Hi Sir, In a carrier 30 XA chiller, when is there a need to replace an oil level switch ( float switch), can you please explain exactly. Regards Derek
Hello. The oil level switch works ok dry contact principal. If the oil level is good in the chiller oil level switch contact should be closer. In case oil level is ok and oil level switch contact is open then replace the switch

can you go over understanding the prints on an AHU. How to know exactly where devices are going on the ahu by looking at the print
Sure, will upload a video soon .
What about when you get the "unable to read from selected device" error on a new sensor and nothing seems to make it read? It says it's not communication but I can turn the LEDs on and off.

How to remove copper winding
How many days does it take to change chiller oil?
The simple answer is between 1 to 3 days. Here is the detailed answer. It depends on the chiller size and type. For air cooled chillers oil separator is accessible. You can just pump down the chiller and drain oil. Change oil filter and change oil in just 1 days. But if the chiller doesn’t have valve to isolate or pumping down is not possible than you have to add 2 extra days for refrigerant recovery and vacuum.
How can we change cards of EEV.... when not find same type. Like we change it from danfoce to sporlan
As far the valve specifications i.e Volatge Steps Hertz Milli amps Are same as the old one you dont need to change the card Secondly its not possible to install another type of card . As the rest of the cards in the chiller will not communicate with new type of card. If you are replacing the card is must be same as old
Very good explanation
Thank you.
Can you please tell me the override error in 30xA080-501 Air cooled liquid chiller
Please confirm what is the alarm code showing in the display? Or its just showing override ??

30xa chiller what is setting MTAsetting it is FLA OR RLA.
MTA setting is for must trip amperes . In case compressor draw current morethan the mta setting it will trip the compressor Fla and rla are not controlled by MTA
los of communication with exv board number a chiller 30xa
Please check the following. 1: EXV Board Green light should once in 1 second and red light should blink twice in 1 second ( if lights are blinking differently it could be the software issue or board is faulty) 2: Confirm the board address ( Dip switch settings) are correct 3: Communication in and out terminal make sure are clean and well connected on the EXV board and main processor board. thanks for your comment.
How to deal with Low Discharge Superheat
You can start Troubleshooting with the following. Make sure all other compressors are off in the chiller and only the compressor having alarm of low discharge superheat is working. 1: Check the Discharge Pressure Transducer. 2: Check Discharge Temperature sensor 3: Check Expansion Valve Operation ( If it is opening as required) 4: Check Discharge pressure 5: Check suction pressure 6: Check inlet water Temperature and Outlet Water temperature ( outlet water should not be below 6 Centigrade ) 7: Check compressor capacity ( what percent load it is working on before trping) If any of the above parameters are out of range correct them and your alarm should be cleared.

We have Trane RAU 500 & 600 Air cooled Condenser Units. On RAU500 It is showing COMM LOSS: ....... For every transducers and temperature sensors. First I thought that the card might be faulty so I replaced the power communication card from RAU600. But still it's the same.
Thanks for your comment, Basically in Trane units each time you disconnects or install a new sensor / Transducer you need to bind it using the trane techview below is the link of the video on how to bind a device after replacement in Trane units th-cam.com/video/OPCBo4IZ37s/w-d-xo.html
