JOYSTICK FUNCTIONS
: (Figure 18)
To operate a function the following series of events must work.
1. The Joystick Controller is moved in the correct direction the required distance, During its movement
an electrical signal is sent to the electric Controller in the proper Valve Section of the Control Valve.
2. The Electric Controller sends an electrical signal, which causes the Proportional Control Valves to
actuate the proper amount based on the signal from the Controller. EXAMPLE: Valves 1 & 3 allow
Pilot Pressure Oil to flow to the corresponding end of the Spool, Thus causing it to move. Valves 2
& 4 allow the Oil from the opposite end of the Spool to return to the Tank. (NOTE: Lift, Swing and
Dipper functions are Proportional, Door and Tilt functions are “ON” or “Off” Only, See later section
for explanation of Proportional).
3. The Spool position Transducer sends an electrical signal to the Electronic Controller which indicates
the position of the Spool.
4. The Electronic Controller will continue to adjust the Valves (1 - 4) in order to maintain an equilibrium
between the Joystick signal and the feedback signal.
5. Reaction time from the time the Joystick is moved until the Spool moves is approximately 300
milliseconds.

FIGURE 18
The Joystick is P/N 02981374. The Plug in connections are marked with numbers on the plastic plug.
The wires are solid color or a color with a stripe. The Plugs should not fit but one way and that is by
matching the codes on the plugs.
