Test regarding correct introduction of the probe before starting the needle probe cycle.
THE FIRST PHASE has positive result if the "temperature detected by the needle probe - temperature of the cell" differ-
ence is greater than the value established with the rc value at least 3 times out of 5 (the comparison is made every 10
sec). If this first test gives a positive result, the cycle will be activated. Only if this phase has a negative result, proceed
with a second verification phase.
THE SECOND PHASE has positive result if the "temperature detected by the needle probe - temperature of the cell" dif-
ference is greater by at least 1 °C/1 °F (with respect to the temperature of the First Phase) at least 6 times out of 8 (the
comparison is made every "rd s"). If the test gives a positive result: the cycle will be started, differently the blast chilling
cycle will be started in "timed" mode:

positive blast chill end-point temperature (temperature detected by the pin probe)
negative blast chill end-point temperature (temperature detected by the pin probe)
set-temperature positive blast chilling maximum duration
set-temperature negative blast chilling maximum duration
positive blast chilling operational setpoint (cabinet temperature)
negative blast chilling operational setpoint (cabinet temperature)
post positive blast chill storage operational setpoint (cabinet temperature)
post negative blast chill storage operational setpoint (cabinet temperature)
negative blast chilling and storage cycle enabling
"temperature detected by the pin probe - temperature of the cabinet" difference for the first
stage of the test to check correct pin probe insertion
0 = test will not be performed (neither the first nor second stages)
duration of the second stage of the test to check correct pin probe insertion

COMPRESSOR PROTECTION

operational cycle deferred compressor start-up;
deferred compressor power restoration also following a power interruption during an opera-
tional cycle
minimum elapsed time period between two consecutive compressor start-up operations
minimum compressor shut-down time
minimum compressor start-up time
storage cabinet probe error compressor shut-down duration;
see also C5 and C6 (only if C11 = 0)
positive storage cabinet probe error compressor start-up duration;
see also C4 (only if C11 = 0)
negative storage cabinet probe error compressor start-up duration;
see also C4 (only if C11 = 0)
pin probe operation during cabinet probe error
0 = pin probe
If the error occurs in "stant-by" mode
- it will not be possible to start any of the cycles
If the error occurs during timed or set temperature blast chilling operation
- the cycle will be interrupted
If the error occurs during a storage operation
- compressor activity will depend on parameters C4, C5 and C6
1 = both pin probe and cabinet probe
If the error occurs while in "stant-by" mode
- the pin probe will operate as a cabinet probe and it will only be possible to start timed cycles
If the error occurs during timed blast chilling
- the pin probe will operate as a cabinet probe and chilling will continue
If the error occurs during set-temperature blast chilling
- the pin probe will operate as both a pin probe and as a cabinet probe and chilling will continue;
it is recommended to set the i0 parameter to 2 (COMPRESSOR PROTECTION)
If the error occurs during a storage operation
- the pin probe will operate as a cabinet probe and storage will continue
