14 ALARMS
14.1 Alarms
The following table shows the meaning of the alarm codes of the device.
CODE MEANING
AL
Minimum alarm temperatures (HACCP alarms)
Solutions:
- check the temperature associated to the alarm; see parameters A0, A1 and A2
Main consequences:
- if parameter A0 is set at 0, the device will store the alarm
- the alarm output will be activated (provided that parameter u1 and/or parameter u11 is set at 3)
AH
Maximum temperature alarm (HACCP alarms)
Solutions:
- check the room temperature or CPT temperature; see parameters A4 and A5
Main consequences:
- the device will memorise the alarm
- the alarm output will be activated (provided that parameter u1 and/or parameter u11 is set at 3)
id
Door micro switch input alarm (HACCP alarms)
Solutions:
- check the causes of the activation of the input; see parameters i0 and i1
Main consequences:
- the effect established with the parameter i0
- if parameter i4 is set at 1, the device will store the alarm, provided parameter i2 is not set at -1
- the alarm output will be activated (provided that parameter u1 and/or parameter u11 is set at 3)
PF
Power supply cut-off alarm (HACCP alarm)
Solutions:
- check the causes triggering the power supply cut-off; see parameters A10 and A12
- press a key to restore normal display
Main consequences: Main consequences:
- if the interruption lasts longer than the time established with parameter A10, the device will store the alarm
- the alarm output will be activated (provided that parameter u1 and/or parameter u11 is set at 3)
iA
Multifunction and Multifunction 2 input alarm
Solutions:
- check the causes of the activation of the input; see parameters i5, i6, i15 and i16
Main consequences:
- the effect established with the parameters i5 and i15
- the alarm output will be activated (provided that parameter u1 and/or parameter u11 is set at 3)
