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/- rocker button. PRG mode allows the sensor to be programmed through the display-driven
programming menu (see Program Mode on page 9 ). ADJ mode allows the user to perform Expert
TEACH/SET methods and Manual Adjust (see Adjust Mode on page 13 ).
LO/DO Switch
The LO/DO switch selects 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 17.
Red/Green Digital Displays
During RUN and ADJ modes, 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.

DF-G1 Expert™ Dual Display Fiber Optic Light Receiver
2 External Light Detection Considerations
External lighting variations must be carefully considered when applying this sensor because the amount of background
light can measurably affect detection reliability.
The DF-G1 Fiber Optic Light Receiver detects both the light of interest and ambient light. Figure 2 on page 5 shows
simulated light levels for both the dark state and the light state. The dark state is the amount of light detected when the
external light of interest is not present. Conversely, the light state is the amount of light detected when both the ambient
and external light of interest are present. In the dark state, the graph shows that light detected can change with time.
Changes in the dark state light levels are caused by variations in the ambient light levels (perhaps sunlight or factory light
variations). Typical variations in the detected light level when the external light of interest is present (light state) are also
shown in the figure. Note again that the light level can vary with changes in the ambient light level.

Figure 2. Light Levels
A successful sensing application is obtained when the sensor can detect between the light and dark conditions. Two
important points shown in Figure 2 on page 5 are the brightest dark level (BD) and the darkest light level (DL). These
values represent the key values for determining if the application will be successfully detected. The application goal is to
maximize the light level detected in the darkest light state. Using this concept of contrast, calculate the contrast available
to ensure a good sensing application. The contrast should be greater than 2 for robust sensing applications.
Contrast = DL/BD
The DF-G1 Fiber Optic Light Receiver detects light over a wide range of the light spectrum and over a wide range of light
intensity. Table 1 on page 5 and Table 2 on page 5 depict the typical minium light intensity as well as the maximum
light intensity values that can be detected. Use the tables as a guide for comparing detectable light levels for various light
sources. In Table 1 on page 5, values for the light intensity are in Lux and in Table 2 on page 5 values for light
intensity are in µW/cm².

DF-G1 Expert™ Dual Display Fiber Optic Light Receiver
The two tables above are a guide for detecting external lights. The sensor does not measure absolute light levels. It
detects the presence of an external light source based on the received light intensity relative to a user-set threshold.
These tables demonstrate that the sensor will detect light sources typical in many industrial applications and highlights
that the selection of the fiber optic cable diameter affects the limits of light detection.

4.2.2 Response Speed
The DF-G1 can be programmed for one of the following Response Speeds:
Response Speed
Display Range
Crosstalk Avoidance Algorithm
50 ms
0 – 9999
Disabled
150 ms
0 – 9999

4.2.3 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 %
50 ms
10
999
150 ms
10
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).
4.2.4 Delays/Timers
ON/OFF Delays and ON/OFF One-Shot
timers can be programmed between 1 9999 ms (a value of 0 disables the delay/
timer). Figure 4 on page 11 defines how
the delays/timers affect the output
behavior.
ON
Output
OFF
OFF Delay
Some combinations of delays/timers are not
allowed. The DF-G1 programming menu
automatically disables invalid combinations
of delays/timers. When invalid timing
functions are attempted, only the last
timing function will be implemented. For
example, if an Off Delay is selected and
then an On One-Shot Timer is added, this
invalid combination will force the sensor to
have the On One-Shot Timer function and
not have the Off Delay.The following table
shows the allowable combinations of
delays/timers:

4.2.5 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 (
)
4.2.6 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 evaluation of the fixed gain mode.
4.2.7 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 25).
4.3 Remote Input
The remote input may be used to perform TEACH/SET methods and to program the sensor remotely. Connect the white
input wire of the sensor to ground (0 V dc), with a remote switch connected between them. Pulse the remote input
according to the diagram shown in Figure 5 on page 13. Follow the instructions in the TEACH/SET sections in Adjust
Mode on page 13 to perform a TEACH/SET method.
The sensor exits TEACH and remote programming modes after a 60 second timeout. Users may exit TEACH and remote
programming modes by setting the remote input low for more than 2 seconds. In either case, the sensor returns to Run
mode without saving any new settings.

4.4.3 Window SET
•
•
•
•
•
Sets window thresholds that extend a programmable % offset above and below the presented condition
All other conditions (lighter or darker) cause the output to change state
Sensing window center can be adjusted using "+" and "-" rocker button (Manual Adjust)
Recommended for applications where a product may not always appear in the same place, or when other signals
may appear
See Program Mode on page 9 for programming the Offset Percent setting (to increase/decrease the window size)
A single sensing condition is presented, and the sensor positions window thresholds a programmable % offset above and
below the presented condition. In LO mode, Window SET designates a sensing window with the Output ON condition inside
the window, and the Output OFF conditions outside the window.
NOTE: For Window SET and Light SET, the maximum offset threshold percent is 90%.

Value
PASS/FAIL
Description
0 to 99%
FAIL
The difference of the taught conditions does not meet the required minimum
100 to 300%
PASS
The difference of the taught conditions just meets/exceeds the required minimum,
minor sensing variables may affect sensing reliability
300 to 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 operation
