In Pressure Mode, press either button momentarily to change the pressure setting by 1 PSI. Press and hold the button for more than 2 seconds and the pressure setting will change by 5 PSI twice and then by 10 PSI until the button is released. In RPM Mode, press either button momentarily to change the RPM setting by 10 RPM. Press and hold the button for more than 2 seconds and the RPM setting will change by 50 RPM twice and then by 100 RPM until the button is released.
pro s change modes hold mode button how long
3 seconds
no or low supply water
there are situations during pump operations when there may be no or low water supply. This can be due to an empty water tank, a problem with the supply line, or when switching the water supply source.
In Pressure Mode the PRO-S will increase the engine RPM and attempt to maintain the selected pressure setting. 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 7 seconds the PRO-S will set the engine at idle RPM. The PRO-S will continue repeating the prime cycle as long as the discharge pressure is between 15 and 45 PSI. If the discharge pressure drops below 15 PSI, the engine RPM will go to idle and the SETTING display will show the selected setting. When the discharge pressure rises above 15 PSI the PRO-S will resume control at the previous selected setting.

The auxiliary front wheel lock feature uses air brake system pressure to keep the front brakes applied. It is used to augment the rear spring parking brakes in the event the rear parking brakes cannot hold the apparatus on a steep incline. As such, if there is an air leak in the air brake system, the auxiliary front wheel locks may fail. Therefore, if the auxiliary parking brake is to be used, it should be used only with the engine running.

Jake brake settings:
Low – Activates two cylinders for medium engine retarding.
Medium – Activates four cylinders for moderate engine retarding.
High – Activates six cylinders for maximum engine retarding.

if low voltage (less than 11.9V) continues for __ minute, shedding electrical loads begin
1 minute
A shed system (load) will not be recognized for 5 minutes or until the unshed voltage setting is maintained for 1 minute. The fast idle system will be maintained for a minimum of 10 minutes and until a voltage reading of 13.0 is achieved, even if any system shedding did not occur.
