ALL Minimum temperature alarm (it is used only during the holding phase)
: (1÷50°C/1°F)
When the “SET-ALL” temperature is reached the alarm is enabled, (possibly after the “ALd”
delay time).
-
ALd Temperature alarm delay (it is used only during the holding phase)
: (0÷255 min) time
interval
-
between the detection of an alarm condition and alarm signaling.
-
EdA Temperature alarm delay at the end of defrost (it is used only during the holding
phase): (
0 ÷ 255 min) Time interval between the detection of the temperature alarm condition at
the end of defrost and alarm signaling.
-
tbA Silencing alarm relay:
(Yes= silencing buzzer and alarm relay, no= only buzzer silencing).

g. How a cycle is done
1. Every programmable cycle Cy1, Cy2, Cy3 or Cy4 can be divided into up to 3 phases usually called:
Hard chill
Soft chill
Freezing cycle
2. For each phase there are 3 parameters.
iS1, (iS 2, iS 3):
Set point related to the insert probes that stops the current phase.
rS1, (rS2, rS3):
set point of the room temperature for each phase.
Pd1, (Pd2, Pd3):
the maximum duration time for each phase.
Hds :
set point of the hold phase at the end of the whole cycle.
There are also 3 parameters:
First one concerning the cycle way of doing the cycle: by temperature or by time, the other two are related to
defrost. These are
dbC =
defrost before cycle,
dbH =
defrost before holding (at the end of the cycle).
Configurable cycle parameters
-
cyS Cycle setting: tEP =
by temperature. The cycle is done according to the
rEM
parameter;
tiM:
timed cycle, based on the Pd1, Pd2, Pd3 parameters.
-
dbc (
yes/no)
Defrost before the cycle
-
iS1 (
-50÷50°C;1°C/1°F)
Insert Probe Set point
: when the temperature measured by the three insert
probes reaches this value the first phase is ended.
-
rS1
(-50÷50°C; 1°C/1°F) Room probe Set point for the first phase: it prevents temperature from
reaching a too low value during the hard cycle.
-
Pd1 (
OFF÷4.0h;10 min)
Maximum time for first phase
-
iS2 (
-50÷50°C; 1°C/1°F)
Insert probe set point
when the temperature measured by the three insert
probes reaches this value the second phase is ended.
