Integrated start capacitor. - **Integrated diagnostics.** Detection for voltage dips and interruptions. Detection of welded relay contacts. - **Adjusts to load requirements.** The built-in HP function ensures that the compressor starts in < 1 second even under high pressure difference during start. - **Guided model selection.** Easy to use online selection tool to select the appropriate soft starter model depending on the compressor brand/model. http://gavazziautomation.com/nsc/HQ/EN/soft_starters. - **Reduces light flicker.** RSBS reduces the compressor start current by >50% to reduce light flickering. ## **Description** The **RSBS....V23C..** is a single phase soft starter for 1 phase compressors up to 32 Arms. The **RSBS** can limit inrush currents to 45 AACrms (under balanced conditions) and has a maximum ramp-up time of 600 ms. A special function (HP function) allows the **RSBS** to start compressors, even when pressures are not balanced, by allowing a maximum current of 80 AACrms. Following the ramp-up, the semiconductors will be bypassed by the internal electromechanical relay. The **RSBS** is rated for a maximum of 10 starts per hour (evenly distributed). ## **Applications** - Scroll compressors, piston compressors ## **Main features** - Limitation of compressor starting current - Ramp-up time optimised to 600 ms - Anti-short cycling function with built-in delay between starts - Voltage dips/interruptions detection during bypass state **1** 13/02/2024 RSBS DS ENG Carlo Gavazzi Ltd. **RSBS** ## **Order code** > **RSBS 23 32 A2 V23 HP** ~~Ce~~ |**Code**|**Option**|**Description**|**Notes**| |---|---|---|---| |**R**|**-**|Soft starter|| |**S**|**-**||| |**B**|**-**|Compressor soft starter|| |**S**|**-**|Singlephase control|| |**23**|**-**|230 VAC|Rated operational voltage| |**32**|**-**|32 Arms|Rated operational current| |**A2**|**-**|230 VAC|Rated control voltage| |**V**|**-**|Options|| |**2**|**-**|Auxiliaryrelayoutput|Alarm status indication| |**3**|**-**|Thirdgeneration|| ||**C24**|Internal start capacitor: 200 – 240μF|| ||**C17**|Internal start capacitor: 145 – 175μF|| ||**C10**|Internal start capacitor: 100 – 140μF|| ||**C00**|External start capacitor|| |**HP**|**-**|Control algorithm for highpressure starts|See caution notes| - The internal relays may be in an undefined state due to shocks during transportation. In case both relays are latched in the ON state, there will be a direct on line start of the compressor, even without a control signal. - To avoid direct on line start, the user should do an initial power up with no load connected for a period of ≥ 3 seconds. - Short circuit and overload protection are not provided with the RSBS and must be installed separately. - The RSBS soft starter is not to be used as a safety device. The RSBS, on its own, cannot guarantee any safety and therefore other components need to be used to ensure that the system operates safely. - Repeated starts under unbalanced pressure (resulting in HP starts) will reduce the lifetime of the RSBS. ## **Selection guide** |**Start capacitor size**|**Part number**| |---|---| |**200 – 240μF**|RSBS2332A2V23C24HP| |**100 – 140μF**|RSBS2332A2V23C10HP| |**145 – 175μF**|RSBS2332A2V23C17HP| |**External**|RSBS2332A2V23C00HP| For proper model selection refer to our online soft starter selector tool: http://www.gavazziautomation.com/nsc/HQ/EN/soft_starters **2** 13/02/2024 RSBS DS ENG Carlo Gavazzi Ltd. ## **RSBS** ## **Selection guide** **Category Compressor maximum operating current (IMAX) Model selection** 2.5 - 16 Arms RSBS2332A2V23C10HP Compressors 16 - 32 Arms RSBS2332A2V23C24HP Note: For compressors with IMAX ≥ 25 Arms that start with unequalised pressures (> 5 bar) the model RSBS2332A2V23C00HP is recommended. **Further reading** > ~~es~~ **Information Where to find it** RSBS instruction http://cga.pub/?a1f658 manual oc-=: Troubleshooting http://cga.pub/?686d1f guide ~~ee.~~ io oe 3D (.dwg) - http://cga.pub/?ada314 Le[=] Elite] CAD drawings 2D (.dwg) - http://cga.pub/?e0d224 ~~OS~~ lel Step (.stp) - http://cga.pub/?f889f6 ~~a~~ **CARLO GAVAZZI compatible components** > **Purpose Component name/code Notes** ~~ee~~ External start capacitor kit STARTCAP-200UF-SMA For RSBS2332A2V23C00HP models Note: Use a start capacitor with rated voltage of 330 VAC or higher.

Typical applications include scroll and piston compressors. ## **Current limit algorithm** The RSBS soft starter series works on a current limit algorithm. When control signal is applied via the On terminal, the RSBS start the ramp-up sequence. The compressor start current is limited to 45 Arms. Once the compressor reaches full speed, the RSBS automatically detects this condition and switches on the bypass relay to reduce heat dissipation within the electrical panel. The RSBS will optimise the motor start time to around 600 ms (See Fig. 1). If the motor does not reach full speed within a maximum of 1 second, the RSBS will trigger the excess ramp-up time alarm (5 flashes) to protect the internal relay from switching a too high current that would reduce the relay lifetime. The alarm will self-recover after 5 minutes. ## **High pressure (HP) function** During the ramp-up sequence, the RSBS will check if the motor is rotating. If the RSBS finds that the motor is in locked rotor condition, it will trigger the HP function after ~ 250 ms (See Fig. 2). During the HP sequence, the RSBS will gradually increase the current limit setpoint up to a maximum of 80 Arms. This mode of operation is required when the starting pressures are not balanced or where voltage supply is very weak. Note: Starts under unbalanced pressure conditions can reduce the lifetime of the RSBS due to the higher current flowing through the components. Allow enough time between starts to ensure that starting pressures difference is kept to a minimum. **==> picture [412 x 104] intentionally omitted <==** **----- Start of picture text -----**

If supply on RSBS is removed before the recovery period (6 mins) has elapsed, when supply is restored, the remaining delay will continue until the remaining recovery time (before supply removal) is over. ## **Alarms** The RSBS includes a number of diagnostics and protection features each of which is signalled through a flashing sequence on the red LED. Note: In case there is a fault in the internal power supply (PSU) of the RSBS, the green LED (and not the red LED) will start flashing. In this condition, the relay contact will not change state. ## **Flashing sequence** Every alarm that the RSBS will trigger will be signalled via a specific flashing sequence on the red LED. The specific alarm will flash with a period of 2 s ON, 2 s OFF. ## **Flashing sequence during recovery from alarm** When the alarm can self-recover, the flashing sequence of the red LED will be interleaved with a 6 s ON-OFF-ON flashing sequence and then the flashing sequence will repeat (see diagram below). **12** 13/02/2024 RSBS DS ENG Carlo Gavazzi Ltd. **RSBS** ## **Flashing sequence when user intervention is required** In the case where user intervention is required to perform a hard reset, the flashing sequence of the alarm will be followed by a 6 s OFF period followed by the flashing sequence.
