Mechanical and electrical installation
M-Log is able to be used for both internal use (placed on a flat surface of fixed onto a wall) and
external use (inside suitable protection boxes).
The use of supports furnished by LSI LASTEM is advisable for indoor applications:
BVA304 Universal tripod to support BVA311 stand
BVA311 Stand for support of n.5 probes and M-Log on tripod or on wall
BVA312 Stand for support of further n.5 probes and M-Log on BVA311 or on wall
BVA314 Sidebar for support of stand on the wall
3.3.1
Instrument power supply
M-Log is equipped with 1,95 A, lithium ion, internal rechargeable battery.
All models can be powered by an external power supply pack (8 ÷ 14 Vdc), by means of connector
placed on top panel of instrument; in this case the positive pole is pole inside the connector. In any
case pay attention not to invert the power supply polarity (although the instrument is protected from
wrong procedure).
For ELO007 and ELO008 models is also possible to power by means of terminal board.
Make reference to table below for connection with instrument-input and sensors-output power-
supply terminals or other devices that need power supply.

When there’s GND wire (grounding), it’s recommended to connect it with 32 terminal.
In case of no switch on of the device, push the RESET button (located on the higher panel of the
instrument) and then try to push the keys combination for switch on; if the sensor is still off, send it
for repair at LSI LASTEM.
WARNING
: in case terminals 5-6 and 16-17 feed outside equipments, they must be equipped with
power fail circuit against short circuits or absorbed currents above 1 A.
WARNING
: in applications where there is LSI LASTEM

must
be powered by means of external power supply pack; the only M-Log internal
battery isn’t able to supply enough power for right operation of connected sensor.
3.3.2
Internal rechargeable battery
The internal rechargeable battery ensures to the instrument the autonomy, the independence and the
handiness during different applications that involve it; it is normally subject to unload. The low
battery signalization occurs on datalogger through three times blinking of LED
