Parameterization
In the table the following parameters can be defined for each signal channel:
Field name
Explanation
K
Channel number
(firmly specified)
I
Input terminal
(firmly specified)
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 (
tab 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
(on checking the box)
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 alarm delay delays a permanently pending alarm (debounced and monitored for
flutter) before it is processed. This is intended to suppress error alarms that would
occur, for example, if a value is only briefly exceeded or underrun. The time span is
significantly greater than the response delay (debouncing time). The time span goes
from 0...32400 s (9 h) and is definable in two grids (value < 30 s in a
1 ms grid and for values > 30 s in a 1 s grid).
The value can be entered in three formats:
1. pure numerical value e.g. 100 interpretation in seconds
100 s
2. .xxx e.g. .100 interpretation in ms
100 ms
3. mmm:ss.xxx interpretation in minutes, seconds and milliseconds
e.g. 111:22.0
111 minutes and 22 seconds
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.
Number of edges:
0 … 255
Fluttering time:
0 ms … 65535 ms, ~1 min., in steps of 1 ms
Default settings:
5/100
