F09 Serial number of controller board (Main PCB)
Function:
Shows the serial number of the controller board
Value:
-
°C and °F Temperature Scale Showing, Alternately
As long as the button is pressed, °F is shown instead of °C and PSI is shown instead of Bar.
When the button is released, °C and Bar is shown again.
Permanently change to °F/PSI is not available.
Shown pressure is relative to atmosphere pressure.
Viewing graph of Supply and Return Temperature
Press

two times.
Press
to toggle between stored set of temperatures: Setpoint tempe supply air tem-
perature, return air temperature and the other set of temperatures: USDA 1 + 2 + 3 temperatures
and cargo temperature.
Press up
or
down, , to show newer or older stored set of values from the data log.
Manual Defrost Initiation
A manual defrost is only accepted if Tevap less than (<) 15°C (59°F)
Defrosting is manually initiated by pressing the
key and holding it for 3 sec. The display shows
the
icon as an acceptance of defrost initiation.
A automatically or manually initiated defrosting may be terminated by pressing
and holding it
for 3 sec. The display will cancel the
icon.
Water-cooling Activation/Deactivation
The following only applies for Model SC-MCI40-WC
Water-cooling connecting is executed as follows:
•
The container must be connected to the water-cooling system.
•
Press
and hold it for 3 sec. The display shows the icon as an acceptance of water-cooling
operation. The condenser fan is deactivated.
Water-cooling turn-off is executed as follows:
•
Press
and hold it for 3 sec. The display turns off the
icon as an acceptance of non-op-
erating water- cooling. The condenser fan turns on automatically.
•
The container can be disconnected from the water-cooling system.
If the water supply is insufficient (the water hose is jammed, the water is not running or the
water temperature is too high), the temperature in the condenser will rise and cooling capacity
is decreasing and thereby threatening the cargo. If the condenser temperature rises above 58˚C
(136˚F), the system will automatically switch to air-cooling of condenser by turning the condenser
fan on. If the water flow is restored, the controller stops air-cooling of the condenser. If the tem
-
perature stays at the high temperature for more than 1 hour, an alarm is given. The actual setting
of water-cooling is remembered if the unit is switched off or there should be a power loss.
Water-cooling is only turned off when the set point temperature is changed or when water-cooling
is turned off manually.
