Lower temperature alarm
AL
Remedies:
• check the temperature joined to the alarm
• look at parameters A0, A1 and A2
Effects:
• if parameter A0 is set to 0 or if parameter P4 is set to 1 andparameter A0 is set to 2, 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
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
• defrosting will never be activated
• if parameter u1 is set to 4, the alarm output will be activated
• if parameter u1 is set to 5 or 6, the fourth output will be deactivated
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
• if parameter u1 is set to 4, the alarm output will be activated
When the cause that has provoked the alarm disappears, the instru-ment restores the normal operation.
HACCP ALARMS
The device is capable of storing up to 2 HACCP alarms.
The device can furnish the following information:
• the critical value
• the alarm duration (from 1 minute to 99 hours and 59 minutes,partial if the alarm is ongoing).
CODE ALARM TYPE (AND CRITICAL VALUE)
minimum temperature alarm (the minimum temperatureof the cabinet or the minimum temperature detected bythe
AL
auxiliary probe during an any alarm state of this type)
maximum temperature alarm (the maximum temperatureof the cabinet or the maximum temperature detected bythe
AH
auxiliary probe during an any alarm state of this type)
Warnings:
• the device records minimum temperature alarms andmaximum temperature alarms providing the
temperatureassociated with the alarm is the cabinet temperature(parameters A0 and A3 = 0) or the
temperature measuredby the auxiliary probe, providing its function is that ofdisplay probe (parameter P4 = 1
and parameters A0 = 2and A3 = 1)
• the instrument updates the information on the alarmson condition that the critical value is more critical
thanthe one the instrument has stored or on condition thatthe information has already been displayed
• no alarms will be recorded if the device is in stand-bymode.
When the cause of the alarm is resolved, the display returns to normal.
The HACCP LED provides information relating to the status of the HACCP alarm memory.
