Setting the I% and Hysteresis value in case of overcurrent:
Example: Current threshold = 13A
The maximum current range of RM35JA32MW =15A (as per catalogue)
So, the 100% setting of the % I potentiometer will be equivalent to = 15 A
For 13A setting of the %I potentiometer is 13 / 15 = 86.66%
Set hysteresis to 15%.
Thus, theoretically, if the current exceeds above 13 A , the control relay shall open after taking into consideration the Delay time adjustment. The control relay will close again once the current is below the Threshold => 13 A - 15% hysteresis (13 -0.15*13 = 11.05).
It is possible to program I% and Hysteresis value as per the requirement.
