• 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 breaker 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 to 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 207 .
