8.2.3 MDC Neutral Start Switch (NSS)
Adjustments
The neutral start switch (NSS) provides a means to
prevent the system prime mover from starting while
the pump control handle and control input shaft are in
a position which would command the pump to go “in-
stroke” in either the “forward” or “reverse” direction.
When the control input shaft is in its “neutral” position,
the inner end of the switch pin moves into a slot on the
eccentric cam attached to the control shaft. This
allows the spring loaded NSS to close, completing
the electrical starting circuit for the prime mover.
When the control input shaft is NOT in its “neutral”
position, the eccentric cam moves the switch pin out
of the slot. This forces the NSS to open, breaking the
electrical starting circuit for the prime mover.
