Can you tell me why this dLL sign keep coming even this is Brand new unit but the fan is from old Unit

[@TropicSupply]

Hi @Riteshpatel7283 ! The discharge line temperature has exceeded its temperature limits too many times and has thus locked the unit out. You will need to go to Copeland Mobile and look up Application Engineering Bulletin # AE8-1376.

EMERSON DİXELL KADAR DEVAM EDİYOR OLARAK KABUL

[@NenoPetrušić]

Hello, can someone explain to me what is PL alarm od Emerson compressor? Tnx

[@TropicSupply]

The closest alarm we can find is "HPL" - Copeland has said the following - System operation causing high discharge pressures (HPL) or high discharge line temperatures (DLL) repeatedly - check system operations. To clear an HPL or DLL lockout, hold the start button for 3 seconds 2 consecutive times, or cycle power to the unit. If using the reset button, the alarm condition will have to clear (DLT temperature drops or Hp switch resets) and any minimum off time will need to complete (5 minutes for the fixed Hp switch). (HPL) high discharge pressures lock alarm is displayed if 5 repeatedly HP alarms occur within 1 hour. We hope this helps!
