The pulse width of the KY pulse on a PM800 is dependant upon the firmware installed.
Prior to fw10.82 the KY pulse was a transition change pulse. With each triggering event the pulse would simply change state.
Figure 1 gives a graphical representation of how a transitional pulse would appear.
FW 10.82 and above gives the user the option of choosing to set the KY pulse to transition or pulse.
If the user chooses to set the KY pulse to pulse they can also define the pulse width as 10, 25, 50, 100, 150, 300, 500, or 1000 ms.
Figure 2 gives a graphical representation of how a user defined pulse width would appear.
Where t = user defined 10, 25, 50, 100, 150, 300, 500, or 1000 ms.
