Figure 181: The timers tStartMove and tIntermediate
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
182 shows the
principle of the execute output pulse. The AdaptivePulse parameter will have effect
on both execute output pulses.

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:
