Page 6: Introduction
(6) - Terminal board Fig. 1 – Instrument description. On the ALIEM frontal side are located the 4-buttons keyboard (5), reserved for the use of LSI LASTEM staff, the LEDs that indicate the operating status of the instrument, and the terminal board with removable screw connectors for the connection of sensors, power supply and external devices. -
Page 7: Power Supply
In case of sensors that generate two signals (like the thermo-hygro- metric sensor), it’s suitable to select both inputs that use the same actuator. LSI LASTEM SRL INSTUM_03766 Page 7 / 32... -
Page 8: Differential Mode Inputs
It is preferable to the single-ended mode as it is less subject to electrical noise. The following pictures explain in detail the connections of all types of sensors, both analogue in differential mode and digital. LSI LASTEM SRL INSTUM_03766 Page 8 / 32... -
Page 9: Single-Ended Inputs
The drop resistance, indicated by Rx, is used to return a voltage signal from the current generated by the sensor. Program 3DOM supplies a library for the setting of the LSI LASTEM sensors, including some powered outputs; for such models the settings have been arranged to use the energized scale -300÷1200 mV, thus being able to use 50 Ω... -

The DB9 adapter/terminal block, shown in the figure, is supplied for connecting the RS-485 device. It must be connected as per the following table: Signal D+ / Data+ D-/Data- LSI LASTEM SRL INSTUM_03766 Page 11 / 32...
- Page 12 The configurable parameters are the same as the RS-232 port, namely the Speed, the Network Address and the Flow Control. For more information on changing the parameters, refer to the user manual SWUM_00339. LSI LASTEM SRL INSTUM_03766 Page 12 / 32...

Page 13: Product Installation
For its functioning it requires the dedicated power supply or a photovoltaic module with the proper battery. For the mechanical installation see the documentation provided with the equipment. LSI LASTEM SRL INSTUM_03766 Page 13 / 32... -
Page 14: 3Dom Software
ALIEM – User manual 4 3DOM software 3DOM is the LSI LASTEM’s configuration software for the E/R/M/S-Log, Pluvi-ONE, Alpha-Log and ALIEM in- struments. In Alpha-Log, it allows the user to: • Create and modify the configurations. • Send and receive the configurations through different kinds of connection. -
Page 15: Configuration
If the factory configuration does not suit your usage wish, use the 3DOM software to customize ALIEM. This operation requires the instrument to be connected to a PC with 3DOM software installed (see §4). For more information about the configuration of ALIEM, refer to the 3DOM manual.

Page 16: Use Of Aliem
6.2 Use of the keyboard The keyboard consists in four buttons: two of them are directional and the other two are functional. Its use is reserved for LSI LASTEM personnel. 6.3 Operating status LEDs On ALIEM’s front panel are some LEDs that indicates the instrument operative status: Err/Ok e Tx/Rx. -

2) Data validation: during this operation the value is limited within the scale values allowed by the phys- ical type of measure; 3) Possible thermocouple value correction through the measure of the cold junction temperature (in- ternal temperature of the instrument); LSI LASTEM SRL INSTUM_03766 Page 17 / 32... -

(no divider is required). The anode of diode must be placed on clamp F of terminal board’s entrance and the cathode towards the sensor. LSI LASTEM SRL INSTUM_03766... -
Page 19: Details About Calculated Measures
ALIEM – User manual LSI LASTEM recommended default configuration: • input 9 for wind speed (frequency signal); • input 10 for rain gauge (counter); • input 11 for logical status. 7.5 Details about calculated measures If the instrument has been programmed to process one or more calculated measures, the logical process will be the following: Acquisition of all primary measures that allow the estimate of calculated measures;... -
Page 20: Eolic Alarm
The measure that samples the water level; • The filling-up start time (it’s recommended the automatic filling-up programmed in the morning, before the sunrise, in order to avoid temperature changing that could alter the evaporation measure); LSI LASTEM SRL INSTUM_03766 Page 20 / 32... -
Page 21: Start Precipitation Alarm
To the threshold values can be applied a further hysteresis value; this can avoid continuous alarm state changes in case the measure value moves nearly around the threshold value. The comparison logics are the following: LSI LASTEM SRL INSTUM_03766 Page 21 / 32... - Page 22 4.0 and hysteresis=0.2 (alarm in shaded areas): LSI LASTEM SRL INSTUM_03766 Page 22 / 32...
- Page 23 It can be done applying the algorithm to only one measure (e.g. it isn’t possible to program the minimum times if two or more measures have been selected). LSI LASTEM SRL INSTUM_03766 Page 23 / 32...

Page 26: Maintenance
ALIEM does not require particular maintenance if installed according to what is described in §0. However, it’s recommended that LSI LASTEM staff performs a periodic inspection of the entire system (ALIEM and the sensors connected), in order to detect and fix possible measurement errors. -
