the change of the parameters.

SIGNALS OF THE ALARM CODES
SIGNALS OF THE ALARM CODES
The alarm codes that can be displayed by the electronic control panel are the following:
E0 Pressure switch alarm: it indicates that the unit has stopped because the pressure switch
has tripped many more times than those programmed, in a shorter time than that pro-
grammed (see the List of Parameters).
E1 Cold room probe failure alarm: it can be due to a short circuit, a cable break, a not
connected probe, the reading of a temperatue value not included in the programming
range.
E2 Evaporator probe failure alarm: it can be due to the same causes above-listed,
concerning the cold room probe.
E6 Alarm because of parameters not included in the range: control the programming of the
parameters.
PROGRAMMING OF THE P
PROGRAMMING OF THE P
If you want to change the value of some parameters programmed in the factory, you have to
act as follows:
when it is on, it indicates a state of alarm, at the same time it
could be an alarm code signal too (see the specific paragraph).
it is on when the fans are working, it blinks during the counting of
the activation delay.
when it is on, it indicates the working of the compressor;
when it blinks, it means that the starting of the compres-
sor is delayed through the counting of a timer or that it is
interrupted because of a particular condition.
it is on in case of automatic defrost, it blinks when the
defrost is manual.
it displays the cold room temperature during the
normal working, the temperature value programmed
during the change of the setpoint, the codes of the para-
meters and the corresponding values during the pro-
gramming and at last the alarm codes (see the specific
paragraph).
