Note:
When the compressor is running according to its own set point the compressor will never adjust the
pressure down to "P-SUCT. RELIEVE" or "P-SUCT. CUTOUT" because of "P-SUCT. STOP". It will
only be possible to achieve these two pressures if the compressor is running at manual control, or at
remote control according to external set point. As "P-SUCT. CUTOUT" is resetting itself when the
pressure has again exceeded set point for "P-SUCT. CUTOUT" the compressor will start at "remote
control operation according to external set point". At manual operation the key for start of compressor
has to be pushed again.
