1. Control of AC/DC current WITHOUT latching:When the value of the AC or DC current being controlled reaches threshold displayed on the front panel, the output relay changes status at the end of T2 (adjustable between 1 to 4 sec.). The relay immediately returns to its initial status when the current drops to bellow 5 to 50% of the threshold (hysteresis) or if the power supply is cut. Changing the hyster-esis value (via front panel) does not change the value of the preselected threshold.

2. Control of AC/DC current WITH latching:(Terminals Z1 and Z2 connected)When the value of the AC or DC current being controlled reaches the threshold displayed , the output relay changes status at the end of T2 and remains latched in this position. To reset the relay, contact between Z1 and Z2 must be opened or the power supply to the unit must be cut.
