Electrical System
The quantity of oil discharged by the pump and the engine speed are determined by the mode selected by
the operator. The pump output in each mode is determined by the mode selection and is listed in the
following table
OPERATION
1.
Power Mode
This mode should be selected for high
speed work. In this mode the engine
output is most efficiently utilized due to the
discharged oil volume being controlled
based on the equivalent horsepower curve
at various loaded pressures. The e-EPOS
controller compares the target engine
speed with the actual engine speed and
controls the signal to the E.P.P.R. (Electric
Proportional Pressure Reducing) valve
which in turn varies the pump output
quantity.
If the load increases, the engine speed will
fall below the rated speed. When this
occurs, the controller senses this decrease
and immediately reduces the pump
discharge volume to maintain the engine
speed at the rated level.
On the other hand, if the load is decreased the controller increases the discharge volume of the pump
to maintain the engine speed at the rated level.
By repeating these control operations, the engine speed is maintained at the rated speed so that
maximum power can be generated.
In Power Mode, the controller receives engine speed signals from the engine speed sensor and the
throttle position sensor (sensor is built into engine control motor) and converts it to an operating
signal current and is then transferred to the pump’s E.P.P.R valve. At this time the E.P.P.R. valve
converts the electric signal to the corresponding control pressure and sends it to the two pumps,
adjusting the pump discharge volume to the desired level.
