SURVEY OF MESSAGE TEXTS
MINIMUM
At starting up of compressor it will always adjust up to its minimum capacity (set point C/F5) and
"MINIMUM" will appear in the display.
RUN
When the compressor is exceeding minimum capacity (mentioned above) the message line will
change from "MINIMUM" into "RUN". This message will always be shown in the display during
operation unless another message text appears overwriting "RUN".
RESTART
If attempts are made to start the compressor before the restart time (set point A/F2) has expired
"RESTART" will appear in the display and the compressor does not start. Can be reset with "Clear
alarm", <F6>.
PUMP
This text will appear in the display if the oil pump is only running. Could for instance be during
starting up or at manual operation.
START
The text is shown in the picture during start-up. That is to say, from the moment the start signal is
given to the compressor motor until feedback from the starter is received. Then MINIMUM is shown.
V+ or V-
If the optimum Vi is higher than that on which the compressor runs, V+ will be shown. At the moment
the signal to the solenoid valve arrives V+ flashes twice. If a constant signal is sent to the solenoid
valve, V+ will continue to flash.
Correspondingly, V- indicates that the optimum Vi ratio is less than that on which the compressor
runs.
C+ or C-
If the suction pressure or brine temperature is over the actual setpoint, C+ will be shown in the
display, because the capacity should be increased. At the moment the signal to the solenoid valve
arrives, C+ will flash twice. If a constant signal is sent to the solenoid valve, C+ will continue to flash.
Correspondingly, C- indicates that the compressor is adjusting the capacity downwards.
KN
The suction pressure/brine temperature is within the dead band zone (set point B/F2) and there will be
no capacity adjustment.
