MIDAS-M MULTI GAS TRANSMITTER
Fixed Single Point Extractive
Multi Gas Transmitter
QUICK
REFERENCE
GUIDE

Introduction
The Midas-M® is a Fixed Extractive Single Point with 4-in1 Multi Gas
Detector that draws a sample locally or from a remote point to a sensor
cartridge that is located inside the detector’s chassis. A wide range of toxic,
flammable and oxygen gas sensor cartridges are available that enable
detection of gases used or generated in the Semiconductor and other
manufacturing industries.
NOTE: MidasM is shipped from the factory with the security function
disabled. We strongly recommend enabling this function for safe use of
the detector. To enable it, select Set up > Security and type an 8 character
password.
Safety
CAUTION
Failure to observe the following precautions can cause injury to persons or
damage to property:
• To minimize the risk of electrostatic charging, provide a suitable
ground connection, and install the equipment in such a way that no
accidental discharges occur.
• When MidasM reaches the end of its life, it should be disposed of by
local regulations.
• Do not use cleaning solvents or abrasives to clean the gas detector.
• Do not attempt to modify the product in any way from the manufactur-
er’s design or specification. Warranty will be void and malfunction of
the gas detector may result.
• Use only genuine spare parts and accessories with MidasM. Malfunc-
tion may result if non-standard parts are used.
• MidasM is suitable for ordinary locations only and must not be in-
stalled in hazardous locations.
• Installation 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.

Sécurité
MISE EN GARDE
Le non-respect des précautions suivantes peut causer des blessures cor-
porelles ou des dégâts matériels:
• Pour minimiser les risques de charge électrostatique, veillez à ce que
la mise à la terre soit adéquate et installez l’équipement de manière à
éviter toute décharge accidentelle.
• Lorsque le MidasM arrive en fin de vie, il doit être éliminé conformé-
ment à la réglementation locale.
• N’utilisez pas de solvants de nettoyage ou d’abrasifs pour nettoyer le
détecteur de gaz.
• Ne tentez en aucun cas de modifier le produit à partir de la conception
ou des spécifications du fabricant. La garantie sera annulée et un
dysfonctionnement du détecteur de gaz pourrait en résulter.
• Utilisez uniquement des pièces de rechange et des accessoires d’orig-
ine avec MidasM. Un dysfonctionnement peut survenir si des pièces
non standard sont utilisées.
• MidasM ne convient qu’aux emplacements ordinaires et ne doit pas
être installé dans des endroits dangereux.
• L’installation doit être conforme aux normes reconnues par l’autorité
compétente du pays concerné. Pour l’Europe, voir EN6007914,
EN60079292 et EN6124114. Pour les installations en Amérique du
Nord, le code national de l’électricité (NFPA 70) doit être strictement
observé. Toutes les réglementations locales et nationales appropriées
doivent être observées.

• Partially screw the fixings into the mounting surface.
• Place the mounting bracket assembly over the screws, so they pass
through the mounting holes and then slide down to locate in the slots.
• Tighten the screws to secure the mounting bracket assembly.

• Align the rounded corner at the lower of the main module with the sim-
ilar rounded corner at the bottom of the mounting bracket assembly
• Slide the main module backward while pushing the main module up
after connecting with a mounting bracket so that the PCB and con-
nector and tubes engage simultaneously.
Ensure the PCB, connector, and tubes are fully engaged by firmly push-
ing the main chassis horizontally backward on the mounting bracket
assembly. DO NOT PUSH ON THE LCD AS THIS MAY DAMAGE IT.
• Align the two fixing screws located at the bottom of the chassis with
the screw threads on the mounting bracket assembly.
• Tighten the screws to secure the chassis to the mounting bracket
assembly.

Electrical Installation
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 wire routing of a typical installation is shown in the following
diagram.

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.
If Power over Ethernet (PoE) is used to power the device, then 24 VDC
power must not also be connected to the device, (or conversely if 24 VDC
is used to power the MidasM, then electrical power via the Ethernet port
must not be applied). Failure to observe this requirement may cause dam-
age to the gas detection system and will not be covered by the standard
warranty.
When connecting the wires, ensure that the power switch is in the off
position.

Comissioning
WARNING
Before carrying out any work, ensure local and site procedures are
followed. Ensure that the associated control panel is inhibited to
prevent false alarms.
The following procedure should be followed carefully and only performed by
suitably trained personnel.
1. Ensure the detector is wired correctly.
2. Ensure that the correct sensor cartridge is fitted. (If the
cartridge has not been stored at room temperature, allow one
hour for equilibration.)
3. Ensure the on/off switch on the bottom of the mounting
bracket assembly is in the on position.
4. Apply power to the system.
5. After the startup routine, the detector will display the normal
operating mode.
6. Perform a leak test to ensure all connections are secure.
7. ‘Waiting…’ will be displayed on booting time.
8. Allow the detector to stabilize until the ‘Warm-up’ message
is no longer displayed after booting. The maximum warm-up
time is dependent on sensor type. Refer to individual cartridge
datasheets. Warm-up times are typically much faster.
9. Ensure the correct ID code is selected in Set-up -> alarm
menu
10. If this is a first-time startup, the “Detect New Cartridge ~”
message could be displayed. Press the ‘O’ button to clear the
message.
Mise en service
ATTENTION
Avant de réaliser tout travail, s’assurer que les procédures locales
et de chantier sont suivi. Assurez-vous que le panneau de com-
mande associé est empêché de prévenir les fausses alarmes.
La procédure suivante doit être suivie attentivement et ne doit être effec-
tuée que par personnel convenablement formé.
1. Assurez-vous que le détecteur est câblé correctement.
2. Assurez-vous que la bonne cartouche de capteur est installée.
(Si la la cartouche n’a pas été conservée à la température
ambiante, laissez-la heure d’équilibration.)
