4 Commands with Priority Mode 3

In this mode, any command applied at the device input is transmitted for 20 ms or for the time set in time slot.
The next command is then transmitted or the same command is transmitted again (only if there is no other
command active at the inputs) depending on the priority. The command output can optionally be extended at
the receiver output in steps of 5 ms to maximum 2000 ms. To avoid that the output relays drops a prolonga-
tion time ≥ 100 ms must be set. This extension makes it possible to transmit commands from all input combi-
nations depending on priority.

Command Duration for Alternate Multi-Purpose Operation

2.8.5
The command duration for the integrated SWT 3000 is automatically adjusted to a default value of 1000 ms.
Inputs can be activated for a longer time but the transmission of the signal is limited to 1000 ms. The trans-
mission of the commands is switched off due to the limited command duration even though the command is
active at the input of the device.
