using the values per metre for European Installations:
Maximum length of cable due to capacitance = Ccmax/Cc = 0.083/0.0002 = 415 metres
Maximum length of cable due to inductance = Lcmax/Lc = 3.05/0.00066 = 4621.21 metres
As is often the case, capacitance is the most limiting gure and so the maximum cable length will
be 415 metres.
Note: Due to circuit limitations, do not run cable in excess of 1219metres (4,000ft) even if the above
formulas allow a longer length.
6.3 Suggested barriers and isolators
Listed below are some suggested barriers and isolators for use with Series 3000 MkIII.
MTL7728+ (single channel zener barrier)
MTL7787+ (2-channel zener barrier)
MTL5042 (Galvanic Isolator)
Pepperl+Fuchs KFD2-STC4-EX1 (Galvanic Isolator)
Note: It is up to the user to ensure that the barrier or isolator used is suitable for their application ,
and carries a listing (certication) appropriate to the authority having jurisdiction.
Note: In case the user installs the detector in safe area without any barriers and any isolators, an
appropriate load resistor (33~250Ω) must be connected to the detector.
Caution: A single channel barrier solution is only suitable when used with a controller that
provides the load resistor in the source or positive supply line where the negative of the
barrier input is tied to earth ground.

SERIES 3000 MKIII TECHNICAL MANUAL MAN0917_Issue 6_08/2015
6.5 Cable and earth / ground connection
Between the Controller and Transmitter use 2 core (plus screen 90% coverage), suitably mechanically
protected copper cable with a suitable M20 gland, or ¾ in. NPT steel conduit, with 0.5 to 2.0mm2
(equivalent approx. 20 to 14AWG) conductors. Ensure the cable gland is installed correctly and fully
tightened.
To ensure good EMC/RFI immunity bond the system to ground / earth as shown in the diagram below.
Notes:
• No two ‘Earth Points’ should be connected via screen and / or conduit so as to avoid ‘ground loops’.
(Except between the sensor and transmitter which is a digital link).
• Where multiple ‘Earth Points’ are unavoidable (e.g. transmitter mounted on metal superstructure
which is earthed then screen and / or conduit to controller should be isolated appropriately).
• ‘ Bonded Points’ (continuity of screen) may be achieved using appropriate glands / cable or conduit;
internal and external ‘Earth Points’ in the transmitter are provided.

1. Check that the transmitter is wired correctly according to this manual and the associated control
equipment manual.
2. Unscrew the weatherproof cover, loosen the sensor retainer locking screw and unscrew the retainer.
3. Plug in the sensor taking care to align the sensor pins with the connector holes in the pcb.
Caution: For toxic sensors, remove the shorting clip from the bottom of the sensor prior
to installation. For O2 sensor, there is no shorting clip provided.
Caution: Ethylene Oxide sensors are supplied on a transportation board in order to keep
the cell biased at the correct level. Once removed from the transportation board the
sensorshouldbettedtothedetectorassoonaspossible.
Ifthesensorisnotttedtothetransportationboardorapowereddetector,itsbiaswill
decay and the sensor will take up to 24 hours to recover. During this period the sensor
will not function as a gas detector, reporting a gas reading above full scale.
4. Ret the sensor retainer, tighten the locking screw and ret the weatherproof cover.
5. Apply power to the associated controller which will in turn provide power to the detector.
6. The detector output will be forced to 3mA (default fault / inhibit).
7. The detector display will enter a start up routine rst displaying all the LCD segments and symbols, then
the transmitter loads the data from the sensor and checks if it is the same type transmitter and sensor
software version numbers, gas type, the detection range and span calibration gas level, estimated
time to next calibration due, self test result, and nally warm up period shown as a countdown to 0.
(Countdown time varies from 30 seconds to 3 minutes, depending on the sensor type).
8. Once countdown is complete, the detector will enter normal ‘monitoring’ mode.
Note: Calibration is mandatory before the detector can be used for gas monitoring. Refer to Section
8.2 Calibration for the proper procedure.

SERIES 3000 MKIII TECHNICAL MANUAL MAN0917_Issue 6_08/2015
8. Magnetic switch activation
Series 3000 MkIII uses magnetic switches to enable non-intrusive operation. To activate a magnetic switch,
hold the magnet up to the glass window directly over the magnetic switch area. The switch is activated
when you then remove the magnet. For example: to put the detector into Menu Mode hold the magnet
over the ‘’ magnetic switch for 5 seconds, and then remove the magnet. The detector enters menu
mode on removal of the magnet (not automatically after 5 seconds). Similarly, when changing values or
navigating in a menu using the ‘’ magnetic switches, hold the magnet up to the glass window directly
over the switch momentarily, and then remove to activate the switch. In some menus where the displayed
value can be changed the magnet can be held over the switch and the numeral on the display will scroll
through the available values. Remove the magnet when the required value is displayed.

Notes:
1. Default ranges have been selected based upon recommended exposure limits set around the world.
2. Where ranges signicantly above the recommended defaults are needed select a gas cal point
near to the required alarm point or between 30 and 70% of full scale. Consideration must be given
to providing adequate ventilation of the calibration gas and ensure there is no exposure of the user
to toxic levels of gas.
For details of how to change the conguration for full scale range, calibration gas level, calibration
interval, inhibit current & timeout and access password refer to section 12.

8.2. Calibration
WARNINGS
• It is recommended to bump test the sensors frequently to ensure proper operation.
8.2.1 Zeroing and span calibration
Caution: Before initial calibration allow the detector to stabilize for 30 minutes after
applying power. When in zeroing and span calibration mode the current output from the
detector is inhibited (default 3mA) to avoid false alarms.
It is recommended for most sticky gases the tubing should be PTFE with short pieces of
rubbertubetomakethenalconnectionduetotheinexibilityofPTFE.Thisminimizes
adhesion of the gas to the tube surface and allows for more accurate measurement.
ForHydrogenSuldeorEthyleneOxide-typesensorsrefertotosections8.2.2or8.2.3
respectively before conducting calibrations.
Note: It is recommended that the calibration is made where the sensor / transmitter have stabilized with
their local environment. It is recommended that calibrations be performed at a stable temperature in
which the system is to be used. Re-calibration is recommended if the temperature of local environment
has varied by more than +/-15 degrees C from the temperature of calibration.
It is essential that the sensor is tested frequently to be sure the system is operating properly. Typically
gas detectors should be tested at least twice per year. However it is recommended that testing is
conducted on a more frequent basis after initial start up as sensor operation and performance will vary
in different environmental conditions and in the presence of other gases. It is the responsibility of the
user to determine an appropriate calibration frequency for the application.
To calibrate the detector, use an appropriate span gas cylinder, ow regulator set to 300-375mL/min,
tubing, magnet and calibration gas ow housing. A compressed air cylinder (20.9%Vol oxygen) should
be used to perform the zero calibration if the area where the detector is located contains any residual
amount of the target gas. If no residual gas is present then the background air can be used to perform the
zero calibration. Contact your Honeywell Analytics representative for details of suitable calibration kits.
To calibrate the detector follow the procedure below.
Note: the Oxygen sensor does not require a zeroing procedure. Background air (20.9%Vol oxygen)
can be used to span the oxygen sensor in place of a compressed air cylinder (20.9%Vol oxygen). For
oxygen sensors only do parts 1-4, 13, 14 (if compressed air cylinder is used), 15-19 and 24 of the
procedure below.
1. If using compressed air, push the calibration gas ow housing onto the bottom of the sensor and
apply the gas.
2. To access the calibration mode, hold the end of the magnet over the switch located at the top centre
of the detector display for at least 5 seconds and then remove.
3. The display will indicate the rst menu mode menu ‘SEt CAL’.

4. Put the magnet over the ‘’ switch and remove to enter the Calibration menu.
5. The display will show the current gas reading, ‘ZEro’ and the ‘ ’ icon ashes.
6. When the zero gas reading is stable use ‘ to conrm zero calibration.
7. If successful the display shows ‘ZEro PASS’ (if not successful, the display shows ‘ZEro FAIL’ and
returns to menu mode).
8. If using zero-air, turn it off. Zeroing is complete and saved.
9. The display shows ‘SPAn’ with ‘YES’ ashing.
10. If span calibration is required use ‘’ proceed to the next step. If span calibration is not required,
use ‘▲▼’ to select ‘No’ and ‘’ to return to menu mode.
11. The display shows the current calibration span gas concentration ashing. Use ‘▲▼’ to change the
calibration span gas concentration, and ‘’ when required span calibration level is set.
12. Span calibration point is displayed with ‘YES’ ashing. Use ‘’ to conrm or ‘▲▼’ to select ‘No’ and
return and enter a new span calibration point.
13. The display will show the current gas reading, ‘SPAN’ and the ‘
’ icon ashes.
14. Connect the regulator to the span gas cylinder.
15. Apply the span gas to the sensor using the calibration gas ow housing. The live gas reading is
displayed. When the reading is stable, use ‘’ to conrm span calibration.
16. If the sensor cell has been replaced the following display may be shown.
