7.2.1.5.4.3 Idle setup mode (menu 1.5.3.3)
The idle setup mode is entered when the <CHANGE> key is pressed in
menu 1.5.3
.
In menus 1.5.2.1 – 1.5.2.13 the system has been setup for a specific discharge operation.
Next the system goes through the calibration flush sequence, cleaning and calibrating the system
and reading it for discharging ballast water.
When a discharge operation has been carried out and for instance ballast another tank is to be
discharged next with water with another type of contamination, it will be very inconvenient to go
back to the previous setup menu.
Therefore a second, but limited, setup is available to change specific parameters without the need
to go through the flush sequence again.
The following settings in the idle setup menu (
menu 1.5.3.3.1 - 1.5.3.3.9
) can be set:
Menu Description Range Remark
1.5.3.3.1 Sample point 1…6 The value to be entered is the number of the sample point
from which a sample is taken.
1.5.3.3.2
Discharge mode clean ballast / dirty ballast The value entered sets the mode in which the MCU
operates.
In dirty ballast mode the ship's speed and overboard
discharge flow input parameters are computed and the oil
concentration is calculated.
In clean ballast mode the ship's speed and overboard
discharge flow input parameters are not computed and only
the oil content is registered.
The maximum oil content permissible in this mode is
15ppm*.
1.5.3.3.3 Discharge alarm 0…30 l/NM The value to be entered is the maximum quantity to be
discharged per nautical mile (normally 30 l/nm).
1.5.3.3.4 Speed indication automatic / 0…40 knots Speed indication can be Automatic(A) or Manual(M).
Automatic can be selected by pushing the - button.
Manual can be selected by pushing the + button.
1.5.3.3.5 Flowrate indication automatic / 0…32,000 m³/h Flow rate can be Automatic(A) or Manual(M).
Automatic selection must be made in IDLE SETUP/SETUP
menu.
Manual selection by entering a value in the SAMPLE SETUP
menu
1.5.3.3.6 Oil type 0…31 The type of contamination as mentioned in section 3.6
1.5.3.3.7 Concentration alarm 0…1,000 ppm The value to be entered is the maximum concentration to be
discharged.
1.5.3.3.8 Oil concentration indication automatic / 0…1,000 ppm Oil concentration can be Automatic(A) or Manual(M).
Automatic selection must be made in IDLE SETUP/SETUP
menu.
Manual selection by entering a value in the SAMPLE SETUP
menu.
1.5.3.3.9 Display contrast 710…790 Display contrast can be set between 710 and 790.
Default is 750.
* In special occasions a maximum oil content up to 50 ppm can be entered.
