Manual fan shut-off for functional checks
A parametrisable manual fan shut-off for functional checks is integrated into Wildeboer-Net. The application is used
when it is necessary to shut off the fan before and after carrying out a functional check for system reasons. The use of
an I/O module is required for this purpose. The fan is shut off via an output of the I/O module as soon as a functional
check is to be performed for one or more of the fire dampers assigned to the fan. A functional check cannot be started
manually until feedback has been signalled via an input of the I/O module to confirm that the fan has been shut off.
The mechanism is valid for non-scheduled and scheduled manually started functional checks. The fan has to be shut
off and switched on, and the functional checks have to be started manually using the Wildeboer-Net software. The
mechanism is not effective for functional checks which are started locally using the motor modules directly.
The required control inputs and outputs are simply integrated into the group definition. All the required connections
and settings are set automatically by the Wildeboer-Net software. A separate fan shut-off is defined for each group.
