100 mA). The required power supply is between 12 and 24 V DC and a battery pack can be connected to attain
uninterrupted service even in the event of a power failure. A GSM module can also be installed to allow remote
transmission of measurements *
2.2 COUPLING
The maximum diameter of the sensor that can be used with this converter is 600 mm; backup battery life is affected by the
size of the sensor.
The flow meter can be ordered both in a compact and separate version, with a maximum length of 30mt cable.
2.3 MEASUREMENT CHARACTERISTICS

Liquid conductivity> = 20uS / cm
Sampling: 3.125Hz nominal powered unit (depends on the diameter); battery mode (low power): from 1/5Hz at 1/60Hz
(default 1/15Hz)
2.4 DATA STORAGE
All parameters, totalizers and the register are stored in a non-volatile memory.
2.5 DISPLAY
The LCD can display an 8 and a 6-digit number plus different information icons, allowing the user to view different
information and set many parameters. The details of what can be shown:
•Instant flow
•Positive totalizer (T+)
•Negative totalizer (T-)
•Partial Positive (P+)
•Partial negative (N-)
•Date and time
•Converter temperature
•Code and value of the corresponding parameter

2.6 BATTERY
Lithium batteries are primary energy sources with high energy content, and are designed to satisfy the highest possible
safety standards. However, they can pose a potential hazard if are subject to bad electrical or mechanical use. In many
cases, this is associated with a production of excessive heat, in which the increased internal pressure could cause the cell
to break.
The following precautions should therefore be observed when handling and using lithium batteries fundamental:
•Do not short circuit, charge, overcharge or connect to incorrect polarity
•Do not expose the battery to temperatures higher than those specified or incinerate it
•Do not crush, puncture or open cells or disassemble battery packs
•Do not solder or braze on the battery body or battery packs
•Do not expose the contents to water
Lithium batteries are regulated under the United Nations Model Regulations on Transport of Dangerous goods (United
Nations model rules on the transport of dangerous goods), UN ST/SGAC document. 10-1, 12th edition updated, 2001.
The UN document n. 3091 class 9 covers lithium batteries packed with equipment or within it. The UN document no. 3090
class 9 covers the transport of stand-alone batteries.
The following basic precautions should therefore be followed when transporting lithium batteries:
•Transport only in special packages with special shipping labels and documents
•Use caution when handling, transporting and packing to avoid shorting the batteries.
•The gross mass of the package must be limited according to the type of transport. In general, a gross mass of
less than 5 kg is acceptable for all forms of transport.
•The batteries comply with the requirements stated in "UN Manual of tests and criteria, Part III, subsection 38.3" for
transport by air and in accordance with ADR regulations for transport by truck / ship
REMOVE THE BATTERY FROM THE TRANSMITTER BEFORE SENDING THE
FLOWMETER TO EUROMAG INTERNATIONAL IN THE EVENT OF MAINTENANCE
OR INTERVENTION IN WARRANTY

4. BATTERY LIFE
The converter is supported by an optional lithium battery pack
and can operate for over 10 years in battery mode (depending
on the configuration and working conditions). The residual life
comes estimated by calculating the use of energy for the
duration of the tool, so when the battery is replaced it is
necessary reset the battery usage counter. The ignition the unit
automatically takes the user to a screen selection (see SYSTEM
START). Frequently waking up the unit or entering very long
shutdown times (feature 33) can shorten the expected battery
life.

5. AUTO DIAGNOSTICS
During the measurement process, the MC406M automatically detects if an error condition occurs and possibly stops the
measurement by reporting an alarm indication on the display. The following table describes the various conditions of
alarm and converter behavior.

6.1 FIRMWARE UPDATE
To update the converter with a newer firmware version, select the firmware .hex file and press «Download new firmware
to converter». The progress of the firmware download is displayed while the instrument displays the sequence of internal
operations.
The previously installed firmware is saved in backup on a dedicated memory area, therefore in case of error during
unloading, the converter will automatically restore normal functionality. During the operation the red LED turns on lights up
when the FLASH memory is cleared or written.
At the end of the update process, the unit will restart automatically.
