Function Description
Scheduler program Lighting can be switched on/off at specific times using a scheduler program.
Furthermore, automatic control can be activated or deactivated via scheduler program.
Another priority may need to be commanded depending on purpose. If, e.g., automatic
control should be activated at noon, manual operation must be overridden by allowing
the scheduler program to act on the priority for manual operation. If lighting is to be
switched off at night without allowing for manual operation, a higher priority must be
commanded.
Manual operation at high priority (room,
central)
Manual operation at high priority allows for influencing lighting blinds and overriding
low-priority functions. For example, this function allows for ensuring that neither
motion detectors nor scheduler programs can switch on/off lighting at the wrong time
during a lecture/presentation.
Maintenance, central For maintenance or cleaning, lighting is switched on/off at high priority enabling staff
to carry out all required work without risk of injury or being interrupted.
Protection, central Lighting can be switched on in the event of a fire alarm to light escape routes or
support emergency crew access.
A very simple control contains just one or two functions, A complex plant may
use many or all available functions. In addition, the response of individual
functions may require parameterization depending on the requirements. The
following figure shows an example of a plant including all functions.
