Some features are available depending on the firmware version (if you have a previous version please contact us in order to upgrade the unit)

- SMS alarms and control since firmware 4.0.0

- Script Programing since firmware 5.0.0

You must select if the analog inputs will be of the 0-10V or 4-20 mA type with the internal jumpers of the equipment. Disassemble carefully and place the jumpers as indicated in the figure. You will also have to configure the GRD from the configuration software indicating the type of inputs you are using. AN1 can also be configured to connect a PT100 temperature sensor.

Connect PT + to terminal 8 (AN1) and PT- to terminals 9 and 10 (AGND)

Disassemble carefully and place the jumpers as indicated in the figure. For PT100 no matter in what state is the Tension/Current jumper.

Wiring – Digital Inputs/Outputs Jumpers

Terminal 3 and 4 can be configured as digital inputs or outputs, acording to the jumpers configuration.
