System vacuum switch settings –
P_1
= -18.0
Secondary vacuum switch settings –
P_1
= -15.0
By setting these switches up in this manner the system vacuum switch will provide an output when
we get to
18.0
InHg and it will not loose its signal unless we drop below
15.0
InHg. The secondary
vacuum switch set points will be
15.0
&
12.0
respectively.
These switches are sent with a
PSI
label affixed to the upper right corner of the display (The ZSE
model can sense both vacuum & pressure). There are extra labels that are shipped with each
switch.
Be sure to remove the
PSI
label and replace it with the
in/Hg
when this
procedure is completed.
