POWER FAILURE #1 (MDI Alarm 73)
Short-circuit on the ON/OFF valves, or in the main contactor coil, or in the
electrobrake coil.

EEPROM KO (MDI Alarm 13)
Fault in the area of memory where the parameters are stored. This alarm inhibits machine operation. If the fault continues when the Key switch is turned off and on again, replace the logic. If the fault disappears, the previously stored parameters will be replaced by the default parameters.

INCORRECT START (MDI Alarm 79) Traction, (MDI Alarm 95) Pump
Alarm generated by an incorrect starting sequence. Possible reasons:
a) The Enable microswitch has welded or failed.
b) Error in the starting sequence from the operator.
c) Error in the wiring.
d) Lifting operation awaiting when the key is turned on.

CAPACITOR CHARGE (MDI Alarm 60)
This check is made during the initial diagnosis. This Alarm is generated if the capacitors are not charged within 500 mSec after the Key switch on. Probable cause is a failure within the power block.

VMN NOT OK (MDI Alarm 32)
This test is performed at rest, with the Main Contactor closed, and also during operation. This Alarm is generated if the VMN is lower than battery voltage in standby. This alarm is generated if VMN does not follow the duty-cycle of the chopper while driving. Possible causes:
a) Incorrect motor connection.
b) Frame fault of motor to chassis.
c) Defect in the power unit.

VACC NOT OK (MDI Alarm 78)
This Alarm is generated if the accelerator output voltage from the serial tiller is higher than 1V. Possible causes to be checked on the serial tiller:
a) the track of the potentiometer has become open.
b) the potentiometer is not wired correctly.
c) the potentiometer itself is defective.
d) the values set during the acquisition procedure are wrong.

VFIELD NOT OK (MDI Alarm 3)
This test is made in standby with the Main Contactor open. In this condition the voltage on both the connections of field must be around ½ VBatt. This alarm is generated if the field voltage is different from this value. Possible causes:
a) Frame fault on the motor to chassis.
b) Incorrect connection of the field winding to the chopper.
c) Failure of the chopper in the section relative to the field.

PUMP VACC NOT OK (MDI Alarm 4)
This alarm is generated if the lifting potentiometer output voltage from the serial tiller is higher than 1V. Possible causes to be checked on the serial tiller:
a) the track of the potentiometer has become open.
b) the potentiometer is not wired correctly.
c) the potentiometer itself is defective.
d) the values set during the acquisition procedure are wrong.

I = 0 EVER (MDI Alarm 49)
This check is made while driving. If the current is not higher than a preset minimum value, this alarm is generated and the machine disabled. Possible causes: see "STBY I HIGH" alarm.

HIGH FIELD CURRENT (MDI Alarm 57)
Problem detected with the field current sensor. Possible causes:
a) Failure of the field current sensor.
b) Failure of the field power unit.

NO FIELD CURRENT (MDI Alarm 58)
Problem detected with the field winding current. Possible causes:
a) Failure of the field current sensor.
b) Field cables not connected or incorrectly connected.
c) Failure of the field power unit.

DRIVER SHORTED (MDI Alarm 74)
The test is carried out with Main Contactor open. The logic unit verifies that the coil of the Main Contactor is not shorted. Possible causes:
a) Driver shorted.
b) Problems in the feed back circuit of the Main Contactor coil.
c) Wiring error.
d) Fault in the protection circuit.

COIL SHORTED (MDI Alarm 76)
When the key is turned on, the microprocessor tests the overloads protection circuit of the contactor driver. If a problem is detected, this alarm is generated. Possible causes:
a) Failure within the contactor coil.
b) Incorrect wiring.
c) Failure of the protection circuit.

CONTACTOR DRIVER (MDI Alarm 75)
This alarm is generated if there is a problem with the Main Contactor. Possible causes:
a) The Main Contactor coil driver is open-circuit.
c) Defect in the Main Contactor coil voltage feed back circuit.

CONTACTOR CLOSED (MDI Alarm 37)
This check is made before closing Main Contactor. It checks that the driver is not open. Possible causes:
a) the contactor's power poles are not welded.
b) This alarm could be generated if the line contactor is opened, but there is a problem within the field circuit.

FORW + BACK (MDI Alarm 80)
This check is made continuosly. The Alarm is generated when forward and reverse directions are requested simultaneously. Possible causes:
a) Incorrect Wiring.
b) Welding or failure of a direction switch.
c) Incorrect operation from the operator.

BATTERY LOW (MDI Alarm 66)
This Alarm is generated when the battery becomes 90% discharged from the nominal value. If there is the alarm and the battery is not discharged, check the battery value in the "Tester" menu of the console; if it is incorrect, re-adjust via the "Adjustment" menu.

STBY I HIGH (MDI Alarm 53)
This test is made during the initial diagnosis and in standby. The test verifies that the currents are zero. This alarm disables the machine. Possible causes:
a) Defective current sensor.
b) Feed back circuit failure or logic failure or power unit failure.

BRAKE DRIVER KO (MDI Alarm 2)
The alarm is present when there is a problem on the electrobrake driver. Possible causes:
a) driver in short-circuit
b) driver broken, cannot drive the brake;
c) current feedback circuit for the brake coil faulted

EVP NOT OK (MDI Alarm 1)
At stand: proportional valve opened. Running: the proportional valve doesn't follow the applied PWM.

SERIAL ERROR #1 (MDI Alarm 6)
Wrong message or no message from serial tiller

INPUT ERROR #1 (MDI Alarm 99)
No belly switch on the tiller card

INPUT ERROR #2 (MDI Alarm 98)
No belly switch on the controller

THERMAL PROTECTION (MDI Alarm 67)
This alarm is generated if the chopper temperature rises above 77°C, . If this alarm is displayed when the chopper's temperature is the same as ambient:
a) check the connection of the temperature sensor.
