All the parameters are programmable by means of the ZAPI console.

-

Complete diagnosis through console or MDI.

-

High temperature protection with current reduction.

-

Drivers real time diagnosis (electro-brake, general contactor and proportional valve.

-

Electrobrake and general contactor are controlled with a PWM.

-

Page 3

1.4 SAFETY & PROTECTION FEATURES - Reverse Battery Polarity.

Electrical Circuit diagrams must be followed in order to avoid damage to the power unit. A Main contactor, controlled by the logic unit, is necessary to protect the system against reverse battery polarity.

- Connection errors All inputs are protected against connections errors. Contactor drivers are suitable for loads up to 2 Amps, and are protected against overload.

- Thermal protection If the controller temperature exceeds 77°C, the maximum current will be reduced proportionaly to the thermal increase. The temperature can never exceed 90°C. - Low Battery charge When the battery charge is low, the maximum current is reduced.

- External Agents The chopper is protected against dust and spray of liquid to a degree of protection meeting IP64.

- Protection against accidental Start Up A precise sequence of operations is necessary before the machine starts. If these operations are not carried out correctly the machine stops. Driving requests must be made after closing the Key Switch.

- Protection against uncontrolled movements.

The Main Contactor will not close if: - The Power Unit is not operating correctly - The Logic Unit is not operating correctly - The Serial Tiller is not operating correctly 1.5 THERMAL CONSIDERATIONS - The heat generated by the power block must be dissipated. For this to be possible, the compartment must be ventilated and the heat sink materials ample.

- The heat sink material and system should be sized on the performance requirement of the machine. Abnormal ambient air temperatures should be considered. In situations where either ventilation is poor, or heat exchange is difficult, forced air ventilation should be used.

- The thermal energy dissipated by the power block module varies and is dependent on the current drawn and the duty cycle.

Page 4

1.6 COMBI SEM-1 CHOPPER DIAGNOSIS The microprocessor continually monitors the chopper and carries out diagnostic procedures on the main functions.

The diagnosis is made in 4 points: 1) Diagnosis on key switch closing that checks: watch-dog, Current Sensors, VMN point, contactor drivers, presence of a start requirement, and connection with the Serial Tiller ok.

2) Standby Diagnosis that checks: watch-dog, VMN Point, Contactor Drivers, Current Sensors.

3) Driving diagnosis that checks: Watchdog, VMN Point, Current, Contactor(s).

4) Continuos Diagnosis that checks: Chopper temperature, Battery Voltage.

1.7 MAIN CONTACTOR AND SAFETY BUTTON - Battery disconnection should be made according to the Diagram below.

- In order to avoid damage to the controller during the regenerative phase, the supply to the Key Switch must be cut off at the same time.

Wiring with cut off in series to positive supply.

- An internal protection is activated when the voltage on B12 connector is greater than 30% of battery voltage, or when the key switch is opened before the battery is opened.

Page 5

1.8 GENERAL INSTRUCTIONS AND PRECAUTIONS - Never combine SCR low frequency choppers with COMBI SEM-1 modules. The filter capacitors contained in the COMBI SEM-1 module would change the SCR chopper operation and subject it to excessive workload. If it is necessary to use two or more control units, the choppers should both be of the High Frequency Zapi family.

- Do not connect the chopper to a battery with a different nominal voltage to the value indicated on the chopper. A higher battery voltage may cause MOS failure. A lower voltage may prevent the logic operating.

- During battery recharge, the COMBI SEM-1 must be completely disconnected from the battery. Beside changing the charging current seen by the battery charger, the module can be damaged by higher than normal voltages supplied via the charger.

- The COMBI SEM-1 module should only be connected to a traction battery. Do not use converters outputs or power supplies. For special applications please contact the nearest Zapi Service Centre.

- In the first instance, start the machine with the drive wheels raised from the floor to ensure that any installation error do not compromise safety.

- After operation, even with the Key Switch open, the internal capacitors may remain charged for some time. For safe operation, we recommend that the battery is disconnected, and a short circuit is made between Battery Positive and Battery Negative power terminals of the chopper using a Resistor between 10W and 100W. Minimum 5 W. - The susceptibility and electromagnetic emmission levels are seriously influenced by installation conditions. Take particular care with the length of cables and wires, types of electrical connections, and braided/screened wires. Zapi declines any responsibility for incorrect or bad operation that can be attributed to the above circumstances. Above all, the manufacturer of the machine must ensure that the requirements of EN 50081-2 are met.

Page 6

2 INSTALLATION Install the chopper baseplate onto a flat metallic surface that is clean and unpainted.

Apply a very thin layer of thermo-conductive grease between the two surfaces to permit better heat dissipation.

Despite the protection provided against external agents, the continuous attack of corrosive elements and substances may cause oxidization of contacts, resulting in bad operation. Remember this point when deciding the installation position on the vehicle.

Fix the chopper using the special holes located on the baseplate (maximum screwing torque: 3 Nm for M5 and 4Nm for M8 screws).

Verify that the wiring of the cable terminals and connectors has been carried out correctly.

2.1 CONNECTION CABLES For the auxiliary circuits use cables bigger or equal to 0.5mm2 section.

For power connections to the motor (pump and traction rotor) and to the battery use cables of 16÷25 mm2 section. The cables from chopper to battery should be run side by side and be as short as possible.

2.2 CONTACTORS A Main Contactor, designed for Continuous Operation should be installed. This contactor should be fitted with a coil corresponding to the battery voltage. The current absorbed by the coil must not be greater than 2A. Suppression for this contactor coil is inside the chopper logic. Do not use any additional external suppression.

2.3 FUSES - Use a 10A fuse for protection of the auxiliary circuits.

- The power fuse is alrady installed on the chopper by Zapi. For special applications or requirements this value can be reduced.

4 REGULATION

4.1 ZAPI PROGRAMMING HANDLY CONSOLE In Combi Sem-1 controller is possible to program several functions through the console.

In this way is possible to modify the performances of the truck following the customer needings.

The console can remain connected to the controller while running and the parameters can be changed in real time. In this case it is important to go in stand by condition before switch off the controller in order to give the possibility to store the new values in the Eeprom.

This section describes the ZAPI console functions.

Six buttons provide the capability of changing or reading the parameter of the Combi: 1

Roll-Up

push to scroll up the submenu and to select a parameter;

2

Roll-Down

push to scroll down the submenu and to select a parameter;

3

Enter

push to have access to the selected submenu or to confirm a changement;

4

Out

push to exit the selected menu or to refuse a changement;

5

Set-Up

push to increase a parameter;

6

Set-Down

push to decrease a parameter;

Note: After a modify, memoriz the new value pushing the "4" (Out) button and the "3" (Enter) button. Double pushing of the "4" (Out) button doesn't save the value.

Numbers inside the triangles in the following map correspond to the same number on the console keyboard buttons shown in the figure below. The orientation of the triangle indicates the way to the next function.

1. OVERVIEW ELECTRONIC POWER STEERING FOR INDUSTRIAL BATTERY TRUCKS FLY BY WIRE is the name of a series of controllers for electronic power steerings, developed by Atlas Copco Controls in co-operation with manufacturers of industrial battery trucks.

A complete steering system includes: - electronic controller, FLY BY WIRE - reference sensor (tachometer) - DC-motor with gear - contactors, fuses and cables The electronic controller is designed to control a fully electric power steering system. There is no mechanical connection between the steering wheel and the traction wheel.

The FLY BY WIRE controller continuously monitors the entire steering system to prevent any hazards. Any faults in the sensor, the cables, the controller or the motor, will result in a fault condition and deenergized safety relay, diagnosed by LED and optoisolated outputs.

When using a fully electric steering system the vehicle has to be stopped automatically if any errors occurs.

This is achieved by connecting the safety relay, in the controller, to an electric brake in the vehicle.

The safety system meets the European: Safety of machinery - Industrial trucks prEN 1175-1 Part 1: Electrical requirements for battery powered trucks.

The power MOSFET transistors controlling the servo motor current provide high efficiency, high reliability and long lifetime. The PWM switching frequency of 16kHz reduces motor losses and provides silent operation.

The controller has current and speed regulators and armature feedback with compensation for motor voltage drop, I*R-compensation.

Cooling is achieved by mounting to a flat metal surface in the vehicle.

The right selection of sensors and servo motors is very important to guarantee reliable operation. Atlas Copco Controls will assit in this matter.

2.10 SAFETY SYSTEM When errors are detected the safety relay opens within 75ms and the controller blocks power output.According to prEN 1175-1 The control is achived by a current pulse which is generated by the safety system with frequency of 15Hz. The pulse passes through the sensor, power electronics and motor circuit. If the pulse disappears or changes shape beyond certain limits the safety system will indicate error.

At every start up the safety system is checked by an error simulation. It takes max 0,3 sec.

If the controller is stopped (turned off) it has to be >2 sec. before a new start up.

Overhead guard and load support Trucks driven sitting or standing and that are capable of lifting a load higher than 1.8 m must be equipped with an overhead guard. Modifications to the overhead guard that could possibly weaken its structure are not allowed. If it is possible for objects to fall through the openings in the overhead guard, the size of the openings must be reduced.

Trucks used for transporting small objects or unstable loads must be equipped with a load support.

5

3. Operating environment Use the truck in dry, indoor facilities with hard, even and level floors. The temperature range in which the truck can continuously operate is +5 to +25°C, and for short periods +0 to +45°C. If the operating temperatures differ from the above mentioned, contact your truck dealer to obtain a separate machine designed for cold and freezing temperatures. A special machine for freezing conditions can be used in temperatures down to -35°C. This truck conforms to all the relevant requirements of the EU machine directive and thus has a CE marking.

Never use the truck: • To transport and lift people • At premises with risk of fire • At premises with risk of explosion • At premises with insufficient floor load capacity • If it is damaged • As a mounting surface • To tow another truck • Under the influence of intoxicating substances

Free space Make sure that the truck has sufficient moving space with respect to overhead structures. Before driving through aisles or door openings, ensure that there is enough space for the truck, the load and yourself.

NOTE: Always drive at a safe distance from the edge of loading platforms or bridges.

Bearing capacity of the floor Make sure that the combined weight of the truck and the load does not exceed the bearing capacity of the floor.

Using elevators You need permission from the site supervisor to use an elevator to transport the truck between floors. Make sure that the combined weight of the truck, the load and yourself does not exceed the maximum load capacity of the elevator. Always drive the truck into elevators and any other narrow spaces with the load in front.

NOTE: Make sure that there are no people in the elevator when driving the truck in or out. The parking brake of the truck must be on before the elevator moves.

Working on ramps You need permission from the site supervision to drive on a slope or ramp. When the truck is loaded, travel with the load pointing uphill. Without a load, you can travel with the forks pointing downhill.

NOTE: Do not turn the steering wheel abruptly on a ramp; the truck might overturn.

Working on loading bridges Always check the bearing capacity and the fastening of the bridge before loading or unloading. If you need to drive the truck onto another vehicle, ensure that the vehicle cannot move during this procedure. Do not drive to the edges of a loading bridge because there is always a risk of overturning.

4. Operating devices Identification plates on the truck Check that the plates are legible and securely attached.

Type plate The truck's type plate is marked with: • Manufacturer • Type of truck • Year of manufacture • Serial number • Truck's dead weight in operating condition, without battery or accessories • Maximum and minimum battery weight • Battery terminal voltage • Truck's nominal lifting capacity • CE mark Capacity plate The capacity plate states the maximum lifting capacity at the maximum lifting height and the lifting height with the nominal lifting capacity. In addition, the plate states the centre of gravity distances for the relevant lifting capacity.

WARNING! Do not overload the truck.

Capacity plate for accessories Detachable accessories affect the truck’s lifting capacity. If the truck is used with detachable accessories, corresponding capacity plates must be attached to the truck.

Safety pedal To operate the truck, first press the safety pedal on the floor with your foot down to the drive position. The truck will not move if the pedal is not pressed.

Brakes Operating and parking brakes The parking brake is a magnetic brake which switches on automatically when you lift your foot from the safety pedal.

CAUTION! The truck will stop abruptly if you release the safety pedal during high travelling speed.

Use the accelerator to brake during normal driving. Remember to handle the accelerator gently.

Motor braking charges the battery and slows the truck in the following cases: 1. When changing direction 2. When the truck is free-wheeling Practice braking with a load in a safe area before you start working with the truck.

7

Control panel Key switch (1) The key switch connects the truck's electrical equipment to the battery circuit.

0 = Power off (the power is still connected to certain electronic devices) 1 = Power on When the power is switched on, an automatic warning light test takes place ensuring that the warning lights and flashers work properly.

Accelerator (2) Turn the accelerator handle forward or backward to the driving direction. A larger movement of the handle produces a higher speed. The accelerator returns automatically to the central position when it is released.

You can brake smoothly by moving the speed control to the direction opposite to the driving direction. You should anticipate the situation when you must brake and decrease the speed well ahead.

You can also use the lever on the side of the truck to move the truck slowly forwards or backwards. First you need to straighten the drive wheel.

Horn button (3) Steering wheel (4) The steering wheel turns the drive mechanism electrically 360°, see Section "Electronic steering system" in Chapter 5.

Emergency stop button (5) Press the emergency stop button to switch off the power circuit of the battery. Use the button in the following cases: • A short-circuit or other electrical fault, for example, if the pump motor runs continuously • In an accident Release the emergency stop button by turning it clockwise.

Lever for lifting and lowering the lift cabin and forks (6) Use the lever on the control panel to lift or lower the lift cabin and forks. You can also use the lever on the side of the truck.

Lowering of the lift cabin and forks is automatically stopped when their height is 200 mm. To lower the lift cabin and forks all the way down, first lower them to 200 mm and release the lever. Then use the lever again and lower the lift cabin and forks to the lowest position.

Controls on the side of the truck Lever for moving the truck forwards and backwards Use the lever on the side of the truck to move the truck forwards and backwards when you are not standing on the platform. Make sure that drive wheel is straight before operating the truck from the side.

Lever for lifting and lowering the forks You can lift and lower the forks also with a lever on the side of the truck when you are not standing on the platform.

NOTE: When the light is lit, the magnetic brake goes on automatically.

Parking brake indicator light (2) The parking brake indicator light indicates that the brake is on.

Drive direction indicator lights (3) The indicator lights indicate the driving direction of the truck.

Hour meter (4) The hour meter counts the time that the truck has been in active operation. It is always on when the electrical devices are operating.

Battery discharge indicator (5) The battery discharge indicator shows the level of the battery charge and stops the lift if the battery charge is too low. However, you should recharge the battery before the charge drops too much. For instructions, see Section "Recharging the battery" in Chapter 7.

Fault monitoring of the speed and pump controls Certain circuits of the truck have automatic fault monitoring, which gives a warning of faults in the drive speed and pump controls. If a fault occurs, the truck cannot be driven until the fault has been eliminated. If the truck does not begin to move and no obvious fault can be found, switch off the power, wait about 5 seconds, then switch on the power again (in this case, do not touch the drive or load controls). If the fault continues, contact maintenance. If fault monitoring finds a fault during operation and stops the driving, stop the truck immediately.

Recharging plug The truck's recharging plug has a handle and can be detached. See Section "Recharging the battery" in Chapter 7 for instructions on using the plug to recharge the battery.

5. Driving instructions Daily checks before operation Carry out the daily maintenance check before using the truck. Neglecting daily maintenance may decrease the safety and reliability of the truck. Notify the site supervision immediately if you notice an error or deficiency during the check.

• Check the truck externally to see that there are no oil leaks.

• Check all wheels for damage or wear.

• Check the battery fluid in each battery cell. Top up with battery water if needed. The fluid surface should be about 15 mm above the plates (this does not apply to maintenance-free batteries).

• Check the gearbox for leaks. Also check the hydraulic pipes, hoses, and connectors. No leaks or damage should be found.

• Switch on the power and test the operation of the lifting hydraulics by raising and lowering the forks.

• Check the operation of the accelerator and steering by driving slowly forward and backward.

• Also check the operation of the other electrical functions.

• Check that the batteries are charged and locked in place.

• Check the operation of the horn.

• Check that the safety pedal works and that the parking brake functions properly.

• Check that the emergency stop operates properly.

• Check that the hoses and cables run freely and are not damaged.

Before you start: • • • • •

Make sure that the daily maintenance has been carried out.

Switch on the power.

Check the driving direction from the indicator lights.

Grip the steering wheel knob with your left hand and the accelerator with your right hand.

Take a position where only one foot is on the safety pedal.

Driving • • • •

Press the safety pedal down to move the truck.

Turn the accelerator lightly in the driving direction.

To brake, turn the accelerator in the opposite direction to the driving direction.

Steer the truck smoothly because abrupt movements may cause a dangerous situation, especially when driving at high speeds.

• Always drive with the lift cabin lowered when not in the collection aisles.

Electronic steering system The truck is equipped with a fully electronic steering system. The steering wheel movement is transmitted without a mechanical connection to the steering motor that controls the drive wheel.

The system consists of three main components: 1. Tachometer located in the steering wheel 2. Control unit located in the motor compartment 3. Steering motor, which is also in the motor compartment The control unit processes the signal coming from the tachometer and directs the steering motor to turn the drive wheel in the desired direction. In addition, the control unit constantly monitors the status of the system and reacts immediately if there are any problems.

NOTE: Do not turn the steering wheel unnecessarily when the truck is not moving.

Safety When the power is turned on from the key switch, the system performs a self-diagnostic test. The test lasts for less than a second, after which the truck is ready for operation.

When the power is on, the control unit sends continuous diagnostic check signals throughout the system. This signal can be heard as a tapping noise emitting from the truck. In case of a system malfunction, the control unit will react immediately to the situation by switching off the drive operation and turning on the magnetic brake, and the truck will stop.

Problems in electronic steering or in the control system are indicated by the red STOP warning light. The truck does not drive if the light is on.

10

Wait for at least 2 seconds before you switch on the power again after it has been switched off by the system. If the red warning light does not go off after switching the power off and on again, there is a problem in the steering system and the truck cannot be driven.

Maintenance of the electronic steering system The system has been designed to be as maintenance free as possible. The quarterly maintenance check (300 hours) includes the fastening of the steering control unit terminals.

NOTE: The control unit is configured at the factory. Do not attempt to adjust it. An authorised service person can tune the steering, e.g. the number of rotations for the steering wheel, if necessary.

General driving instructions Practice steering and controlling the truck carefully in a safe area.

• Drive slowly at intersections and when turning.

• Handle the truck responsibly and always keep it under control.

• Avoid sudden starts and stops.

• Steer and brake smoothly.

• Decrease the speed if the floor is slippery, for example, because of humidity.

• Take great care when driving on a slanted surface.

• Do not drive over any loose objects on the floor.

When driving, keep the load lowered and, if possible, tilted backwards. Do not lift the load except when stacking.

This does not apply to trucks designed to be driven with the load raised.

Be especially careful: • When there are other people or objects in the working area • When the load reduces visibility • When driving in narrow aisles make sure that there is enough space for the truck and the load

Driving position When moving forwards, stand firmly with one foot on the safety pedal. Keep your left hand on the steering wheel and your right hand on the accelerator handle.

When driving, always keep your body completely within the outlines of the truck. Anticipate any dangers so that you can avoid risks of accident or injury.

Speed Control the speed according to the situation. Take into consideration the load, visibility, and people in the working area and the working environment. Slow down at cross aisles and whenever the vision is obstructed. If the visibility is inadequate, use an assistant to help guide you.

Uncontrolled acceleration or braking, excessive speed at turning points, and fast and sudden turning may overturn the load and cause an accident. In all conditions, drive the truck at a speed that enables you to stop it safely.

Parking Park the truck in a reserved parking place. When parking the truck, the forks must be lowered and the parking brake must be on. Ensure that the truck cannot move by itself or that an inexperienced person cannot start driving it under any circumstances.

NOTE: Never park or stack goods in front of fire doors, fire extinguishers, emergency exits and the like. Do not park on a slanted surface.

Traffic rules Maintain good visibility in the driving direction and keep sufficient safety distances. Follow the traffic regulations and speed limits. Do not drive the truck outside a private area without an order or permission from the site supervisor. Outside a private area, the truck is subject to general traffic rules and regulations. If a door opening is so narrow that two trucks cannot possibly pass through it at the same time, drive in the middle of the opening.

When two trucks meet in a narrow or cross aisle, the loaded truck has the right of way.

NOTE: When driving, you should sound the horn when necessary to warn others in the same area.

6. Load handling Only transport a load when it has been safely loaded.

• Always drive the truck with its forks lowered.

• When the load is raised, steer and brake carefully.

• If the truck has side stabilisers, use them when you fetch or leave a load. Raise them when driving.

• Do not let anyone, under any circumstances, walk or stand under the forks.

• Never place any part of your body between the mast structures or any moving parts of the truck.

• When carrying a load larger than the outlines of the truck, take into account the extra space it requires.

• Before stacking, always lower the initial lift to the down position.

• Only handle undamaged loads.

• Place the load correctly.

• On slopes and ramps, place yourself above the load.

• Do not overload.

Lifting capacity The lifting capacity of the truck is printed on the capacity plate. Obey the maximum values for load weight and load center information in different loading situations. Take into account the effect of any attachments on the lifting capacity.

WARNING! Do not exceed the truck's maximum loading capacity under any circumstances.

Collection • Use the lifting and lowering lever to set a suitable collection height.

• If you need to lean far over a shelf, first switch off the power with the key switch.

• Place the load so that its weight is distributed evenly on the lifting forks.

WARNING! A broken pallet or an unstable load must never be left on a shelf or stack, but must always be removed.

7. Batteries Only appointed and trained personnel may replace and recharge batteries. Individuals maintaining batteries must have sufficient protective clothing and eye gear.

• Do not handle a naked flame in the vicinity of batteries because of a risk of explosion.

• Do not smoke when working with batteries.

• Do not leave tools or other metal implements on top of the battery. Sparking or a short-circuit may cause the battery to explode.

• When batteries are recharged, the cell plugs must be closed firmly to prevent splashing of battery fluid.

• The battery fluid is a corrosive acid solution; avoid getting it on your skin or in your eyes. The battery fluid develops an explosive gas at the end phase of recharging. Therefore, make sure that the battery has sufficient ventilation (this does not apply to maintenance-free batteries).

• A low battery charge status may damage the battery during long-time use.

Recharging the battery Make sure that the charger is the appropriate model and that the battery has sufficient ventilation.

1. Park the truck in a reserved recharging place.

2. Switch off the power from the key switch.

3. Make sure that the charger has been switched off.

4. Disconnect the battery connector and connect it to the charger.

5. Switch on the charger.

After recharging 1. Switch off the charger.

2. Disconnect the battery connector from the charger. Grab the plugs; do not pull the cables.

3. Check the battery according to the battery manufacturer's maintenance instructions.

Measuring the specific gravity of the battery cell Measure the specific gravity of the battery fluid according to the manufacturer's instructions. The specific gravity of a fully charged battery is 1.28 to 1.30 at +30°C. • 1.24 3/4 charged • 1.20 1/2 charged • 1.16 1/4 charged • 1.15 empty. Charge the battery immediately.

Replacing the battery Replace the battery according to the manufacturer's instructions.

When reinstalling batteries, use the appropriate tools for moving, connecting and fastening the battery securely. Do not keep the tools or other metal implements on top of uncovered batteries.

When replacing the battery, use one with similar dimensions and weight so that the stability or braking properties of the truck are not weakened. The minimum weight of the battery is indicated on the identification plate of the truck.

When you use a lifting device for lifting the battery, place a nonconductive plate on top of the battery to avoid the risk of a short-circuit. This is not necessary if the lifting device has sufficient insulation and is equipped with a distributor, or if the pole shoes and cell combinations are fully protected.

13

Acquiring a new battery When acquiring a battery for the truck, pay attention to the following sections of the standard EN 1175-1: • 5.1 Traction batteries (includes the requirements for the protective cover of the battery case, ventilation and interior surface treatment) • 7.4 Minimum markings (includes the requirements specified on the truck battery plate) The battery plate should provide at least the following information: • Manufacturer • Type • Serial number • Rated voltage • Capacity (Ah/5 h) • Service weight
