3.4 Manual operation

3. 4 .1 Switching on the device

The device should, as far as possible, always be switched on by putting the toggle switch on the front of the device to posi-

tion 1 (upper). Alternatively this can be done using an external cutout (contactor, circuit breaker) of suitable current capacity.

After switching on, the display will rst show some device related information (model, rmware versions etc.) and then a

language selection screen for 3 seconds. A few seconds later it will show the main screen.

In the Settings menu (also see section

“3.4.3. Conguration via the menu”)

in the group DC input is an option State after

power ON in which the user can determine the condition of the DC input after power-up. Factory setting here is Off, meaning

that the DC input will always be switched off after power-up. Restore means that the last condition will be restored, either on

or off, so the selection here must be considered carefully.

All set values are always saved and restored.

For the time of the start phase the analog interface can signal undened statuses on its digital outputs.

This must be ignored until the device has nished booting and is ready to work.

While manually operated and while also being connected to any remote control equipment via any of

the interfaces, the device could be taken over into remote control anytime without warning or request

for conrmation. It’s thus recommended to block remote control by activating the ‘Local’ mode for the

duration of manual operation.

3.4.2 Switching the device o

The device is switched off be pressing the power switch on the front in position 0 (lower). Doing so will cause two things: a)

the immediate storage of the last condition of the DC output and the most recent set values and b) the occurrence of a PF

alarm (power fail) which can be ignored. The DC output is also immediately switched off and after a certain stopping time (a

few seconds) the display and the fans will go off and then the device is completely powered off.

The power switch on the front cuts the device physically from the AC grid when in position 0. It thus qual-

ies as a separator.

3.4.3 Conguration via the menu

The settings menu is meant for the conguration of all operating param-

eters which are not constantly required. The menu is accessed by nger

touch on the Menu touch area, but only while the DC input is switched

off. See gure to the right.

While the DC input is switched on the settings menu will not be shown,

but some status information.

Menu navigation is also done by nger touch. Inside menus, all values

are adjusted using the numeric pad that pops up when tapping a value.

Many settings are self-explanatory, others are not. Those will be explained

on the pages following.
