PRODUCT DESCRIPTION

When setting the relay characteristic/torque angle for the three phase directional overcurrent element, a positive angle setting was specified. This was due to the fact that we consider as polarising voltage, the phase voltage value in quadrature of the current under fault conditions. With directional earth fault protection, the residual current under fault conditions lies at an angle lagging the polarising residual earth fault voltage.

Description:

Servicing

The Altivar 12 does not require any preventive maintenance. However, it is advisable to perform the following checks regularly:

• The condition and tightness of connections.

• Ensure that the temperature around the unit remains at an acceptable level and that ventilation is effective. Average service life of 

fans: 10 years.

• Remove any dust from the drive.

• Ensure proper fan operation.

• Physical damage to covers.

Assistance with maintenance, detected fault display

If a problem arises during setup or operation, ensure that the recommendations relating to the environment, mounting and connections have

been observed. 

The first fault detected is stored and displayed, flashing, on the screen: the drive locks and the status relay R1 contact opens.

Clearing the detected fault

In the event of a non-resettable detected fault:

• Remove/cut the power to the drive. 

• WAIT 15 MINUTES to allow the DC bus capacitors to discharge. Then follow the “Bus Voltage Measurement Procedure”, page 14 to 

verify that the DC voltage is less than 42 V. The drive LEDs are not indicators of the absence of DC bus voltage.

• Find and correct the detected fault. 

• Restore power to the drive to confirm the detected fault has been rectified.

Certain detected faults can be programmed for automatic restart after the cause has disappeared.

These detected faults can also be reset by cycling power to the drive or by means of a logic input or control bit.

Display menu

Use the display menu to show the status of the drive and it's current values as an aid for finding the causes of detected faults.

Spares and repairs

Serviceable product: Refer to the catalog for replacement of spare parts. 

Procedure after a long time storage

NOTICE

RISK OF DEGRADED PERFORMANCE DUE TO CAPACITOR AGING

The product capacitor performances after a long time storage above 2 years can be temporarily degraded and therefore following

reforming procedure should be applied. In that case, before using the product, apply the following procedure: 

• Use a variable AC supply connected between L1 and L2.

• Increase AC supply voltage to have: 

- 80% of rated voltage during 30 min

- 100% of rated voltage for another 30 min

Failure to follow these instructions can result in death, serious injury, or equipment damage
