threshold AH exceeded: up to three HF events are saved (HF, HF1, HF2), respectively from the most recent (HF) to the oldest (HF2), with
a signal HFn that displays the number of HF events that have occurred.
Setting the HA/HF alarm: parameter AH (high temp. threshold); Ad and Htd (Ad + Htd = HACCP alarm delay).
Displaying the details
1) When pressing the HACCP button for more than one second, the display shows the name of the fi rst parameter relating to the HA
and HF alarms;
2) Use the and
3) Once having reached the desired parameter, press set to display the value;
4) If the selected parameter is HA or HF, press the
of the last alarm HA or HF activated.
Example: y03 M07
The sequence indicates that the last HA or HF alarm was activated on 22 July 2003 at 23:57 and lasted 99 hours;
5) Pressing again returns to the list of param. relating to the HA and HF alarms; the following functions are available from inside the menu:
set
- delete the HACCP alarm, by pressing the HACCP button for more than 5 seconds (the message 'rES' indicates the alarm has
been deleted, the HACCP LED stops fl ashing, the HA and/or HF signal is reset and the monitoring of HA resumes);
- delete the HACCP alarm and the alarms saved (HAn, HA, HA1, HA2, HFn, HF, HF1, HF2), by pressing the HACCP and
buttons for more than 5 seconds (the message 'rES' indicates the alarms have been deleted, the HACCP LED stops fl ashing, the HA
and/or HF signal is reset, the HAn, HA, HA1, HA2, HFn, HF, HF1, HF2 alarms saved are cancelled and the monitoring of HA resumes);

Continuous cycle
To activate the continuous cycle function, press the
continues to operate for the entire duration, and will stop for cycle timeout or when reaching the minimum temperature established (AL
= minimum temperature alarm threshold). Setting the continuous cycle: parameter "cc" (continuous cycle duration): "cc"= 0 never active;
parameter "c6" (alarm bypass after continuous cycle): excludes or delays the low temperature alarm at the end of the continuous cycle.
Procedure for setting the default parameters
To set the default parameters on the controller, proceed as follows:
• If "Hdn" = 0: 1) disconnect power from the instrument; 2) reconnect power to the instrument holding the
"Std" appears on the display.
Note: the default values are only set for the visible parameters (C and F). For further details see the Summary table of operating parameters.
• If "Hdn" < > 0: 1) disconnect power from the instrument; 2) reconnect power to the instrument holding the
0 appears; 3) select the set of default parameters, between 0 and "Hdn", using the
until the message "Std" appears on the display.
Automatic serial address assignment
This is a special procedure that uses an application installed on a PC to simply set and manage the addresses of all the instruments (that
feature this function) connected to the CAREL network. The procedure is very simple:
1) Using the remote software, start the "Network defi nition" procedure; the application starts sending a special message ('<!ADR>') to
the CAREL network, containing the network address;
2) Pressing the button on an instrument activates the recognition of this message, which automatically sets the address to the
prg
desired value and sends a confi rmation message to the application, containing the unit code and the fi rmware revision (message 'V').
Upon recognition of the message sent by the remote application, the instrument displays the message 'Add' for 5 seconds, followed by
the value of the serial address assigned;
3) The application, once the confi rmation message has been received from one of the units, saves the information received to its
database, increments the serial address and starts sending the '<!ADR>' message again;
4) At this point, repeat the procedure from point 2 on another unit, until defi ning the addresses of the entire network.
Note: once the address has been assigned on an instrument, operation is disabled on the unit for 1 minute, for safety reasons, during
which time a different address cannot be assigned to the instrument.
