Midas® S2
Fixed single-point extractive gas transmitter

Product Description
The Midas® S2 is a Fixed, Extractive Single-Point Gas Transmitter that
draws a sample locally or from a remote point to a sensor cartridge. A wide
range of toxic, flammable and oxygen gas sensor cartridges are available
that enable the detection of gases used or generated in semiconductor
manufacturing operations, light manufacturing environments, and
national and university labs that specialize in semiconductor processing
research.

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.
lInstallation must be by the recognized standards of the
appropriate authority in the country concerned. For Europe, see
EN60079-14, EN60079-29-2, and EN61241-14. For
installations in North America, the National Electrical Code
(NFPA 70) should be strictly observed. All the appropriate local
and national regulations should be observed.
lIndoor use only.

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.

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.
