1. Press and hold the SET key until the display shows a unit of measurement such as kPa,
psi, ect.
2. Then using the UP and Down keys navigate to the correct unit which is InHg for inches
of mercury.
3. Now return to the main display by pressing the SET key. This should bring you to a
screen with a low number on it for the current/live reading.
4. Press the SET key again and the display should read P_1 toggling to a number and then
back again.
5. Using the Arrow Keys adjust the number to P_1 setting on prints which would be the
ON trigger point of the vacuum switch.
6. Press the SET key again to go to P_2 and set to P_2 settings on prints which would be
the OFF trigger point of the vacuum switch. And press the SET key again.
7. Displayed will be P_3 which we leave set at its default. Press the SET key again so the
display reads P_4 and again leave this set at its default.
8. Now press the SET key until you are back to the main page which should have a low
number reading on it such as 0.0 to 0.4.
9. The Out 1 indicator should not be illuminated at this point and you are ready for
production.
System vacuum switch settings – P_1 = 18; P_2 = 15
Secondary vacuum switch settings – P_1 = 15; P_2 = 12
By setting these switches up in this manner the Vacuum switch will provide an output when we get
to 17.0 InHg and it will not loose its signal unless we drop below 15.0 InHg.
