Setting Plug
The E4PA-N is set up by aligning the notch on the Sensor with one
of the triangular marks on the Setting Plug and inserting the Setting
Plug into the Sensor.

Analog output characteristics
1. Increase: As the distance increases, the output in-
creases. (LED A1 flash.)
2. Decrease: As the distance increases, the output de-
creases. (LED A2 flash.)
3. Output from 0 mm: Increases from the sensing surface
to point A2. (LED A1 and A2 flash.) (See note 2.)

Analog Output Characteristics when Setting Plug is inserted at E2/
E3 Position:
The analog output characteristics will change from (1) to (2) to (3),
in that order, each time the Setting Plug is inserted with the E2/E3
position aligned with the notch on the Sensor.
2.
The analog output value can be compensated so that the sensing
surface (0 mm) of the Sensor is 4 mA/0 V regardless of the nearest
sensing point setting.
This function is useful when using Controllers without a scaling
function. Sensing is not possible, however, for characteristics
within the dead band distance and current/voltage output values
may not be stable.

Mutual Interference Prevention
The E4PA-N provides a sync input to prevent mutual interference.
When the fifth pin of the Sensor I/O Connector’s M12 Connector is interconnected, mutual interference can be prevented for up to five Units. The
Sensors will mutually oscillate, however, causing a delay in measurement time by the mutual interference cycle time per Sensor
×
number of Units
+ response time. When the sync inputs are not connected, the mutual interference prevention function is disabled.
(For example, if three E4PA-LS200-M1-N are connected, the response time for one Sensor is 34 ms
×
3 Sensors + 195 ms = 297 ms.
