Software Initialization - Carel pCO Manual

Software Initialization

Initializing the software means to set a series of important parameters such as:
- number of compressors and fans
- control parameters (set-points, times, alarm thresholds, etc.)
All set data are permanently stored and retrieved any time pCO is turned ON. The very first time
pCO is turned ON, we recommend cancelling the original data since they might be unsuitable for
your application requirements and then loading the factory-set parameters so as to make the
initialization procedure fast and easy.
Follow these indications:
- Turn pCO ON. After a few seconds the main mask - MENU MASK - appears on the display.
When starting pCO the very first time, ignore any alarms since they probably result from
incorrect data.
- Press MENU + PRG simultaneously. Now you have to digit the password, necessary to
prevent unauthorized access to the operational parameters (configuration section).
- Digit the correct password. After that the configuration masks can be accessed. Use the UP
& DOWN buttons to reach the CONF_MACHINE7 mask allowing you to delete the back-up
memory and automatically set the entire range of factory-set values.
If some standard values do not suit your application requirements, just change them by entering the
dedicated selection mask/s.
- ¹ MANUFACTURER password: "1234" . We recommend keeping the password secret so as
to prevent unauthorised access to the operational parameters. The Manufacturer password
can be used when performing preliminary operations as well as any time you do not manage
to gain access to the configuration mask by the SERVICE password in the
CONF_MACHINE6 mask.
