PSI 9000 DT Series
These device alarms can’t be configured and are based on hardware:
Alarm Meaning Description Indication
PF P ower F ail
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 which could be only temporarily, depending on the situa -
tion and setting “DC output after PF alarm” (see
3.4.3.1
).
Display, analog &
digital interface
OT
O ver T em-
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 after OT alarm” (see
3.4.3.1
).
Display, analog &
digital interface
► How to configure the device alarms
1.
While the DC output is switched off tap touch area on the main screen.
2.
On the right side tap the down arrow to select “ 2. Protection ”.
3.
Set the limits for the device 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 on 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 off tap touch area on the main screen
2.
In the menu page, tap “ HMI Setup”
3.
In the following menu page, tap “ Alarm Sound”
4.
In the settings page select “
Sound on
“ or “
Sound off
” and confirm with .
3.6.2.1 User defined events
The monitoring functions of the device can be configured for user defined events. By default, events are deactivated
(Action = NONE). Contrary to device alarms, the events only work while the DC output is switched on. It means,
for instance, that the device can’t 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.

These events are not to be confused with alarms such as OT and OVP which are for device
protection. User defined events can, however, if set to action ALARM, switch off the DC output
and thus protect the load, like a sensitive electronic application.
