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,
CH1/CH2 switch, +/SET/- rocker buon, 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 unintenonal programming changes via
the +/SET/- rocker buon.
• 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).
CH1/CH2 Switch (Dual Output Mode)
The CH1/CH2 switch selects which output's parameters can be accessed and changed in the interface of the
display.
+/SET/- Rocker Buon
The +/SET/- rocker buon is a 3-way buon. The +/- posions are engaged by rocking the buon le/right. The SET
posion is engaged by clicking down the buon while the rocker is in the middle posion. All three buon posions
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 buon is disabled
during RUN mode, except when using Window SET.
Red/Green Digital Displays
During RUN and ADJ modes, the Red display shows the signal level, and the Green display shows the threshold or
the total counts. During PRG mode, both displays are used to navigate the display-driven programming menu.
Dual Output LEDs
The output LEDs provide a visible indicaon when the associated output is acve (conducng).

3.2.4 Oset Percent
The Oset Percent is used during the Window, Light, or Dark SET methods. The threshold(s) are posioned a programmable % oset
from the taught condion.
The allowable oset percent range varies based on the response speed, teach method and sensivity sengs as shown below:
Teach Method Response Speed Sensivity Oset % Range
Window Set, Light Set 50 µs, 250 µs High 2 to 98%
Standard 5 to 95%
Low 10 to 90%
500 µs, 1000 µs, 2000 µs High 1 to 99%

500 µs, 1000 µs, 2000 µs High 1 to 999%
Standard 2 to 999%
Low 5 to 999%
3.2.5 Auto Thresholds
Auto Thresholds can be programmed to be ON/OFF. The Auto Thresholds algorithm connuously tracks slow changes in the taught
condion(s), and opmizes the threshold(s) to provide for reliable sensing. For Two-Point and Dynamic TEACH, the algorithm opmizes
the threshold to be centered between the light and dark condions. For Window, Light, and Dark SET, the algorithm opmizes the
threshold(s) to maintain the programmed Oset Percent from the taught condion.
•Aer 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 automacally disabled in Calibraon SET (see Calibraon SET on page 20)
• Severe contaminaon/changes in the taught condion can prevent the Auto Thresholds algorithm from opmizing the
threshold(s). If this occurs, the DF-G2 enters a Threshold Alert or Threshold Error state. See Troubleshoong on page 21 for
more explanaon.

3.2.6 Delays/Timers
ON/OFF Delays and ON/OFF One-Shot mers
can be programmed independently for both CH1
and CH2 for a me period between between 1 -
9999 ms (a value of 0 disables the delay/mer).
Figure 6 on page 11 denes how the delays/
mers aect the output behavior.
Some combinaons of delays/mers are not
allowed. The DF-G2 programming menu
automacally disables invalid combinaons of
delays/mers. The following table shows the
allowable combinaons of delays/mers:

3.2.7 Sensivity Selecon
The Sensivity Selecon can be programmed independently for CH1 and CH2. Use this seng to increase (lo) or decrease (high) the
switch-point hysteresis from the default (std) seng.
• high—High sensivity. Use this seng for low contrast sensing
• Std—Standard sensivity
• Lo—Low sensivity. Use this seng to stabilize the output in high vibraon applicaons
3.2.8 Display Readout
The readout of the digital displays can be programmed for the following opons:
• Signal/Threshold readout - Numeric (1234) or % (123P)
•ECO mode - Enabled or Disabled (ECO mode dims the displays to reduce current consumpon)
• Display Orientaon - Normal ( ) or Flipped ( )
3.2.9 Gain Selecon
The DF-G2 can operate in Auto Gain mode or the Gain can be xed to be in Gain . In Auto Gain, the DF-G2 opmizes the
gain during a TEACH/SET method for the presented condion(s). While viewing the xed gains in the Gain Selecon choice list, the DF-
G2 will automacally switch to the selected gain and display the measured signal on the Red display. This allows for easy and quick
evaluaon of the xed gain mode.
3.2.10 Factory Defaults
The Factory Defaults menu allows the DF-G2 to be easily restored back to original factory default sengs (see Factory Default Sengs
in Program Mode ).
3.3 Remote Input
Use the input wire to program the sensor remotely. To program the sensor using the input wire, remote input must be enabled (inPT
SEL = SEt). The remote input provides limited programming opons (see the gure below). Pulse the remote input according to the
gures and the instrucons provided in this manual.

3.4 Sync Master/Slave
Up to seven DF-G2 High Speed Expert Dual Display Fiber Amplier with Dual Discrete Outputs and IO Link sensors may be used together
in a single sensing applicaon. To eliminate crosstalk between the sensors, congure one sensor to be the master and the remaining
sensors to be the slaves. In this mode, the sensors alternate taking measurements and the response speed is 2 ms.
Note: Note: In this mode, all sensors must either be NPN or PNP output models.
1. Congure the rst sensor as the Master (inPt SEL = MAST).
2. In the Master sensor set-up, enter the total number of Slave sensors you will be using (tOtL SLAV = 1 - 6).
3. For each Slave sensor used, congure the input as a Slave (inPt SEL = SLVE).
4. Give each Slave its own idenfying address (SLAV Addr = 1 - 6).
5. Connect the Input wires of the Master and all of the Slaves together.
Note: Note: Giving two Slave sensors the same address will cause them to re their emiers at the same me in the ring
sequence.
3.5 Adjust Mode
Sliding the RUN/PRG/ADJ mode switch to the ADJ posion allows the user to perform Expert TEACH/SET methods and Manual
Adjustment of the threshold(s).
Note: For the Dual Output models, when teaching CH2, the gain seng will be the same as the gain seng made during the CH1
teach. Reteaching CH1 may invalidate the previous CH2 teach.
3.5.1 TEACH Procedures
The instrucon manual has detailed instrucons for these TEACH modes:
•Two-Point TEACH
• Dynamic TEACH
• Window SET
• Light SET
DF-G2 High Speed Expert Dual Display Fiber Amplier with Dual Discrete Outputs and IO Link

• Dark SET
•Calibraon SET
Two-Point TEACH
•Establishes a single switching threshold
• Threshold can be adjusted by using the "+" and "-" rocker buon (Manual Adjust)
Two-Point TEACH is used when two condions can be presented stacally to the sensor. The sensor locates a single sensing threshold
(the switch point) midway between the two taught condions, with the Output ON condion on one side, and the Output OFF condion
on the other.

Dynamic TEACH
•Teaches on-the-y
• Establishes a single switching threshold
•Threshold can be adjusted using "+" and "-" rocker buon (Manual Adjust)
Dynamic TEACH is best used when a machine or process may not be stopped for teaching. The sensor learns during actual sensing
condions, taking mulple samples of the light and dark condions and automacally seng the threshold at the opmum level.
