Motor Soft Starter: The HPS2DB series intelligent economic soft startis a highly sophisticated and reliable starter designed for use with standard three-phase, three-wire, squirrel cage induction motors. It provides the best method of reducing current and torque during motor starting. The optional RS 485 Communication with MODBUS protocol enables full control (Start, Stop, Dual Adjust, command, etc.) and supervision. Up to 32 starters can be connected on a shield twisted pair to a host computer. Starting & Stopping : Prior to Installation Check that Motor's Full Load Ampere is lower than or equal to the starters Full Load Current and that Main and Control voltages are as indicated on the front panel. Mounting The starter must be mounted vertically, allow sufficient space above and below the starter for suitable airflow. Motor Starter It is recommended to mount the starter directly on the rear metal plate for better heat dissipation. Do not mount the starter near heat sources. Protect the starter from dust and corrosive atmospheres. Temp. Range and Heat Dissipation The starter is rated to operate over a temperature range of -10ºC (14ºF) to + 50ºC (122ºF). Relative noncondensed humidity inside the enclosure should not exceed 95%. Starter's heat dissipation is approx. 3 x In (three times the current in watts). Example: For a 100A motor, heat dissipation is approx. 300 watts.Internal enclosure heating can be reduced through the use of: a. Additional ventilation b. Employing a by-pass contactor. Short Circuit Protection Protect the starter against a short circuit by Thyristor Protection Fuses. Control Terminals: Terminals 1-2Control supply 110-120Vac or 220-240Vac, 50/60Hz Terminal 3Ground Terminal 4Start Signal Input: Input form a N.O contact. To start the motor,connect common terminal (Terminal 6) to Terminal 4 for at least 500mSecs. Terminal 5 Soft Start Signal Input: Input form a N.C contact. To soft stop the motor,disconnect common terminal ( Terminal 6 ) to Terminal 5 for at least 500mSecs. Terminal 6Common Terminal,Common for terminals 4,5 Terminals 7-8Programmable Signal Relay,Programmable function: Run Relay(Normal Open): Changes its position when starter running(Start/Soft Stop process or Motor running). Over Current Fault Relay(Normal Close): Changes its position on Over Current Fault. Terminals 9-10By-pass relay, changes its position at the end of Acceleration Terminals 11-12Programmable Fault Relay,changes its position on fault, the contact is programmable to function as Normal Open or Normal Close relay Option Module 3) Field Bus Communication Connector: Modbus protocolCode AStandard RS485,Half duplex with Modbus protocol,baud rate 1200,2400,4800,9600 BPS Profibus protocol (Code B) DeviceNet protocol (Code C) RS232C (Code D)Starter control program on-line update 4) Analogue Signal Ouput: Analogue value is related to motor cuurent and operation supply voltage.
