BEFORE DRIVING
Description of the drive monitor type IQAN
The drive monitor’s purpose is to efficiently control the reach stacker’s hydraulic system and drive line by utilising both
analog and digital information from various sensors.
For example, prevent lowering, hoisting and extension in an overload situation. Prevent gear change from forward (F) to
reverse (R) as long as the machine is not stationary. Prevent the parking brake from being activated at too high speed.
Increase engine RPM when hoisting. Prevent full flow from the hydraulic pump at low engine RPM. Limit engine RPM
in case of high engine or transmission temperature.
The following options are also offered - regenerative fast hoist, automatic transmission, and joystick steering with
proportionaly limited steering movement at higher speeds.
The monitor informs and warns the driver via a display, if any value happens to be abnormal eg. overload, abnormal
pressure, or temperature.
The monitor can also be used for fault finding.
The monitor computes the following information:
- Position of the regulator motor on the fuel injection pump
- Position of the accelerator pedal
- Position of the joystick for boom hoist, lower, extend and retract
- Pressure in hoist cylinders
- Length and angle of the boom
- The engine, transmission and brake accumulator’s pressure
- Temperature of the engine and transmission
- Fuel level
- Position of gearshift lever and decluch gear function
- Parking brake switch
- Position of twist locks, open or locked
- RPM of engine and drive train
- Steering wheel’s angle and orbitrol pressure. Obs. joystick steering option
The monitor controls the following functions:
- Fuel pump regulator motor (engine RPM)
- The hydraulic valve for hoist and boom lower, extend and boom retract
- The transmission’s valves for F&R, 1st, 2nd, 3rd and 4th gears
- Opening and closing of the hose burst valves on the hoist cylinders
- Parking brake valve
- Fast hoist valves on the lift and extention cylinders, optional
- Steering system when joystick type steering fitted, optional
- Automatic transmission, optional
The following information can be obtained by utilising the display’s various keys
Description of the keys
Step keys (1) up, (2) forward, (3) down, and (4)
back, pages through the menues.
Menu/enter key (5), change menues/endorse fault
information.
Alternative keys (6,7,8 and 9)
After starting turning on the ignition switch, this
picture will be shown for approx. 1 second and will
then be followed by the logo which will be visible
for approx 2 to 3 seconds.
