LON fire damper actuator 4 ports
Order No.: 421 404 / 421 405
checked cyclically every 100 milliseconds and when the end position switches
are changed. The following states can be read in the status:
FSDA state
(bit set)
Meaning
self_test_in_progress Maintenance run is performed, is reset at the end of
maintenance
fail_self_test
Maintenance run was not completed successfully
mechanical_fault
Damper has not moved after the run command or
the 1.5-fold run time has been exceeded, the
direction can be recognized via the fields over_range
and under_range
over_range
Exceeding the travel time when moving into
protection position
under_range
Exceeding the travel time when driving in normal
position
comm_failure
Overrun of the receive time on nviDriveValue or
nviGroupValue if the respective SCPTmaxRcvTime is
not 0
in_alarm
Protection position taken with unknown cause
(analog to nvoFire)
The status display should be reset via the telegram {EMERG_CLEAR_STATUS}
after the error causes have been eliminated.
Fire alarm
In addition to the described status display, the network output variable
nvoFire can be used to directly display an existing fire alarm. It signals fire
(100,0 1) as soon as the normal position is left without this behaviour being
triggered by the application. The fire alarm is cancelled when the safety
position is left again.
Reset behavior
During a reset, the parameterized damper type and the end position switch
assignment are checked. If the settings are valid, the current damper position
is determined and the damper is moved to normal position.
Disorder treatment
Incorrect input telegrams (see LonMark™ specifications) are ignored.
