    drive mode manually, please perform the switching in stop status of the screw compressor. Otherwise, short circuit may occur to electric arc at the output side of the inverter. If you operate the main motor’s inverter/power-line switch (X1) when screw compressor runs, the controller will make the screw compressor emergency stop.

    Figure 5-1 Control process in the MDI drive mode After the MDI drives the main motor to run for 2 seconds, the controller opens the open the intake valve and adjusts the air outlet pressure through the PID operation. In normal running status, once you press the “Stop” command key, the controller will immediately turn off the solenoid valve to shut down the intake valve and reduce the output frequency of the inverter to lower limit of frequency, which makes the screw compressor continue to run...

  • Page 47: Control Of The Fan

    Because the screw compressor prevents reverse rotating, the controller will detect the phase sequence of the AC power supply of the compressor. If the phase sequence is abnormal, the controller will give an alarm and stop the system from entering running status. To reduce the surge current during startup of the motor, when the motor capacity is big, we usually use Y- startup mode.
