Operation

Setup and Operating Procedure

The E4PA-N is factory-set for the decrease mode for analog output characteristics and for the maximum sensing range. These settings enable

scaling with the connected device (e.g., the K3NX). In this case, only step 4 is required.

To change the analog output range, follow steps 1 to 4 below.

1. Preparation for Setup

Note: Do not insert the Setting Plug yet. It must be inserted within

five minutes after the power is turned ON, however, or the set-

up will not be possible. If that happens, power up again and

start over.

2. Setting Sensing Range

3. Setting Analog Output Characteristics

Mode

4. Setting Temperature Compensation Mode

Note:

If the reflection from the Sensor is extremely weak, or if the sensing object is set outside of the sensing range, the error indicator (red) will

flash to show that the sensing range is not accurately set. If the Setting Plug is left removed for five minutes or longer, temperature com-

pensation will be disabled (status before setting).

If it becomes necessary to change the settings for step 2 (Sensing Range) or step 3 (Analog Output Characteristics Mode) after steps 1 through

4 have been completed, the contents of all the previous settings will be remembered, so only the items to be changed need to be reset. Go

through the steps in order, from 1 to 4, and reset only the items to be changed.

Step

Setting/Operation

1

Remove the Setting Plug.

2

Turn ON the power.

(See note.)

3

Proceed to Step 2 Setting Sensing Range.

Step

Setting/Operation

1

Place the sensing object at the nearest point within the sensing

range.

2

Insert the Setting Plug at the A1

position. (Align the notch on the

Sensor with the A1 triangular mark

on the Setting Plug.)

The power indicator (green) and

the A1 RUN indicator (yellow) with

flash, showing that the near dis-

tance has been correctly set.

3

Remove the Setting Plug. (In this

state, the setting is confirmed and

recorded.)

4

Place the sensing object at the farthest point within the sensing

range.

5

Insert the Setting Plug at the A2

position. (Align the notch on the

Sensor with the A2 triangular mark

on the Setting Plug.)

The power indicator (green) and

the A2 RUN indicator (yellow) will

flash, showing that the far distance

has been correctly set.

6

Remove the Setting Plug. (In this

state, the setting is confirmed and

recorded.)

7

Proceed to Step 3 Setting Analog Output Characteristics Mode.

Step

Setting/Operation

1

Insert the Setting Plug at the E2/E3

position. (Align the notch on the Sen-

sor with the E2/E3 triangular mark on

the Setting Plug.)

Note: Check the input impedance of connected devices

and the analog output in Ratings/Characteristics (see

page 2).

2

After the analog output characteristics have been set, remove the

Setting Plug.

3

Proceed to Step 4 Setting Temperature Compensation Mode.

Step

Setting/Operation

1

Insert the Setting Plug at the T posi-

tion. (Align the notch on the Sensor

with the T triangular mark on the Set-

ting Plug.)

2

Leave the Setting Plug inserted where it is. (This completes the set-

up.)

Note: To maintain the temperature compensation, leave

the Setting Plug inserted during operation. If it is re-

moved from the E4PA, the temperature compensa-

tion will be disabled.

A2 RUN indicator (yellow) flashing:

● Analog output characteristics: Decrease mode

In this mode, the analog output decreases

(20 to 4 mA/10 to 0 V) as the

sensing object nears the E4PA

within the sensing range.

A1 RUN indicator (yellow) flashing:

● Analog output characteristics: Increase mode

A1 and A2 RUN indicators (yellow) flashing at the same time:

● Analog output characteristics: Output from 0 mm

In this mode, the analog output

increases (4 to 20 mA/0 to 10 V)

as the sensing object nears the

E4PA within the sensing range.

In this mode, the analog output

decreases (20 to 4 mA/10 to 0 V)

as the sensing object nears the

E4PA between the farthest

sensing point and 0 mm.

The mode changes when the Setting Plug

is reinserted at the E2/E3 position.
