1 SLU SERIES Universal Phase Monitor/Relay SLU-100-ASA and SLU-100-ASD Plug-In MILLIMETERS DIN Rail DESCRIPTION Phase Monitor Relays (3-Phase Monitors) provide cost-effective protection against premature equipment failure caused by voltage faults on 3-Phase systems (Wye or Delta). Until recently, different phase monitors were required to address voltage range and protection requirements for each individual power and motor circuit. The SLU Series multimode phase monitoring relay, was designed for the convenience of electricians, maintenance managers and engineers. A single SLU Phase Monitoring Relay can be easily adjusted for the voltage, imbalance percentage and time delay requirements to protect against unbalanced voltages or single phasing regardless of any regenerative voltages. Both Delta and Wye systems may be monitored. In Wye systems, connections to neutral are not required. NOTE: Not recommended for generator or variable frequency drive applications. Call technical support for application assistance.

3 SLU SERIES Multi-Mode Phase Loss Monitor SLU-OEM1 TOP LABEL DESCRIPTION The OEM1 single-adjust setup provides full multi-fault protection. Phase Monitor Relays (3-Phase Monitors) provide cost-effective protection against premature equipment failure caused by voltage faults on 3-Phase systems (Wye or Delta). Until recently, different phase monitors were required to address voltage range and protection requirements for each individual power and motor circuit. The SLU-OEM1 is ideally suited for original equipment manufacturers since the unit provides a scalable voltage adjustment from VAC (3Ø). The SLU-OEM1 has built in power up and fault delays. To minimize incidences of nuisance tripping while protecting against most power quality conditions associated with premature motor failure. Variations of the SLU-OEM1 are available upon request. Modifications can be made on % Phase Loss/Imbalance, Fault/Restart Delay, Frequency Shift and proprietary part numbers for low minimum quantities. Both Delta and Wye systems may be monitored. In Wye systems, connections to neutral are not required. NOTE: Not recommended for generator or variable frequency drive applications. Call technical support for application assistance.

4 SLU SERIES 3-Phase Auto Ranging Rapid Cycling SLU-100-ASDS MILLIMETERS OPERATION The Line-to-Line voltage adjustment is set to the appropriate nominal voltage and frequency scale. There is infinite set point resolution between minimum and maximum on each scale. With normal operating voltage present on all three phases in the proper sequence, the internal relay will energize (pick-up). When an incorrect phase sequence, phase loss, under voltage, over voltage, frequency shift, or unbalance condition occurs greater than the settings, the internal relay will de-energize (drop-out). When all conditions return to normal and the adjustable Restart Delay expires, the relay will energize (pick-up). The Rapid Cycle lockout count must be less than 5. Both Delta and Wye systems may be monitored. In Wye systems, connections to neutral are not required.

DESCRIPTION The MotorGuardian TM is a microprocessor based overload relay, designed to provide protection for 3-Phase AC motors. It offers a broad range of features in one compact package providing a cost effective solution for monitoring and managing motor performance. A unique feature of the The MotorGuardian TM is its ease of installation. It is provided with Clamp- On C.T.'s that can accommodate up to 1500 ampere loads. Actual motor operating conditions are accessed by the scrolling menu and viewed by a two line highly visible vacuum fluorescent display. Fault conditions are also displayed indicating the specific cause of the occurring fault. There are two separate models that cover two input voltage ranges. The Model MPA-1000 has a direct input voltage range of VAC, 3-phase. The MPA-1100 has been designed to accept secondary volts from medium voltage transformers and has an input range of VAC, 3-phase. 282

8 PRA SERIES Phase Sequence Monitor Style A Style N Style A Style N 3.70" 3.225" DESCRIPTION The PRA-100 Series are designed to allow the output to energize only when the phase connections are in the proper sequence. For use in applications where motor direction is critical or the installation is required by code to have sequence detection. OPERATION When the phase sequence is correct and the operating voltage is present on all phases, the relay will energize and the green LED indicator will glow. If the phases are in reverse rotation, the relay will not energize and the red LED indicator will glow.

9 SLA SERIES Phase Loss, Under Voltage and Phase Sequence Monitor/Relays Style A Diversified Phase Monitors operate independently of motor size or power requirements of the system. Some typical applications follow: Air Handlers Conveyor Drive Oil & Gas Pumps Elevator Drives Irrigation Pumps Power Substation Monitoring Lift Station Pumps Computer Power Protection Water Waste & Sewage Machinery Sawmill & Woodpump Machinery Transfer Switching for Emergency Power Supplies Commercial/Industrial Air Conditioning & Refrigeration Compressors Robotics Equipment OPERATION The SLA Series is designed to protect three-phase equipment against Phase Loss, Under Voltage, and Phase Reversal conditions. With normal operating voltages applied in the proper ABC sequence, the internal relay will energize (PICK-UP). When incorrect phase sequence or phase loss occurs or the three-phase voltages fall below the drop out voltages, the relay will de-energize (DROP-OUT). Both Delta and Wye systems may be monitored. In Wye systems, connections to neutral are not required. For UL Listed units, with field wiring terminals, copper wire with 60 / 75 C rating must be used for control circuitry connections. On models featuring indicators, the LED glows when all line conditions are normal. NOTE: When a phase is lost while the motor is running, a condition known as regeneration occurs where a voltage is induced into the open phase nearly equal in magnitude to the normal phase-to-phase voltage. However, with the exception of lightly loaded motors, enough change is detected by the SLA to provide the required protection when properly adjusted.

13 PBC SERIES 3-Phase Voltage Band Monitor Relay Style E OPERATION The PBC Series offers protection to three-phase equipment that is required to operate between two voltage limits. All three phases are monitored individually for a pre-selected under and over voltage limit. With normal operating voltages applied, the internal relay will energize (PICK-UP). When the voltages on any or all phases fall outside the preset Over/Under trip points for loner than the Release delay, the relay will de-energize (DROP-OUT). When line conditions return to normal, the PBC Series Monitor automatically resets and the internal relay energizes. The LED fault indicators aid in set up and system trouble-shooting. The respective LED glows on fault condition. The LED indicators have an immediate response to voltage conditions and operate independently of the relay. The HYSTERESIS in each unit provides a differential of 4% between the PICK-UP and DROP-OUT trip points.

14 PBD SERIES 3-Phase Sequence and Voltage Band Monitor/Relays Style E OPERATION The PBD Series offers protection to three-phase sequence sensitive equipment that is required to operate between two voltage limits. All three phases are monitored individually for a pre-selected Under and Over voltage limit. With normal operating voltages applied in the proper ABC sequence, the internal relay will energize (PICK-UP). When the voltages on any or all phases fall outside the preset Over/Under trip points for longer than the Adjustable Release delay, the relay will de-energize (DROP-OUT). When line conditions return to normal, the PBD Series Monitor automatically resets and the internal relay energizes. Both Delta and Wye systems may be monitored. In Wye systems, connections to neutral are not required. The LED fault indicators aid in set up and system troubleshooting. The respective LED glows on fault condition. The LED indicators have an immediate response to voltage conditions and operate independently of the relay. In a phase reversal condition the LED indicators respond to voltage conditions but the relay will not energize. The Adjustable Release delay is provided to ignore momentary voltage fluctuations that cause nuisance tripping. The HYSTERESIS in each unit provides a differential of 4% between the PICK-UP and DROP-OUT trip points.
