================================================================================ SIMPRONICS ELECTRONICS & EMBEDDED SYSTEMS TECHNICAL DATASHEET: SENWER LITE - SMART ELECTRONIC WATER-LEVEL & ENERGY REGULATOR ================================================================================ 1. PRODUCT OVERVIEW -------------------------------------------------------------------------------- The Simpronics SENWER Lite is a microcontrolled smart water-level and energy regulator designed to automatically regulate water pumps for residential, commercial, and agricultural tanks. Featuring a digital 0.96-inch OLED display, capacitive touch controls, and smart telemetry, it monitors overhead (OHT) and underground (UGT) tanks concurrently, protecting pumps from dry-running, saving electrical power, and preventing water overflow. 2. ELECTRICAL CHARACTERISTICS -------------------------------------------------------------------------------- - Input Voltage: 180V - 240V AC, 50Hz - Relay Contact Rating: Up to 20A Direct resistive load (max 2HP motor) - Sensor Circuit Voltage: 5V AC peak-to-peak (prevents probe electrolysis) - Display: 0.96-inch Crisp Monochrome OLED (Level %, Status, BT) - User Controls: Capacitive Touch Keys (Power, Up, Down Navigation) - Surge Protection: Metal Oxide Varistor (MOV) rated at 440V / 4kV clamp - Idle Power Consumption: < 1.2 Watts 3. MECHANICAL SPECIFICATIONS -------------------------------------------------------------------------------- - Enclosure Material: Durable Flame-Retardant ABS Plastic Body - Front Panel: High-Gloss Scratch-Resistant Toughened Glass - Protection Rating: IP54 Dust & Splash Protection - Dimensions: 120mm (W) x 78mm (H) x 57mm (D) - Mounting Type: Wall-Mount with integrated side screw flanges 4. PIN CONFIGURATION & WIRING DETAILS -------------------------------------------------------------------------------- - Pin 1-2: AC Mains input (Phase & Neutral, 230VAC) - Pin 3-4: Motor Output relay terminals (Heavy-duty 20A SPDT) - Pin 5: Underground Tank Common (UGT-C) - Pin 6: Underground Tank Low Level (UGT-L) - Pin 7: Underground Tank High Level (UGT-H) - Pin 8: Overhead Tank Common (OHT-C) - Pin 9: Overhead Tank Low Level (OHT-L) - Pin 10: Overhead Tank High Level (OHT-H) 5. OPERATING PRINCIPLES -------------------------------------------------------------------------------- - Pump triggers ON when: UGT has sufficient water AND OHT water level falls below OHT-L. - Pump triggers OFF when: OHT water level reaches OHT-H OR UGT water level drops below UGT-L. - Dry-Run Protection: If pump is ON but sensor OHT-L does not detect water within 180 seconds, controller enters dry-run lockout mode. - Energy Regulation: Optimized pump duty cycle prevents motor overheating and reduces unnecessary starts. 6. COMPLIANCE & SAFETY WARNINGS -------------------------------------------------------------------------------- - Do not route sensor wires alongside AC power lines to prevent signal interference. - Always isolate mains AC before touching terminal blocks. - RoHS compliant. CE certified design. Designed & Engineered in India by Simpronics.
