Protection Relays Voltage Monitoring Relays PLS SERIES Description The PLS Series is a low cost phase sensitive control that provides an isolated contact closure when the proper A-B-C phase sequence is applied. Protects sensitive 3-phase equipment and equipment operators from reverse rotation. Designed to be compatible with motor overloads or other 3-phase equipment protection devices. Protection for equipment control centers where frequent reconnection or electrical code makes reverse rotation protection essential. Examples include: mobile refrigerated containers, construction equipment, hoists, pumps, conveyors, elevators and escalators. 8-PIN Operation The internal relay and LED are energized when the phase sequence is correct. The output relay will not energize if the phases are reversed. Reset is automatic upon correction of the fault. Wiring Diagram Features & Benefits FEATURES BENEFITS F = Fuses A = Phase A = L1 Cost effective protection of 3-phase equipment and B = Phase B = L2 Continuous monitoring operators from reverse rotation. Meets reverse C = Phase C = L3 rotation protection code requirements.
