AC supply over- or undervoltage. Triggers an alarm if the AC supply is
out of specification or when the device is cut from supply, for example
when switching it off with the power switch. The DC output will be
switched off.

rotection
Triggers an alarm if the master of an initialised master-slave system
loses contact to any slave unit or if a slave has not yet been initialised
by the master. The DC output will be switched off. The alarm can be
cleared by either deactivating master-slave mode or reinitialising the
MS system.

► How to configure the device alarms
1.
While the DC output is switched tap the touch area
on the main screen.
2.
On the right side tap the down arrow to select “
2. Protect
”.
3.
Set the limits for the equipment alarm relevant to your application if the default value of 110% is unsuitable.
The set values can be entered using the ten-key tab. This will appear by tapping the touch area
“Direct input”.
The user also has the possibility of selecting whether an additional acoustic signal will be sounded if an alarm or
user defined event occurs.
► How to configure the alarm sound (also see “
„3.4.3. Configuration via MENU“
)
1.
While the DC output is switched tap the touch area
on the main screen
2.
In the menu page, tap “
HMI Settings”

User defined events
The monitoring functions of the device can be configured for user defined events. By default, events are deac
-
tivated (action = NONE). Contrary to device alarms, the events only work while the DC output is switched on. It
means, for instance, that you cannot detect undervoltage (UVD) anymore after switching the DC output off and
the voltage is still sinking.
The following events can be configured independently and can, in each case, trigger the actions NONE, SIGNAL,
WARNING or ALARM.
