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.

3.2.1 TEACH Selection
The DF-G2 can be programmed for one of the following TEACH/SET methods:
• Two-Point TEACH
• Dynamic TEACH
DF-G2 High Speed Expert™Dual Display Fiber Amplifier
8 www.bannerengineering.com - Tel: [phone]

• Window SET
• Light SET
• Dark SET
• Calibration SET
NOTE: A TEACH Selection must be selected by programming before TEACH/SET methods can be used.
3.2.2 Response Speed
The DF-G2 can be programmed for one of the following Response Speeds:
Response Speed Display Range Crosstalk Avoidance Algorithm
10 µs (Super High Speed) 0 – 4000 Disabled
15 µs (High Speed) 0 – 4000 Disabled
50 µs (Fast) 0 – 4000 Disabled
250 µs (Standard) 0 – 4000 Enabled
500 µs (Medium Range) 0 – 9999 Enabled
1000 µs (Long Range) 0 – 9999 Enabled
2000 µs (Long Range with immunity to
Energy Efficient Lights) 0 – 9999 Enabled
3.2.3 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 %
10 µs 5 999
15 µs 5 999
50 µs 2 999
250 µs 2 999
500 µs 1 999
1000 µs 1 999
2000 µs 1 999
The offset percent can also be programmed to Minimum Offset. This allows the DF-G2 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).
3.2.4 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 threshold(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 20)
DF-G2 High Speed Expert™Dual Display Fiber Amplifier
www.bannerengineering.com - Tel: [phone]

• Severe contamination/changes in the taught condition can prevent the Auto Thresholds algorithm from optimizing
the threshold(s). If this occurs, the DF-G2 enters a Threshold Alert or Threshold Error state. See
Troubleshooting on page 21 for more explanation.
3.2.5 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 3 on page 10 defines how
the delays/timers affect the output
behavior.
Some combinations of delays/timers are not
allowed. The DF-G2 programming menu
automatically disables invalid combinations
of delays/timers. The following table shows
the allowable combinations of delays/
timers:

ON Delay OK N/A - OK
ON One-Shot Timer N/A N/A OK -
3.2.6 Gain Selection
The DF-G2 can operate in Auto Gain mode or the Gain can be fixed to be in Gain 1...8. In Auto Gain, the DF-G2 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-G2 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.
3.2.7 Factory Defaults
The Factory Defaults menu allows the DF-G2 to be easily restored back to original factory default settings (see Factory
Default Settings in Specifications).
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 ( )
3.3 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 4 on page 11. Follow the instructions in the TEACH/SET sections in Adjust
Mode on page 12 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.

3.4.4 Light SET
• Sets a threshold a programmable % offset below the presented condition
• Changes output state on any condition darker than the threshold condition
• Threshold can be adjusted using "+" and "-" rocker button (Manual Adjust)
• Recommended for applications where only one condition is known, for example a stable light background with
varying darker targets
• See Program Mode for programming the Offset Percent setting
A single sensing condition is presented, and the sensor positions a threshold a programmable % offset below the
presented condition. When a condition darker than the threshold is sensed, the output either turns ON or OFF, depending
on the LO/DO setting.
