Control
The execute output pulses are reset when:
• the new expected final position is reached and the configuration parameter
set to true
• the timer
• an error occurs due to the switch does not start moving, that is,
There is one exception from the first item above. If the primary device is in open position and an
open command is executed or if the primary device is in closed position and a close command is
executed. In these cases, with the additional condition that the configuration parameter
AdaptivePulse is true, the execute output pulse is always activated and resets when tStartMove
has elapsed. If the configuration parameter
remains active until the pulse duration timer has elapsed.
An example of when a primary device is open and an open command is executed is shown in
