Muting light curtain for import and export of products

A safety light curtain shields a hazardous area for people's access. When there is no access for persons, but the access for products must be available, a muting light curtain offers a perfect solution. With a muting light screen, access to a hazardous area is temporarily disabled (muting), allowing products to enter the hazardous area.

Setup of a muting light curtain

With a muting light curtain from ReeR Safety it is possible to safely import and export products in a T-arrangement. With an L-arrangement it is only possible to export products. If a person goes through the light screen, the machine will stop. In addition to T-arrangement and L-arrangement, it is also possible to apply muting in I-setup.

Status and muting lamp - Safegate - ReeR Safety
Status lamp on muting light curtain | ReeR


The muting lamp that is standard on the muting light screen in the SMO and SMPO series indicates the status of the muting application. For people around the muting application it is always clear whether problems occur.

Status display on muting light curtain

The status lamp of the SMO and SMPO series shows the state of the muting application. For people around the machine it is therefore immediately clear whether the muting is working properly. If an operator has to reset the light screen or operate the override button, this is immediately visible via this status lamp.



Partial muting of secured height

In the programmable variants of the Safegate, the secured height can also be partially muted.

This ensures a higher safety level when a pallet is stacked only low. After all, the operator could easily enter the machine over the low stacking because the security was switched off during the muting process. When the light curtain is partially switched off, the upper safety light beams remain active during the muting.
