The ATC Diversified SLA Series is designed to protect 3-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). On models featuring

indicators, the LED glows when all line conditions are normal.

Both Delta and Wye systems may be monitored. In Wye systems, connec-

tions 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.

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 pro-

vide the required protection when properly adjusted.
