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
