Mold Area Free (MAF) Light Curtain

Description

This section describes the EUROMAP use of a Mold Area Free (MAF) light curtain.
 

The IMMI Mold Area Free (MAF) signals are not intended for safeguarding of personnel.

  • Apply safeguarding if there is a risk of operators reaching into the mold.

  • Integrate safeguarding in accordance with applicable standards, for example: IEC 62046, ISO 13855.

Failure to use a Mold Area Free (MAF) light curtain can result in unplanned mold closure which can cause equipment damage.

  • Use the IMMI to signal the state of the MAF light curtain, if used.

The 24 V supply available from the MAF connector on the IMMI module is current limited. Exceeding the specified output current can result in a stop.
 

The MAF light curtain signal is not for safety purposes; it simply provides a status signal to the IMM.

Connect the MAF using the dedicated digital MAF input connector on the IMMI module. The MAF input is a pnp-type. When connected, the MAF input is high when the light curtain is not obstructed.
