hi sir,

we are having zt-200 compressor unit we have faced the problem of starter feedback and then we cleaned the contactors with CRC and we tightened all the signal cables from PLC module now the starter feedback problem is rectified.

again we got the vibration sensor error and we cleared that too then we started the compressor it is running good.

after 2-3 hrs the compressor display showing MOTOR STOPPED.

but we don't get any fault alarm. and again we start the motor it is stopping after some time. there is no faulty alarm this is happening frequently. what may be the problem
