DFS11
Digital Fiber Optic Sensor
AN ALL INCLUSIVE FIBER OPTIC SENSOR

The Digital Fiber Optic Sensor is designed to provide reliable detection using plastic fiber optic light guides. The slim-line housing with protective lid will fit in a variety of small spaces. The DFS is adjusted by a single push of a button; there is no guess work on the part of the operator. The sensor default settings will work for most applications. The DFS is as simple or as complicated as you would like. If your application is a bit more complex, the DFS can be adjusted in many configurations.

AUTOSET MODE
The sensor's automatic threshold adjustment is controlled by one of six AUTOSET modes: Light State (LS), Dark State (DS), Midpoint (MP), Two-Point (2P), Dynamic (DY), and Window (WN).

AUTOSET PERCENT
For Light State (LS), Dark State (DS), and Window (WN), the offset percentage is adjustable. AUTOSET percent determines threshold placement during AUTOSET. Placement is a percentage of received light beam intensity.

DETECT MODE
Selects between Light On or Dark On Mode. When Autoset mode is set to Window (WN) the Detect Mode effects the output state when the light level is inside the two window thresholds.

RESPONSE TIME
Choose between five different settings ranging from fastest speed to highest resolution: Ultra-High-Speed (UHS), High-Speed (HS), Standard (STD), High-Resolution (HR), Long-Range (LR), Ultra-Long-Range (ULR).

HYSTERESIS
Adjusts the span between the operate point and the release point of the sensor output to avoid false triggers for example due to object vibration. Low hysteresis increases sensitivity and high hysteresis increases sensing stability.

ANTI-CROSSTALK
Link up to eight sensors together to eliminate light interference between sensors. Asynchronous cross-talk allows rejection of light interference from one DFS to another without a wired connection. Synchronous crosstalk rejection synchronizes via one wire up to eight DFS units to be used together without interference.

TIMER
Choose from 19 pre-configured timer control functions. Each timer represents a function such as on-delay, off-delay, etc. Once a function is selected, adjustable parameters of that function appear such as delay time.

OUTPUT TYPE
The sensor has configurable Q1 (primary; black wire) and Q2 (secondary; white wire) I/O signals. Select the way the connector signals function and route: Single Output with Remote Input, Redundant, Complementary, and Classic.

OUTPUT MODE
When configured as an output Q1 and Q2 can be set one of three ways: PNP - Source, NPN - Sink, or Push/Pull..

INPUT FUNCTIONS
When Q2 is programmed as an input, several different functions can be performed: Remote set, Remote command, Interrogate, Gate, Remote Dark On, and Remote Lockout.

INPUT MODE
Select the active state of the input: Active High or Low.

DISPLAY MODE
Selects between numeric and percentage modes, and flips orientation.

LOCK MODE
Prevents unauthorized tampering.

Using AUTOSET

The DFS threshold is set automatically by pressing the AUTOSET button. There are six different ways the sensor determines the threshold. The user first must determine which type of setup mode is appropriate for the application. The simplest and most common mode we recommend is Light State (LS) setup. It is used in both beam make and beam break sensing. When using this mode, the sensor will provide the best sensitivity to fine changes in light level or contrast. This is useful for small part detection and precise leading-edge triggering. Please consult Fundamentals or contact one of our worldwide distributors for application help. We look forward to providing any assistance you may need. Note: OLED display will provide intuitive visual feedback during autosetting. Paying close attention to the display is important.
Light State (Default) Place object to be detected in the worst-case lightstate condition and press the AUTOSET button. The threshold will be set 10%(default) below the received light-beam intensity. The threshold can be altered by tapping up or down on the threshold adjust rocker (see Figure 1).
Dark State Place object to be detected in the worst-case darkstate condition and press the AUTOSET button. The threshold will be set 10%(default) above the received light-beam intensity. The threshold can be altered by tapping up or down on the threshold adjust rocker (see Figure 2).
Midpoint Place object to be detected in position at which you want the threshold to be set and press the AUTOSET button. The threshold can be altered by tapping up or down on the threshold adjust rocker (see Figure 3).
Two-Point Place object to be detected in the light-state condition and press the AUTOSET button. Then remove or place the object in the dark-state condition and press the AUTOSET button again. The threshold will be set between the two light-beam intensities. The threshold can be altered by tapping up or down on the threshold adjust rocker (see Figure 4).
Dynamic Press the AUTOSET button to start the Dynamic AUTOSET. Now move the object through the beam at least once and press the AUTOSET button again to complete the Dynamic AUTOSET. The threshold is set between the highest and lowest received light levels caused by the object being passed through. The threshold can be altered by tapping up or down on the threshold adjust rocker (see Figure 5).
Window Window mode is a unique type of AUTOSET mode. Window mode creates two thresholds and can be used in a similar manor as a dual channel fiber optic sensor. Place the object in the position at which you want to be reliably detect it and press the AUTOSET button. The DFS will place two thresholds 10%(default) higher and 10%(default) lower than the returned light level. Now when the object is passed in view or through the fiber optic the object will be detected in the same position +/-10%. The threshold offset (both thresholds) can be altered by tapping up or down on the threshold adjust rocker (see Figure 6).
