1.4 OPERATION

The Genie V-2470 & V-2470RT are controlled from the platform control station. This control station consists of a DRIVE Forward/Reverse joystick, a DRIVE SPEED High/Low toggle switch (Genie V-2470 only), STEER Left/Right toggle switch, an ELEVATE Up/Down toggle switch, and on the Genie V-2470RT a START/CHOKE toggle switch.

To operate the machine, the operator turns the key switch to the PLATFORM position and pulls up on the red POWER On/Off button located on the ground control station. The operator may now enter the platform and pull up on the platform control station POWER On/Off button. The Genie V-2470 is now operational. Follow the above instructions for the Genie V-2470RT and add these simple steps: Select the desired fuel (on the ground control station), then actuate the Start/Choke toggle switch to the proper position. The Genie V-2470RT should now be operational.

The machine may then be driven to the work location, and the platform elevated to the task. The chassis may be repositioned while the platform is elevated by driving the machine to the desired position.

IMPORTANT: NEVER ELEVATE THE PLATFORM OR DRIVE THE MACHINE WITH THE PLATFORM ELEVATED UNLESS THE MACHINE IS ON A FIRM LEVEL SURFACE.

The ground control station provides controls for the elevate functions, and on the Genie V-2470RT, controls for START/CHOKE and FUEL Select.

In the event of a control circuit or hydraulic system power loss, the machine incorporates a manual lowering valve, located on the elevate cylinder.

At the end of each day the key switch should be turned off. The integral battery charger on the Genie V-2470 should be connected to the appropriate AC power source, and the fuel levels on the Genie V-2470RT should be checked.

3.6 GENIE V-2470 THEORY OF OPERATION

Energy Source

The Genie V-2470 vertical lift is powered by eight (8) 6 volt batteries connected in a series/parallel configuration to provide 24 volt DC power. Each battery is rated at 250 amp. hr. at a 20 hour rate.

Charging System

A 24 volt, 35 amp. line compensating battery charger is used to recharge the battery pack after each day's use. The charger utilizes an electronic current limiting system which automatically controls the charge rate, depending on battery condition. The charge rate tapers off as the batteries approach full charge.

Hydraulic System

The hydraulic system consists of ELEVATE Up/Down, STEER Left/Right and DRIVE Forward/Reverse. To power these functions the hydraulic system uses a hydraulic power unit incorporating a 24 volt electric motor and a two stage gear pump which delivers a total displacement of 6.5 gpm (24.6 liters per minute). A pump unloader valve is incorporated to regulate one stage of the pump. When pilot pressure to the unloader valve reaches a set pressure it will open, creating a flow path to the tank for the regulated pump stage. When the motor is supplied with 24 volts, it turns the pump to supply hydraulic oil to the hydraulic system directional control valves located on the chassis mounted hydraulic control manifold. When actuated, the directional control valves direct hydraulic oil to the hydraulic system actuators (elevate cylinder, steering cylinder, wheel drive motors and wheel drive brakes). A 3100 psi (21373 kPa) relief valve (located on the hydraulic control manifold) is used to prevent the hydraulic system from being over pressurized. To ensure that the steering system is always supplied with hydraulic oil, the hydraulic control manifold incorporates a priority flow divider. The priority flow divider ensures that the steering systems hydraulic oil requirement is met prior to supplying hydraulic oil to the drive system. Located on the hydraulic control manifold is a drive proportional control valve. The drive proportional control valve is used to control the speed of the DRIVE Forward/Reverse functions by regulating the flow of hydraulic oil in direct relation to the valves input voltage.

Page 60

Section 3.6 V-2470 Theory of Operation Continued

The ELEVATE Up/Down functions utilize one lifting cylinder. The ELEVATE Up function is accomplished by actuating the elevate up directional control valve (located on the hydraulic control manifold) thereby directing hydraulic oil to the elevate cylinder. The hydraulic control manifold incorporates a 3000 psi (20684 kPa) relief valve which prevents the elevate system from experiencing over pressurization. Another manifold, attached to the barrel end port of the cylinder, incorporates a down directional control valve, a manual lowering valve, flow control cartridge valve, and a check valve. The ELEVATE Down function is accomplished by actuating the down directional control valve, this allows a flow path for hydraulic oil to exit the cylinder causing it to retract. The manual lowering valve accomplishes the same tasks as the down directional control valve in the event of an electrical system failure. A pressure compensated flow control cartridge valve restricts the rate that the cylinder retracts by regulating the hydraulic oil exiting the cvlinder. The check valve is used to maintain cylinder pressure and prevent free descent in the event of a hydraulic line failure.

The STEER Left/Right functions utilize one dual acting cylinder. The steering functions are accomplished by actuating the steering left and right, 3-position, 4-way, directional control valve (located on the hydraulic control cylinder), thereby directing hydraulic oil to the steering cylinder. Located on the hydraulic control manifold is a 1100 psi (7584 kPa) relief valve which prevents the steering system from being over pressurized.

The DRIVE Forward/Reverse functions uses two 7.1 cubic in. (116 cm³) rotary drive motors, with 4.1:1 planetary torque hubs, and spring applied, hydraulically released brakes. The functions are accomplished by actuating the drive forward or reverse directional control valve (located on the hydraulic control manifold), thereby directing hydraulic oil to the drive brake shuttle valve (located in the hydraulic control manifold) and to the wheel drive motors. The shuttle valve directs hydraulic oil to the drive brakes releasing the brakes. The DRIVE functions use two counter balance valves (located on the hydraulic control manifold) to prevent the machine from exceeding the maximum drive speed and to aid in hydrodynamic braking. Located on the hydraulic control manifold is a series/parallel directional control valve. This valve gives the machine the capability of operating the drive functions in a low speed, high torque mode or in a high speed, low torque mode. When operating in Low range the valve creates a parallel path for hydraulic oil flowing to the wheel drive motors. This causes a low speed, high torque drive mode. When operating in High range the valve creates a series path for hydraulic oil flowing to the wheel drive motors. This causes a high speed, low torque drive mode.

Section 3.6 Genie V-2470 Theory of Operation Continued

Electrical System

The electrical system consists of ELEVATE Up/Down, STEER Left/Right, and DRIVE Forward/Reverse. The electrical system uses stored electrical energy to power and control all machine functions. The electrical system can be divided into two categories the control circuit and the power circuit.

The control circuit incorporates the components and circuitry required to turn the machine on and off, or control other electrical devices. Components include the key switch, toggle switches, limit switches, POWER On/Off buttons, low voltage interrupt system (optional), diodes and solenoids. Since the control circuit typically conducts very low current, small diameter wire and multi-wire (19 conductor, 18 AWG) control cables are used, to connect the control circuit components.

The power circuit incorporates the components which convert stored electrical energy into a mechanical force to provide movement. Components include the batteries, electric motors and contacts. Since the power circuit must be able to conduct full operating current, heavy #2 and #4 welding cable is used to connect the power circuit components.

Before any machine functions can be operated, the key switch (located on the ground control station) must be turned to the appropriate PLATFORM or GROUND position and the POWER On/Off buttons must be pulled up. Turning the key switch to either position (PLATFORM or GROUND) and pulling up the POWER buttons completes a 24 volt circuit from the batteries to the printed circuit board located at the ground control station. At the printed circuit board current is used to energize a 24 volt control circuit master relay (located in the ground control station). The 24 volt control circuit master relay energizes a set of 24 volt contacts, which, when closed, completes a circuit supplying 24 volts from the batteries to the selected platform or ground control station actuators.

The ELEVATE Up/Down functions can be operated from either the platform control station or the ground control station by actuating the proper function control toggle switch. When the toggle switch is actuated a circuit is completed from the toggle switch to the 24 volt motor start relay and to the elevate up 24 volt directional control valve solenoid. The ELEVATE Down function is not a powered function and does not supply 24 volts to the motor start relay. When supplied with 24 volts, the motor start relay energizes a set of 24 volt contacts which when closed completes a circuit supplying 24 volts to the hydraulic power

Page 62

Section 3.6 Genie V-2470 Theory of Operation Continued

unit. When energized, the 24 volt directional control valve solenoids activate their respective control valves. Whenever the above-mentioned actions are accomplished, the appropriate elevate function will operate.

The STEER Left/Right functions are operated from the platform control station by actuating the STEER toggle switch to the desired position. When actuated the toggle switch completes a circuit to the 24 volt motor start relay and to the 24 volt steer left or right directional control valve solenoid. When supplied with 24 volts the motor start relay energizes a set of 24 volt contacts which, when closed, completes a circuit supplying 24 volts to the hydraulic power unit. When energized, the 24 volt directional control valve solenoids activate their respective control valve. Whenever the above mentioned actions are accomplished, the appropriate steer function will operate.

The DRIVE Forward/Reverse functions are operated from the platform control station. The direction of the DRIVE Forward/Reverse functions are accomplished by actuating the drive proportional control joystick in either the Forward or Reverse position. When actuated the joystick completes a circuit to the 24 volt motor start relay, the 24 volt forward or reverse directional control valve solenoid, and the drive proportional control valve solenoid. When supplied with 24 volts the motor start relay energizes a set of 24 volt contacts which, when closed, completes a circuit supplying 24 volts to the hydraulic power unit. When energized the 24 volt directional control valve solenoids actuate their respective control valves. The speed of the DRIVE Forward/Reverse functions is controlled by the variable current supplied to the drive proportional control valve from the drive proportional control joystick. Whenever the above-mentioned functions are accomplished, the appropriate drive function will operate.

Page 63

3.7 GENIE V-2470RT THEORY OF OPERATION

Energy Source

The Genie V-2470RT vertical lift is powered by a dual fuel 24 horsepower internal combustion engine.

Charging System

The internal combustion engine incorporates an integral flywheel mounted 12 volt-20 amp alternator and voltage regulator system.

Hydraulic System

The hydraulic system consists of ELEVATE Up/Down, STEER Left/Right and DRIVE Forward/Reverse. To power these functions the hydraulic system uses a three stage gear pump that delivers a total flow displacement of 17.5 gpm (66.2 liters per minute).

The first pump stage is used to supply the ELEVATE function with hydraulic oil, providing a total flow displacement of 2.5 gpm (9.5 liters per minute).

The last two stages are used to supply the STEER and DRIVE functions with hydraulic oil, providing a total flow displacement of 15 gpm (56.8 liters per minute). A pump unloader valve is incorporated to regulate one stage of the pump. When pilot pressure to the unloader valve reaches a set pressure it will open, creating a flow path to the tank for the regulated pump stage.

When the internal combustion engine is operating, it turns the pump to supply hydraulic oil to the hydraulic system directional control valves located on the chassis mounted hydraulic control manifold. When actuated, the directional control valves direct hydraulic oil to the hydraulic system actuators (elevate cylinder, steering cylinder, wheel drive motors, and wheel drive brakes). Two 3000 psi (20684 kPa) relief valves (located on the hydraulic control manifold) are used to prevent the hydraulic system from being over pressurized. To ensure that the steering system is always supplied with hydraulic oil, the hydraulic control manifold

Page 64

incorporates a priority flow divider. The priority flow divider ensures that the steering systems hydraulic oil requirement is met prior to supplying hydraulic oil to the elevate system. Located on the hydraulic control manifold is a drive proportional control valve. This valve is used to control the speed of the DRIVE Forward/Reverse functions by regulating the flow of hydraulic oil in direct relation to the valves input voltage.

The ELEVATE Up/Down functions utilize one lifting cylinder. The ELEVATE Up function is accomplished by actuating the elevate up directional control valve (located on the hydraulic control manifold) thereby directing hydraulic oil to the elevate cylinder. Another manifold, attached to the barrel end port of the cylinder, incorporates a down directional control valve, a manual lowering valve, flow control cartridge valve, and a check valve. The ELEVATE Down function is accomplished by actuating the down directional control valve, this allows a flow path for hydraulic oil to exit the cylinder causing it to retract. The manual lowering valve accomplishes the same tasks as the down directional control valve in the event of an electrical system failure. A pressure compensated flow control cartridge value restricts the rate that the cylinder retracts by regulating the hydraulic oil exiting the cylinder. The check valve is used to maintain cylinder pressure and prevent free descent in the event of a hydraulic line failure.

The DRIVE Forward/Reverse functions uses two 3.6 cubic in. (59 cm³) rotary drive motors, with 24.85:1 planetary torque hubs, and spring applied, hydraulically released brakes. The functions are accomplished by actuating the drive forward or reverse directional control valve (located on the hydraulic control manifold), thereby directing hydraulic oil to the drive brake shuttle valve (located in the hydraulic control manifold) and to the wheel drive motors. The shuttle valve directs hydraulic oil to the drive brakes releasing the brakes. The DRIVE functions use two counter balance valves (located on the hydraulic control manifold) to prevent the machine from exceeding the maximum drive speed and to aid in hydrodynamic braking.

Electrical System

The electrical system consists of ELEVATE Up/Down, STEER Left/Right, and DRIVE Forward/Reverse. The electrical system stored electrical energy to control all machine functions. The electrical system is divided into two categories: The control circuit and the power circuit.

The control circuit incorporates the components and circuitry required to turn the machine on and off, or control other electrical devices. Components include the key switch, toggle switches, limit switches, POWER On/Off buttons, low voltage interrupt system (optional), diodes and solenoids. Since the control circuit typically conducts very low current, small diameter (19 conductor, 18 AWG) wire and multi-wire control cables are used, to connect the control circuit components.

The power circuit incorporates the components which convert stored electrical energy into a mechanical force to provide movement. Components include the batteries, starter motor and contacts. Since the power circuit must be able to conduct full operating current, heavy #2 and #4 welding cable is used to connect the power circuit components.

Before any machine functions can be operated, the key switch (located on the ground control station) must be turned to the appropriate PLATFORM or GROUND position, the POWER On/Off buttons must be pulled up.

Turning the key switch to either position (PLATFORM or GROUND) and pulling up the POWER buttons completes a 12 volt circuit from the battery to the printed circuit board located at the ground control station. At the printed circuit board current is used to energize a 12 volt control circuit master relay (located in the ground control station). This relay energizes a set of 12 volt contacts which, when closed, completes a circuit supplying 12 volts from the battery to the selected platform or ground control station actuators. At this point the START/CHOKE toggle switch may be actuated.

The ELEVATE Up/Down functions can be operated from either the platform control station or the ground control station by actuating the ELEVATE toggle switch to the desired position. When the ELEVATE toggle switch is actuated a circuit is completed from the toggle switch to the 12 volt elevate up or down directional control valve solenoid. When energized, the 12 volt directional control valve solenoids actuate their respective control valves. Whenever the above-mentioned actions are accomplished, the appropriate elevate function will operate.

Page 66

Section 3.7 Genie V-2470RT Theory of Operation Continued

The STEER Left/Right functions are operated from the platform control station by actuating the STEER toggle switch to the desired position. When actuated, the STEER toggle switch completes a circuit to the 12 volt steer right or left directional control valve solenoid. When energized, the 12 volt directional control valve solenoids actuate their respective control valves. Whenever the above mentioned actions are accomplished, the appropriate steer function will operate.

The DRIVE Forward/Reverse functions are operated from the platform control station. The direction of the DRIVE Forward/Reverse function is accomplished by actuating the drive proportional control joystick in either the Forward or Reverse position. When actuated, the joystick completes a circuit to the 12 volt forward or reverse directional control valve solenoid and the drive proportional control valve solenoid. When energized, the 12 volt directional control valve solenoids actuate their respective control valves. The speed of the DRIVE Forward/Reverse functions is controlled by the variable current supplied to the drive proportional control valve from the drive proportional control joystick. Whenever the above-mentioned functions are accomplished, the appropriate drive function will operate.

Troubleshooting Introduction

The following section is designed to aid in the diagnosis of problems which may occur on a Genie Vertical Lift. A system of troubleshooting flow charts is used to diagnose problems ranging from defective solenoids to the need for pump replacement. To use this section, a technician should have the following basic hand tools and test equipment: a voltmeter, ohmmeter, pressure gauges, and flow meters.

Included in this section are twenty seven (27) troubleshooting flow charts which cover various machine defective conditions for both the Genie V-2470 & V-2470RT. These flow charts include several numbered tests, and test results (shaded boxes), which are used to direct the technician to the recommended machine repair. Bold framed boxes indicate that the flow chart continues on another page.

Before performing any machine tests the following safety precautions should be observed:

o Read and understand sections 3.6 and/or 3.7, Theory of Operation.
o Read and follow all the safety instructions listed in section 2.1, Mandatory Precautions, and as indicated by decals on the Genie Vertical Lift.
o When troubleshooting, make certain the machine is resting on a firm, smooth, level surface.
When testing drive system defective conditions, make certain the machine is secured from rolling by chocking the front tires and by jacking the machine drive assembly off the ground before conducting any tests.
Two persons will be needed to safely conduct some drive system defective condition tests.

This Troubleshooting section deals primarily with malfunctions or defective components. Therefore, make certain all correct operating procedures are performed prior to conducting any of the recommended tests.

It should be noted that various degrees of a particular function loss may occur. For example: "ELEVATE Up function inoperative". This should mean "Elevate cylinder will not extend with the same speed or power of a properly functioning machine."

Page 80

Section 4.5 Troubleshooting Continued

NOTE : Proper diagnosis of a problem can only be done with batteries which are fully charged (discharged batteries will result in sluggish operation) and, on the Genie V-2470RT, have the engine running (if possible).

Throughout this Troubleshooting section, references are made to terminal numbers. For the exact location of these terminal points, refer to the electrical schematic and accompanying legend in section 5.2, Electrical Schematics & Diagrams.

Pages 4.12 (V-2470) and 4.33 (V-2470RT) contain a list of problems which may occur due to component malfunctions. Refer to the flow chart which most accurately describes your problem. In multiple-problem cases, solve one problem at a time beginning with the lowest number.

If you have any questions concerning this Troubleshooting section, you will be best served by referring to the defective condition flow chart number and machine test number when calling the Genie Service department toll free 800-426-8089.
