Alarms and monitoring
3.6.1
Definition of terms
There is a clear distinction between device alarms (see
“3.3. Alarm conditions“) such as overvoltage protection
OVP
or over-
heating protection, and user defined events such as
OVD
(overvoltage detection). Whilst device alarms only switch off the
DC output, user defined events can do more. They can also switch off the DC output (
Action
=
Alarm
), but can alternatively
simply give an acoustic signal to make the user aware. The actions driven by
user defined events
can be selected:
Action
Impact
Example
None
User defined event is disabled.
Signal
On reaching the condition which triggers the event, the action
Signal
will show
a text message in the status area of the display.
Warning
On reaching the condition which triggers the event, the action
Warning
will
show a text message in the status area of the display and pop up an additional
warning message which can be noticed from a bigger distance.
Alarm
On reaching the condition which triggers the event, the action
Alarm
will show
an alarm pop-up and additionally emit an acoustic signal, if activated. Further-
more the DC output is switched off. Most of the device alarms are signaled on
the analog interface, while all can be queried via the digital interfaces.
3.6.2
Device alarm and event handling
A device alarm incident will usually lead to DC output switch-off, the appearance of a pop-up in the middle of the display and,
if activated, an acoustic signal to make the user aware. An alarm must always be acknowledged.

How to acknowledge an alarm in the display (during manual control)
1.
If the alarm is currently shown as pop-up, tap
Acknowledge
.
2.
If the alarm has already been acknowledged, but is still displayed in the status area, then
first tap the status area to display the pop-up and then
Acknowledge
.
In order to acknowledge an alarm during analog remote control see
device alarms“. To acknowledge in digital remote control, refer to the external documentation
“Programming guide ModBus & SCPI”.
Some device alarms are configurable:
