3745

Mist lubrication unit

        The mist lubrication unit failed (for oil-mist turret

       lubrication types).

       [Code]

       2->The turret oil-mist drip sensor switch kept ON for 30

          second or longer.

       3->The turret oil-mist drip sensor input kept OFF through

          successive two cycles, each cycle starting witn the

          oil-mist turret lubrication pump drive air ON signal ON

          and ending with this signal OFF.

       4->The initial dripping at power-up by the oil-mist

          lubrication unit has not been completed

          (for oil-mist turret lubrication types).

       5->The oil-mist turret lubricant level alarm/switch kept OFF

          for 3 second or longer.

       [Probable Faulty Locations]

       4->If the initial operation for dripping oil is not completed

          when the power is supplied to the turret oil-mist

          lubrication system, the M-tool spindle is not lubricated,

          and so it cannot rotate. Initial operation for dripping oil

          is executed each time the power is supplied. If this alarm

          occurs, turn OFF the power and then turn it back ON to

          execute initial operation. When the power is supplied, the

          turret oil-mist lubrication pump drives the air unit. The

          interval from ON to OFF of the output signal indicating

          this pump operation is regarded as one cycle. One cycle is

          executed in one second. The turret oil mist drip sensor

          input should come ON at least one time in one cycle until

          the number of cycles reaches 100. When the sensor input

          comes ON in three cycles successively, the initial

          operation is completed. If the initial operation is not

          completed within 100 cycles, this alarm occurs. If this

          alarm still occurs after retrial of initial operation, the

          oil mist lubrication unit may be faulty.
