11.13.1 Automatic Cold Treatment program, ACT

Automatic Cold Treatment can only be started when all Tusda sensors are in function. If one or more
Tusda sensors fail under the Automatic Cold Treatment period, the treatment temperature is kept as
setpoint for the whole trip. When Automatic Cold Treatment is done without any sensor failure, ACT
PASSED-PRG ACTI is written in the display status texts ("9.2 Display" p. 26). If the USDA sensors
are out of range, ACT FAILED will be written.
The ACT-status will be displayed until:
• Program status set to none
• Initiated PTI
• Power off more than 48 hours
Loading cargo

Start Automatic cold treatment at 1 or 2
Termination of an active ACT can only be done by manually setting active program (P01) to none
or if the unit has been powered off for more than 48 hours. Datalog interval during ACT is default
60 min. (cannot be changed). After ACT activation, the treatment setpoint is adjustable in the legal
range.
B01 Duration of the treatment
Function:
Setting of duration in days of the Automatic Cold Treatment.
Value:
Values 1 - 45 days. The number of days to use depends on the cargo and the treatment tempera-
ture. The treatment time is counted from the validity of at least 3 USDA sensors all showing a tem-
perature below the maximum USDA temperature. If one or more USDA sensors is outrange and
returns to inrange again, the timer for the Automatic Cold Treatment will reset. ACT passed shows
that all USDA sensors have been under maximum allowed temperature in the duration time in one
period.
