  The figure below shows all the components and optional devices of pCO dedicated to the control and regulation of refrigeration units. Main card The microprocessor-based main card is the RS422 intelligent part of the system since it carries out the regulation program. It comes complete with terminals dedicated to the connection of the main devices (eg.

  Terminal The terminal unit — managed by the microprocessor — comes complete with display, keypad and led indicators. Setting the main control parameters (set-points, differential, alarm thresholds) and performing any other operation is extremely simple. The terminal unit must be connected to the main card only when programming the instrument; after that, the two units can be disconnected.

  Connecting Keller pressure transducers This application requires two pressure transducers that must be connected to terminals B5 and B6. The first transducer will measure low pressure (suction pressure), the second transducer high pressure (delivery pressure). The fig. below shows how to connect the two KELLER transducers to the interface. Series 21 / 22 Delivery side: 0:30 bar…

  The clock card is necessary to provide a time-zones control action. In the event of power supply failure to pCO, the clock card will be powered by a lithium battery for more than one month. For connection to the relative connector (6) see page 4 above.

  (flat cables) incorrect power source to interfaces and probes FAULTY EEPROM contact qualified service personnel pCO turns Off and On repeatedly (watch-dog) or it operates some (digital and/or analogue) outputs at random. Cause: incorrect connections between interfaces and controller power cables are too close to the microprocessors of the interfaces and to the control card.

• Page 14: The Program

  The program General description pCO by Carel has been specifically designed to control and regulate refrigeration units with 1 to 3 compressors as well as 1 to 3 condensation-removal fans. The activation of the compressors depends on the value measured by the suction trnasducer and on the selected set-point; the activation of the fans depends on the delivery pressure value.

• Page 15: Software Initialization

  (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.

  1 to 3 fans and their shifts. Optional devices You can enhance the functions of the pCO controller by adding a series of optional devices (clock card, RS422 serial card) that can be enabled by simply acting on the dedicated masks.

• Page 18: Using Pco

  Using pCO Status of the system The system can be ON, OFF or in the MANUAL functioning mode. It is possible to turn ON the refrigeration unit by pressing the ON button on the keypad or — in case of network connection to a centralized computer — by means of the external command operated by the supervisor.

  On again only after all the other compressors have turned On. Compressors timer pCO also controls the working hours of the compressors. Set the required value (default 10,000 hours) in the dedicated mask. When the compressors reach the set threshold an alarm message prompting maintenance will be displayed.

  = differential) Times Most of pCO’s control actions will be operated on the basis of programmable time-delays (eg. time- delay before the activation of compressors or of certain alarms so as to ensure longer life to the compressors themselves and a well-balanced system management). pCO allows you to set the…
• Page 21
  TIME In order to set time-zones, it is necessary to provide pCO with a clock card. It is possible to program up to 4 time-zones. Should you need less than 4, it is necessary to give the unused time-zones the same values.

  This mask appears when you turn On the system. After about 5 seconds the main mask — MENU_MASK — will be displayed. You can display pCO’s masks by pressing the dedicated buttons on its front panel keypad (See ‘Keypad’ above).

  Should your system require maintenance, you can use the manual function to check the status of each single device connected to pCO (compressors and fans). In this way you can directly operate any device ignoring their previously set time-delays . In the event of off-normal conditions during the manual stage, the relative alarms will be automatically displayed.
