    Work knob Since 2017 work knob is a standard equipment of every mamos analyser. It ease the performance of service maintenance or random check of analyer’s work. Knob allows to manually select analyser’s work phase and it overrides automatic selection.
  • Page 10: Smps - Switched Mode Power Supply

    2.1.5. SMPS – switched mode power supply Madur provides power supply module that converts mains (either 230 VAC or 115 VAC) to 24VDC required by mamos. SMPS provides not only for the analyser but also for gas dryer and for heated hose steering relay. In case of Split configuration and Twin-split configuration, every remote MD3 dryer is equipped with its own SMPS module.
  • Page 11: Md2 Gas Dryer

    MD2 dryer is not equipped with its own peristaltic pump – removal of the condensate is provided by the peristaltic pump installed inside the mamos analyser. 1. Fan for cooling peltier’s radiator 7. Electric cable from analyser (supply and steering 2.
  • Page 12: Md3 Gas Dryer

    User manual maMoS 2.1.7. MD3 gas dryer MD3 dryer is more efficient conditioning unit in comparison to MD2 (MD3 cooling capability is about 30°C below ambient temperature). It is advised to be used in all industrial applications, like combustion process control, where humidity and pollution level is significant.
  • Page 13: Nafion Gas Dryer

    2.1.9. Dual-mode gas port Gas ports in mamos, both in gas dryer and analyser are dual-mode, i.e. user can establish 1. Standard gas connection using 3x2mm silicon tube 2. Pressure secure connection using 4x2mm PTFE tube and secure it with provided...

  • Page 16: Gas Sensors

    • The most common and standard sensors and their ranges are described on madur’s webpage. Though, it is not feasible to predict and describe all configurations of gas sensors and eliminate their possible divergences, and if the required gas sensor and /or concentration was not listed on our webpage, we encourage to contact our sales team for assistance.
  • Page 17: Ventilation Valve

    Since August 2015, 3-way solenoid valve was replaced with a pair of shut-off valves. In this, new configuration, one of the valves is always energised, while the other one is resting – this provides more stable heat distribution of mamos components.
  • Page 18: Electric Terminals

    (and other mamos connectors) please refer to description shown in the picture below, on the left. Same terminal map is provided in every analyser in a form of sticker inside mamos casing. 3. GND pins for analogue outputs, PWM and digital inputs. GND pins must be shared (more than one...
  • Page 19: Communication Interfaces

    USB connection is initialised (USB cable must be connected to both mamos and PC) 2. RS485 allows to connect up to 15 mamos devices. Connector provides two terminals – to be able to continue ring topology (to connect the next mamos device).
  • Page 20: Stationary Gas Probe

    9. Gas-electric cable. Madur provides 3m gas-electric cable, but for the sake of measurement performance it is advised to adjust this cable length to the absolute minimum (in order to avoid unwanted condensation between probe and gas dryer).
  • Page 21: Heated Line

    2.3.2. Heated line Mamos is ex-situ type of analyser, this means that sample is extracted from the process with the Gas pump. Measured processes, like combustion process, are usually hot and wet. Extracted gas sample cools rapidly, and when its temperature drops below the process’ dew point, a condensation occurs. Unattended condensation must be avoided for a few reasons: solution of measured gases with water –...
  • Page 22: Heated Filter

    External filter also must be heated to prevent condensation (otherwise water with filtered material would create muddy, tacky substance). Filter’s temperature is set to 120°C with 2°C hysteresis. If mamos analyser is delivered with a complete set of accessories for sample collection, i.e.
  • Page 23: Ip55 Cabinet

    2.3.5. Data-logger Mamos can present results as analogue signals (current or voltage signals), also in digital form (RS232 with PC or MODBUS with PLC communication). Additionally, results can be saved in binary form to files stored on SD card via optional equipment: data-logger.
  • Page 24: Control Button

    Mamos uses FAT-16 file system format with cluster size 64kB – this limits the size of SD card to 4GB. Bigger SD cards (including SDHC) are possible to use, but FAT-16 will limit their size also to 4GB. Mamos stores files in root folder only – maximum limit of files in root folder in FAT-16 is 512 = this is the max limit for automated storage. Use can manually create sub-folders and move files there.

  • Page 27: Possible Working Configurations

    3. POSSIBLE WORKING CONFIGURATIONS Yet another example of mamos modularity is how the analyser can be installed. Below we present the most popular configurations. 3.1. Compact configurations The most popular of mamos configurations. All necessary equipment (analyser, dryer, SMPS) are gathered on one mounting plate. This configuration is advised in applications where installation of analyser is possible right next to the sample collection point, and position of analyser is in convenience of maintenance crew.
  • Page 28: Twin-Split Configuration

    Collection points are conventionally named A and B. Measurements are taken in turns, i.e.: measurement place A, ventilation, measurement place B, ventilation, measurement place A, and so on. Mamos informs the user, from where the measurements are taken: on screen, LED status diodes (installed for corresponding device configuration), if necessary on relays and MODBUS registers.

Differential pressure sensor that controls gas port) 5. Nozzle (to dam the gas in order to control flow with pressure flow through the analyser 2.
  • Page 30: Aux Gas Channel

    AUX channel can be disabled under one of two conditions: timer switch – sensors in AUX channel are performing measurements only for the first moments of the measurement phase (this time is adjustable in mamos PC software). •...
  • Page 31: High-Pressure Configuration

    18. Ventilation gas outlet Mamos can work in applications where it is necessary not to disturb the balance of the measured process – this concerns e.g. process under pressure, or when measured gas must not be released to the atmosphere. In such cases, mamos construction is prepared accordingly, i.e. all gas ports are screw-secured (on PTFE tubes), all internal gas links are secured against disconnection.
  • Page 32: Work Modes

    The diagram above, shows another, non-standard feature, i.e. in case where mamos is installed in humid ambient conditions (tropics) it may be necessary to dry not only the process gas but also the gas used for ventilation. In this scenario, gas dryer [9] is installed after solenoid valves [6] 5.
  • Page 33: Firstzeroing

    Ventilation starts each measurement cycle. During Ventilation sensors are provided with neutral gas and perform zeroing. During this phase no usable measurements are performed, but sensors measure and mamos shows their results on the display. Ventilation time is set in the PC program. By default it is set to 15 minutes. It is advised not to set it below 5 min.
  • Page 34: Aux Channel

    Those phases may not occur at all. Purpose of Prestandby phase is to ventilate gas channel and remove any residues of measured gas. This phase last for two minutes and is not adjustable. Standby occurs directly after Prestandby and is when analyser simply rest. Standby time is not defined, mamos stays in this phase until a new work cycle begins. 5.2. Work modes Mamos can work according to several predefined programs.
  • Page 35 User manual maMoS Code Description Default madur setting Additional information Moment of the first zeroing 00:00:00 The first cycle starts each day at midnight. The beginning of the new cycle has a higher priority than any current cycle phase. This means that if the beginning of the new cycle occurs before the current cycle finishes the current phase will be interrupted and the device will start a new cycle.
  • Page 36 User manual maMoS Cyclic mode – behaviour of the analyser after turning on TC – Full cycle time The device set in the cyclic work mode executes the initial phases, i.e. TM – Measurement time Warming and FirstZeroing – and then proceeds directly to the Measurements.

    = 00:00:00 Work mode Measurements triggered with digital input allows the user’s TM – Measurement time = 00:00:00 system to take the full control over mamos work. i.e. mamos receives TV – Ventilation time = 00:15:00 IN1 = Restart measurement cycle information when to start the cycle (by sending signal to digital input IN1).
  • Page 40: Long-Term, Monthly-Cyclic Mode

    User manual maMoS 5.2.5. Long-term, monthly-cyclic mode Monthly-cyclic mode has a length of the cycle equal to the length of the calendar month. This means the analyser’s sensors are zeroed once a month, and then a continuous measurement proceeds (until the next zeroing).
  • Page 41: Restrictions When Using Long-Term Work Modes

    User manual maMoS 5.2.7. Restrictions when using long-term work modes Long-term work modes, especially with long cycle times, result in long interval between zeroings. This lowers the measurements’ accuracy. In order to obtain high measurement accuracy, it is advised to avoid long-term work modes (= perform zeroings of gas sensors as often as it is possible).

    6.3. Replacement of hydrophobic filters in gas analyser Hydrophobic filters protect mamos strategic elements (gas sensors, pump, valve, etc.) against dust and humidity. Gas sample, before entering the analyser should be appropriately conditioned, i.e. dried and cleaned. Though, those hydrophobic filters may in time catch some pollution, and therefore should be periodically checked and, if necessary replaced.

  • Page 46: Troubleshooting In Case Of "Flow Too Low" Error

    As mentioned, mamos analyser is equipped with differential pressure sensor that measures flow through the analyser. By default analyser’s main pump is adjusted to give flow 90 l/h. Flow threshold value is set by default to 30 l/h – this means that if the flow drops below threshold value, mamos will report an error. There are several reasons of such situation.
