Functional checks

see page 2 (MVV-TB)
The functional check is the only regular maintenance measure required for maintenance-free fire dampers. The damper
blade has to be moved from the OPEN position into the CLOSED position, and then back into the OPEN position.
This task is performed by the motor modules in Wildeboer-Net.
The prerequisite for a remote-controlled functional check is that the motorised fire damper has been checked reliably
to make sure that the CLOSED and OPEN positions are reached and this has been documented. The limit switches
required for this purpose are included in the motors on the fire dampers. The running performance of the fire damper
is recorded. The results of the functional check are stored reliably and permanently on the field modules, and in the
Wildeboer-Net software after downloading.
The functional check can be carried out for all fire dampers simultaneously, but also for selected groups or individual
fire dampers. This only ever takes a few minutes, regardless of the number of dampers. As a result, even on large
systems the influence of the checks on operation are reduced to a minimum. This way, functional checks can be
carried out problem-free at shorter intervals, thus increasing the reliability and availability of the system considerably.
Functional checks can be scheduled easily using a timetable. They are started automatically or manually at a defined
deadline. For scheduled automatically started functional checks the fan enabling function
(

see page 9),
using an optional
I/O module, should definitely be used to shut off the fan. Scheduled functional checks are monitored to make sure
that they are carried out. Checks which are carried out with a delay, or not carried out at all, are marked accordingly
in the logs.
Functional checks can also be started manually at any time. A manual shut-off of the fan can be parametrised for
manually started functional checks. A functional check can be started locally using a motor module, regardless of the
status of commissioning of the overall system. This way, it is possible to locally check that the fire damper is properly
connected to the motor module and also check that the fire damper is fully functional, directly after installation. This
makes it much easier to carry out commissioning of the overall system at a later time.
To assess the results of the functional check using the Wildeboer-Net software, the data has to be read out by the
decentralised field modules. During the download, parametrised sequence controls, calendar controls and release
groups are deactivated. On larger systems the download can take a few minutes. A table view which contains all
dampers, and a graphic trend analysis (
⇒
see page 15
) for individual dampers are available for analysis purposes. This
way, any required maintenance measures can be detected and arranged in good time. An export function to Excel is
available for documentation purposes.
That way, the building code requirements in MVV-TB for regular checking of the function of the fire dampers can be
met from a central point.
