Using the
“ECS”
parameter it is possible to establish the behaviour
of the regulator at the end of the cycle.
The possible settings of the parameter are:
1
= the appliance returns to the normal regulation with the “SP t”
and “SP h” Sets without giving any signalling of end of cycle.
2
= The appliance returns to the normal regulation with the “SP t”
and “SP h” Sets signalling the “End” message on the lower display
and activating the internal buzzer and the output configured as
“End” for the time programmed in the “btEd” par..
3
= The appliance automatically goes to Stand-by state without
giving any signalling of end of cycle.
4
= The appliance automatically goes to Stand-by state signalling
the “End” message on the lower display and activating the internal
buzzer and the output configured as “End” for the time programmed
in the “btEd” par..
5 =
The appliance continues to regulate on step3 without giving any
signalling of end of cycle.
6 =
The appliance continues to regulate on step3 signalling the
“End” message on the lower display and activating the internal
buzzer and the output configured as “End” for the time programmed
in the “btEd” par..
7 =
The appliance begins to regulate again from step 2 and
continues to carry out the cycle until interrupted manually.
8 =
The appliance begins to regulate again from step 1 and
continues to carry out the cycle until interrupted manually.
4.16.1 - CONTROL
FOR APPLICATIONS ON “LEAVENING-
RETARDING / LEAVENING CABINETS”
The application envisages an initial cooling phase also known as
“blast chilling” (in which the humidity variable is not normally
controlled) for the purpose of stopping leavening and thus
preserving the product in optimum state while it awaits processing
and subsequent operations.
The second phase envisages a heating action, which is intended to
favour the leavening of the product, and the control of the humidity.
At the end of the second phase, the product is ready to be
processed and hence the cycle can be interrupted.

However, in the event that it is envisaged that the operator cannot
be present at the end of this phase, and thus cannot extract the
product, it is possible to program a third maintenance phase.
For this third phase, it is possible to program a duration in the “tS3”
par. (at the end of which a signal is given) and then make the
appliance continue to regulate with the same Set Point values (by
programming “ECS” = 6) until the user interrupts the cycle
manually.

4.16.2 - CONTROL FOR APPLICATIONS ON “CURING” CELLS
The application envisages an initial cooling phase also known as
“dripping” in which the humidity is not normally controlled) for the
purpose of rapidly cooling the product arriving from processing, and
at the same time rapidly eliminating the humidity in excess.
The second phase envisages the control of temperature and
humidity at established values and for this reason is also known as
“running”.
The third phase, on the other hand, does not typically envisage any
controlling action of the temperature and humidity variables, and for
precisely this reason, it is also called “break”.
Note:
the example shows the temperature and humidity Set Points
= OFF; however, these can obviously be set at whatever value the
user wishes.
At the end of the third phase, the cycle resumes from phase 2.
(running) and then executes phase 3. (break) again, and so on until
the manual stoppage of the cycle.
Note:
to obtain this function of repeating the cycle from phase 2., it
is necessary to set the “ECS” par. = 7

5 - TABLE OF PROGRAMMABLE PARAMETERS
Below is a description of all the parameters that the appliance can
be given; note that some of these may not be present because they
depend on the type of appliance used.
