4.4 COMPRESSOR STATE
— Indicates to which compressor the displayed data refers (U:1 = Master; U:2 =
Slave 1; U:3 = Slave 2; U:4 = Slave 3)
— Indicates the actual inverter compressor speed value
— Indicates the actual status of the inverter compressor; this adjustment can be:
Stopped = the compressor is stopped;
Starting = the compressor is starting;
Running = the compressor is running;
Stopping = the compressor is stopping;
Warning = the compressor is in possible error phase;
Critical = the compressor is under critical functioning;
Alarm = the compressor is stopped for alarm;
— Indicates the actual area (relative to the compressor operating range) in which
the compressor is working; this area can be:
OK = optimal functioning;
SLDL = low intake and ow temperatures;
SL = low intake temperature;
SLDH = low intake temperature and high ow temperature;
DH = high ow temperature;
SHDH = high intake and ow temperatures;
SH = high intake temperature;
SHDL = high intake temperature and low ow temperature;
DL = low ow temperature;
— Indicates the status for the immediate compressor block control (communicat-
ed both via serial and as status of the C4 digital output on the J13 terminal
connected via isolation relay to terminals 6-7 of CN11 on the inverter; Open =
blocked):
NO = compressor block; YES = compressor not blocked;
— Indicates the status of the alarm summary:
NO = no alarm; YES = alarm(s) present;
— Indicates the status for compressor enabling:
NO = compressor not enabled; YES = compressor enabled;
— Indicates the status of the compressor normal functioning (on and outside the
initial ramp):
NO = compressor outside normal functioning; YES = compressor under normal
functioning;
— Indicates whether the compressor is on:
NO = compressor o; YES = compressor on;
— Indicates the status for compressor start-up enabling:
NO = compressor not enabled to start; YES = compressor enabled to start;
— Indicates the present of a warning status on the compressor:
NO = no warning on the compressor; YES = warning on the compressor;
— Indicates the actual temperature value read at compressor intake
— Indicates the actual temperature value read at compressor ow
— Indicates the actual temperature value read for the compressor oil
— Indicates the actual value of the minimum functioning time remaining
— Indicates the actual value of the minimum switch-o time remaining
5 ON/OFF MENU
The ON/OFF menu is used to switch the unit on or o. It also provides further infor-
mation about the current status of the machine.
 NOTE: The top-left corner of each window shows which compressor is currently
providing the displayed data (U:1,2,3 o 4); to switch between compressors (only
possible from Master unit), refer to that explained in paragraph "3.3Unit operating
status information (real time data)p.7".
5.1 SWITCHING THE UNIT ON/OFF
— Indicates to which compressor the displayed data refers (U:1 = Master; U:2 =
Slave 1; U:3 = Slave 2; U:4 = Slave 3)
— Indicates the current value selected (YES = Unit ON; NO = Unit OFF)
 Note: In case of systems with multiple compressors, the OFF command given by se-
lecting the master (U:1) turns o ALL compressors, while if a particular Slave (U:2, 3,
4) is selected only the circuit of the same will be switched o.
