3.4.10.1 Conguration
Also see section 3.4.3.7. 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 input ON/OFF” logging will start each time the DC input 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conguration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

• With setting “Start/stop with DC input ON/OFF”, the logging will also stop on alarms or events with action
“Alarm”, because they switch off the DC input
• With setting “Manual start/stop” the device will continue to log even on occurring alarms, so this mode can be
used to determine the period of temporary alarms like OT or PF
