C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL 6 ADJUSTMENTS 6.1 Configuration of the machine Using a wizard (Constructor menu), it is possible to configure the machine with help. The first choice involves the number of circuits (1 or 2) through the parameter PG01; in the case of a bi-circuit, the choice of condensation type, either singular or separate (PG30), becomes important as does the presence or absence of expansion (PG02).
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL 6.2 Status of the machine and of the single circuits There are multiple procedures for turning on/shutting off the unit or the single circuit: 1) By using the appropriate On/Off button (function enabled by parameter PH05) Turning On – push the ESC button for about 2 seconds: if all other enabled conditions are present, the machine will go to “ON”. Shutting Off – push the ESC button for about 2 seconds: the machine will go to “OFF”.
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL 6.3 Adjustment of the compressors Checking the suction pressure of the compressors implies the management of the compressors to reach and maintain a certain operating pressure value: according to the type of check (sideband adjustment or neutral zone adjustment) and the use or lack thereof of the inverter for a finer adjustment, four types of adjustment are considered. 6.3.
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL Gradini Rilascio Max Gradini Inserimento Aspirazione PC78 % SP SP + BP Steps will be loaded at PC78% of the proportional band; the steps will be unloaded at 100 – PC78% of the proportional band. If for example PC78 has value 60%, the steps will be loaded between 60% of the proportional band and its maximum value (100%); steps will be unloaded between 40% of the proportional band and its minimum value (0%).
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL As we can see from the figure, the adjustment foresees the setting of certain timings within which, depending on the zone, the turn-on and shutdown requests for the various steps must be adjusted to work according to established time intervals. Based on the difference between the actual suction pressure value and the reference value, the times will vary proportionally according to the values set.
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL The use of this adjustment on the principal compressor is not linked to the adjustment of the other compressors, since the two functions are independent from each other. Example: 4 compressors without inverter Example: 4 compressors with 1 inverter Steps Max steps Steps Max steps Pressure SP SP + BP Inverter 100.00 % Pressure SP SP + BP MinI Pressure SP + OFSI 6.3.
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL If the request for a shutdown remains, all the compressors are shut down, one by one, and at the end the value of the inverter is brought to zero. If the MinI parameter has been set, at every turn-on the inverter will keep that value as the starting value. If the parameter for the speedUp time has been set, at every breakaway the inverter will assume the maximum value for the seconds described by this parameter.
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL an alarm or that are in manual function mode and it is able to dynamically turn on other compressors if one or more are subject to a state of alarm. Through the PC01 parameter, the program is able to manage 4 types of rotation: FIFO, LIFO, FIFO + hours, LIFO + hours. 1) FIFO Follows the logic “First In First Out”, or in other words, the first compressor that turns on will then be the first that must shut off.

C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL 6.5 Adjustment of condensation The management of condensation foresees control through discharge pressure fans: according to the type of control (sideband control or neutral zone control) and according to the use or disuse of the inverter for a finer adjustment, four types of adjustment are considered. 6.5.
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL 6.5.2 Neutral zone adjustment This adjustment implies the definition of a neutral zone in which no decision of activation or deactivation is made, which means that there will be no requests for breakaways of any devices.
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL Inverter 100.00 % MinI Pressure SP + OFSI SP + OFSI + DI Based on the value measured by the discharge probe, the output of the regulator will assume different values. If the value measured by the probe is less than or equal to the value SP + OFSI, the output of the regulator will assume the value of 0.
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL If the parameter for the speedUp time has been set, at every breakaway, the inverter will assume the maximum value for the seconds described by this parameter. 6.5.5 Single condensation (only bi-circuit) Single condensation makes it possible to perform the ventilation process through only one circuit. For this input, it is possible to set the type of resetting (automatic or manual) through the parameters.
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL Example with 4 fans. Turn-on : F1 . F2 . Shutdown: F1 . F2 . Turn-on : F3. F4. Shutdown: F3. F4. Turn-on : F1 . F2 . F3. F4. Shutdown: F1 . F2 . F3. F4. 2) LIFO It follows the “Last In First Out” logic, which means that the last fan turned on will be the first one to be shut down. Example. Turn-on : F1 . F2 . F3 . F4 Shutdown: F4 . F3 . F2 . F1 The turn-on order will always start from the C1 compressor.
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL Protection timings These times serve to protect the fans from the various breakaways to which they are subjected. PF07 – Minimum time between turn-ons of different fans. Establishes the minimum amount of time that must pass between the turn-on of one fan and the next. If it is set, it makes it possible to avoid simultaneous breakaways. PF08 – Minimum time between shutdowns of different fans.
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL 6.7 Various management issues 6.7.1 Digital input or supervisor setpoint variation It is sometimes important to reduce the energy consumption of the compressors or the noise level of the fans (for example at night).
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL Inverters When it is an inverter that must be manually forced, the procedure is slightly different.
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL 6.7.5 Restoration of default parameters Through the “Parameter restoration” procedure, it is possible to restore all the parameters of the system to the default values. This function is simple to activate by acting on the value of the appropriate parameter PH15 present in the Map menu, accessible only when the machine is turned off; setting it to “1”, the system will automatically see to the restoration of all parameters.
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL 7 DIAGNOSTICS The application is able to manage a series of alarms related to system compressors, fans, circuits and functions. Depending on the various types of alarm, it is possible to configure their resetting (if manual or automatic), a possible delay in signal and certain actions to perform in specific circumstances. When one or more alarms are active, the alarm icon on the screens blinks.

C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL 7.3 Alarm relays The program has the possibility of managing up to three alarm relays. The activation of each of these devices is linked to the setting or lack thereof of the relative DO alarm position parameter. For activation, it is sufficient to set this value to a value that is different than zero; if the zero value is maintained, the alarm relay is not used.
C-PRO NANO RACK E C-PRO MICRO RACK APPLICATION MANUAL 8 List of the MODBUS variables It is possible to check the application through a supervisor, using the Modbus protocol. The communication occurs through a serial TTL interface, which is already integrated in the controller; we suggest using the external TTL/RS-485 interface (the interface is not supplied with the instrument). The various parameters that are exported by the application in the three versions of the application are reported below.
