HACCP FUNCTIONS

CODE
TYPE OF ALARM

minimum chamber temperature
during this alarm
AH
maximum temp alarm
maximum chamber temperature
during this alarm
id

PF

power is restored
If the duration of the power failure alarm causes a
clock error
, the
control will not provide any information regarding the alarm duration.
The control has a 48 hour capacitor backup. Any power outage
longer than 48 hours may cause a clock error.
If there is a clock
error, the time and date must be reset.
When the cause that activated the alarm event has been resolved,
the display restores normal operation except for the power failure
alarm. This requires the user to press a button to clear the alarm.
The HACCP LED provides information regarding the memory status
of the HACCP alarms. If it is on, not all of the information regarding
