If the pulse is set to be adaptive, it is not possible for the pulse to exceed tOpenPulse or
tClosePulse.
The execute output pulses are reset when:
• the new expected final position is reached and the configuration parameter
AdaptivePulse is set to true
• the timer tOpenPulse or tClosePulse has elapsed
• an error occurs due to the switch does not start moving, that is, tStartMove has
elapsed.
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 AdaptivePulse is set to false the execution output remains active until the
pulse duration timer has elapsed.
If the start position indicates bad state (OPENPOS=1 and CLOSEPOS
=1) when a command is executed the execute output pulse resets only
when timer tOpenPulse or tClosePulse has elapsed.
An example of when a primary device is open and an open command is executed is
shown in figure 340 .
