C-PRO MEGA RACK & C-PRO GIGA RACK APPLICATION MANUAL 6.4.11 Refrigeration power incrementing at high pressures In order to avoid tripping the condensation high pressure pressure-switch, with consequent blocking of cold production, it is possible to reduce the refrigeration power and consequently the power to be exchanged by the condenser, thus reducing condensation pressure.
C-PRO MEGA RACK & C-PRO GIGA RACK APPLICATION MANUAL 6.5 Condensation regulation Condensation management envisages control of the supply pressure using the fans: depending on the type of control (side band or neutral zone) and the use, or otherwise, of inverters for fine adjustment, four types of regulation are envisaged. 6.5.
C-PRO MEGA RACK & C-PRO GIGA RACK APPLICATION MANUAL ⋅ Side band suction SetPoint (SP) Outwith said neutral zone, device on or off requests for the configured fans will follow this logic: ⋅ Switch on: when the supply pressure exceeds the setPoint + Neutral Zone threshold ⋅ Switch off: when the pressure drops below the setPoint In this type of regulation, the neutral zone is displaced to the right of the setPoint.
C-PRO MEGA RACK & C-PRO GIGA RACK APPLICATION MANUAL If the value measured by the probe is between the value of SP + OFSI and the value of SP + OFSI + ID, the regulator output will assume a value proportional to the supply probe value. In the case where the supply probe assumes a value greater than or equal to the value of SP + OFSI + ID, the inverter output will assume the maximum value.
C-PRO MEGA RACK & C-PRO GIGA RACK APPLICATION MANUAL ⋅ when the inverter reaches the maximum value one of the other fans is requested. In the case where the on zone remains ongoing one or all the fans are switched on and the inverter value remains at maximum. In the off zone: ⋅ as soon as requested, the inverter output is adjusted, according to TI, to the minimum value.
C-PRO MEGA RACK & C-PRO GIGA RACK APPLICATION MANUAL 6.6 Fan management The program is capable of managing up to a maximum of 12 fans (8 if using C-PRO MEGA) divided according to circuit. A digital input for safety devices and a digital output for switching on/off may be associated with each fan. The number of fans that can be used is further limited by the number of compressors (and stepped compressors), i.e. the number of free digital outputs remaining after the compressors have been configured.
C-PRO MEGA RACK & C-PRO GIGA RACK APPLICATION MANUAL 4. On: the fan is on. In this state, the user interface displays the message “ON”. 5. Awaiting switch on: the fan is about to be switched on, and is currently waiting protective device waiting times. In this state, the user interface flashes the message “WON”. 6. Alarm: the fan is off and in the alarm state. In this state, the user interface displays the message “ALL”. 7. Manual: the fan is in manual operational mode.
C-PRO MEGA RACK & C-PRO GIGA RACK APPLICATION MANUAL 2) LIFO This follows “Last In First Out” logic, i.e. the last fan switched on will be the first to be switched off. Example. Switch on : F1 . F2 . F3 . F4 … . F12 Switch off : F12 . … F4 . F3 . F2 . F1 3) FIFO + time of operation This type of rotation functions by considering the number of operating hours for each fan. Startup will switch on the fan with the least operating hours, while shut down will switch off the fan with the most operating hours.
C-PRO MEGA RACK & C-PRO GIGA RACK APPLICATION MANUAL Neutral zone timings These parameters are used to time the switching on and off requests for the various condensation devices. Minimum switch on/off request time - TOn/Off For these parameters, please refer to the description given in section 2.5.2. Protective device timings These times are required to protect the fans from the various startup operations to which they are subjected. TOnOther – Minimum different fan switch on time (PF07).
