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.
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 causes the high pressure compressor 1 alarm ALB02 on a Rittal Air Conditioner?
If your Rittal Air Conditioner is showing a high-pressure alarm (ALB02) for compressor 1, it may be caused by a high ambient temperature, incorrect coolant filling, or a defective fan. Check the device limits, verify the coolant volume, and ensure the fan is functioning correctly.
Why is my Rittal Air Conditioner displaying a high condensing temperature alarm ALD08?
If your Rittal Air Conditioner displays a high condensing temperature alarm (ALD08), it could be due to a high ambient temperature, incorrect coolant filling, or a defective fan on the condenser. Check the device limits, verify the coolant volume, and inspect the condenser fan.
How to fix ALA03 alarm on Rittal LCP Rack DX 12 Air Conditioner?
If your Rittal Air Conditioner displays an ALA03 alarm indicating that Probe B3 is faulty or disconnected, it could be due to sensor failure or the sensor not being correctly connected. Check the connection on the motherboard or replace the sensor.
What to do for EEV motor error alarm ALD03 on Rittal LCP Rack DX 12 Air Conditioner?
If your Rittal Air Conditioner is showing an EEV motor error alarm (ALD03), it may be caused by incorrect or missing wiring between the motherboard and the valve motor. Check the connection on the motherboard or replace the valve motor.
How to fix ALA02 alarm on Rittal LCP Rack DX 12 Air Conditioner?
If your Rittal Air Conditioner displays an ALA02 alarm indicating that Probe B2 is faulty or disconnected, it could be due to sensor failure or the sensor not being correctly connected. Check the connection on the motherboard or replace the sensor.
What does Rittal Air Conditioner Power+ Generic Alarm ALL02 mean?
If your Rittal Air Conditioner shows a Power+ Generic Alarm (ALL02), it could be caused by over or under current, over or under voltage, or over or under temperature of the drive of the compressor motor. Check the cable and any previous high-pressure alarm. Refer to the drive manual "code [105]" for more information.
What to do if Rittal Air Conditioner displays low pressure differential alarm ALC06?
If your Rittal Air Conditioner displays a low-pressure differential alarm (ALC06), indicating insufficient lubrication, it could be due to operating conditions outside of compressor specifications or device limits, a blocked compressor, or incorrect wiring. Check the operating conditions as per compressor specifications, verify the device limits, and check the wiring.
