4 INSTALLING DEFAULT VALUES
When you have checked the connections between the cards and terminals
, power up the pCO card/s*.When the machine is powered up, the
software automatically installs the default values selected by CAREL for all the chiller and driver configuration parameters.
This section tells you how to reset default values to return to the initial conditions. Therefore, this operation need not be carried out at the first
power-up.
The following procedure is used for resetting all the in-plant configuration parameters selected by CAREL:
ATTENTION! this procedure irreversibly cancels any programming done by the user
As resetting the default values is an operation that concerns each pCO* card, if there are two cards, repeat the operation for the second card. The
procedure is identical
for both cards.
These are the steps:
• simultaneously press the "menu" and "prog" keys of the LCD terminal (when pressed, both the LED above the "menu" key and the LED
above the "prog" key should light up).
• Input the password using the "arrow" keys and press Enter: in this way, you enter the "constructor" configuration :
+--------------------+
¦Constructor ¦
¦Input password ¦
¦ ¦
¦ 0000 ¦
+--------------------+
• press the up arrow key four times to rapidly reach the default values installation screen:
+--------------------+
¦Installing default ¦
¦values ¦
¦ ¦
¦Please wait... ¦
+--------------------+
• press the "enter" key to position the cursor above the letter "N", and take it to "S" with the arrow keys. The "please wait…" words appear
immediately. They disappear after a few seconds. the default values have now been fully installed.
5 SELECTING THE LANGUAGE
When the unit is powered up, a screen appears by default, where you can select the language to be used (Italian/English).
This screen stays active for 30 seconds. When this time has elapsed, the program automatically changes over to the main menu (M0 screen)
This function can be disabled. How to disable it:
1. Go to the Program (P0 screen) branch
2. Type in the correct password.
3. Press the down arrow unit you reach the screen with reference "Pa"
4. Select "N" under item "Show language screen".
In any case, you can change the language in use at any time. To do this, go to the first screen of the "I/O" key (ref.10).
