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);
6) To return to normal operation at any time, press the prg button for 3 s, or wait for the session to expire by timeout (60 s) without pressing any button.
Continuous cycle
To activate the continuous cycle function, press the
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 prg button until the message "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 prg button until the value 0 appears;
3) select the set of default parameters, between 0 and "Hdn", using the
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 prg button on an instrument activates the recognition of this message, which automatically sets the address to the 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.
Accessing the confi guration parameters (type C)
1) Press the prg and set buttons together for more than 5 seconds, the display will show "0" (the password prompt);
2) Use the or button to display the number "22" (password to access the parameters);
3) Confi rm with the set button;
4) The display shows the fi rst modifi able "C" parameter.
Accessing the confi guration parameters (type F)
1) Press the prg button for more than 5 sec. (in the event of alarms, fi rst mute the buzzer), the display shows the fi rst modifi able "F" param.
Modifying the parameters
After having displayed the parameter, either type "C" or type "F", proceed as follows:
1) Use the or button to scroll the parameters until reaching the one to be modifi ed; when scrolling, an icon on the display comes on to show the
category the parameter belongs to;
2) Alternatively, press prg to display the "categories" menu and quickly access the family of parameters to be modifi ed;
3) Scroll the menu with the
operating parameters), accompanied by the corresponding icon on the display (if present);
4) Once having reached the desired category, press set to directly access the fi rst parameter in the chosen category (if none of these parameters are visible,
pressing set will have no effect);
5) At this point, continue to scroll the parameters or return to the "Categories" menu with the prg button;
6) Press set to display the value associated with the parameter;
7) Increase or decrease the value with the
8) Press set to temporarily save the new value and return to the display of the parameter;
9) Repeat the operations from point 1 or from point 2;
10) If the parameter has sub-parameters, press set to display the fi rst sub-parameter;
11) Press the or button to display all the sub-parameters;
12) Press set to display the associated value;
13) Increase or decrease the value with the or button respectively;
14) Press set to temporarily save the new value and return to the display of the sub-parameter code;
15) Press prg to return to the display of the parent parameter.
Saving the new values assigned to the parameters
To defi nitively save the new values of the modifi ed parameters, press the prg button for more than 5 seconds, thus exiting the parameter programming
procedure. All the modifi cations made to the parameters, and temporarily saved to the RAM can be cancelled, returning to "normal operation", by not
pressing any button for 60 seconds, and allowing the session to expire by timeout. If power is disconnected from the instrument before pressing the prg
button, all the changes made to the parameters and temporarily saved will be lost.
