To have a correct working of the instrument occurs to program
the value of the primary of the TA transformer using the fitting
microswitches positioned on the backside of the device.
Now the visualization corresponds to the same value of the
input current. Then adjust the set point value, the delay timing,
the Hysteresis and the time of Inhibit.
When the current absorption is over the setted set point value
there is the intervention with the commutation of the relay
contacts. The intervention will be in function of the
programmed delay timings; the restore will be in function of the
programmed hysteresis. To excluded the memorization of the
intervention it is necessary to make a bridge between the
inputs 12 - 14
