Assuming that the tank is empty, Input 2 changes back to
ON, Out 3 changes to ON and Out 2 remains ON.
Assuming that the tank refills, Input 2 changes back to
OFF, Out 2 changes to OFF and pilot output number
indicates the value 3.
Assuming that the tank continues to refill, Input 1 changes
to OFF, Out 3 changes to OFF and pilot output number
indicates the value 4.
Defrost
Description of function
The defrost output changes to ON when the input
temperature is less than the minimum temperature for a
time T (T being the cumulative duration of passages below
the minimum temperature). If the temperature rises to
higher than the maximum temperature during the defrost
cycle, the defrost output reverts to OFF even if it has not
finished. This output can be triggered and stopped by
means of the corresponding inputs.
Function validation input. The
function remains inactive for as
long as this input is not activated.
Validation is implicitly active if it is
not connected.
Cumulative operating time: Time
T, in minutes, at the end of which
the function triggers defrosting (1
to 32767).
Defrost cycle: Duration of
defrosting in minutes (1 to 32767).
