the Driver of the Elecromechanical Brake is short circuited)

and this alarm occurs.

b) When the feedforward PWM is higher than 70% of the

battery voltage, the Actual voltage on the

Electromechanical Brake is expected high. If it is lower than

14V it means the Electromechanical Brake always gets the

truck Braked (probably the Driver of the Elecromechanical

Brake is opened) and this alarm occurs.

- Remedy: Probably it is necessary to substituite the controller because the

driver of the Electromechanical Brake has a failure.

5) MDI VALVE2 SHORT

MDI-PRC Code = 70

- Cause: This alarm occurs on the MDI-PRC and the information is

transferred via CAN Bus to the AC1.

- Remedy: See 14.2 and the manual of the MDI-PRC.

6) MDI NEVP1 NOT OK

MDI-PRC Code = 90

- Cause: This alarm occurs on the MDI-PRC and the information is

transferred via CAN Bus to the AC1.

- Remedy: See 14.2 and the manual of the MDI-PRC.

7) MDI PEV NOT OK

MDI-PRC Code = 89

- Cause: This alarm occurs on the MDI-PRC and the information is

transferred via CAN Bus to the AC1.

- Remedy: See 14.2 and the manual of the MDI-PRC.

8) MDI DRV 2 OPEN

MDI-PRC Code = 75

- Cause: This alarm occurs on the MDI-PRC and the information is

transferred via CAN Bus to the AC1.

- Remedy: See 14.2 and the manual of the MDI-PRC.

9) MDI DRV 2 SHORT

MDI-PRC Code = 74

- Cause: This alarm occurs on the MDI-PRC and the information is

transferred via CAN Bus to the AC1.

- Remedy: See 14.2 and the manual of the MDI-PRC.

10) INPUT ERROR #1

MDI-PRC Code = 92

- Cause: This alarm occurs when the PLD device has a failure. The PLD

device is used for both, the Passive Emergency Cell (see 5.1)

and a Multiplexer on the Main Lifting/Lowering requests. This

Multiplexer exits the Lifting and the Not Lifting level on two

distinct addresses. When the Lifting and the Not Lifting outputs

have the same Logic Level the PLD device has failed and this

alarm occurs.

- Remedy: It is necessary to substituite the controller.

11) ANALOG INPUT

MDI-PRC Code = 96

- Cause: This alarm occurs when the A/D conversion of the analog inputs

gives frozen value, on all of the converted signals, for more
