Compressor overheat protection
(a) Purpose:
It is designed to prevent deterioration of oil, burnout of motor coil and other trouble resulting from the
compressor overheat.
(b)
Detail of operation

Notes (1) When the discharge pipe temperature is in the range of 105~115ºC, the speed is reduced by 4 rps.
(2) When the discharge pipe temperature is raised and continues operation for 20 seconds without changing, then the speed is reduced again by 4 rps.
(3) If the discharge pipe temperature is in the range of 95~105 even when the compressor command speed is maintained for 3 minutes when the tem-
perature is in the range of 95~105ºC, the speed is raised by 1 rps and kept at that speed for 3 minutes. This process is repeated until the command
speed is reached.
