MAC-address
In this field the MAC-address of the USM is displayed.
Labelling strips
With click on the button “Print labels” a new window with the labelling strips will be opened. The signal
texts resemble the labelling of the channels, the button texts follow the declaration on the page
“buttons & function inputs”. If a text is too long, it will be displayed in red characters and should be
changed
–
otherwise only the visible part of the text will be printed. By click on a text within the
labelling foil a new dialog for editing of the text will be opened. Please choose DIN A4 landscape
format as paper settings for your printer.
In the table the following parameters can be defined for each signal channel:
Field
Explanation
I
Channelnumber
(fixed assigned)
Signal name
Designation of the respective channel
This designation will be used when printing the labelling strips. A 2-line labelling can
be realised by separating the second line by “
\
” (backslash) from the first line (e.g.
“Bucholtz
\
Alarm”).
OI
Operation indication
If this checkbox is ticked, the signal will be treated as operation indication.
If this box is unchecked (default setting), the signal will be processed according to the
chosen reporting sequence (
page reporting sequence).
By defining the signal to be operation indication or fault annunciation, the LED-colour
will automatically be set according to the settings on the page “LED
-
colour”.
Default settings: operation indication = green, fault annunciation = red.
NC
Normally closed principle of the inputs
(when checkbox is ticked)
Normally open principle: application of a voltage at the input triggers an alarm.
Normally closed principle: voltage drop at the input triggers an alarm.
Default setting: Checkbox not ticked
–
normally open principle.
DT
Debouncing time
The debouncing time defines the timespan for which a signal must continuously be
applied before an alarm is issued. This prevents multiple alarms in the case of a
bouncing switch.
Time 0 ms … 1000 ms, settable in steps of 1 ms
.
RD _|¯ ¯ |_
Response delay
The response delay delays a debounced and defluttered alarm before it is displayed,
forwarded or deleted. This time span is considerably longer than the debouncing time
and can be set from 0 ms … 9h in steps of 1 ms.
The checkboxes _|¯ and ¯ |_ for rising and falling edge define for which signal edge
the alarm delay is active.
_|¯ checked: delay is active for coming alarm
¯ |_ checked: delay is active for receding alarm
DF
The
defluttering
prevents alarms from being triggered and reset permanently e.g. by
a loose contact. The defluttering acts after the response delay (debouncing). If an
input changes more often than the defined number of edges within the fluttering time,
the defluttering comes into effect and the alarm channel is marked as faulty.
This information is only relevant for IEC communication and does not affect
the local display of the annunciator!
Number of edges:
0 … 255
Fluttering time:
0 ms … 65535 ms, ~1 min., in steps of 1 ms
Default settings:
5/100
CR1, CR2,
CR3
Assignment to collective reports
The alarm triggers the collective report which is checked here. Multiple allocations are
possible. All alarms that are assigned to one collective report from a group. This
assignment takes effect for acknowledgement and reset.
