Selects whether or not a 30-ms deactivation delay is added to
account for alternating current.
Scanning cycle
All digital inputs are scanned in a 5 ms cycle, meaning that the state of an input is updated every 0…5
milliseconds. When an input is used internally in the device (either in group change or logic), it takes
additional 0…5 milliseconds to operate. Theoretically, therefore, it takes 0…10 milliseconds to change
the group when a digital input is used for group control or a similar function. In practice, however, the
delay is between 2…8 milliseconds about 95 % of the time. When a digital input is connected directly
to a digital output (T1…Tx), it takes an additional 5 ms round. Therefore, when a digital input controls a
digital output internally, it takes 0…15 milliseconds in theory and 2…13 milliseconds in practice.
