2.10 STATUS DISPLAYS
By default the line pressure (P2) and discharge
temperature (T1) are shown on the bottom line of
the display, and machine status on the top line.
The following are the various machine status mes-
sages that indicate the state of the compressor:
(Display graphics shown below.)
S
STOP --- Compressor is off.

The machine may start at any time.
S
STARTING --- Machine is trying to start.
S
OFF LOAD --- Machine is running and off
loaded.
S
ON LOAD --- Machine is running and
loaded.
S
FULL LD --- Machine is running and fully
loaded. This state is only displayed if the
machine has a full load valve.
S
RMT STOP --- Compressor is off but
armed to start. The machine will start when
the remote start contact is closed. NOTE :
the machine may start at any time.
S
SEQ STOP --- Compressor is off but armed
