Page 16: Suction Controls
The main control output is the first to be on and the last to be switched off. On the other hand, the auxiliary output is generally used to activate or deactivate an unloader valve to regulate the capacity of the compressor. RCK-602 plus has three activation... -
Page 17: Compressors With Proportional Modulation (Frequency Inverter)
When only digital outputs are associated to the Linear control mode, it commands the activation and deactivation of each compressor sequentially and with pressure intervals of the same magnitude (step). RCK-602 plus uses a pressure setpoint and hysteresis value for compressor suction control. If the compressors have unloader valves (auxiliary outputs), the drive logic is PPUU (Main first and then the unloader valves). -
Page 18: Linear Mode Using A Proportional Compressor (Inverter) In Conjunction With Compressors Associated With Digital Outputs
14.SUCTION CONTROLS Example: Linear control associated with digital outputs of compressors with unloaders Compressors with unloaders. When compressors with unloaders are used in linear mode, all the main compressor outputs are activated first and then the unloaders are used. 1.2.x.23 Modulation of compressor 2:0 I50 I 100 1.2.x.2 Control mode: Linear 1.2.x.24 Modulation of compressor 3: 0 I 33 I 66 I 100 1.2.x.3 Setpoint: 25 psi... -
Page 19: Linear Mode Associated With A Frequency Inverter
14.4.1.3 Linear Mode associated with a frequency inverter A 0-10 V analog output is used to control a frequency inverter linked to one or more fans. In this case RCK-602 plus considers the setpoint and hysteresis values of the analog output. The modulation of the analog output occurs when the difference between the measured pressure/temperature and the setpoint is equal to or greater than the minimum analog output value up to the maximum analog output value. -
Page 20: Rotation Mode
14.SUCTION CONTROLS Activation step = Hysteresis of digital outputs / Number of compressors = 12.0 / 3 = 4.0 psi Disregarding the dead band effect, the pressure values for the activation of compressors 1, 2 and 3 would be 34.0, 38.0 and 42.0 psi, respectively. Considering the dead band effect, no compressor must be activated until the pressure exceeds 45.0 psi, so compressors 1 to 3 will only be activated when the pressure exceeds this value. -
Page 21: Progressive Algorithm Mode
14.SUCTION CONTROLS 14.4.5 Progressive algorithm mode: The Progressive Algorithm control mode is ideal for systems that use compressors with different capacities for suction, which considers the capacity of each compressor to meet the system's thermal demand and seeks to optimize the use of unloader valves and minimize the number of compressors starts and stops. -
Page 22: Discharge Controls
Discharges can be controlled by monitoring pressure or temperature. The control type is adjusted according to the variable being used. Pressure: If the control type (1.3.x.3) is set for control by pressure, RCK-602 plus uses the pressure-related parameters 1.3.x.4 to 1.3.x.11, 1.3.x.20 and 1.3.x.21. -

15.DISCHARGE CONTROLS 15.2.1.3 Fan with inverter modulation: A fan with frequency inverter is controlled using an analog output (0-10 V). Only fan 01 of each discharge can be set as inverter. During operation, the inverter-modulated fan is the first to be activated and the last to be deactivated. Configuration example: In item 1.3.x.25 , set “Fan 01 Modulation”... -
Page 24: Auxiliary Functions
16.AUXILIARY FUNCTIONS RCK-602 plus allows configuring some additional functions to control the Rack system. The Pump Down logic and liquid injection thermostat logic apply to the suctions. The Pump Down function allows switching off all compressors of a group with refrigerant collection. The liquid injection thermostat, on the other hand, allows controlling the operating temperature of the compressors by means of a liquid injection valve. -
Page 25: Liquid Injection Thermostats
16.AUXILIARY FUNCTIONS 16.2 Liquid injection thermostats: The liquid injection thermostats can be used for compressor cooling. It is possible to associate one thermostat for each compressor. To enable a thermostat, it is necessary to configure a setpoint for the compressor working temperature, a hysteresis, a temperature sensor, and a digital output. The output is activated when the compressor temperature is higher than the setpoint plus the hysteresis and will be switched off when the temperature is lower than the setpoint. -
Page 26: Cyclical Timer Mode
If all four parameters are set correctly, the control will be done by both modes (temperature differential and temperature limits) and whenever at least RCK-602 plus one of the two modes has an activation condition, activates the adiabatic cooling control output. In this case, the output is activated when the dry bulb sensor temperature exceeds the Activation temperature and is deactivated when the temperature is lower than the Deactivation temperature;... -

17.ALARMS RCK-602 plus features an alarm system in which alarms can be configured for protection or for display only. All alarm configurations are linked to the suction and discharge pressostat In the event of an alarm, an audible warning will sound and remain active until one of the following conditions occurs: - The alarm condition no longer exists and the alarm is not in manual reset condition. -
Page 29: Automatic Resets
If the number of attempts is set to the minimum value “Off ”, the reset will be manual only. If the number of attempts is set to the maximum value “Always”, RCK-602 plus will not limit the number of reset attempts, respecting only the times. -
