The SCAL unit begins the 30 second self-calibration process the rst time current is applied in the operating range. The
threshold is then set. Subsequent calibrations may be performed by moving SW1 to the position opposite of its current
position with or without current applied (hands can be safely away from live voltage). Once current begins owing, or if it
already is, the calibration process will begin. At the end of the 30 seconds, amperage will be read and set as the threshold.
SW2 in the ON position provides a 15% (+/-3%) dierential. In the OFF position, it provides a 25% (+/-3%) dierential. SW2
can be selected at anytime and does not aect the threshold setting. Current in-range closes the sensor contact. Current
above or below range opens the sensor contact.
Example: With a current of 10 amps set as the threshold and a 15% dierential, sensor contact will be closed between 8.5
amps and 11.5 amps and open outside of this range. A small amount of hysteresis is provided to prevent dithering near the
dierential limits.
