It takes a special level of drive and dedication to work in hostile environments, and we believe your workers deserve the same kind of commitment from us when it comes to securing their health and safety.
Power over Ethernet (PoE) connection that enables a single Ethernet connection to be made for all power, control and communication requirements. Overview The Midas-M gas detector comprises of 4 parts: the main module, the mounting bracket assembly, the sensor cartridge and the pump module. Midas-M...
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).
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.

Tubing ID, mm (in) 3.18 (0.125) Honeywell Analytics 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. The flow rate is electronically maintained at approximately 600 cc/min and may vary within acceptable tolerances.
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.
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.

Electrical Connection Midas-M 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. The analog output can be configured for fully isolated operation. With 24 VDC power the 4-20 mA output can be configured for sink, source or isolated output operations.

Mount The Sensor Cartridge The Midas-M Sensor Cartridge enables the detection of a wide range of asphyxiant, toxic, flammable, pyrophoric, corrosive, and oxidizer (including Oxygen) gases. The plug & play Sensor Cartridge is located inside the detector’s chassis. NOTE The Midas-M sensor cartridge is supplied separately.
CHAPTER Device & Web Operations Learn what you can do with your Honeywell Midas®-M Detector, from commissioning to Maintenance Comissioning Comissioning should be followed carefully and only performed by suitably trained personnel. 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.
Monitoring Mode After commissioning, the Midas-M detector is set in the Monitoring Mode, which is the starting point for all of the device's operations. The examples in the following table are for a linear 4-20 mA output over a full scale range of 2 ppm.

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 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.
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.;...
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.

CHAPTER 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.
