8.9. 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 models, proper connectors are provided for this purpose.
The case cover should be opened only if necessarily required. If this is the case, the cover must be properly tightened back in
its place such as to assure the stated IP Ingress protection index.
Parameter
Function
TAG
Defines a name (up to 8 characters) for identifying the variable to be measured in the channel
Inputs
The signal applied to the logger 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 jumpers J1 and J2.
For more information refer to section 7 electrical connections
Unit
Defines the variable unit
Scale
Defines the range, in engineering units, to represent 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 types the scale is fixed.
Offset
Allows fine offset corrections on the measured value
Value
Defines readings recording modes:
Instantaneous
The instant value read at the logging time
Average
10 equidistant readings at each reading interval are taken.
The average value of readings is built and the resulting value
recorded
Minimum
10 readings at each reading interval. The lowest value found
is recorded
Maximum
10 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, till a new
configuration is applied to the logger.
Low
Defines the minimum value under which the alarm
is triggered
High
Defines the maximum value above which the alarm is
triggered
After filling all the fields for both channels, send the configuration to the logger by clicking on the button
The new settings and PC current date/time are then sent to the logger. All Data in the logger memory will be lost.
The parameters are:
