Technical Documentation

 

Non-Latching Mode:
The unit will operate in the non-latching mode if no circuit is completed across pins 9 & 11. After input voltage is applied (LED is Green) and the start-up sensing delay (ts) of 0.1 – 10 seconds is completed, the relay will energize when the monitored current is above the adjustable pick-up setting (“Threshold”). The LED will be Red. It will de-energize when the monitored current goes below the adjustable drop-out setting (“Hysteresis”) by 5-50% of the selected pick-up setting or when input voltage is removed. The LED will be Green. 

 

Latching Mode:
The unit will operate in the latching mode if a N.C. contact (Memory S2) is connected across pins 9 & 11 (see Wiring Diagram). After input voltage is applied (LED is Green) and the start-up sensing delay (ts) of 0.1 – 10 seconds is completed, the relay will energize when the monitored current is above the adjustable pick-up setting (“Threshold”). The LED will be Red. It will de-energize when the monitored current goes below the adjustable drop-out setting (“Hysteresis”) by 5-50% of the selected pick-up setting and the N.C. contact (Memory S2) is opened, or when input voltage is removed. The LED will be Green. It is recommended to set the Hysteresis at 5% when in the latching mode.
