Pressure Governor Flashcards
When in the pressure mode, discharge is monitored and PSI changes are limited to how many PSI?
30
The Fire Research PRO-S pressure will maintain a steady pump discharge pressure by controlling
the _____or maintain a selected engine RPM.
Engine Speed
While in the Pressure Mode Constant ____ will be maintained.
Discharge Pressure
Which color is the “pre-set” button?
Green
What color is the idle button?
Red
When switching the water supply source from tank to hydrant flow through the pump can become
turbulent and the positive pressure from these sources may generate a sudden pressure surge. It is
recommended that the PRO-S be set in ___ mode before changing the water supply source.
RPM
On power up, the Governor will be in what mode?
Pressure
The minimum pump discharge PSI must be greater than what PSI?
15
When pressing the increase/decrease button momentary, increase/decrease how many PSI?
1
Press and hold the button for more than __seconds and the RPM setting will change by 50 RPM
twice and then by 100 RPM until the button is released?
2
When switching between RPM and Pressure, pressure and RPM is limited to what increase?
None
If the PSI drops below 45 but stays above 15 the PRO-S will go into a prime cycle and set at?
1,100 RPM
In order to pump over 300 psi, the Pressure Governor must be operated in what Mode.
RPM
No or Low Water Supply: If the discharge pressure drops below 45 PSI but stays above 15 PSI the
PRO-S will go into a prime cycle. It will set the engine to 1100 RPM. If the pressure does not rise
above 45 PSI in ___ seconds the PRO-S will set the engine at idle RPM.
7 Seconds
When setting Program Preset Value the SETTING display must show ___before changing the preset.
Idle
