How do you stop the second compressor in a 7.5 ton dual compressor unit from cycling on and off every 10 seconds?
I assume that it is an air compressor (dual units - two compressor motors) used to provide pressurised air to operate some valves and devices in a industrial plant. (Because it is not clear in the question) Normally the compressor is designed to operate in "load and unload " mode through few solenoid valves, if not equipped with Variable frequency Drive. If the compressor is equipped with variable frequency drive, then it is designed to run in "load and Unload" mode using the VFD for variable speed to switch between load and unload mode. In both the cases, load and unload mode are trigged by pressure switches or pressure transmitters at a preset differential values. Air compressor runs on "load" mode till pressure reaches the preset maximum value. It then switches to "unload" mode till the pressure reaches the minimum preset value. Once the minimum value is reached, it switches again on "load" mode. The cycle continues, but motor does not start - stop during these modes. Air pressure is a function of consumption in the usegae points, which keeps on reducing gradully basis the consumption. How quickly or slowly the pressure reduces - depends on the rate of air consumption. There could be several reasons for the second compressor to go on - off every 10 second. Check the "load - unload" pressure setting on the conmpressor. Increasing the differential setting a bit more, will increase the on-off cycle time. Check the requirement and data sheet before doing so. Check the consumption, whether it is genuine or waste (air Leakage). Check what is happening the first compressor. If it runs on "load" mode all the time then the actual consumption is just more than the capacity of the one compressor, hence the second one comes on but goes off every 10 seconds, since the consumption is just slightly above the first compressor capacity. If the waste or leak can be arrested, only one compressor can manage the load, most of the times. Check the control philosophy the compressor, whether it is designed to go on - off or it is designed to switch between load and unload mode - corresponding to differential pressure setting. (Generally Load and unload mode does not turn the motor on and off, but during unload mode, it keeps running at almost no load current and during load mode it takes normal load current)
