1.9.5.5 USB-Port (Front side)
The frontal USB port, located below the LED “Power”, is intended for the connection of standard USB sticks. This
can be used for data recording during all operation modes.
USB 2.0 sticks are accepted and must be
FAT32
formatted and have a
maximum capacity of 32GB
. USB 3.0
sticks also work, but from all manufacturers. All supported files must be held in a designated folder in the root path
of the USB drive in order to be found. This folder must be named
HMI_FILES
, such that a PC would recognise
the path G:\HMI_FILES if the drive were to be assigned the letter G.
The control panel of the device can read the following file formats from an USB stick:
profile_<nr>.csv
Previously saved user profile. The number in the file name is a counter and not
related to the actual user profile number in the HMI. A max. of 10 files to select
from is shown when loading a user profile.
The control panel of the device can save the following file formats to an USB stick:
profile_<nr>.csv
User profile. The number in the file name is a counter and not related to the actual
user profile number in the HMI. A max. of 10 files can be stored by in the folder.
usb_log_<nr>.csv
File with log data recorded during normal operation in all modes. The file layout
is identical to the those generated from the Logging feature in EA Power Control.
The <nr> field in the file name is automatically counted up if equally named files
already exist in the folder.
1.9.6 USB port (back side)
The USB-B port on the back side of the device is standard
with this series and is provided for communication with the
device and for firmware updates. The included USB cable
can be used to connect the device to a PC (USB 2.0 or 3.0).
The driver is delivered on the included USB stick and installs
a virtual COM port. Details for remote control can be found on
the included USB stick or the web site of Elektro-Automatik.
The device can be addressed via this port either using the
international standard ModBus protocol or by SCPI language.
The device recognises the message protocol automatically.

If remote control is going to be activated, the USB interface has no priority over any other interface and can there-
fore only be used alternatively to them. However, monitoring is always available, no matter if and via what interface
the device is remotely controlled.
1.9.7 “Sense” connector (remote sensing)
In order to compensate for voltage drops along the DC cables to the load, the
Sense
input (between
the DC output terminals) can be connected to the load. The device will automatically detect when
the sense input is wired (Sense+) and compensate the output voltage accordingly.
The maximum possible compensation is given in the technical specifications.
