If mode is MODE PSI, target (DISCHARGE–––PSI) strobes.
(See paragraph 4.1.2, Buttons/Targets (Drag-N-Drop Navigation), page 20,
for navigation descriptions/information.)
If mode is MODE RPM, target (ENGINE SPEED–––– RPM) strobes.
NOTE
No matter which governor mode is selected the (ENGINE SPEED–––– RPM) is always
either the primary target (which strobes) or the alternate target (which does NOT strobe
yet actives the preset buttons set point).
C. Release button (lift finger off touchscreen).
NOTE
If the operator only touches and releases the button; a confirmation popup window
appears (Figure 120). Touch the YES button to activate the preset or the NO button to
make no change.

The governors preset set point is activated.
6.3.4.2.1
Using PSI Mode
PSI Mode governor control of the apparatus differs from Auto Mode control of the apparatus, in
that, in PSI Mode the pumps discharge pressure (sensed at the PRESSURE port located in the
discharge side of the pump body) is being controlled to maintain a desired/selected set point.
Whereas, in Auto Mode the pump is controlled to maintain each individual discharges pressure
(sensed at the hose-side of each discharge valve). PSI Mode would be used anytime traditional
governor operations are desired/required (typically during annual NFPA required pump testing)
or if SAM Auto Mode fails or does NOT provide the desired control of the pump.
To select the desired/required PSI, simply use a preset (see the paragraph above if the applica-
ble preset exists). Otherwise, use the increase and/or decrease arrowhead on the PSI set point
icon group (see Figure 32, page 30) to select the desired/required SET PRESSURE, indicated in
the DISCHARGE PSI area of the Pump Controller home screen. To use PSI Mode, perform the fol-
lowing.
A.
Exit SAM Auto Mode as follows.
Touch MANUAL MODE button ( , see Mode Control on Figure 20, page 23).
If Pump Controller displays MODE RPM (see Figure 39, page 33), touch
MODE RPM arrowhead (directly above ENGINE SPEED icon group).
B. On Pump Controller PSI Mode screen, touch
+
or—arrowhead to digitally display
desired/required pressure under SET PRESSURE; or move analog pointer in ana-
log gauge portion of discharge PSI components (see Figure 34, page 31) to indi-
cate desired/required pressure.
