Troubleshooting and fault elimination

The four LED's in the cover of the power feedback unit display the operating

condition. For easier visibility during service and first powering up similar

LED's are placed on the control board. Unlike to the cover on the control board

there are separate orange and green LED’s, whose function in the cover are

served by a bicolour (green/orange) LED.

Stop:

If the power feedback unit trips during a retardation, it must not be reset until

the end of the retardation and until the DC-bus voltage has fallen to normal

values.

To avoid any kind of problems you can block the impulse-release of the in-

verter by connecting the collective-error-relay-contact of the power-feedback-

unit with the corresponding connection of the frequency inverter.

-tripping:

The power feedback unit trips by the U

-protective-circuitry, if the specific

maximum current of the device is exceeded. The principle of this protective-

circuitry implies that for a short time (less than one millisecond) the IGBT is

stressed over its specification for normal operation. For an single case this

means no problem for the power feedback unit. However, if the over current

cut off arises often or even periodically, the high power semiconductors will

age very rapidly and fail premature.

The cause of periodical U

cut offs may be over load, under voltage in the

network, a defective or oscillating controller, an oscillating reference input or a

wrong design of the plant.
