SETUP & ADJUSTMENT
1.Install sensor over conductor and wire as shown in the connection diagram.
2.The sensor is shipped with the multi-turn adjustment set to the most sensitive position (CW). If the sensor now operates, turn the adjustment counter-clockwise (CCW) until the operation reverses. The smart LED will indicate this action.
3.Now turn the adjustment CW until the sensor just operates its controlled circuit. It is desirable to turn the adjustment slightly beyond this threshold point to provide a margin for normal current variations.
4.The smart LED eliminates the need for a voltmeter. The LED will switch from rapid to slow flashing when going below the trip point.
Note 1: For loads above highest range selection use an external current transformer with an appropriate ratio(I.E. 500:5), feed C.T. secondary one turn through window of unit.
Note 2: Locked rotor current of 2.5 times the range setting for longer than 5 seconds can damage the unit.
