The NEW CAPO(Computer Aided Power Optimization) system controls engine and pump mutual power
at an optimum and less fuel consuming state for the selected work by mode selection, auto-
deceleration, power boost function, etc. It monitors machine conditions, for instance, engine speed,
coolant temperature, hydraulic oil temperature, and hydraulic oil pressure, etc.
It consists for a CPU controller, a cluster, an electronic control module (ECM), an EPPR valve, and other
components. The CPU controller and the cluster protect themselves from over-current and high voltage
input, and diagnose malfunctions caused by short or open circuit in electric system, and display error
codes on the cluster.

3. USER MODE SELECTION SYSTEM

Through 2 memory sets of MI and MII, an operator can change the engine and pump power and
memorize it for his preference.

Mode

Operation

U

High idle rpm, auto decel rpm
EPPR pressure can be modulated and memorized separately

HOW TO MODULATE THE MEMORY SET

Each memory mode has a initial set which are
mid-range of max engine speed, auto decel rpm,
and EPPR valve input current. When you select
"U", cluster LCD displays.

To change the engine high idle speed, press the
USER mode switch and SELECT switch at the
same time and then ACCEL blinks at 0.5 seconds
interval.

- By pressing or switch, will increase or

decrease.

To change DECEL rpm, press the USER mode
switch and SELECT switch once more and then
DECEL blinks at 0.5 seconds interval.

- By pressing or switch, will increase or

decrease.

To change EPPR current, press the USER mode
switch and SELECT switch one more and then
EPPR blinks at 0.5 seconds interval.

- By pressing or switch, will increase or

decrease.
