2.1.11 Changing the program clock
During the course of a ripening program, it is possible to change the
program clock of the
PROBA110 . The length of a program can be made
shorter by stepping forward or longer by stepping back.
Of course the key switch should be in the PE position. The PROG LED lights
to indicate that a program is running.
Press the SET key and next the SENS/TIME key. The LED above the key
starts flashing to indicate that this function is active.
The upper display shows the program clock, which shows how long the
program has run in the current day. In this example 15 hours and 24
minutes.
The lower display shows number of the present day.
With the UP and DOWN keys the clock can be changed.
Press the SET key to accept the new time.
Rotate the key switch to the ON position and remove the key from the
switch.
Please note:
It is not possible to step from a program into STANDBY . This is only
possible by pressing the STANDBY key.
Neither is it possible to step from a program into day 0 or from day 0 into day
1 of a program.
When changing the program clock, gasification and ventilation periods can
also be skipped.
2.1.12 Switching sensors on/off
The user has the possibility to switch present sensors on or off.
Sensors which are switched on will be used for the regulation, sensors which
are switched off not. This is useful if a sensor is not to be used or a sensor
which does not measure correctly or a broken relative humidity sensor can
be switched off. The illuminated LED's in the
SENS row indicate which
temperature sensors are active.
Make sure the key switch is in the PE position.
Press the SENS key. The LED above the key starts flashing indicating that
this function is active.
