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 deter-
mined by the setting
DC terminal -> State after PF alarm
.

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.

Triggers an alarm in case the internal temperature reaches a certain limit. The
DC terminal will be switched off. The condition of the DC terminal after cooling
down can be determined by the setting

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 alarm report-

How to configure the thresholds of the adjustable device alarms
1.
While the DC terminal is switched off tap the touch area
on the main screen.
2.
In the menu tap on group
Protection
. On the right-hand side of the screen it will list all device alarms with their adjustable
thresholds. These are permanently compared to the actual values of voltage, current and power on the DC terminal.
Here is also distinguishes between source and sink mode.
3.
Set the threshold for the protections relevant to your application if the default value of 110% is unsuitable.
The user also has the possibility of selecting whether an additional acoustic signal will be sounded if an alarm or user defined
event occurs.
