Switching the DC output on or off
The DC output 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.
Switching the DC output on during manual operation or digital remote control can additionally
be blocked by pin REM-SB of the built-in analog interface. For more information refer to
and example a) in 3.5.4.7.

As long as the control panel isn’t fully locked press the button ON/OFF. Otherwise you are asked to disable
the HMI lock first.

3.4.10
Recording to USB stick (logging)
Device data can be recorded to USB sticks of standard 2.0 or 3.0 (not all chip vendors are supported) anytime.
For specifications of the USB stick and the generated log files also refer to section
„1.9.5.5. 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.
3.4.10.1
Configuration
. 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.
3.4.10.2 Handling (start/stop)
With setting “
Start/stop with DC output ON/OFF
” logging will start each time the DC output 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’s different. Logging is then started and stopped only in the MENU, specifically 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 a different symbol (
). After every manual
stop or switching the DC output off the logging is stopped and the log file closed.
3.4.10.3
Log file format
Type: text file in european or US CSV format, depending on the setting “USB file separator format” (see
