Figure 122: Execute output pulse
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 123 .
