3.6 Alarms and monitoring
3.6.1 Denition of terms
There is a clear distinction between device alarms (see “3.3. Alarm conditions” ), such as overvoltage protection OVP or over-
heating protection OT, and user dened events such as OVD (overvoltage detection). Whilst device alarms only switch off
the DC input, user dened events can do more. They can also switch off the DC input(Action = Alarm), but can alternatively
simply give an acoustic signal to make the user aware. The actions driven by user dened events can be selected:
Action Impact Example
None User dened 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
a text message in the status area of the display with an additional alarm pop-
up, and additionally emit an acoustic signal (if activated). Furthermore the DC
input 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 input 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 indicated as a pop-up, tap Acknowledge.
2. If the alarm has already been acknowledged, but is still displayed in the status area, then
rst tap the status area to display the pop-up and then Acknowledge.
In order to acknowledge an alarm during analog remote control refer to “3.5.4.2. Acknowledging device alarms” . To acknowl-
edge in digital remote control, refer to the external documentation “Programming Guide ModBus & SCPI”.
Some device alarms are congurable:
Short Long Description Range
Indication
OVP OverVoltage
Protection
Triggers an alarm as soon as the voltage on the DC input
reaches the dened threshold. The DC input will be switched
off.
0 V...1.1*U
Nom
Display, analog &
digital interfaces
OCP OverCurrent
Protection
Triggers an alarm as soon as the current in the DC input reach-
es the dened threshold. The DC input will be switched off.
0 A ...1.1*I
Nom
Display, analog &
digital interfaces
OPP OverPower
Protection
Triggers an alarm as soon as the input power reaches the
dened threshold. The DC input will be switched off.
