1.2 Overview

The DF-G2 is an easy-to-use, DIN-rail-mountable fiber optic sensor with best in class response speed and repeatability. It

provides high-performance sensing in high speed or low contrast applications where fast response time is required.

The sensor’s compact housing has dual digital displays (Red/Green) and a bright output LED for easy programming and

status monitoring during operation. The sensor features a single discrete output, either NPN or PNP, by model.

The DF-G2 features improved temperature compensation compared with previous fiber optic sensors. An accessory clamp

is available to secure a bank of connected sensors together on a DIN rail (see

Accessories

on page 29).

1.3 Top Panel Interface

Opening the dust cover provides access to the top panel interface. The top panel interface consists of the RUN/PRG/ADJ

mode switch, LO/DO switch, +/SET/- rocker button, dual red/green digital displays, and output LED.

RUN/PRG/ADJ Mode Switch

The RUN/PRG/ADJ mode switch puts the sensor in RUN, PRG (Program), or ADJ (Adjust) mode. RUN mode

allows the sensor to operate normally and prevents unintentional programming changes via the +/SET/-

button. PRG mode allows the sensor to be programmed through the display driven programming menu (see

Program Mode

on page 7 ). ADJ mode allows the user to perform Expert TEACH/SET methods and

Manual Adjust (see

Adjust Mode

on page 12 ).

LO/DO Switch

The LO/DO switch is used to select Light Operate or Dark Operate mode. In Light Operate mode, the output

is ON when the sensing condition is above the threshold (for Window SET, the output is ON when the

sensing condition is inside the window). In Dark Operate mode, the output is ON when the sensing condition

is below the threshold (for Window SET, the output is ON when the sensing condition is outside the

window).

+/SET/- Rocker Button

The +/SET/- rocker button is a 3-way button. The +/- positions are engaged by rocking the button left/

right. The SET position is engaged by clicking down the button while the rocker is in the middle position. All

three button positions are used during PRG mode to navigate the display driven programming menu. During

ADJ mode, SET is used to perform TEACH/SET methods and +/- are used to manually adjust the

threshold(s). The rocker button is disabled during RUN mode, except when using Window SET, see

Window

SET

on page 15.

Red/Green Digital Displays

During RUN and ADJ mode, the Red display shows the signal level and the Green display shows the

threshold. During PRG mode, both displays are used to navigate the display driven programming menu.

Output LED

The output LED provides a visible indication when the output is activated.
