Simple to use !
The RTU is engineered with ease of operations in mind. All functions on the control
module are self explanatory. The LED display which shows the desired RPM setting is
easily visible both day and night.
How to operate :
When the RTU is on, the display will show 'IDLE' to indicate that the engine is at idle.
There are 4 pushbuttons on the control module :
1) The "Increase" and "Decrease" switches allow easy selection of desired RPM from
IDLE to maximum governed speed. Depress "Increase" to ramp the engine RPM up,
and depress "Decrease" to ramp the engine RPM down. The RPM will ramp up or
down at 50 RPM increment when pressed momentarily. When the pushbutton is held
down for more than 2 seconds, the RTU will ramp up or down in 100 RPM increments.
Release the pushbutton when desired RPM is reached.
2) The "IDLE" switch will bring engine to idle immediately after operations.
3) The "PRESET" switch ramps engine to the preset RPM quickly and conveniently
with the momentary touch of a single button.
(After the "PRESET" switch is used, the "Increase" and "Decrease" switches can still
be used to change the selected RPM easily.)
How do I change the preset RPM ?
a) Make sure the engine is at idle before proceeding. If the RTU does not display IDLE
in the display window, press the "IDLE" switch.
b) Press the "PRESET" switch with your left thumb and hold it in until the display
begins to flash. With your right hand press the "Increase" or "Decrease" switch to
change the flashing display until it reads the desired RPM.
c) When the desired RPM is obtained, release the "PRESET" switch and the RPM
shown in the window has become the new preset RPM and will be stored in the RTU's
memory.
