Product Description
The Honeywell 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. 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. Midas-M is wall mounted and displays gas concentration, alarm, fault and status information via its backlit LCD and LEDs. A simple to use 4-button keypad located under the display provides the facility to set-up, review, operate and make changes to the detector's configuration.

Default Configuration
The Midas-M 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-M 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 Analytics 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.

Installation
For ease of installation Midas-M 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.
WARNING Midas-M is designed for installation and use in indoor safe area non-explosive atmospheres. Installation must be in accordance with the recognized standards of the appropriate authority in the country concerned. Prior to carrying out any installation 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-M can have flow leakage or malfunction.
Mount the Transmitter Device
The Midas-M gas detector has an integral mounting bracket assembly that is easily mounted to a suitable vertical surface such as a wall, tool housing, mounting plate on a pole etc.

Due to its lower surface area, thick- wall tubing may require less conditioning than thin-wall tubing. 2 The flow rate is electronically maintained at approximately 600 cc/min and may vary within acceptable tolerances. Tubing lengths vary among gases. See the Gas Chart for recommended lengths.
NOTE Honeywell Analytics 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.

Prepare Tubing
1. Cut the tube squarely and remove any burrs. 2. Mark from end of tube the length of insertion. The insertion lenght of Midas-Mfrom the end
of tube is 15.5 mm.
NOTE When inserting the tube into the inlet/outlet port of the Midas-M, make sure that it is inserted up to the marked position.
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 Gases Table for specific gases.
Local Detector Option
The Midas-M gas detector can also be used to monitor for gas at the location of the detector. To do this, an inline filter is simply connected to the sensor cartridge gas inlet port. The external dust filter part number is 780248 for normal gases and 1830-0055 or 1991-0147 for corrosive gases. The area around the detector is then being monitored as opposed to a sample being drawn from a remote location.

User Manual
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. Typical wire routing
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 damage 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.
NOTE Earthing Requirements: If the Midas-M unit's metal chassis is not connected directly to a metal surface for earthing purposes, an additional earth wire will be required. Connect a
Midas-M
19
User Manual
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 Ethernet cable is recommended. Please ensure that your wiring avoids earth ground loops that may affect the performance of your equipment.
NOTE Instrument grounding is required to ensure stable performance and to limit the effects of radiofrequency interference before installation. The following diagram shows the terminal module layout and terminal identification as well as the jumper locations.

Calibration & Bump Test
All Midas-M sensor cartridges are pre-calibrated by Honeywell Analytics using traceable gas standards and approved calibration methods to a proven ISO 9000 quality controlled procedure. The Midas-M sensor cartridge design is very robust and resistant to long term drift; in fact in a normal operating environment it is possible to extend the calibration interval with Midas-M up to 24 months (subject to local requirements concerning calibrations). This design feature is another element that supports Midas-M as a long term cost effective gas detection solution. Honeywell Analytics recommends frequent bump testing to confirm performance.
NOTE It is the sole responsibility of each user to determine their own calibration and bump test schedule based on their own safety assessments and understanding of local requirements.
Just prior to commissioning, each Midas-M unit should be zero calibrated to ensure accuracy. It is recommended that the unit be powered with the cartridge installed for at least 30 minutes prior to conducting a zero calibration. A second zero calibration may be required after a 24 hour period which is dependent on the site conditions. O2 sensors are not zero calibrated but should be span gas calibrated. See the Gas Table for span gas calibration details. If the ambient condition in the area the detector is monitoring experiences a long-term change, it is necessary to perform a zero calibration to allow the unit to adjust to the new conditions.
NOTE When performing a zero calibration, be sure that the area is free of the target gas and/or interfering gases (refer to the cartridge data sheets for further details), as the presence of a background gas will affect the ability for the detector to properly calibrate to the correct levels. If the sample area cannot be verified to be free of the target gas or cross-sensitive gases, use a cylinder of zero air to perform the calibration
Calibration of an electrochemical sensor cartridge is a relatively complex discipline to master and it is possible that in less ideal field conditions the calibration can be far less accurate than under laboratory conditions and therefore substantial inaccuracies can be introduced. In the absence of any formal calibration policy by the end user, it is preferable to retain the original factory calibration. Care must be taken to ensure that the correct materials for an extractive application are obtained from reputable suppliers and are of proven quality and composition. Inappropriate calibration equipment will lead to under - or over-presenting the wrong concentration of gas to the sensor cartridge during the calibration period. Likewise contaminated or inadequately flushed tubing and other gas-wet surfaces can also introduce errors into the calibration process. Only qualified, trained personnel should attempt to perform gas calibrations; contact your local Honeywell Analytics Service Representative for further details on calibration services. Testing should be performed at the end of the sample tube or at the detector with a short length of tubing. Applying gas with a short length (less than 5 feet/1.5 meters) of clean FEP tubing will give optimal results for confirming the accuracy and response time of the cartridge. Applying gas at the end of the installed sample line will test the full system including the whole length of tubing. This will verify the integrity of the tubing. Sample line integrity can also be
Midas-M
39
User Manual
checked by performing a leak check. Note that there will be additional transport time due to the tubing length and conditioning the gas-wet surfaces. Bump tests are also used as an approximate means to present a controlled gas release to the sensor cartridge in order to verify that the transmitter does respond accordingly. Bump testing is popular as typical experiences show that a smaller list of easier to handle gases can be used to provide functional tests on a wider range of gas types. In the absence of a formal calibration policy from the end user, Honeywell Analytics would recommend a minimum semi-annual schedule of at least one bump test per sensor with the appropriate test gas. Bump testing may reduce sensor cartridge lifetime and the accuracy of the calibration if applied incorrectly or too frequently. Use only the target gas or the recommended bump test gas. Zero calibration is a recommended procedure that should be performed periodically to improve the performance of the sensor. This is particularly important when the sensor is operating outside of normal environmental conditions (20�C, 50% rH). The Gas Table indicates the recommended calibration or bump test gas for the Midas-M sensor cartridges: Consult with your Honeywell Analytics Service Representative for approved methods and materials before commencing calibrations and bump tests.
Bump Test
A bump test is not intended to be an accurate calibration, but is used as a confidence check to ensure that the gas detection system is functional. Since some of the target gases are difficult to handle, bump testing often makes use of cross sensitivities so that more convenient gases can be used. In bump test mode, the Modbus/TCP outputs are not inhibited. Only the 4-20 mA and alarm outputs are inhibited. The bump gas test is a functional check only. Consult local guidelines for recommended best practices. Bump test concentrations are calculated to generate a minimum first alarm level response.
Preparation
Most of the test gases are highly toxic. It is essential that personnel using these toxic gases be trained in their use. Ensure that the test gas will be vented safely. Applying test gas may cause alarm, fault or maintenance fault indications on the 4-20 mA loop, relays or digital outputs. Before starting a test, ensure that suitable steps have been taken to prevent these indications from triggering unwanted actions. The Midas-M gas detector has a special mode for bump testing where the alarm outputs are inhibited.
Finishing
Wait for the gas reading to return to normal levels. This may take some time, especially if concentrations above the recommended levels have been used or if the test gas has been applied for an extended period of time. Ensure that any latched faults or alarms that have been generated by the testing have been cleared.

User Manual
Make sure that the gas detection system is fully restored to its normal operating state and that any control system overrides used during the testing have been removed. The alarms generated by the testing will have created entries in the transmitter's history log.
Troubleshooting
If the test does not produce a satisfactory result, check the following points: l Check the gas cylinder concentration and type are correct l Check the expiration date of the cylinder. l Check that there is sufficient gas left in the cylinder. l Check that there are no leaks on the test system. l Make sure that the tubing length is as short as possible and that there are no blockages. l Make sure that the transmitter is not displaying a fault before the test is started.
Internal Web Server
The Midas-M gas detector unit utilizes an Ethernet port with the TCP/IP protocol as standard. The Midas-M can function as a HTML web page server and these web pages can be viewed on external computer equipment (PC, PocketPC etc.) by using a standard software program, i.e.; Microsoft Internet Explorer 11, Safari, or Chrome . These web pages replicate the user interface on the front panel of the Midas-M in a more flexible and friendly format for diagnostic and data entry purposes. The web pages also contain additional features not available via the keypad. This procedure explains how to view web pages for a single Midas-M which is connected to a single PC only. Of course it is possible to connect hundreds of Midas-M units to an Ethernet network. More information may be required from the local IT department and Honeywell Analytics as appropriate.
Physical Network Components
The Ethernet physical network is intended to connect computers to other computers through hubs. MIDAS-M has a 10/100 Mbps Ethernet transceiver and supports Auto-MDIX. It supports Auto-Negotiation for selecting the highest performance mode of operation. To use CAT5 standard or higher shield ethernet cable is recommended for the highest efficiency communication speed.
Internet Settings
Communications requires knowledge of the IP address and netmask of both the Midas-M and the PC. Unless the Midas-M is connected to a network with a DHCP server, the addresses must be set manually. The procedure for setting the IP address of a PC is detailed in the following example using a PC loaded with Microsoft TM Windows 7 and Internet Explorer version 11.0 or higher as illustrated as follows. In the usual case the netmask for both computers should be set to 255.255.255.0. The mostsignificant three bytes of the IP address must be identical and the least-significant byte must be
Midas-M

User Manual
unique. For example, if the IP address of the Midas-M was set to 169.254.60.47 (the factory default) then an appropriate IP address for the PC would be 169.254.60.42. IP Address setting in Windows 7
Running the Web Server
In a web browser, set the URL to "http://xxx.xxx.xxx.xxx" where the "xxx" fields are replaced with the IP address of the Midas-M.

Maintenance
Midas-M is a fully serviceable product designed with modular components that can be readily replaced by trained service personnel so as to minimize the time that the gas detector is not available. External in-line air filters should be replaced every three months or more frequently if the system is sampling in environments that have high levels of particulate matter or very acidic / wet atmospheres. Similarly, the internal particulate filter should be replaced every two years or more frequently if the sample lines are prone to heavy contamination. Refer to the following table. Every sensor cartridge is shipped with a 2 years warranty. All sensor cartridges are factory calibrated to traceable national standards before shipment to the end user. Note that testing or calibrating with the wrong (incorrect, out of date, non-traceable) calibration gases, calibration equipment, methods or operating conditions can actually damage the sensor cartridge's lifetime and alter the calibration adversely. Only qualified calibration technicians should attempt to calibrate the Midas-M gas detector. The internal pump module is designed to operate for a minimum of 24 months and it is recommended that this pump module (part number MM-PM ) be replaced every 2 years.

Every sensor cartridge warranty: Typically, two years depending on the sensor type. The Bias battery will last only about six months. After replacement, allow at least a day for the cartridge to reach equilibrium.
System Leak Check
When performing a leak check, the Midas-M must be placed in Inhibit mode to prevent false concentrations or faults to be activated when plugging the Sample or Exhaust Lines. Example: O2 (oxygen) � plugging of the ports causes the O2 levels within the Midas-M flow path to be depleted as the sample becomes stagnant. The result is the concentration levels begin to fall and trigger the alarms for the O2 depletion. 1. Place the Midas-M into Inhibit. 2. Plug the Inlet Sample line.
3. The flow meter indicators will begin to drop and ultimately disappear within seconds. 4. Continue to keep the port plugged until the Midas-M reports an "F41" (Flow Fail) � approximate time to fault is 24 seconds. 5. Remove the plug. 6. Allow 15 seconds or so to allow the Midas-M flow to stabilize then clear the fault by pressing and holding `X' 7. Plug the Outlet Exhaust line. 8. The flow meter indicators will begin to drop and ultimately disappear within seconds. 9. Continue to keep the port plugged until the Midas-M reports an "F41" (Flow Fail) � approximate time to fault is 24 seconds. 10. Remove the plug.

1 Recommended to keep the sample lines as short as possible where the RH condition at the sample point is high (above %50 RH); there will be some sample loss due to absorption onto the sample line. 2 An ozone generator can be used instead of 1 ppm NO2.
Bump Testing Notes: As an alternative, the actual target gas can always be used instead of a cross-sensitive gas. Higher concentrations than the recommended ones can be used if necessary, but extra time may be needed for the reading to recover to zero. IMPORTANT: this should only be done once to avoid the danger of poisoning the sensor.

User Manual
Reflex
Midas-M uses patented Honeywell Analytics technology to continuously monitor the health check status of specific electrochemical cells and alert the user if a cell enters a variety of fault conditions (such as open or short circuit etc.) which would leave the cell unable to detect gas and raise an appropriate alarm signal. REFLEX� overcomes this unseen failure mode by applying periodically a special electronic pulse to the cell and reviewing the `echo' from the cell as it responds to the applied signal. If the cell is deteriorating within certain pre-set limits based on the received signals then Midas-M will decrease the REFLEX sampling interval in order to establish the actual viability of the cell. Within a relatively short time, Midas-M will be able to alert the user via fault codes that the electrochemical cell is likely to be requiring replacement and is possibly unable to correctly detect gas. REFLEX is not required for pellistors, IR, oxygen electrochemical cell or bias electrochemical cell as these sensor cartridges provide alternative electronic means to indicate open circuits and other sensor cartridge damage issues.

User Manual
A Modbus/TCP Interface
The Midas-M gas detector can report concentration information in a variety of formats including relay contact closure, an analog 4-20 mA loop, Ethernet/ IP/HTML web pages and via the Modbus/TCP networking protocol. This section defines the format of data in Modbus/TCP registers. More information about Modbus/TCP can be obtained from www. modbus.org. The Midas-M is a Modbus/TCP "server" as defined in the MODBUS Application Protocol Specification V1.0 . It supports command 03 ("read holding registers") for registers 40001 to 40122 as listed in the following table. The Midas-M reports floating-point concentration numbers in little-endian or Intel format. This is scaled in units of ppm for gasses which have display units of ppm or ppb. For other display units the concentration is scaled directly in display units. This applies to registers Gas Concentration and Alarm Threshold. The Midas-M fills 122 Modbus/TCP holding registers as listed in Table 1. The Monitoring Status register is a concise summary of Midas-M status. The other registers provide more complete information.

Security
Midas-M is shipped from the factory with security disabled. It is recommended to enable the security function for safe use of the device. The security function can only be enabled through the Set up > Security menu of the local UI and requires at least 8 of passwords. If the security function is enabled, the web server can be accessed through HTTPS. And it is recommended to clear the browser cache to access the web server through HTTP after security is disabled.
Modbus TCP
The MODBUS protocol does not have any authentication and integrity checking function. So the bump-in-the wire solution is recommended using a network equipment with SSL VPN Firewall function to protect the Midas-M from external attacks.
DOS attack
The web application may not work due to DoS attacks. The Midas device is even needed to restart for the web application to work properly. So the bump-in-the wire solution is recommended using a network firewall hardware solution that can detect and block DoS attacks.
