1.8 Default Configuration
The Midas S2 gas detector is factory-configured.
NOTE: Oxygen levels are 20.9% v/v in a normal atmosphere, equivalent to 17.3 mA. Use
caution when integrating an oxygen Midas S2 unit using the 4-20 mA output since fault,
inhibit, and no power conditions are below 4 mA and, by default, an oxygen depletion alarm is
triggered on a falling alarm (default 19.5% v/v). In that case, Honeywell recommends one of
the following:
• Use Modbus TCP digital communications
• Use discrete relay inputs instead of a 4-20 mA signal to trigger gas alarms
• Program the control system of the 4-20 mA input with logic and a delay (e.g., 1 second) before
triggering an alarm to determine if the 4-20 mA output is at one of the 0-4 mA conditions
described above.
Contact Honeywell for further information.

CHAPTER
2INSTALLATION
For ease of installation Midas S2 has been designed to allow the installation of the mounting
bracket assembly and main module separately from the other parts of the detector. The
detector location and hard wiring can therefore be completed before fitting the detector’s main
module and sensor cartridge.
CAUTION
RISK OF DEVICE MALFUNCTION
Midas S2 is designed for installation and use in indoor safe areas and non-
explosive atmospheres. Installation must follow the recognized standards of the
appropriate authority in the country concerned. Before installing, ensure local
regulations and site procedures are followed.
Ensure the connection of all modules (e,g pump and cartridge module) with the
main module. Otherwise, Midas S2 can have flow leakage or malfunction.
CAUTION
RISQUE DE DYSFONCTIONNEMENT DE L'APPAREIL
Midas S2 est conçu pour être installé et utilisé dans des zones sécurisées
intérieures et des atmosphères non explosives. L'installation doit suivre les
normes reconnues par l'autorité compétente du pays concerné. Avant
l'installation, assurez-vous que les réglementations locales et les procédures du
site sont respectées.
Assurez-vous de la connexion de tous les modules (par exemple pompe et
module de cartouche) avec le module principal. Sinon, Midas S2 peut présenter
une fuite de débit ou un dysfonctionnement.

2.2 Mount the Device
Mounting the device on a vertical flat surface.
1. Unscrew the two screws located on the main module.
2. Remove the primary module by pulling it forward off the base module. While separating the
base module from the main module, please use the enclosed accessory handle on the back
of the product, as depicted in the picture.
3. Unscrew the retaining screws located at the base module, and then, remove the back plane
PCB module.
4. Drill two holes 2.24in (56.8mm) vertically apart for 2 x round head M4 screws, using the
separately provided drill template on the ROHS sheet.
Midas S2 13 User Manual

5. Partially screw the fixings into the mounting surface.
6. Place the mounting bracket assembly over the screws, so they pass through the mounting
holes and then slide down to locate in the slots.
7. Tighten the screws to secure the mounting bracket assembly.
8. Align the RJ45 socket of the power PCB module in the hole of the mounting bracket to refit
the PCB.

9. Tighten the retaining screw to secure the power PCB module.
10. Wire the device as described in the "Wiring" section.
11. Place the main module back into the base module.
12. Screw the 2 screws located on the main module, as identified in Step 1.
NOTE:Depending on the installation environment of the device, there may be a variation in
pump operation performance due to vibration of a specific frequency or direction, so check
regular pump operation after installation. If you need technical assistance, please contact the
Honeywell Service Team.

2.3 Sample and Exhausting Tubing Calculations
Description of flow rate, maximum pressure, and vacuum at the inlet and exhaust points.
TABLE 2 -1: Inlet sample specifications
Description Maximum
Tubing Length, m (ft) 30 (100)
Back pressure at exhaust point -25.4 cm H2O (-10 in H2O)
Back pressure at exhaust point with LIT Check Valve -12.7 cm H2O (-5 in H2O)
Transport Time (sec), ID 1/8” 125
Transport Time (sec), ID 3/16” 53
Flow rate, cc/min. 500 (Flow is constant) 2
Tubing OD, mm (in) 6.35 (0.25)
Tubing ID, mm (in) 3.18 (0.125)
1Honeywell recommends thick-wall tubing (1/8” ID) for best speed of response. Due to its lower
surface area, thick- wall tubing may require less conditioning than thin-wall tubing.
2The flow rate is electronically maintained at approximately 500 cc/min and may vary within
acceptable tolerances.
Tubing lengths vary among gases. See the Topic 6.6: Gas Table for recommended lengths.
NOTE: Honeywell recommends the use of Teflon FEP (Fluorinated Ethylene Polymer) tubing to
assure proper sample transport. The properties of Teflon FEP make it the best choice for
transporting sample toxic gases to instruments when compared with the properties of other
similar tubing materials.
Midas S2 15 User Manual

TABLE 2 -2: Outlet sample specifications
Description Maximum
Tubing Length, m (ft) 30 (100)
Back pressure at exhaust point 20.3 cm H2O (8 in H2O)
Back pressure at exhaust point with LIT Check Valve 10.16 cm H2O (4 in H2O)
Flow rate, cc/min 500 (Flow is constant)
Tubing OD, mm (in) 6.35 (0.25)
Tubing ID, mm (in) 4.76 (0.188)
2.3.1 Prepare tubing
1. Cut the tube squarely and remove any burrs.
2. Mark from end of tube the length of insertion. The insertion length of Midas S2 from the
end of tube is 15.5 mm.
NOTE: When inserting the tube into the inlet/outlet port of the Midas S2, make sure that it
is inserted up to the marked position.
2.4 In-Line Filters
External filters must be used to protect the tubing from contamination. Use particulate filter
part number 780248 for normal gases and 1830-0055 or 1991-0147 for corrosive gases.
Replace the filter every 3 months. Refer to the Topic 6.6: Gases Table for specific gases.
2.5 Local Detector Option
The Midas S2 gas detector can also be used to monitor for gas at the location of the detector.
To do this, an inline filter is connected to the gas inlet port with the proper filter option of In-
Line Filters. The area around the detector is then being monitored as opposed to a sample
being drawn from a remote location.

2.6 Wiring
Access for the electrical wires to the terminal module is made via the PG16 cable gland located
at the bottom of the mounting bracket assembly. The cable gland can be removed and replaced
with a suitable conduit fitting if required.
The terminals used are suitable for conductors of 24 to 14 AWG (0.5 to 1.8mm Dia.). We
recommend using the 16 AWG (1.5 mm Dia.) conductors.
2.6.1 Terminal layout of the base module
1 Relay NO/NC jumpers 2 4-20mA analog sink/source switch
3 4-20mA analog output terminals 4 Gas outlet port
5 Gas inlet port 6 Cable entry
7 RJ45 connector for ethernet/PoE 8 24Vdc Power terminals
9 Pyrolyzer or NDIR connector 10 Relay Contact terminals
FIGURE 2 -2: Base module components
Midas S2 can be powered by either 24 VDC via traditional discrete wiring or by approximately
48 VDC delivered through the Ethernet cable from a PoE source. In either case, the 4-20 mA
analog output can be used.
NOTES:
lMidas S2 allows only one power source, 24 VDC or PoE. Failure to observe this requirement
may cause damage to the gas detection system and will not be covered by the standard
warranty
lEarthing Requirements: If the Midas S2 unit’s mounting bracket is not connected directly to
a metal surface for earthing purposes, an additional earth wire will be required. Connect a
wire via the PG16 gland to the dedicated earth tag (screw terminal) located on the bottom
bracket and connect the other end of the wire to a dedicated external earthing point. If
Power over Ethernet (PoE) power supply is being used, shielded CAT5 or equivalent Ethernet
cable is recommended. Please ensure that your wiring avoids earth ground loops that may
affect the performance of your equipment.

lInstrument grounding is required to ensure stable performance and to limit the effects of
radio frequency interference before installation.

lPull the terminal blocks to remove them from the connector module.
lConnect the cables to the terminal blocks, referring to the relevant wiring diagram. Strip and
insert the end of each wire into the corresponding terminal hole. Using a flat-blade terminal
screwdriver, tighten the terminal screw until the wire is secured. Use a ferrule on the wire
when necessary. IMPORTANT: Do not over-tighten the terminal screw.
lWhen wiring the Midas S2 Transmitter to a controller, program the controller for a 1-2
second delay before reporting to prevent false alarms.
