E3X-NH
J THRESHOLD LEVEL AND INDICATOR LEVELS
Setting the Initial Threshold
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.

Threshold Compensation

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.
