Overview
The DF-G1 is an easy-to-use, DIN-rail-mountable fiber optic sensor. It provides high-performance sensing in low-contrast applications.
The sensor’s compact housing has dual digital displays (Red/Green) and a bright output LED for easy programming and status monitor-
ing during operation. The sensor features a single discrete output, either NPN or PNP, by model.
The DF-G1 features increased 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 27).

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 3 ). ADJ
mode allows the user to perform Expert TEACH/SET methods and Manual Adjust (see Adjust Mode on page 7 ).
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 Figure 8. on page 12 .
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.
Run Mode
Run mode allows the sensor to operate normally and prevents unintentional programming changes. The +/SET/- rocker button is disabled
during RUN mode, except when using Window SET, see Figure 8. on page 12 .

Program Mode
Program (PRG) mode allows the following settings to be programmed in the DF-G1 (refer to diagrams on pages 6-7 for programming).
TEACH Selection
The DF-G1 can be programmed for one of the following TEACH/SET methods:
• Two-Point TEACH
• Dynamic TEACH
• Window SET
• Light SET
• Dark SET
• Calibration SET
NOTE: A TEACH Selection must be selected by programming before TEACH/SET methods can be used.
Response Speed
The DF-G1 can be programmed for one of the following Response Speeds:
Response Speed Display Range Crosstalk Avoidance Algorithm
200 us (High Speed) 0 - 4000 Disabled
500 us (Standard) 0 - 4000 Enabled
2000 us (Long Range) 0 - 9999 Enabled
5000 us (Extra Long Range) 0 - 9999 Enabled
Offset Percent
The Offset Percent is used during the Window, Light, or Dark SET methods. The threshold(s) are positioned a programmable % offset
from the taught condition. The allowable range depends upon the Response Speed Mode, as shown below:
Response Speed MIN % MAX %
200 us (High Speed) 10 999
500 us (Standard) 10 999
2000 us (Long Range) 2 999
5000 us (Extra Long Range) 2 999
The offset percent can also be programmed to Minimum Offset. This allows the DF-G1 to set the threshold(s) as close
as possible to the presented condition, but still provide for reliable sensing.
NOTE: Offset Percent MUST be programmed to Minimum Offset for Dark SET to accept conditions of no
signal (0 counts).
Auto Thresholds
Auto Thresholds can be programmed to be ON/OFF. The Auto Thresholds algorithm continuously tracks slow changes in the taught
condition(s), and optimizes the threshold(s) to provide for reliable sensing. For Two-Point and Dynamic TEACH, the algorithm optimizes
the threshold to be centered between the light and dark conditions. For Window, Light, and Dark SET, the algorithm optimizes the thresh-
old(s) to maintain the programmed Offset Percent from the taught condition.

• After programming Auto Thresholds to ON, it is highly recommended to re-perform the TEACH/SET method
• Manual Adjustments are disabled when Auto Thresholds are ON
• Auto Thresholds are automatically disabled in Calibration SET (see Calibration SET on page 17)
• Severe contamination/changes in the taught condition can prevent the Auto Thresholds algorithm from optimizing the threshold(s). If
this occurs, the DF-G1 will enter a Threshold Alert or Threshold Error state. See Troubleshooting on page 19 for more explana-
tion.
Delays/Timers
ON/OFF Delays and ON/OFF One-Shot timers
can be programmed between 1 - 9999 ms (a val-
ue of 0 disables the delay/timer). Figure 2 de-
fines how the delays/timers affect the output be-
havior.
Some combinations of delays/timers are not al-
lowed. The DF-G1 programming menu automati-
cally disables invalid combinations of delays/
timers. The following table shows the allowable
combinations of delays/timers:

Display Readout
The readout of the digital displays can be programmed for the following options:
• Signal/Threshold readout - Numeric (1234) or % (123P)
• ECO mode - Enabled or Disabled (ECO mode dims the displays to reduce current consumption)
• Display Orientation - Normal ( ) or Flipped ( )
Gain Selection
The DF-G1 can operate in Auto Gain mode or the Gain can be fixed to be in Gain 1…8. In Auto Gain, the DF-G1 optimizes the gain
during a TEACH/SET method for the presented condition(s). While viewing the fixed gains in the Gain Selection choice list, the DF-G1
will automatically switch to the selected gain and display the measured signal on the Red display. This allows for easy and quick evalua-
tion of the fixed gain mode.
Factory Defaults
The Factory Defaults menu allows the DF-G1 to be easily restored back to original factory default settings (see Factory Default Settings
in Specifications on page 20).

Adjust Mode
Sliding the RUN/PRG/ADJ mode switch to the ADJ position allows the user to perform Expert TEACH/SET methods and Manual Adjust-
ment of the threshold(s).
Two-Point TEACH
• Establishes a single switching threshold
• Threshold can be adjusted using “+” and “-” rocker button (Manual Adjust)
Two-Point TEACH is used when two conditions can be presented statically to the sensor. The sensor locates a single sensing threshold
(the switchpoint) midway between the two taught conditions, with the Output ON condition on one side, and the Output OFF condition on
the other (see Figure below).

Dynamic TEACH
• Teaches on-the-fly
• Establishes a single switching threshold
• Threshold can be adjusted using “+” and “-” rocker button (Manual Adjust)
Dynamic TEACH is best used when a machine or process may not be stopped for teaching. The sensor learns during actual sensing
conditions, taking multiple samples of the light and dark conditions and automatically setting the threshold at the optimum level (see
Figure below).

Troubleshooting
Manual Adjustments Disabled
Manual adjustments are disabled when Auto Thresholds are ON. If a manual adjustment is attempted while Auto Thresholds are ON, the
Green display will flash .
% Minimum Difference after TEACH
The Two-Point and Dynamic TEACH methods will flash a % minimum difference on the displays after a PASS or FAIL.
Value PASS/FAIL Description
0-99% FAIL The difference of the taught conditions does not meet the required minimum
100-300% PASS The difference of the taught conditions just meets/exceeds the required minimum, minor sensing
variables may affect sensing reliability
300-600% PASS The difference of the taught conditions sufficiently exceeds the required minimum, minor sensing
variables will not affect sensing reliability
600% + PASS The difference of the taught conditions greatly exceeds the required minimum, very stable opera-
tion
% Offset after SET
The Window, Dark, and Light SET methods will flash a % offset on the displays after a PASS or FAIL.
SET Result % Offset Meaning
PASS (with % Offset) Displays the % offset used for the SET method
FAIL (with % Offset) Displays the minimum required % offset necessary to PASS the SET method
FAIL (without % Offset) Presented condition cannot be used for the SET method
Threshold Alert or Threshold Error
Severe contamination/changes in the taught condition can prevent the Auto Thresholds algorithm from optimizing the threshold(s).
State Display Description Corrective Action
Threshold Alert Alternates
and
The threshold(s) cannot be optimized,
but the sensor's output will still contin-
ue to function
Cleaning/correcting the sensing environment
and/or a re-teach of the sensor is highly rec-
ommended
Threshold Error The threshold(s) cannot be optimized,
and the sensor's output will stop func-
tioning
Cleaning/correcting the sensing environment
and/or a re-teach of the sensor is required
