SIGNALS VIA LED ON FRONT PANEL
| LED | STATUS | LED meaning |
|---|---|---|
| PWR/COM Green | ON | The device is powered correctly |
| PWR/COM Green | Flashing | Communication via USB port |
| D-OUT Yellow | ON | Digital output activated |
Assembly
The device can be mounted in any position, in compliance with the expected
environmental conditions. Use the accessories supplied for fixing on a DIN
rail. Attention: magnetic fields of considerable magnitude can alter the
measurement: avoid proximity to permanent magnetic fields, solenoids or
ferrous masses which induce strong alterations of the magnetic field;
possibly, if the zero error is greater than the declared error, try a
different arrangement or change orientation.
Attention
Pay attention to the direction of current flow during installation. To
increase current measurement sensitivity, insert the cable multiple times into
the central hole of the instrument to create coils. Sensitivity is
proportional to the number of turns. Please, install the module as shown in
the figure. Pay attention to the direction of the current flow. To increase
the current measurement sensitivity, insert the cable several times into the
central hole of the instrument, creating a series of coils. The current
measurement sensitivity is proportional to the number of turns

USB PORT
The module is designed to exchange data according to the modes defined by the
MODBUS protocol. It has a micro USB connector on the front panel and can be
configured using applications and/or software programs. The USB serial port
uses the following communication parameters: 38400,8,N,1 The USB communication
port responds exactly like the serial ports, with the exception of the
communication parameters. For more information, visit the site shown on page 1
