Low condenser air or water
temperature, oil filters obstructed, oil
valve blocked, oil solenoid and oil
pressure transducer defectiveThe 30GX/HXC screw chillers use one externally mounted
pre-lubricating oil pump per circuit. This pump is operated as
part ot the start-up sequence.
ATTENTION: The operating temperature of the coil may
reach 80°C. In certain temporary conditions (especially
during start-up at low outside temperature or low condenser
loop temperature) the oil pump can be reactivated.
On 30GX units, the pumps are mounted to the base rails on the
oil separator side of the unit. The pumps are mounted to a
bracket on the condensers of 30HXC units. When a circuit is
required to start, the controls will energize the oil pump first so
that the compressor starts with correct lubrication. If the pump
has built up sufficient oil pressure, the compressor will be
allowed to start. Once the compressor has started, the oil pump
will be turned off. If the pump was not able to build up enough
oil pressure, the control will generate an alarm.

thanks for the answer but the problem is compressor is running but there is not any action in dischare pressure or suction pressure . even i have change the internal oil filter if there is a problem with oil pump or oil selnoid valve the compressor will not be able to start. but the problem is compressore is start and after one minute it gets trip of alarm 68 and if there is nothing wrong with compressore then pressure should be builup.but there is not any action in pressure and standing is high side is 500 kpa .
thanks in advanced for your answer and your replay
