QUICK-COOLING/FREEZING FOR TIME

NOTE CODE PARAMETER DESCRIPTION MIN. MAX. U.M. STAND.

quick-cooling/freezing for time length 0 999 min. 90

NOTES

(1) = configuration parameters present on Level 1.

(2) = reading parameter (it can not be changed).

(3) = it establishes the time between the start of an automatic or manual defrost and the start of the following automatic one and, during

a cycle/phase of cold-storing, the time between the start of the cycle/phase of cold-storing and the start of the first automatic defrost;

if the parameter has value 0 the automatic defrost will never be activated, excepting the parameter d4.

(4) = it establishes the kind of defrost that the instrument must manage, as indicated:

0=resistances (during the defrost compressor output deactivated and defrost output activated),

1=hot gas (during the defrost compressor and defrost outputs activated),

2=air (during the defrost evaporator fans and defrost outputs activated).

(5) = it establishes if to subjugate the compressor output to the disabling time established with the parameters C0, C1 and C2 or to clear

this times when a defrost is requested, as indicated:

0=the disabling time are observed,

1=the disabling time are cleared.

(6) = it establishes the measure unit for the parameters d0, d3, d7 and F5, as indicated:

0=the measure unit for the parameter d0 is hours, the measure unit for the parameters d3, d7 and F5 is minutes,

1=the measure unit for the parameter d0 is minutes, the measure unit for the parameters d3, d7 and F5 is seconds.

(7) = it establishes the output activity, as indicated:

0=the output activity depends from the temperature read by the evaporator probe and from the parameters F1 and F2, excepting

the parameters d7, F3, F4 and F5,

1=the output is continuously activated, excepting the parameters d7, F3, F4 and F5.

(8) = set to 0 this parameter if the digital inputs are not used.

(9) = if the parameter has value 0 the temperature alarm is disabled.
