Description of the Main Signals and Alarms

LED flashing

The activation of the corresponding function is delayed by a timer, awaiting an external signal or disabled by another procedure that is already in progress. e.g. if is a continuous cycle in progress and a defrost is called, the latter will remain pending until the end of the continuous cycle, and the corresponding LED (defrost) will flash.

E0 steady or flashing

Control probe error:

•probe not working: the probe signal is interrupted or short- circuited;

•probe not compatible with the instrument;

The alarm signal E0 is steady if it is the only active alarm (the temperature value is not displayed), while it fl ashes if other alarms are active or the second probe is displayed.

E1 flashing

Evaporator probe or food conservation probe error:

•probe not working, the probe signal is interrupted or short- circuited;

•probe not compatible with the instrument;

E2 flashing

Condenser probe or food conservation probe error:

•probe not working, the probe signal is interrupted or short- circuited;

•probe not compatible with the instrument;

IA flashing

Immediate or delayed alarm from multifunction digital input:

•check the multifunction input and parameters A4 and A7.

LO flashing

Low temperature alarm. The probe has measured a temperature lower than the set point by a value that exceeds parameter AL:

• check parameters AL, Ad and A0.

The alarm is automatically reset when the temperature returns within the set limits (see parameter AL).

HI flashing

High temperature alarm. The probe has measured a temperature higher than the set point by a value that exceeds parameter AH.

• check parameters AH, Ad and A0.

The alarm is automatically reset when the temperature returns within the set limits (see parameter AH).

EEdisplayed during operation or on power-up unit parameter reading error. See Data errors.

EF displayed during operation or on power-up operating parameter reading error. See Data errors.

Installation and Operations Manual

Ed flashing

The last defrost ended after exceeding the maximum duration rather than when reaching the end defrost set point.

•check parameters dt, dP and d4;

•check the efficiency of the defrost.

The message disappears when the next defrost ends correctly.

dF flashing

Defrost running:

•this is not an alarm signal, but rather a message that the instrument is running a defrost. Only shown if d6= 0.

CHt flashing

Dirty condenser alarm:

•check parameters A4, Ac, AE and Acd.

EtC flashing Internal clock error.

Data Error

In certain operating conditions, the instrument may detect errors in the data saved. These errors may compromise the correct operation of the instrument. If the microprocessor detects a data saving error, the display shows the message “EE”.

If the fault persists, the controller needs to be replaced. If, on the other hand, the message disappears, it can continue to be used. When “EE” error occurs frequently and/or remains for some time, the controller should be checked, as the original precision may not be guaranteed.
