3.5.7
Switching the DC terminal on or off
The DC terminal of the device can be manually or remotely switched on and off. After the DC terminal has been
switched on, it can either work as a DC input (sink mode) or DC output (source mode). More information can be
found in
“3.3.6. Sink-source mode switching”
.
Switching the DC terminal on during manual operation or digital remote control can be disabled
by pin REM-SB of the built-in analog interface. For more information refer to 3.5.3.1 and ex-
ample a) in
3.6.4.7.
► How to manually switch the DC terminal on or off
1.
As long as the control panel is not completely locked press the button
On/Off
. Otherwise you are asked to
disable the HMI lock. In case the HMI lock is connected to a PIN, you are asked to enter the PIN first.
2.
With the possible HMI lock removed, button
On/Off
toggles the DC terminal state, as long as this is not
restricted by an alarm or the device being in remote control.
► How to remotely switch the DC terminal on or off via the analog interface
1.
See section
““3.6.4. Remote control via the analog interface”.
► How to remotely switch the DC terminal on or off via the digital interface

See the external documentation “Programming Guide ModBus & SCPI” if you are using custom software,
or refer to the external documentation from LabVIEW VIs or other software provided by the manufacturer.
3.5.8
Recording to USB stick (logging, standard models)
Device data can be recorded to USB stick (USB 3.0 is supported, but not all memory sizes) anytime. For specifi
-
cations of the USB stick and the generated log files refer to section
“1.9.6.5. USB port (front side)”
.
The logging stores files of CSV format on the stick where the layout of the log data is the same as when logging
via PC with software EA Power Control. The advantage of USB logging over PC logging is the mobility and that
no PC is required. The logging feature just has to be activated and configured in the Settings.
3.5.8.1
Configuration
Also see section
3.5.3.6
. After USB logging has been enabled and the parameters
Logging interval
and
Start/
Stop
have been set, logging can be started anytime from within the Settings menu or when switching the DC
terminal on, all depending on the selected start/stop mode.
Furthermore see section
3.5.3.1
. There are additional settings for the CSV file itself as generated by the USB
logging features. You can switch the column separator format between german/european standard (
Default
) or US
american standard (
US
). The other option is used to deactivate the physical unit that is added by default to every
set/actual value in the log file. Deactivating this option simplifies the CSV file processing in MS Excel or similar tools.
3.5.8.2
Handling (start/stop)
With setting
Start/stop
to
At DC on/off
logging will start
each time the DC terminal of the device is switched on, no
matter if manually with the front button
On/Off
or remotely
via analog or digital interface. With setting
Manual
it’s
different. Logging is then started and stopped only in the
quick menu (see figure to the right).
Button
starts logging manually and changed to
, which is for manual stop.
Soon after logging has been started, the symbol
indicates the ongoing logging action. In case there is an error
while logging, such as the USB stick is full or removed, it will be indicated by another symbol (
). After every
manual stop or switching the DC terminal off the logging is stopped and the log file closed.
