Whenever available, connect the ground wire (GND) to terminal 66. If the round wire (GND) isn’t available,
you make sure to connect terminals 60 and 61 (short circuit). This measure will improve the immunity from
electromagnetic noises and the protection from induced and conduced electrical discharges.
WARNING! In case the 31 and 32 terminals feed outside equipments, they must be equipped with power fail
circuit against short circuits or absorbed currents above 1 A.
2.2 Inputs and actuators
The instrument is fitted with 7 actuators used to power the sensors connected to the terminal board, (4
actuators for 8 analogue inputs in differential mode and 16 in single-ended mode, 2 actuators for 4 digital
inputs, 1 actuator for other functions); the actuators can also be used by the actuation programmable logics,
than can produce alarms according to the values acquired by the sensors. The voltage available on these
terminals depends on the kind of power supply received by the instrument.
Use the program 3DOM (see SWUM_00339 available on www.lsi-lastem.com website) to configure the op-
eration to switch on the sensors by means of the switching powers. In order to choose the actuation time is
advisable to consider both the energetic saving and the time the sensor needs to initialize.
The association between input and switching power is fixed, as shown in the table below. The number of the
terminal is indicated in italics; for example, that inputs 1 and 2 both make use of the first actuator; therefore,
it cannot be used for the other inputs. 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.

2.2.1 Differential mode inputs
The differential mode is the one commonly used for the connection of sensors, in which a sensor occupies a
single input.
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.

Fig. 3 –Connection diagram for sensors with analog signal (differential mode).
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 drop resistances.
Fig. 4 –Connection diagram for sensors with digital signal.
2.2.2 Single-ended inputs
Single-ended is a connection mode that allows you to double the number of analog inputs of ALIEM. In this
mode two sensors that have voltageor current signals can be connected to the same input. It is not applicable
to sensors with resistive signals.

Single-ended mode is more subject to electrical noise, therefore the differential mode, in which a sensor
occupies a single input, is preferable when you want to obtain the best measurement performance from the
instrument.
Fig. 5 –Connection diagram for sensors with analog signal (single-ended mode).
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 drop resistances.
When a probe is added using the 3DOM probes library, those sensors are always added in differential mode;
for this reason is not possible add a single-ended probe to a configuration where there is only one single-
ended sensor free; when this situation occurs set the measure parameters manually matching the single-
ended probe needs; otherwise change, if possible, different measures from differential to single-ended mode
until obtaining a complete differential input free (two single-ended sequential inputs).
2.3 Serial ports
MDMMB1110 is fitted with two RS-232 serial ports through 9-pole female standard connectors (DB9F).
Serial port 1 (2) (located on the left-hand side panel, at the bottom near the terminals) is used to program
the instrument's operative modes and data download, by means of the LSI CISS communication protocol.

6Use of ALIEM
6.1 Start-up/Shutdown
Start-up and shutdown are controlled by the On/Off switch (1).
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.
Err/Ok
These LEDs determine the operating status of the instrument. In particular:
-Err: it is red; if on it indicates the presence of an error in the instrument
-Ok: it is green; it has the following meanings:
ooff: instrument switched off, or low feeding voltage (min. 7 V)
osingle quick blinkings: instrument switched on; regular operation (acquisition mode)
othree quick blinkings: instrument switched on; it operates in reconfiguration mode
ofive quick blinkings: the instrument is on; it operates in quick acquisition mode (reserved for
the use of LSI LASTEM staff)

7Insight ALIEM
7.1 Acquisition and calculation of measures
It is possible to acquire measures of sensors with a rate from 1 second to 12 hours; this allows a better
representation of both fast-changing quantities (wind speed), as well as slow-changing ones (air tempera-
ture). It is possible to acquire as many as 10 measures per second.
For sensors which have to be powered, ALIEM is fitted with own outputs with switched power supply (see
“actuators”§2.2).
The instrument is able to calculate quantities deriving from measures that sample the signs from the inputs:
ALIEM is fitted with a calculation library dedicated to environmental applications, also able to carry out useful
mathematical functions (see §0). ALIEM is able to acquire and calculate up to a maximum of 99 total
measures. Furthermore, it’s possible to program some calculated measures according to the data generated
by other calculated measures.
Program 3DOM can be used to program the measure sampling sequence: the program interface allows
choosing the sequence in which the measures are displayed; hence which is the sampling sequence taking
place during the survey. With 3DOM you can also set automatically the measure sequence according to their
acquisition rate (from the shortest to the slowest). This is important to gather measures which, during the
acquisition process, must be sampled within the shortest intervals possible among each other (if they are
allocated to only one actuator).
If configured with the same acquisition rate, the analogue channels following the first one will be sampled
about 80 ms after the previous channel. This means that as many as eight analogue channels are sampled
within a total time of 700 ms. Digital channels are instead sampled almost instantly.
7.2 Acquisition from thermocouples
ALIEM is able to acquire the signals from many types of thermocouples. The instrument uses the internal
temperature value as reference of value of the cold junction.In these cases it is necessary to program, by
means of the 3DOM program, the measure of the internal temperature. The measure of the internal tem-
perature must precede, in the measure sequence, all measures of quantities which use such reference.
7.3 Details about the measure acquisition process
The sampling of the signals produced by the sensors connected to the instrument's terminal board takes
place according to the following logical procedure:
1) Measurement of the electrical signal based on its type (voltage, resistance, frequency, etc.) and its
digital conversion into a 16-bit numeric value; the physical type of the sensor is programmed through
parameter Electrical measure type;
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);

ALIEM –User manual
LSI LASTEM SRL
INSTUM_03766
Page 18 / 32
4) Linearization of non-linear signals based on the setting of parameter Linearization type; the lineari-
zation may also take place through the setting of a polynominal function whose factors are specified
until 10° degree (section Linear parameter of 3DOM);
5) Recalculation of the value according to numeric parameters defined in section Parameters:
•Computation of the measured quantity through the defined initial and final scale values;
•Application of the calibration factor of the specific used sensor (radiometers, rain gauges, etc.);
•Selection of the logical state with reference to the analogue signal thresholds;
•Measure validation after processing accompanied by error indication if greater (by 0.5%) than
the limits set in output; wind direction and relative humidity are excluded;
•Linearized quantity control: the instrument produces null output when receiving null input.
All above parameters are indicated in section Measure properties in the measure modification window of
program 3DOM.
7.4 Acquisition from status signal
ALIEM is able to acquire different types of digital status; they have to be configured for their connection to
9, 10, 11 and 12 inputs.
Ther are 3 different signal types: frequency signals, digital status and counters.
The default configuration of acquirer has been made for:
give logical status = 1
In case of short circuit or 0 V
give logical status = 0
In case of opened contact or 3 V
Furthermore, if one configuration for low power consumption is selected:
•for signals with frequencies over 1000 Hz it’s better the input 9;
•for signals with frequencies under 1000 Hz, for counters and logical status they’re better the inputs
11 and 12;
•do not configure the input 10 because it doesn’t reduce the instrument’s low power consumption.
If it’s been selected one configuration with no attention to power consumption:
•for signals with frequencies over 1000 Hz use the inputs 9 and 10;
•for signals with frequencies under 1000 Hz and for logical status use any inputs among the available
ones.
The sensors with status output that produce voltage (e.g. they aren’t pure contacts “open/closed”) but with
variable voltage according to measured status, can be connected to ALIEM through one diode; in this way
every connection is always the right one, apart from the output voltage (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.

ALIEM –User manual
LSI LASTEM SRL
INSTUM_03766
Page 19 / 32
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:
1) Acquisition of all primary measures that allow the estimate of calculated measures; a calculated
measure can be a primary measure for new calculated measure;
2) Collection of the value of primary measures; if at least one of these values is found to be in error,
its calculated measure will also be indicated in error;
3) Collection of the value of standard parameters, whenever used in the calculation; the value of these
parameters is decided during the configuration process and cannot therefore be modified during
the survey;
4) Execution of the estimate;
5) Allocation of the calculated value to the measure's instant datum.
The acquisition rate of a specific calculated measure is setted by 3DOM so that it may correspond to the
acquisition rate smaller than the calculated measures it depends on.
7.6 Actuation logics
ALIEM has got an actuation logics library. It’s useful to switch-on all type devices (alarms, solenoid valves,
motors) according to the surveyed parameters in surrounding environment. The actuation logics are based
on the instantaneous value of the acquired and calculated measures. They can be programmed up to 20
calculation algorithms, that use same or different logics. One or more algorithms can be combined in two
differed modes, in order to switch-on the selected actuator:
1) All algorithms must be in alarm at the same time (AND logic);
2) One algorithm can be in alarm at least (OR logic).
The actuator’s switch-on logic can operate according to low power consumption mode (the actuator is usually
deactivated, and starts in case of alarm), or according to safety mode (the actuator is usually activated, and
it shuts-down in case of alarm). Summarizing explanation in the table below.

Page 20 / 32
In case of one or several measures’ error (for example owing to sensor breaking, no-scale acquisition, or
disconnected cable) it doesn’t modify the present state of the actuator piloted by the logic that uses the
same measures.
The actuation logic deactivates the actuator only if it has previously activated from the logic itself.
The actuation logic begins operation after the first activation of the actuator, even if this occurs temporally
after the deactivation.
The programming of the actuation logics happen by means of the 3DOM program according to two different
phases:
1) Selection of the logics and their calculation parameters (section Logics);
2) Selection of the actuation outputs and their AND or OR modes correlation with the preset logics
(section Actuators); note that the same logic can be combined with other different logics several
times, in order to switch over different effectors.
7.6.1 Eolic alarm
The logic uses a wind direction measure to establish the condition of a wind position in a specified sector for
a predefined time. Can be set:
•The measure that samples wind direction (degrees);
•The starting angle (extreme included) of the direction sector;
•The ending angle (extreme included) of the direction sector;
•The continuous permanence time of the wind direction inside the defined sector in order to detect
the alarm condition;
•The continuous permanence time of the wind direction outside the defined sector in order to detect
the end of the alarm condition.
Both times can be set from 0 seconds to 12 hours; if both times are set to zero, the wind direction in or out
conditions inside the sector are immediately detected.
It is possible to join this logic with an another logic of threshold bypass type (see §7.6.5) applied to a wind
speed measure: in this way it’s possible to refine further the alarm activation (e.g. to activate the alarm when
the wind is more than 5 m/s for at least 3 minutes and inside the Est sector of 45 degree for at least 1 minute).
7.6.2 Evaporimeter filling
The logic uses a water level probe inside the evaporimeter to establish the need for filling up it.
It can be set:
•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);
