Muting with FMC and FMI Units

The FMC Focus Muting Connector is a small, optimal unit which is used when the Focus Light Curtain or Light Grid is required to be bypassed for in and out passage to and from a dangerous area. The FMC unit is easily connected to Focus with an M12 connector. The FMI Focus Muting Indicator is a small unit with built-in muting lamp, reset button, “power off” (for alignment and override). The FMI unit is connected to the FMC unit with M12 connectors to facilitate the muting function connection.

Various FMC, FMI, FRM Versions and Tina Units			FMC-1(2): With connectors for muting sensors (A+B), reset, power off and muting lamp (r) and (M). FMI-1A: Only muting lamps. FMI-1B: With reset, power off and muting lamp. FMI-1C: With reset and power off. FMI-1D: With reset, power off and resistor instead of muting lamp. FMI-1E: As pre-reset fitted in connector A (A2) on FMC-1(2) (Tina) or as reset for Tina Duo 2 in (R) connector. FMI-1G: With reset and resistor instead of muting lamp. FMC-1(2) Tina: The same as FMC-1(2) but made for connectin of Vital or Pluto. Tina 10A: Adapter unit for connection of Vital or Pluto. Tina 10B: Simplified FMC-1(2) Tina but with only (R) connector. Tina 10C: Simplified FMC-1(2) Tina but with only power feed at connector 3. M12-3M: Bypass unit for easy connection outside the enclosure. FRM-1A: Converts the two OSSD outputs to relay outputs (and power feed). JS SP-1: Blanking plug for unused inputs. JS AP-1: Adapter for FMC units for use without FMI-1B or FMI-1D at (R) connector with muting resistor.

Connection of Focus and Muting Components with FMC1 and FMI1

Connection of light curtain with connection block FMC1, text/reset button 1 and switch for supplyvoltage placed in or by the control cabinet.

Connection of light curtain with connectionblock FMC1. The FMI reset unit must be placedout of reach from the risk area.

Connection of Focus and Muting Components directly to Control Cabinet

The test/reset button shall be placed so the operator can see the protected area during reset, testing and bypassing, It should not be possible to reach the button from within the risk area.

The LMS lamp for indication of muting and bypassing shall be placed so that it can be seen from all directions from where it is possible to access the dangerous area.

If photocells are used as muting sensors, the sensor receivers should be assembled on the light curtain’s transmitter side to minimize the interference risk.

The system is protected against dangerous functions caused by damage on the transmitter cable and/or the receiver cable. However, we recommend that the cables be protected so that physical damage to them can be minimized.

Focus Modular Muting Capabilities

The Focus Safety Light Curtain offers the selection of complete muting of the protective field during the in and out passage of material. Through dipswitch settings in the Focus standard version, it is also capable of muting only specific modules within the protective field.The Focus is capable of muting independent beam module packets or a combination of them (up to 4).For example, a box travels down a conveyor and instead of muting the entire light curtain you can mute only modules 1 and 2 — which equates to the height of the box — allowing continual protection on the remaining Safety Light Curtain modules.The module size is directly dependent on the Focus Light Curtain resolution and length.
