Why is the Rittal Air Conditioner showing a high discharge gas temperature alarm ALC05?
A high discharge gas temperature alarm (ALC05) on your Rittal Air Conditioner can be caused by a high inlet temperature, a high heat load, or incorrect pipework. To address this, check the operating conditions according to the compressor specifications, verify the device limits, and inspect the pipework.
What to do if Rittal LCP Rack DX 12 shows Compressor 1 overload alarm ALC01?
If your Rittal Air Conditioner displays an ALC01 alarm, indicating a Compressor 1 overload or inverter alarm, it could be due to high inlet temperature, high heat load, incorrect pipework, or incorrect wiring. You should check the operating conditions as per compressor specifications, check the device limits, and inspect the pipework and wiring.
