3.6 Device alarm 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 “3.5.4.2. Acknowledging
device alarms“. To acknowledge in digital remote control, refer to the external documentation
“Programming guide ModBus & SCPI”.
Some device alarms are configurable:
Short Long Description Range Indication
OVP O ver V oltage
P rotection
Triggers an alarm as soon as the DC output voltage reaches the OVP
threshold. The DC output will be switched off.
0 V...1.1*U
Nom

log & digital

OCP O ver C urrent
P rotection
Triggers an alarm as soon as the DC output current reaches the OCP
threshold. The DC output will be switched off.
0 A...1.1*I
Nom
OPP O ver P ower
P rotection
Triggers an alarm as soon as the DC output power reaches the OPP
threshold. The DC output will be switched off.
0 W...1.1*P

These device alarms can’t be configured and are based on hardware:
Short Long Description Indication
PF P ower F ail AC supply over- or undervoltage. Triggers an alarm in case 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 terminal will be switched off. The condition of the
DC terminal after a temporary PF alarm can be determined by the setting DC output
-> State after PF alarm .

log & digital
interface
Acknowledging a PF alarm during runtime can only occur approx. 15 seconds after
the cause of the alarm has gone. Switching the DC output on again requires another
approx. 5 seconds of waiting time.
OT O ver Tem-
perature
Triggers an alarm if the internal temperature reaches a certain limit. The DC output
will be switched off which could be only temporarily, depending on the setting DC
output -> State after OT alarm (see 3.4.3.1).

MSP M aster- S lave
P rotection
Triggers an alarm if the master unit loses contact to any slave unit. The DC output
will be switched off. The alarm can be cleared by reinitializing the MS system or de-
activating master-slave mode.

O ver V oltage
P rotection
Only featured with the 60 V model:
Triggers a special OVP alarm when the voltage on the DC output exceeds the rigid
threshold of 101% rated voltage. The DC output will be switched off. For details refer

SF S hare Bus
F ail
Can occur in situations where the Share bus signal is damped too much due to wrong
or damaged (short-circuit) BNC cables or simply when at least one of the Share bus
connectors is wired to another device while the device reporting the isn’t (yet) con-
figured for master-slave operation. For details also see 3.3.7.
