Type I Pump Governor

Question 1

at what psi is the high idle feature disabled?

Answer 1

if there is >10psi at the pump transducer

Question 2

If discharge pressure drops below 30psi for any reason, what will happen

Answer 2

The engine speed will not increase and “intake” will flash

Question 3

when operating the “INC” switch, and operating above 90psi, what is the maximum amount of pressure increase that the computer will continuously allow?

Answer 3

it won’t allow anything greater than 80psi additional to be added until finger is taken off the increase button

Question 4

how does the governor maintain pump pressure?

Answer 4

by controlling engine RPM in response to a signal from the pressure transducer mounted to the pump

Question 5

If pressure above 30psi is not regained within 5 seconds, what will happen

Answer 5

Engine will go to idle and “losupply” will flash

Question 6

in general, what does “operator” mean anytime it flashes on the screen?

Answer 6

in general, it flashes anytime the governor can’t achieve a desired pressure

Question 7

RPM MODE

If pressure increases >50psi from last logged pressure, what pressure will the governor limit the increase

Answer 7

No more than a 50psi differential

Question 8

at what pressure will the governor begin to control pressure

Answer 8

once pump pressure exceeds 70psi

Question 9

If pressure increases above 30psi, what happens

Answer 9

“operator” will flash and pressure wont increase until “inc” is pressed
