Falla Eléctrica Común y Causas

FAILURE

CAUSES

MEASUREMENT TO TAKE

Air Exhaust Temperature too high

Bad vent condition, Oil lacking etc.

Check the vent condition and lubricant amount etc.

Temperature Sensor Failure

Cable off or PT1OO damaged

Checking the wiring and PT100

Over Pressure

The pressure too high or the pressure sensor failure

Check the pressure and the pressure sensor

Pressure Sensor Failure

Cable off, Sensor damaged or the cable connected reversed

Check the wiring and sensor transformer

Water Lacking

Water Pressure switch damaged

Check the water pressure switch

Phase Lacking

Power phase lacking or the Contactor terminal damaged

Check the power and contactors

Overloaded

Voltage too low, tubes blocked, Bearing Wear off or other mechanical failure or wrong set data etc.

Check the set data, Voltage, bearings, tubes and other mechanical systems.

Unbalance

Power unbalance, Contactor damaged or the internal open of the motor

Check the power, contactors and the motor

Rotor Lock

Voltage too low, tubes blocked, Bearing Wear off or other mechanical failure or wrong set data etc.

Check the set data, Voltage, bearings, tubes and other mechanical systems.

Short Circuit

Wrong Wiring, Incorrect Data setting etc.

Checking the wiring and set the data correctly

Wrong Phase Sequence

Reversed Phase sequence or phase off

Check the wiring

Fan stopped

Fan damaged, Contactor damaged, no control output

Check the wiring and control output

Overload or Rotor locking during starting process

Host start time set to a value less than the star angel time delay

Reset the host starting time to be longer than star angel delay + Load delay time

The main Contactor activate time to time

The emergency button loose

Check the wiring
