Figure 348: 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.
If the controlled primary device reaches the final position before the
execution pulse time has elapsed, and AdaptivePulse is not true, the
function waits for the end of the execution pulse before telling the
activating function that the command is completed.
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 close 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 when a primary device is open and an open command is executed is
shown in Figure 349.
