Safety
CAUTION
RISK OF INJURY AND PROPERTY DAMAGE
lTo minimize the risk of electrostatic charging, provide a suitable
ground connection, and install the equipment in such a way
that no accidental discharges occur.
lWhen Midas S2 reaches the end of its life, it should be disposed
of by local regulations.
lDo not use cleaning solvents or abrasives to clean the gas
detector.
lDo not attempt to modify the product in any way from the
manufacturer’s design or specification. Warranty will be void
and malfunction of the gas detector may result.
lUse only genuine spare parts and accessories with Midas S2.
Malfunction may result if non-standard parts are used.
lMidas® S2 is suitable for ordinary locations only and must not
be installed in hazardous locations.

Mount the Device
Mounting the device on a vertical flat surface.
1. Unscrew the two screws located on the main module.
2. Remove the main module by pulling it forwards off the base
module. At this time, hold the cable gland in the base module
with one hand, and with the other hand, carefully pull the main
module.
3. Unscrew the retaining screws located at the base module, and
then, remove the back plane PCB module.
8

4. Drill two holes 2.3in (58.50mm) vertically apart for 2 x round
head M4 screws, using the separately provided drill template on
the ROHS sheet.
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.
9

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 two screws located on the main module, as identified
in Step 1.

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.
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
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.
11

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.
NOTE: When wiring the Midas S2 Transmitter to a controller, program the
controller for a 1-2 second delay before reporting to prevent false alarms.

14

Attach the pyrolyzer or NDIR
1. Remove the main module as described in the Mount the Device
process.
2. Plug the connector into the socket (as indicated in the image) at
the bottom right of the terminal module through the rectangular
access of the mounting bracket. Align the fitting at the top rear
of the pyrolyzer or NDIR with the gas inlet port at the bottom of
the mounting bracket.
3. Connect the pyrolyzer or NDIR to the detector with the three
provided mounting screws
4. Place the main module and screw the two screws referring to
steps 11 and 12 of ‘Mounting the device.’
15

Install the sensor cartridge
1. Turn the power off.
2. Verify that the part number and type of sensor cartridge are
correct for your application, then remove the sensor cartridge
from the packaging. Remove the BiAS battery module and plug
caps from the sensor cartridge if needed.
3. Push the sensor cartridge gently until fully seated.
4. Confirm the display for gas type and concentration on the
screen.
NOTE: All sensor cartridges are supplied calibrated. Some sensor
cartridges can monitor for more than one type of gas. Please
refer to the User Manual for details about settings and
replacement.

Turn the device on & off
Line Integrity Test
Honeywell offers the optional capability to check for leaks in Midas S2
sample lines. Midas S2 Transmitter for LIT (line Integrity Test) detects any
leak in the tubing with a pneumatic signal change from the valves
installed at the end of the sample line. This test is performed automatically
as a LIT. The Line Integrity Test Option requires the Calibration process.
CAUTION
RISK OF MALFUNCTION
lIf you make any changes to the Pump Module, Check Valve,
Filter, and Tube, and start a new LIT calibration again.
lVerify the Check Valve flow direction during installation.
lVerify both the Check Valve and Tube are firmly assembled.
lMark the insertion from the end of the tube to the length of
15.5mm. When inserting the tube, make sure the insertion is up
to the marked position.
lThe external filter is installed further from the Transmitter, and
the Check Valve is installed closer to the transmitter.
17

Install and leak check
1. Mount the Midas S2 using the integral mounting bracket.
2. Connect the actual inlet & outlet tubes to Midas S2 and turn on
the system.
Verify the Check-Valve is attached to the Sampled Point.
After the Power ON, wait approximately 10 minutes for pump
stabilization and corrective measures.
3. Perform a Block test to ensure internal connections are secure.
Refer to Block test in the Midas S2 User Manual for further
information.
Operation
Select MENU >TEST MODE >LIT and follow the instructions for LIT
enable, Setting, Calibration, and Manual test.
Please secure the calibration procedure for the accurate operation of LIT.
