READ THE OPERATING AND MAINTENANCE MANUAL

Service of the Console

The console allows to:

-set the chopper card for a personalised behaviour of the traction motor

-read the type of the alarm for a correct and easy trouble shooting

-test the different electric values and the state of the electric circuit relative to the traction

Use of the Console

The use of the instrument is very easy and comparable to one of the most common electronic devices

(such as mobile phones).

The sequence to follow always for the console connection is:

1. SWITCH OFF THE GENERAL KEY of the machine

2. take off the connector E from the chopper

3. connect the console in place of the connector E. If the operation connection results to be difficult,

check that the connector is positioned in the correct direction.

4. switch on the key and work with the console

5. quit from all the programs (main menu of the ignition) and SWITCH OFF THE GENERAL KEY of the

machine

6. disconnect the console connector and plug in the connector E

THE WRONG OPERATION SEQUENCE CAN EASILY COMPROMISE

THE FUNCTIONALITY OF THE CHOPPER CARD OR OF THE CONSOLE

Menu of the Console

HEADING: the features of the console and of the chopper card: voltage and maximum current of the

chopper card, the working hours of the chopper card.

PARAMETER CHANGE: in this menu the parameters can be changed to personalise the machine. The

parameters that can be modified are : CUT BACK SPEED 1 (minimum speed machine) and the CUT BACK

SPEED 2 (medium speed machine). All the other parameters are decided in Fimap and they are

related to the traction motor. It is forbidden to change them without previous Fimap

authorisation.

TESTER: the quantities of the electric characteristics (traction motor voltage, state of power switch =

closed/open ...) are showed in this menu.

SAVE: this permits, once the parameters have been changed, to enter the new setting in a storage

location of the console.

RESTORE: this permits to restore on the chopper card a parameter setting which has been entered in

the console.

ALARMS: indicates a list of the last five alarms occurred on the machine. According to the alarm a

specific corrective action is adopted (see following paragraph).

PROGRAM VACC: this section is used to teach the chopper about the potentiometer which is assembled

on the machine. It is an operation to be carried when there is the alarm Vacc not ok, when the

pedal accelerator is being replaced, when the chopper card is being replaced. A wrong relation

between the potentiometer and the chopper card causes the machine stop.

Alarms and Decoder

The chopper card visualises an anomaly on two levels of information

1. through a red alarm led which blinks for a quantity of times relative to the type of anomaly

2. through a message on the console that specifies more details on the nature of the anomaly.

Following table reports for each alarm the possible anomaly and of how to proceed on the machine.

DIAGNOSIS LIST ALARMS

(for better understanding of the list refer also to the electrical layout)

Number of

blinkings MESSAGE NOTES

1 WATCH DOG

The test of self-diagnosis of the chopper card carried

out both on rest as in drive verifies an anomaly

Possible causes

-the logic of the chopper card is damaged

Actions

-replace the chopper card

1 EEPROM DATA KO

The data of the hourmeter inside the chopper card

Actions

-switch off and on again the key. If the problem will be

solved the counter will be reset.

1 EEPROM OFF LINE

The data of the hourmeter and of the alarm stored in

the chopper card are not correct

Actions

-switch off and on again the key. If the problem persists

replace the chopper card

-if the problem will be solved the data will be cancelled

1 EEPROM PAR KO

The memory of the chopper card has lost the

adjustment and operation data

Actions

-switch off and on again the key. If the problem persists

replace the chopper card

-if the problem will be solved the data will be replaced with

the standard data

Number of

blinkings MESSAGE NOTES

2 INCORRECT START

Incorrect starting sequence

Possible causes

-error in the sequence Key/drive selection made by the

operator

-the micro pedal and/or micro drive are stuck

-wiring not correct

Actions

check the starting sequence which is:

-switch on the key

-select drive (forwards/backwards)

-press the accelerator

-check that the drive microswitch and the manipulator

forward/backward traverse selector do not have the

contacts stuck and that they work correctly

-verify the continuity of the circuit that connects the micro

drive pedal, the chopper card and the drive manipulator.

3 VMN LOW

The first check recognises a voltage VMN lower than the

25% of the battery voltage

Possible causes

-wrong connections on the motor

-motor current leakage to the ground

Actions

-check that the motor terminals are well isolated from the

motor casing both inside and outside the motor. Verify that

there is not dirt that causes current leakage between the

terminals and the motor body

-verify that the motor is not wet and in case dry with an air

flow

-check that the connections on the motor and on the

chopper card are correct (verify the type of traction motor

assembled, the correct wiring and the connections on the

chopper VMN, positive and negative)

if the problem persists replace first the chopper card and, if

necessary, also the motor

3 VMN HIGH

Starting test check possible faults on the power circuit

branch .

Possible causes

-chopper power branch damaged

-MOSFET logic control damaged

Action

-replace the chopper card

4 VACC NOT OK

The chopper card recognizes an anomaly in the mechanical

stroke of the accelerator

Possible causes

-the operator switched on the machine with the

accelerator pressed down or he pressed down the

accelerator before the selection of forward or backward

traverse

-the seat microswitch does not work

-the potentiometer and/or the chopper card has been

changed and the relating values between the two

components are to be re-programmed

-a cable between the potentiometer and the chopper card is

interrupted

-the potentiometer is faulty

-the PROGRAM VACC (see chapter Adjustment and

Inspection) has not been carried out correctly

Actions

- check the correct sequence to get traverse

-check the continuity of connections between the

potentiometer accelerator and chopper card

-re-program the chopper card with PROGRAM VACC (see

chapter Adjustment and Inspection)

- check the functionality of the potentiometer (it could be

broken) and replace it if necessary (re-programming then

the chopper card)

5 I HIGH AT STAND

The chopper card tests if on rest the signal of the

current is zero. Otherwise, it blocks the traction

Possible causes

-defective current sensor

-fault in the feedback circuits, or in the logic or on the

chopper card

Actions

- replace the chopper card

6 NPOT NOT OK

Test on working condition: the negative point brings is

at a wrong

Possible causes

-the potentiometer is not well connected to the chopper card

-potentiometer defected

Actions

-check the good connections potentiometer – chopper card

-check the potentiometer efficiency

7 TH PROTECTION

The chopper card works out of the temperature range

(-30°C + 70°C)

Possible causes

-chopper card faulty

-the machine runs in braking condition and the chopper gets

overheated

Actions

-check the temperature of the site where the machine works

-check the consumption of the traction motor

8 DRIVER SHORTED

COIL SHORTED

The driver that controls the driver power switch do not

operate properly

Possible causes

-the driver is defected

Actions

-replace the chopper card

permanent

blink

BATTERY LOW

Battery level too low: the chopper card cuts the power to the

traction motor for its safeguard

Actions

check the charge of the batteries

check the cleanliness and the good connections on the

chopper card of the cable that come from the battery

permanent

switched on FORW BACK

The alarm is indicated when both the forward and backward

requests are activated simultaneously

Possible causes

-wiring not correct

-microswitch forward or backward stuck

Actions

-check the correct functionality of the contacts of the

manipulator

-verify the wiring relative to the manipulator

-if the defect persists replace the chopper card
