Choice of the duration of supply of the probe
If the 4-20 mA probe is to be powered, a duration should be set according to the needs of the probe. By default,
the duration is set at 25 ms which corresponds to the need of the pressure probes provided by Ijinus. For example,
for the inclinometer provided by Ijinus, the duration must be set to 500ms.
Setting the 4-20mA signal conversion:
- Peripheral
: Choose: « 4-20mA input by default (wiring pins 4,3,2 = i, V+, GND)
- Conversion
: Click on the « Off » button to display the green « On » and be able to do the conversion of
the 4-20 mA signal into one of the five possible units: water height (mm), pressure (bar), temperature
(°C), angle (°) or quantify without unit.
For each of the five units, four parameters could be set:
1. Value at 4mA
: the minimum value (in most cases 0) of the sensor connected to the logger
2. Value at 20mA
: the maximum value of the sensor connected to the logger
3. Offset on conversion
: to define if needed for the measure
4. Set a threshold:
It is possible to define a threshold like the following example.
This threshold is based on the Channel 1 conversion and “Rising edge” but you may choose “Falling edge”
for the direction if it is more relevant for your application. The Delay can also be set on activation and/or
deactivation.
An acceleration of the measured frequency is an option you can choose. Define it as active and enter the
new value.
If the data logger has a modem, it is possible to activate an “Anticipated data sending”. It would be based
on the activation and/or deactivation of the threshold.
An output activation is also possible with the activation of the threshold by using the open-drain output.
