- Page 3 "EC Type Approval (TYPE 4 ESPE)" in accordance with the Machinery Directive, from TÜV Rheinland. Notice If you use the F3SL under the condition or environment shown below, be sure to use it by leaving a mar- gin for each rating and function and taking system safety into consideration.
- Page 4 Install the F3SL system so as not to be affected by the reflection from the reflective surface. Failure to do so may cause the system undetectable, resulting in severe operator injury.

Page 7: Important Safety Warnings
F3SL. If the F3SL is used as a safety device, the user has the responsibility to insure that applicable national, fed- eral and local safety rules, codes and regulations are satisfied. In addition, the user should insure that all machine operators, maintenance personnel, electricians, supervisors, etc. -
Page 8: Theory Of Operation
“redundant” microprocessor design combined with extensive fault mode and effects analysis provides safe, control reliable operation. A F3SL system consists of one emitter and one receiver. No interconnecting cables or separate control enclo- sure are required. 2-2 Technical Specifications... - Page 9 Aluminum Accessories Test rod(ø30), mounting hardware (top, bottom), operating instructions, hexago- Ω nal wrench exclusive for program button access, 2 load resistors for test (10 k ), 2 surge killer Applicable standard IEC(EN)61496-1 TYPE4 ESPE *1 IEC61496-2 TYPE4 AOPD *2 *1.

Page 12: System Operation
4-1-1 Machine Run The two receiver safety outputs are in the ON state, the green machine run indicator is lit, and the auxiliary output is in a state consistent with its configuration. See Section 7-2 on page 13. The protected machine is allowed to operate. -
Page 13: Operating Mode Selection
Operating mode is selected by setting positions 1 and 2 of Switches A and B, located inside the receiver end cap. Refer to Table 4-1. Any mismatch between the settings of Switch A and B will result in an alarm condition. -
Page 14: Detection Options
Up to two channels can be disabled at any location in the detection zone (except for the synchronization beam) without the F3SL system going to the machine stop state. The disabled channels are not fixed at a single location but “float” through the detection zone. -
Page 15: Using Exact Channel Select With Floating Blanking
The safety distance must be increased. Failure to do so may cause serious injury. To prevent a hand or other objects to enter the channel-selected part, provide a physical guard such as a fence. When both Exact Channel Select and Floating Blanking are selected, the floating channels are allowed to occur anywhere within the detection zone (except for the beam nearest the cable), even within the area selected by Exact Channel Select. -
Page 16: The Effect Of Exact Channel Select And Floating Blanking On Minimum Object Resolution
Exact Channel Select is activated by setting position 4 of Switches A and B, located inside the receivere end cap. Refer Figure 3-1 and Table 5-5. Any mismatch between the settings of Switches A and B will result in a alarm condition. -
Page 17: Activating Floating Blanking
5-5 Activating Floating Blanking Floating Blanking (either one- or two- beam) is activated by setting positions 5 and 6 of Switches A and B located inside the receiver end cap. Refer to Figure 3-1 and Table 5-5. Any mismatch between the settings of Switch A and B will result in an alarm condition. -
Page 18: Diagnostic And Test Features
MPCE monitoring is activated by setting position 3 of Switches A and B located inside the receiver end cap. Re- fer to Figure 3-1 and Table 6-1. Any mismatch between the settings of Switches A and B will result in an alarm condition. -
Page 19: Outputs
24 VDC. In the machine stop state, the outputs are not electrically conducting. Note: The safety outputs must have a minimum load or the F3SL system will enter a alarm condition. For the purpose of testing prior to final installation, this load can be supplied by a 10K ohm resistor (included in documentation kit). -
Page 20: Safe Mounting Distance
A F3SL system must be mounted far enough from the machine danger zone so the machine will stop before a hand or other body part reaches the hazardous area. This distance is called the safety distance. It is a calculated number based on a formula. -
Page 21: Safety Distance Formula For Systems With A Minimum Object Resolution Greater Than 40 Mm
100 mm. If S is found to be greater than 500 mm using the formula above, then the formula below can be used. In this case the minimum value of S shall not be less than 500 mm. - Page 22 Note: If the guarded machine is not equipped with a stop time performance monitor, a percentage increase fac- tor should be applied to the stop time of the machine to allow for braking system wear. Contact your ma- chine manufacturer for information.

Page 23: Installation
A reflective surface adjacent to the detection zone can deflect the optical beam and may cause an obstruction in the zone not to be detected. (See Figure 9-2 and Figure 9-3.) The reflective surface may be part of the ma- chine, mechanical guard or workpiece. - Page 24 Receiver Beam Angle, a Reflective Surface Perimeter of danger area Figure 9-4 Worst Case Alignment Example This example shows the minimum distance from the reflective surface, d, to one side of the beam center line. 1.3m 1.1m d(mm) 0.3m Range (m)

Page 25: General Considerations
9-2-1 Additional Guarding Areas of access to the point of hazardous operation not guarded by the F3SL system must be protected by suit- able means such as a fixed barrier guard, an interlocked guard or a safety mat. See Figure 9-6. -
Page 26: Access To Configuration Switches
Switches to configure the F3SL system operating features are located inside the end cap of the receiver and Exact Channel Select is programmed via a push button accessed from the front of this end cap. If it will be nec- essary to change the configuration or Exact Channel Select program during operation, access to this cap must be maintained. -
Page 27: Cable Assemblies
In this case, the guarded machine must only be restarted using a switch located outside and with a full view of the area of hazardous motion. Operation of the F3SL system in the start/restart interlock operating mode is suit- able for perimeter guarding. -
Page 28: Connecting To The Machine Control Circuit
Note 2: If the MPCE monitor function is not used, short circuit the MPCE monitor line (pink) to 0V power supply. Note 3: When the load is not connected to control outputs 1 and 2, this system will enter error state and not operate properly. -
