4. Introduction
The Series 3000 MkII gas detector is designed to detect toxic or oxygen gas hazards in Zone 1 or 2 or 21 or 22
hazardous areas in Europe and North American Class I Division 1 or 2 areas and Class II Division 1 or 2 areas. 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 explosion proof transmitter housing. The output from the transmitter is an industry standard 2 wire 4-20mA
loop (sink) suitable for connection to a wide range Honeywell Analytics or 3rd party control equipment / PLCs.
4.1 Product overview
The Series 3000 MkII detector comprises of the main parts shown below.
4.2 Transmitter
The transmitter cover has a glass window which allows use of the magnet to activate the three user
interface magnetic switches that are located on the front of the display module. This allows for non-

6.3 Terminal connections
All electrical connections are made at the terminal module. To access the terminal module follow the
procedure below:
1. Remove the detector’s cover by unscrewing it in a counter-clockwise direction.
2. Remove the display module by pulling it rmly away from the enclosure without twisting it.
6.4 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 explosion-proof 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.

7. First time switch on
After mounting and wiring the transmitter, the plug in sensor should be tted and the installation visually
and electrically tested as below.
WARNING
Prior to carrying out any work ensure local and site procedures are
followed. Ensure that the associated control panel is inhibited so as
to prevent false alarms.
Minimum and maximum controller alarm levels should not be set at less
than 10% or greater than 90% of the full scale range of the detector.
Caution: The following procedure should be followed carefully and only performed
by suitably trained personnel.
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.
4. Ret the sensor retainer, tighten the locking screw and ret 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.

16
SERIES 3000 MKII TECHNICAL MANUAL S3KMKIIMAN_MAN0878_Issue 6_01/2014
8. Magnetic switch activation
Series 3000 MkII 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.
For the purposes of this manual, the instruction to use ‘’, ‘’ or ‘’, means to activate the relevant
magnetic switch as described above.

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 rubber tube to make the nal connection due to the
inexibility of PTFE. This minimizes adhesion of the gas to the tube surface
and allows for more accurate measurement.
For Hydrogen Sulde type sensors refer to section 8.2.2 before conducting
zero and span calibration.
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 conrm 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 conrm 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 conrm span calibration.
16. If the sensor cell has been replaced the following display may be shown.

17. Use ‘▲▼’ to select ‘YES’ if the sensor cell has been replaced or ‘No’ if it has not been replaced.
WARNING
Answer Yes to “CELL/rEPL” ONLY in cases where the “Serviceable Sensor Cell
Replacement” procedure (sec. 15.2) was been performed. Answering Yes in cases
where the cell has not been replaced could result in the inability of the Series 3000
to recognize an old cell with an inadequate output.
It is recommended to bump test the sensors frequently to ensure proper operation.
18. If the sensor cell has been replaced use ‘’ to conrm the gas reading.
19. If the span calibration is successful the instrument will briey display ‘SPAn PASS’ (if fails ‘SPAN
FAIL’ displayed and returns to menu mode).
Note: the calibration due warning counter is reset after a successful calibration. See section 12 for
further details of setting a calibration due warning.
20. The display alternates between “Pur GAS” and the gas reading to indicate that the unit is expecting
the span gas to be removed from the sensor.
21. Promptly switch off the calibration span gas and remove the calibration gas ow housing from the
sensor to allow the gas to disperse.
22. When the reading falls below 50% of the calibration gas level the display indicates a countdown
(up to 180 seconds dependant on gas type).
23. When the countdown is nished, the calibration procedure is complete.
24. The instrument returns to the ‘SEt CAL’ menu. Activate the ‘▲’ or ‘▼’ switch to select another menu
or select ‘QuIT’ to return to normal monitoring mode.
