Name in the manufacturer's documentation (service manual): Low pressure protection (for some models)[1]

In plain words (editorial)

Low pressure protection: the outdoor pressure switch cut off the system because the low pressure fell below 0.13 MPa. The manual names the connection wires, the outdoor PCB, the low pressure protector or the refrigerant.

When to call a service technician: Contact an air-conditioning service technician.
