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. This can be restricted in manual
operation by the control panel being locked. After switching it on, it either works as input (sink mode) or 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 disa-
bled by pin REM-SB of the built-in analog interface. For more information refer to
3.5.3.1 and
example 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 fully locked press the button
On/Off
. Otherwise you are asked to disable
the HMI lock first.
2.
This button toggles between DC terminal on or off, as long as a change is not restricted by an alarm or the
device being locked in “remote”.
► 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 (AI)“ on page 63.
► How to remotely switch the DC terminal on or off via the digital interface
1.
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.

Recording to USB stick (logging)
Device data can be recorded to USB stick (2.0 / 3.0 may work, but not all vendors are supported) anytime. For
specifications 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. 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 MENU.
3.5.8.1
Configuration 1
Also see section
. 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 MENU or after leaving it, depends on the
selected start/stop mode.
3.5.8.2
Configuration 2
. There are additional settings for the CSV file itself as generated by the USB logging feea
-
tures. 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 values
in the log file. Deactivating this option simplifies the CSV file processing in MS Excel.
3.5.8.3
Handling (start/stop)
With setting “
Start/stop with DC terminal 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 start/stop
” it is different. Logging is then started and stopped only in the MENU, in the logging
configuration page.
Soon after logging has been started, the symbol indicates the ongoing logging action. In case there is an error
while logging, such as USB stick 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.
