•
For each command the following input command parameters can
individually be configured and modified from the default settings:
Tx Input Delay
,
Tx Input Prolongation
,
Max Tx Trip Duration
.
Note:
Pickup times for link and user alarms must be set to
values higher than the configured max Tx Trip
Duration.
•
By checking the corresponding box it can be selected for each
command independently whether the
Max Rx Trip Duration
shall
be monitored (if checked, the parameter for the max duration can
be modified from its default value).
Note:
Pickup times for link and user alarms must be set to
values higher than the configured max Rx Trip
Duration.
•
By activating a radio button it can be chosen whether all
commands are actuated at the outputs as long as the
corresponding tripping signal is received and eventually
prolongated (radio button
Rx Output prolongation
) or whether all
commands are actuated for a fixed duration only, irrespective of
the length of the received tripping signal (radio button
Rx Output
Duration
). In both cases the parameters can be modified from its
default values for each command individually.
•
Either the
ETL pilot
can be selected or a special NSD600
Guard
signal
can be used. The frequency of the NSD600 own guard
signal depends on the speech bandwidth entered under
Configure
telephony
. Possible values for the speech bandwidth are 2000,
2200 or 2400 Hz. For a speech bandwidth of 2600 Hz and higher,
the NSD600 must use the ETL pilot as guard signal.
•
Furthermore on these tabs the
Boost ratio
can be selected
(depends on the configured and disconnectable services), the
Cyclic loop test
can be enabled and the
Loop test interval
can
be determined (1, 3, 6, 12 or 24 hours).
Note:
It is recommended to finish configuration of all the
other services before the NSD600 boost ratio is set
(in order to let the HMI600 determine the max.
possible boost ratio that can be programmed).
Note:
Per default the box
Auto select max
is checked in
the frame
Power boosting
This means that the
maximal possible boost ratio is used for the tripping
signals. By un-checking the box, a pull-down menu is
enabled and a lower boost ratio can be chosen.
Remarks for the tabs
Supervision TPE 1 / Supervision TPE 2:
•
In the frame
Unblocking
the
Threshold
, the
Extra delay
and the
Pulse duration
can be modified from the default settings.
