<strong>Model</strong> 102AThe <strong>Model</strong> 102Ais an auto-ranging voltage monitor designed to protect 3-phase motorsregardless of size. It is used on 190-480VAC, 50*/60Hz motors toprevent damage caused by incoming power problems.Available <strong>Model</strong>s:102A102A-2102A-3102A-9102-600A unique microcontroller-based voltage and phase-sensing circuitconstantly monitors the 3-phase voltages to detect harmful power lineconditions.When a harmful condition is detected, the MotorSaver's outputrelay is deactivated after a specified trip delay. The output relay reactivatesafter power line conditions return to acceptable levels. The <strong>Model</strong> 102Aincludes advanced single LED diagnostics. Five different light patternsdistinguish between faults and normal conditions.See Appendix A, Figures 7 & 8 for typical wiring diagrams.Features2 - Variable Restart Delay (Manual, 2-300 seconds)3 - Variable Trip Delay (2-30 seconds)9 - High Voltage Detection• Low voltage trip• Optional high voltage trip• Single-phase trip• Reverse-phase trip• Fixed 6% voltage unbalance trip• Single LED diagnostics• Separate indicators for:Power-up restart delayReverse-phase tripGood voltage/relay energizedUnbalance/single-phase tripHigh/low voltage tripSpecifications3-Phase Line Voltage102A• • • • • • • • • • • • • • • • • • • • • • • • 190-480VAC102-600 • • • • • • • • • • • • • • • • • • • • • • 475-600VACFrequency • • • • • • • • • • • • • • • • • • • 50*/60HzLow Voltage (% of setpoint)Trip • • • • • • • • • • • • • • • • • • • • • • • • 90%Reset • • • • • • • • • • • • • • • • • • • • • • • 93%Voltage Unbalance (NEMA)Trip • • • • • • • • • • • • • • • • • • • • • • • • 6%Reset • • • • • • • • • • • • • • • • • • • • • • • 4.5%Trip Delay TimeLow/High Voltage • • • • • • • • • • • • • • • • 4 seconds (standard)Unbalance & Phasing Faults• • • • • • • • • • 2 secondsRestart Delay TimeAfter a Fault • • • • • • • • • • • • • • • • • • • 2 seconds (standard)After a Complete Power Loss• • • • • • • • 2 seconds (standard)Output Contact RatingSPDT • • • • • • • • • • • • • • • • • • • • • • • 480VA @ 240VAC Pilot Duty• • • • • • • • • • • • • • • • • • • • • • • • • 10A @ 240VAC General PurposeTransient Protection (Internal) • • • • IEC 1000-4-5; 1995 ±6kVPower Consumption • • • • • • • • • • • 5 Watts (max.)Weight • • • • • • • • • • • • • • • • • • • • • 14 oz.Available Options(2) Adjustable Restart Delay • • • • • • • • • Manual, 2-300 seconds(3) Adjustable Trip Delay • • • • • • • • • • • 2-30 seconds(Phasing and unbalance trip delay remains at 2 seconds)(9) High Voltage Operating PointsTrip (% of Setpoint) • • • • • • • • • • • • • • 110%Reset (% of Setpoint) • • • • • • • • • • • • • 107%*Note: 50Hz will increase all delay timers by 20%.www.symcom.com • tel: 605-348-5580 800-843-8848 • fax: 605-348-568515
