• look at parameters A0, A1A and A2A
Effects:
• no effect
The instrument shows the indications above alternated with the cabinet temperature, except the indication
“E2“ (it flashes) and “E0“ (it is alternated with the indication “- - -” ) and the buzzer utters an intermittent beep.
“NEGATIVE TEMPERATURE” (49a)
Alarms must be silenced by the “
” key.
Any alarm and signalling are visualized on the display:
LED MEANING
LED compressor
if it is lit, the compressor will be turned on
if it flashes:
• the modification of the working setpoint will be running
• a compressor protection will be running (parameters C0,C1, C2 and i7)
LED defrost
if it is lit, the defrost will be running
if it flashes:
• the defrost will be required but a compressor protectionwill be running (parameters C0, C1 and
C2)
• the dripping will be running (parameter d7)
• the heating of the freezing fluid will be running (parameter dA)
LED evaporator fan
if it is lit, the evaporator fan will be turned on
if it flashes, the after dripping evaporator fan delay will berunning (parameter F3)
HACCP
HACCP LED
if on, you will have not shown all the information on theHACCP alarms
if flashing, the instrument will have stored at least one newHACCP alarm
if off, you will have shown all the information on the HACCP
alarms or you will have cancelled the list of the HACCPalarms
LED alarm
if it is lit, an alarm will be running
on/stand-by LED
if on, the device is in stand-by mode
°C
LED Celsius degree
if it is lit, the unit of measure of the temperatures will beCelsius degree (parameter P2)
°F
LED Fahrenheit degree
if it is lit, the unit of measure of the temperatures will beFahrenheit degree (parameter P2)
Door resistance LED
when the led is ON, the door resistance is connected
- - - -
the quantity for display is not available (e.g. the probe isabsent)
CODE MEANING
AH
Upper temperature alarm
Remedies:
• check the temperature joined to the alarm
• look at parameters A3, A4 and A5
Effects:
• if parameter A3 is set to 0 or if parameter P4 is set to 1 andparameter A3 is set to 1, the device
records the alarms, oncondition that the instrument has stored no alarm of thistype or on
condition that the critical value is more criticalthan the one the instrument has stored
• if parameter u1 is set to 4, the alarm output will be acti vated
AL
Lower temperature alarm
Remedies:
• check the temperature joined to the alarm
• look at parameters A0, A1 and A2
Effects:
