3.4
Manual operation
3.4.1
Switching on the device
The device should, as far as possible, always be switched on using the toggle switch on the front of the device.
Alternatively, this can be done using an external cutout (contactor, circuit breaker) of suitable current capacity.
After switching on, the display will first show some device related information (model, firmware versions etc.) and
then a language selection screen for 3 seconds. A few seconds later it will show the main screen.
In setup (see section
„3.4.3. Configuration via MENU“
General settings
” is an option
“
Output after power ON
” in which the user can determine the condition of the DC output after power-up. Factory
setting here is “
OFF
”, meaning that the DC output on power-up is always switched off. “
Restore
” means that the
last condition of the DC output will be restored, either on or off. All set values are always saved and restored.
For the time of the start phase the analog interface can signal undefined statuses on the output
pins such as ERROR or OVP. Those signal must be ignored until the device has finished boot
-
ing and is ready to work.
3.4.2
Switching off the device
On switch-off the last output condition and the most recent set values are saved. Furthermore, a PF alarm (power
failure) will be reported, but can be ignored.
The DC output is immediately switched off and after a short while fans will shut down and after another few seconds
the device will be completely powered off.
3.4.3
Configuration via MENU
The MENU serves to configure all operating parameters which
are not constantly required. These can be set by finger touch on
the MENU touch area, but only if the DC output is switched OFF.
See figure to the right.
If the DC output is switched on the settings menu will not be shown,
only status information.
Menu navigation is by finger touch. Values are set using the rotary
knobs. The assignments of the rotary knobs, if multiple values
can be set in a particular menu, is not always depicted. Following
rule for such situations: upper value -> left knob, lower value .>
right knob.
The menu structure is shown schematically on the following pages.
Some setting parameters are self-explanatory, others are not. The
latter will be explained on the pages following.
