The timers tOpenPulse and tClosePulse are the length of the execute output pulses to be
sent to the primary equipment. Note that the output pulses for open and close command
can have different pulse lengths. The pulses can also be set to be adaptive with the
configuration parameter AdaptivePulse. Figure
126 shows the principle of the execute
output pulse. The AdaptivePulse parameter will have affect on both execute output pulses.
