TECHNICAL SPECIFICATIONS
pCO
5
is a microprocessor electronic controller compatible as concerns both hardware and software with the pCO
3
family. Developed
by CAREL in compliance with the European RoHS directives, these controllers can be used for multiple applications in the air-
conditioning and refrigeration sectors. They ensure maximum versatility of application, allowing specifi c products to be developed
to customer requirements.
pCO
5
runs the control program, and comes with a set of terminals for connecting the various devices (compressors, fans,...). The
program and the parameters are saved to FLASH-MEMORY and E
2
PROM, meaning all data is retained even in the event of power
failures (without requiring a backup battery).
pCO
5
can connect to a pLAN (pCO Local Area Network) and, in addition to other pCO
5
devices, can also be connected to all other
pCO sistema controllers and all pGD family terminals. Each controller in the pLAN network can exchange any variable, either digital or
analogue, depending on the application program used. Up to 32 units can be connected (pCO controllers or terminals), for eff ective
sharing of information.
pCO
5
comes with two additional RS485 built-in serial ports compared to the other pCO controllers, one FieldBus and the other
supervisor/telemaintenance (BMS). The BMS serial line is connected, using the CAREL or Modbus
®
communication protocol over RS485,
by fi tting the pCO
5
with an optional serial card or alternatively using the built-in serial port.
Other optional cards can be used to connect a supervisor over standards other than RS485. Finally, the FieldBus serial connection, using
the optional or built-in card, provides connection to controlled fi eld devices (for example: valves, pCO
e
I/O expansions, electronic valve
external drivers,...). The pCO5 Medium size also features an optional new integrated solution: version with built-in EVD EVO valve driver,
single or twin, further expandable with the optional Ultracap module for emergency power supply to the valve driver.
Versions available:
• SMALL, MEDIUM, LARGE, EXTRALARGE (digital output with normally open contacts), valve driver;
• with or without Built-In terminal;
• with two sizes of fl ash memory;;
• with or without additional NAND FLASH memory;
• with or without solid state relay (SSR) digital outputs 24Vac/Vdc;
• with or without USB Master and Slave.
Uploading the application program
The application program can be loaded onto the fl ash memory in diff erent ways:
1. by
key:
• smart key code PCOS00AKY0;
• USB pen drive;
2. by
PC:
• 485 serial port (28.8 kbps and 115.2 kbps) using USB-485 adapter code “CVSTDUTLF0”
• USB slave
To upload via PC the “pCO Manager” program is required, available free-of-charge at the ksa.carel.com website.
P
ower supply
A class 2 safety transformer with a minimum rating of 50 VA (100 VA on the versions with built-in valve driver) and a 2.5 AT fuse
must be used in the installation to supply just one pCO
5
controller. The power supply to the pCO
5
controller and terminal (or
pCO
5
controllers and terminals) should be separated from the power supply to the other electrical devices (contactors and other
electromechanical components) inside the electrical panel. If the secondary of the transformer is earthed, make sure that the earth
wire is connected to terminal G0. This is true for all the devices connected to the pCO
5
. If more than one pCO
5
is connected, make
sure that the G and G0 references are observed (G0 must be maintained for all boards).
If using the pLAN network and for further details, see the CAREL pCO sistema manual code +0300009EN.
