LogBox-AA Datalogger
NOVUS AUTOMATION
3/7
After a defined number of readings: The logger will stop logging after
the number of readings here defined is reached. Not valid when the
option ‘Daily Repetition’ is selected.
Day / Hour:
The
LogBox-AA
will stop logging at the user-defined
date and time. Not valid when the option ‘Daily Repetition’ is
selected.
CHANNELS FIELD
By selecting the “
Channels”
option, the user is able to choose the
individual settings for each input channel, as
Fig. 7
shows.
Fig. 7
– Parameters for Input Channels Configuration
Such parameters are:
Tag:
Defines a name (up to 8 characters) for identifying the variable
to be measured.
Inputs:
The signal applied to the logger second input is defined here.
The list shows all the input options available. The selected option
must be in accordance with the internal configuration of the jumper,
as
Table 1
shows.
Unit:
Defines the variable unit.
Scale:
Defines the range, in engineering units, for representing the
input variable measured.
Adjustable from –32000 to +32000 for
4-20 mA, 0-20 mA, 0-50 mV
and 0-10
inputs, for the remaining input times the scale is fixed.
Offset:
Allows fine offset corrections on the measured value.
Value:
Defines readings recording mode:
Instantaneous:
The instant value read at the logging time.
Average:
Ten readings at each reading interval. The average
value of readings is the value recorded.
Minimum:
Ten readings at each reading interval. The lowest
value found is recorded.
Maximum:
Ten readings at each reading interval. The
highest value found is recorded.
Alarm:
defines a limit range of variables measured that, once
exceeded, trigger the alarm.
Once activated, the alarm LED indicator stays so even after the
alarm-triggering situation has ceased.
LOW defines the minimum value under which the alarm is triggered;
HIGH defines the maximum value above which the alarm sensor is
triggered.
After filling all the fields, send the configuration to the logger by
clicking on the button
New settings and PC current date/time are then sent to the logger.
ELECTRICAL CONNECTIONS
Only the input connections and the External Battery Switch (when
used) are needed. The logger is exclusively powered by its internal
battery.
In the IP65 models, the inputs and the signal for activating the
external power supply are located inside the logger case, which must
be opened for accomplishing the connections.
In the IP67 model, proper connectors are provided for this purpose,
as shown in
Fig. 9
.
IP65 MODEL
Open the logger’s cover to get access to the block terminals and the
configuration jumpers. Connection cables must pass through the
compress fitting located at the bottom of the case.
Fig. 8
shows the
internal terminals distribution.
Channel 1:
CN1 connector – Terminals 1, 2 and 3
Channel 2:
CN1 connector – Terminals 4, 5 and 6
External Battery Switch
CN2 connector – Terminals 7, 8 and 9
Digital Input
CN2 connector – Terminals 7, 10 and 9

Note: Make sure that the compress fitting is perfectly tightening the
cables, thus assuring proper IP65 protection: (totally dust-tight and
protected against water jets).
IP67 MODEL
In the IP67 version, an M8 connector is provided for signal input. Two
connectors provide external access to the input channels, as shown
in
Fig. 9
. The cables are supplied with the logger.
Note: The case cover should not be opened unless battery
replacement is required. If this is the case, the cover must be
properly tightened back in its place such as to assure the IP67
protection.
IP67
- Totally dust-tight and protected from temporary immersion
in water.
