Important warnings
The CAREL product is a state-of-the-art product, whose operation is specified
in the technical documentation supplied with the product or can be downloaded,
even prior to purchase, from the website www.carel.com. – The client (builder,
developer or installer of the final equipment) assumes every responsibility
and risk relating to the phase of configuration the product in order to reach
the expected results in relation to the specific final installation and/or
equipment. The lack of such phase of study, which is requested/ indicated in
the user manual, can cause the final product to malfunction of which CAREL can
not be held responsible. The final client must use the product only in the
manner described in the documentation related to the product itself. The
liability of CAREL in relation to its own product is regulated by CAREL’s
general contract conditions edited on the website
www.carel.com and/or by specific agreements with
clients.
WARNING: separate as much as possible the probe and digital input signal
cables from the cables carrying inductive loads and power cables to avoid
possible electromagnetic disturbance. Never run power cables (including the
electrical panel wiring) and signal cables in the same conduits.
Disposal of the product: The appliance (or the product) must be disposed of
separately in accordance with the local waste disposal legislation in force.
General characteristics
μPCII is a microprocessor-based electronic controller developed by CAREL for
many applications in the air-conditioning, heating and refrigeration sectors
and solution for HVAC/R sector. It ensures absolute versatility, allowing
specific solutions to be created on customer request. Using 1tool software
developed by Carel for programmable controller it is assured maximum
programming flexibility suitable for each application. µPCII controls inputs
outputs logic, the pGD user interface and others devices communication thanks
to three serial ports built in. The universal channel (called on the drawing
U) could be configured by application software to connect active and passive
probes, free voltage digital inputs, analog outputs and PWM outputs. This
technology increase the configurability of input output lines and flexibility
of the product for different applications. The 1TOOL software installable on
PC, for the creation and customization of application software, simulation,
monitoring and definition of pLAN networks, allows us to develop new
applications quickly. The loading of the application software is controlled
using the program pCO Manager, free available on the site
http://ksa.carel.com.
