Total 2 Units This parameter defines the units for the Totalizer 2
Count (D829).
Pulse Width A Totalizer mode relay is energized for a
programmed duration (P534) each time the
Totalizer Count (D828 or D829) is incremented.
P534 controls the pulse width (i.e. the pulse 'on'
time) and is between 10 ms and 2.5 s, changeable in
steps of 10 ms.
Parameter P534 also defines the pulse width for a
