It has built-in bypass for easy installation and energy saving. A RUN, TOR and Event signal is available from relay outputs in NO (normally open state). The PSTX has functions such as current limit, kickstart, analog output, EOL, motor heating and pump cleaning. PSTX also features features jog, braking, stand-still brake, diagnostics, sequence start and emergency/fire pump mode as standard.To interact with PSTX, it has a detachable full graphic display with IP66 and 4x outdoor rating. There are four ways to communicate with PSTX. It can be done by hardwire inputs Start/Stop/Reset of fault, and by three programmable digital inputs. Another popular option is the built-in Fieldbus communication Modbus RTU and incl optional ANYBUS modules with every major protocol such as for example Profinet, Profibus, Modbus TCP, Ethernet IP and others. Another way to communicate with PSTX is to use an external adaptor and a Fieldbus plug. PSTX is the complete alternative for any motor starting application. It’s suitable for medium to large-sized three-phase motors with nominal currents from 30...1250 A inline connection or 52...2160 A inside delta connection. Typical applications are, for example, pumps, fans, compressors, and conveyors

Core Architectural Features
Built-In Bypass Contactor: Equipped with an integrated mechanical bypass contactor, this soft starter automatically switches current through the bypass circuit once the motor achieves full operational speed. This intelligent design effectively reduces internal heat generation within the control cabinet, removes the need for external contactor accessories, lowers overall system costs, and minimizes long-term energy consumption for sustainable operation.
Precision Torque Control for Fluid Systems: Differing from conventional soft starters that only adopt linear voltage ramp control, this unit utilizes advanced torque control algorithms. By regulating motor torque instead of simple voltage adjustment, it effectively suppresses sudden pressure fluctuations and eliminates damaging water hammer (water slag) phenomena in complex piping systems, protecting pipeline equipment and stabilizing fluid system operation.
Comprehensive Multi-Dimensional Motor Protection: Functioning as an all-round motor monitoring and protection device, the soft starter integrates complete electronic protection mechanisms to safeguard motor operation. Key protection functions include PT-100 and PTC motor sensor input monitoring, earth fault protection, phase reversal detection, as well as locked rotor and underload monitoring. The underload detection feature is critical for identifying dry-running pump conditions, preventing equipment damage and unexpected downtime.
Detachable Multilingual Graphic Keypad: The device is fitted with a full-graphic multilingual display that supports up to 17 global languages. The fully detachable keypad can be independently installed on cabinet doors, allowing operators to adjust operational parameters, check real-time data, and review historical logs safely without opening live electrical cabinets, improving on-site operational safety and convenience.
Flexible Industrial Automation Connectivity: This soft starter comes with native Modbus RTU communication protocol as standard for basic industrial data transmission. It supports flexible communication expansion via optional Anybus modules, enabling seamless connection with mainstream industrial protocols including Profinet, EtherNet/IP, DeviceNet, and Modbus TCP, ensuring excellent compatibility with various integrated automation platforms.
