E3X-NH
To set the initial threshold, perform One-point teaching by pressing the SET button for a minimum of 3 seconds.
As a result of target movement during operation, the middle value between the highest and lowest point on the incident scale will be
obtained. The E3X-NH will perform an auto-tuning function within a range of ±18% of this value.
The sensor will perform an Automatic Threshold Compensation within the preset band.
After the threshold has been compensated, the Threshold Indicator will flash, indicating the adjusted value.
Threshold compensation occurs at 1, 3, 6, 10, 15, 22, and 30 minutes after turning on the E3X-NH. After the initial 30 minute time-
frame, Threshold Compensation is continually repeated, every 30-minutes.
Alarm output will occur if the threshold compensation range is not within the tuning range. Perform sensitivity setting again if the alarm
signal turns ON.
