TROUBLESHOOTING
6.1 INTRODUCTION
The information in this section is based on the experience gained by the service activities and tests
conducted at factory.
The indications and reasons of failures are ordered according to the results obtained from the
warnings of our company and the experience of the service personnel.
According to the structure of the compressor, as the systems and failures are interrelated; prior
making any repair or part replacement the reason of failure should be determined.
For the problems to be encountered, it is beneficial to make an eye inspection.
Good Tracing of failure, prevents the undesired damages that may occur during repair.
Firstly;
9
Check the electrical connections for the possibility of looseness.
9
Check the parts that may be influenced from short circuit and heat.
9
Check the damage and looseness that may form at air and oil circuit hoses, pipes and
connections.
If you have tried all the ways described in this handbook for eliminating the failure and the problem
still continues; please contact our company or service department.
From the point of your speed and reliability having all kinds of corrective action,
maintenance and repair works to be done at our service companies is the best way
for your compressor and your facility. All kinds of works carried out without
sufficient knowledge may cause wrong results, unnecessary interruptions of your
facility or more costly damages.
6.2 PROBLEMS AND SOLUTIONS
1-
COMPRESSOR DOES NOT OPERATE
1-
NO ELECTRICAL POWER
CHECK THE VOLTAGE FROM INPUT TERMINAL BLOCK
2- CONTROL OR INPUT FUSE IS BLOWN, MAIN SWITCH TRIPPED
CHECK THE FUSES
3-VOLTAGE IS LOW, UNSTABLE OR OPPOSITE
OBSERVE THE WARNING ON THE PHASE CONTROL RELAY
4-COMPRESSOR HAS STOPPED FOR ANY KIND OF FAILURE
OBSERVE THE WARNING ON THE CONTROL PANEL.
5-OPERATOR TRY TO START WHEN THE DISCHARGING DELAY TIME.
AFTER STOPPING THE COMPRESSOR, IT SHOULD NOT WORK FOR 1 MINUTE FOR
DISCHARGING OF INTERNAL PRESSURE. WAIT FOR “X10” LEDS BLINKING STOP.
2-
COMPRESSOR IS HARDLY WORKING
1- THE CROSS SECTION OF POWER CABLE IS INSUFFICIENT.
THIS PROBLEM CAN BE ENCOUNTERED ON CONNECTIONS MADE THINNER CABLE DUE TO
VOLTAGE LOSS. WHEN YOUR COMPRESSOR IS IN STOP POSITION, MEASURE THE INPUT
VOLTAGE AND WHILE MEASURING RUN THE COMPRESSOR. IF THE VOLTAGE IS DECREASE %
5 (380> 360) AND BELOW, THE CABLE CROSS SECTION IS INSUFFICIENT. MAKE THE
CONNECTION WITH A SUITABLE CROSS SECTION.
2- VOLTAGE IS LOW
IF THE LINE VOLTAGE IS % 5 LESS THAN THE COMPRESSOR ADJUSTED VOLTAGE, THE
PROBLEM MAY ARISE FROM THE NETWORK OR FROM THE ESTABLISHED POWER OF YOUR
FACILITY.
3- THE AMBIENT TEMPERATURE IS LOW
IF THE AMBIENT TEMPERATURE IS LOW THAN + 2 °C, THE OIL MAY THICKEN AND THIS MAY
ENFORCE THE OPERATION OF YOUR COMPRESSOR.
4-INTAKE VALVE IS DEFECTED
THE INTAKE VALVE IS CLOSED AT FIRST RUN UP. IF THERE IS A MECHANICAL PROBLEM, IT
MAY STAY OPEN. THIS WAY THE COMPRESSOR TRIES TO START UP AGAINST LOAD AND
HARDLY SPEEDS UP. WHEN THE COMPRESSOR IS AT STOP AND THERE IS NO INTERNAL
PRESSURE, OBSERVE THAT THE INTAKE CLAPET IS FULLY CLOSED. THE CLAPET MIGHT BE
STUCK AT OPEN POSITION. INFORM THE SERVICE.
5-THERE IS A MECHANICAL PROBLEM AT MOTOR OR COMPRESSOR UNIT
