Resolution of the displayed values
In the display, set values can be adjusted in fixed increments. The number of decimal places depends on the device
model. The values have 4 or 5 digits. Actual and set values always have the same number of digits.

USB port (front side)
The frontal USB port, located to the right of the rotary knobs, is intended for the connection of standard USB sticks
and can be used for loading or saving sequences for the arbitrary and the XY generator.
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 not 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 types from a stick:
File name
Description
Section
wave_u<arbitrary_text>.csv
wave_i<arbitrary_text>.csv
Function generator for an arbitrary function on voltage (U) or cur
-
rent (I) .The name must begin with
wave_u / wave_i
, the rest is
user defined.
profile_<arbitrary_text>.csv
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.
pv<arbitrary_text>.csv
fc<arbitrary_text>.csv
PV or FC table for the XY function generator.
The name must begin with
pv
or
fc
, the rest can be user defined.
pv_day_et_<arbitrary_text>.csv
pv_day_ui_<arbitrary_text>.csv
Day trend data file to load for the simulation modes DAY I/T and
DAY U/I of the extended PV function.
iu<arbitrary_text>.csv
ui<arbitrary_text>.csv
IU or UI table for the XY function generator.
The name must begin with
iu
or
ui
, the rest can be user defined.
The control panel of the device can save the following file types to an USB stick:
File name
Description
Section
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 auto
-
matically counted up if equally named files already exist in the folder.
profile_<nr>.csv
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.
wave_u_<nr>.csv
wave_i_<nr>.csv
Sequence point data (here: sequences) of either voltage U or
current I from arbitrary function generator
pv_record_<nr>.csv
Data from the data recording option in the extended PV function
according to EN 50530.
