When the refrigeration system is working, the compressor can made a pressure difference, it caused large load which made the compressor motor output torque is insufficient and cannot start the euipment when the euipment stop and start again, so the euipment should be restart only if pressure balance, our control system adopt the method of delay function to control the compressor on and off, it is called delay start of compressor.
Compressor Delay Instructions
1.The reason of delay starting：
When the refrigeration system is working, the compressor can made a pressure difference, it caused large load which made the compressor motor output torque is insufficient and cannot start the euipment when the euipment stop and start again, so the euipment should be restart only if pressure balance, our control system adopt the method of delay function to control the compressor on and off, it is called delay start of compressor.
2.Allway chiller delay protection instructions
1, Allway chiller gets into E_dL delay protection once power off and reset, compressor normal start after countdown to the end.
2, Allway chiller background timing automaticly, once press the start/stop button, if restart the compressor within the delay time it will display E_dL protection, continue to finish the setting time,then compressor start, if the downtime longer than setting, compressor will start directly.
3.Harm to comperssor without delay
If the delay time does not settled, compressor start stop frequently, may greatly cause compressor locked-rotor, burn down by big instantaneous electric current; Even if not directly burned will lead to reduce compressor life time.
4.Delay time adjusting
If users need to adjust delay time, part of the small devices can be shortened to 100 seconds, but the life of compressor may shorter than the normal delay protection equipment, time delay can not be completely cancelled.
