Cabinet probe error
Remedies:
• look at parameter P0
Pr1
• check the integrity of the probe
• check the connection instrument-probe
• check the cabinet temperature
Effects:
• the compressor activity will depend on parameters C4 and C5
Evaporator probe error
Pr2
Remedies:
• look at parameter P0
• check the integrity of the probe
• check the connection instrument-probe
• check the cabinet temperature
Effects:
• if parameter P3 has value 1, the defrost will last the timeyou will have set with parameter d3
• if parameter P3 has value 1 and parameter d8 has value 2,the instrument will work as if parameter d8 had value 0
• if parameter F0 has value 3 or 4, the instrument will workas if the parameter had value 2
When the cause that has provoked the alarm disappears, the instru-ment restores the normal operation.
Alarms must be silenced by the "
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 LED
if on, you will have not shown all the information on theHACCP alarms
HACCP
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
LED Celsius degree
°C
if it is lit, the unit of measure of the temperatures will beCelsius degree (parameter P2)
LED Fahrenheit degree
°F
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
Upper temperature alarm
AH
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
"NEGATIVE TEMPERATURE -20/-10°C; -22/-15°C" (48c)
