  • Page 21: Product Features

    SECTION 2 Product features The MS4800 safety light curtain family is available in two versions. These ver- sions are identified as the MS4800-EA and EB versions. Configuration of the safety light curtains can be changed through selector switches located under an access cover.

    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 configu- ration. The protected machine is allowed to operate. Pressing and releasing the start button has no effect.

  • Page 24: Operating Modes

    MS4800FS Requirements The MS4800FS is offered in protective heights ranging from 280 mm to 1800 mm for 14 mm resolution and 280 mm to 2120 mm for 30 mm resolu- tion. • An MS4800FS system has a maximum size limitation based on the num- ber of beams.
  • Page 25 The MS4800FS will enter a fault condition, indicated by error code "95" on the indicators in the bottom part of the device. This fault code indicates that there was a reduction in the number of cascaded segments. If the number of segments is reduced while power is off, the light curtain will power on with fault code "100".
  • Page 26 MS4800FS Cascaded Series Section 4-3...

  • Page 27: Detection Options

    Each Fixed Blanked area has a size and positional tolerance of ±1 beam to allow for slight position variance and only the two beams on the edges of the blanked area are allowed to vary. Because of this position tolerance, a reduc- tion of the optical resolution takes place on the border area of Fixed Blanking patterns.
  • Page 28 Blanked areas. For only this case, there is no positional tolerance allowed on that side of the clear beam for the object closest to the entry endcap so that clear beam can only be used by the object further away from the entry end- cap.
  • Page 29 Start switch is activated to clear the fault. When the receiver powers up it will be in Fixed Blanking mode with the red and amber LEDs lit. 2. The authorized user then...
  • Page 30 Blanking switches off and in Fixed Blanking is disabled. then on. The user may start normal operation by a press and release of the start button or by per- forming a power cycle. 6. To exit Fixed Blanking the user sets both selector IBIs of blocked beams on.

  • Page 31: Floating Blanking

    Please refer to chapter 5-4 Opti- cal Synchronization for further details. This means that an object can freely float from one end of the protective field to the other without the MS4800 system entering the MACHINE STOP state.

  • Page 32: Fixed Blanking With Floating Blanking

    The increase is equal to the beam spacing distance for each beam that is disabled. If the size of the object detected by the system increases the minimum safe distance must also be increased. Use the minimum object sensitivity given in the following tables to determine the new figure to use when computing the safety distance.

  • Page 33: Optical Synchronization

    To establish synchro- nization the system needs to have a certain number of consecutive clear beams (see following table) within the first master segment. If they are not sat- isfied, the system will enter a MACHINE STOP state and every other Individ- ual Beam Indicator will light.

  • Page 35: Diagnostic And Test Features

    The MS4800 offers operating range selection: short range is 3 m and long range is 7 m for the 14 mm models. For the 30mm models the short range is 8m and long range is 20 m. This function is useful when there are many light curtains operating within a small space and the possibility of cross-talk is likely.

  • Page 37: Using Selector Switches To Set Features

    Using selector switches to set features !WARNING Make sure that foreign objects such as water, oil, or dust do not enter the inside of the MS4800 system while the cover for the selector switches is open. Access to the selector switches The switches are located behind a flip door on both the transmitter and receiver.

  • Page 38: Operating Mode Selection

    Selecting External Device Monitoring (EDM) EDM is activated by setting position 2 of Switches A and B located on the receiver. Any mismatch between the settings of Switches A and B will result in an alarm condition.

  • Page 39: Selecting Scan Codes

    Selecting Scan Codes The MS4800 receiver and transmitter offer scan code selection to minimize cross talk. On the transmitter this is activated by setting position 1. On the receiver this is activated by setting position 3 of switch A and switch B.
  • Page 40 Selecting Scan Codes Section 7-7...

  • Page 41: Outputs

    This is not a safety output. The MS4800 system supplies one auxiliary output. The configuration of this output is "PNP follow". So the signal on the auxiliary output is similar to the status of the OSSD outputs. It will source up to 100 mA at 24 VDC.
  • Page 42 Auxiliary Output Section 8-2...

  • Page 43: Safe Mounting Distances

    An MS4800 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 44 If the result of the calcula- tion is less than 100 mm, a distance of at least 100 mm must still be maintained. Approach speed in mm/s. In the close area of 500 mm, the speed is calculated at 2000 mm/s.

  • Page 45: Safety Distance For Safeguarding Danger Areas

    Additional countermeasures may be necessary to prevent access to the dan- gerous area from above, below, the sides or the rear of the machine. The height of the protective field "H" above the reference plane and the reso- lution "d" of the MS4800 system have the following relationship:...

  • Page 47: Installation

    SECTION 10 Installation !WARNING Install the sensor system so that it is not affected by reflective surfaces. Fail- ure to do so may hinder detection, resulting in serious injury. 10-1 Reflective Surface Interference 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.

  • Page 48: Cross Talk Mitigation

    To mitigate interference from other light curtains, the MS4800 system has two possible scan codes, A and B. The transmitter and receiver units must be set to the same scan code for the receiver to enter the MACHINE RUN state.

  • Page 49: General Mounting Considerations

    10-3 General Mounting Considerations 10-3-1 Additional Guarding Areas of access to the point of hazardous operation not guarded by the MS4800 system must be protected by suitable means such as a fixed barrier guard, an interlocked guard or a safety mat system.
  • Page 50 The system detection zone is delineated by the inside edge of the transmitter and receiver endcaps. The area outside these marks is not protected. Position the system so that it is only possible to access the danger point through the detection zone.
  • Page 51 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. Opera- tion of the MS4800 system In the Start/Restart Interlock operating mode is suitable for perimeter guarding.

  • Page 53: Connection To The Machine Control Circuit

    !WARNING Never use only a single safety output to control the machine. Should this sin- gle output fail, the machine may not stop, resulting in severe operator injury. The machine must be connected using both safety outputs.

  • Page 54: Interconnect Cables For Cascaded Ms4800Fs System

    The maximum cable length is 10 meters between segments. The extension cables are available in lengths of 0.3 m, 0.5 m, 1 m, 2 m, 5 m and 10 m. A MS4800FS system does not require an extension cable; it has a 150 mm integrated cable (pigtail).

  • Page 57: Muting

    Install muting sensors so that they can distinguish between the object that is being allowed to pass through the detection zone and a person. If the muting function is activated by the detection of a person, it may result in serious injury.
  • Page 58 3. The MS4800 system performs a system reboot. When this sequence is properly completed, muting function is enabled. The status LED of the receiver turns to green and the status LED of the RM6 lights permanently. When this sequence is properly completed, the system will enable muting.
