Error hold-off time
The ERROR HOLD-OFF TIME specifies the minimum time an error must be continuously
present in order to be indicated Total operation time.
Event
An instance report, characterized by its event number, of a change or a defined sequence of

Fast Fade Time can be set to zero or to any value in the range "Min Fast Fade Time".
Function test
Test to check the integrity of the circuit and the correct operation of a lamp, a changeover
device and the self-contained battery.
Hold time
The hold timer is only implemented for movement based sensors.
Hysteresis
Define a hysteresis band to direct impact on how sensitive the input device responds to
changes of illuminance level and therefore event generation.
Input device
Control device that is connected to the DALI bus and sends commands using a multi-master
transmitter in order to distribute information about user actions and/or sensor values.
Instance
Analogue or binary signal processing unit of an input device
