2 Smart Relays - SRW01 Series The SRW01 is a low-voltae electric motor manaement system with state-of-the-art technoloy and network communication capabilities. Additionally, its modular concept allows to be used in various applications. Versatility The SRW01 supports the followin communication networks protocols: DeviceNet, Modbus-RTU, and ProfiBus-DP. The communication modules can be easily exchaned due to plu-and-play capabilities. A HMI also can be used for quick system monitorin and relay parameterization. Additionally, the SRW01 provides a USB port for relay monitorin and prorammin throuh PC when usin WLP software. The SRW01 includes a thermal memory circuit in order to maintain a motor thermal imae, even if power supply is removed. Flexibility The SRW01 modular concept allows easy functionality expansions. The control unit can also be mechanically assembled with the control measurement unit or separately (up to 2 meters), allowin system interation versatility. The relay offers pre-prorammed operatin modes that perform various types of standard startin or monitorin conditions. Its friendly parameterization mode allows users to proram the relay accordin to their needs ASK-4WEG

3 Modular Desin The SRW01 incorporates a main control unit (SRW01-UC) and a current measurement unit (SRW01-UMC) to provide flexible assembly options. The SRW01-UC and SRW01-UMC are electrically connected usin the SRW01-CB flat cable. The interface with the relay may be performed in three ways: Via Fieldbus (ModBus, DeviceNet, Profibus) Via Keypad (SRW01-IHM) Via software WLP (USB) Throuh Fieldbus, the user can operate, monitor, and confiure the SRW01 remotely, via PLC or supervisory system.

4 Characteristics The SRW01 relay has a Vac / Vdc supply voltae rane, with I0 either 24 Vdc or 110 Vac makin system interation flexible. The reduced size of SRW01-UC, with a width of 45mm and heiht of 100mm, make it a compact product Reset ProfiBus - DP network connection Mini USB port Connection for HMI and accessories ModBus, DeviceNet or ProfiBus - DP connection Communication module The SRW01-UC control unit provides LED indicators for input and output activations, status, operation mode, power supply status, failure and alarm status. The mountin of the control unit can be done either by 35mm DIN rail or onto back panel mountin. Communication protocols: DeviceNet, Modbus, and Profibus are defined usin proper protocol installed in the communication drawer. The plu and play concept automatically reconizes and confiures the SRW01 for safe operation avoidin manual error connections ASK-4WEG

6 Functions The SRW01 protection, monitorin and operatin functions enhance system protection, reliability, and precision. The operatin modes are auto-adjustable, meanin that the user selects the operatin mode and the relay search for proper parameters automatically. This feature ensures quick and safe parameterization. All operatin modes allow motor monitorin. Its friendly parameterization mode allows users to access all diital inputs and outputs, thus increasin flexibility to cover many applications. Protection Operatin Modes Overload protection (adjustable trippin class 5-45). Thermal protection via PTC. Phase loss protection. Protection aainst current umbalance between phases. Protection aainst overcurrent and locked rotor. Protection aainst undercurrent. Internal round fault protection. Protection aainst out of rane frequency. Monitorin Diital input and output activation. RMS current of each phase and averae in amperes or % of In adjusted current. Motor frequency Number of activation per failute type. Number of start ups. Motor runnin hours. Relay runnin hours. Phase umbalance levels. Internal round fault current. Transparent operation - Diital input and output can be confiured accordin to application needs. Operation as overload relay similar to an overload relay. Direct starter - direct-on-line starter for sinle and three phase motors Reversin starter - reversin starter for three phase motors. Star-Delta starter - star-delta starter for three phase motors. Dahlander starter- starter for Dahlander three phase motors. Two windins starter - starter for two windins three phase motors. PLC mode similar to the runnin of a PLC. In this mode the SRW01 UMC is not used ASK-4WEG

7 WLP Software The WLP is the SRW01 confiuration software for Windows environment with user friendly interface that enables system parameterization, prorammi, controllin and monitorin. The WLP software enables the user to confiure the relay, edit parameters and proram in LADDER. Throuh the WLP confiuration assistants the user has a uided routine that enables relay confiuration. When necessary, the relay can be prorammed in LADDER usin mathematical and control blocks. The LADDER proram has a 64 Kbyte memory and can use the relay diital inputs and outputs. Communication between software and relay can be performed throuh USB port or ModBus network. The WLP software is free and supplied with the product. It can be also obtained from the website Confiuration Assistants These routines have been especially created to assist relay confiuration. They help the user to confiure the relay in an easy self explanatory manner. Confiuration Assistant: Control Confiuration. Monitorin Dialoues These dialoues have been especially created to monitor the relay. They monitor exclusive relay information. Monitorin dialoues: Dianostic. Data is subject to chane without notice.
