Adjustment of the PROBA50
The
PROBA 50
regulates and detects failures, dependant upon a number of
parameters which can be set by the installer or the user:
*
regulation characteristics
*
alarms/warnings
*
default ripening programs
*
gassing and ventilation
Normally these settings do not have to be changed daily. This is why they are
more difficult to access than e.g. the starting or stopping of a ripening program
or the changing of a setpoint.
We call changing of these settings we call 'Internal Programming'.
The
PROBA 50
can be brought into this Internal Programming mode by
simultaneously pressing the
SET
and
KEY
buttons. Start by pressing the
SET
key; then the
KEY
key.
Since most of the settings in the Interal Programming affect the regulation
characterisics of the
PROBA 50
, all controls are inactive, for as long as the
PROBA 50
is in the Internal Programming mode.
In Appendix B all parameters are shown.
The text 'iP--' appears in the display. The horizontal bar moves between the
third and fourth position. Keep both buttons pressed for two seconds and the
bar disappears.
Release the two keys.
The temperature display shows the text 'P 1'. This is the first parameter. The
value of this parameter is shown in the setpoint display.
Use the UP and DOWN keys to choose the various parameters.
By simultaneously pressing the
SET
key and the
UP
or
DOWN
key, the value
of the parameter can be changed.
End the 'Internal Programming' by pressing the
PROG
button.
If during the Internal Programming no key is pressed for 60 seconds, the
PROBA 50
stops programming and returns to it's previous state. The settings
which were changed will not be stored in the memory.
