SETTINGS • User interface is present on the top of the SG-BWS-T4 for signalling and configuration. • Two units made of 8 dip-switches are present on the top of the SG-BWS-T4-MT model. These switches activate/deactivate and configure additional functions integrated in the device. • Signalling interface and dip-switches are protected from nonauthorized access by transparent lids that can be opened using a specific tool.

DOUBLE MUTING FUNCTION SETTING
Thanks to its two separate muting channels, SG-BWS-T4-MT can accept the muting request output by sensors without interrupting the safety function on light curtain or safety sensors of both channels. PHOTOCELLS

MUTING WARNING DEVICES To use the Muting function it is also required to connect the external Muting warning (lamp) since control unit would lock out if it is missing. One lamp shall be used per channel. If device is preset for use of just one channel, both warning devices are associated to it: in this way, failure of one of the lamps would not lock out system operation. SG-BWS-T4-MT allows installation of both incandescent lamps and LEDs. For the latter case, polarity shall be carefully complied with, as indicated aside.
Note: the Muting lamp is not supplied with the device. Please refer to “Accessory selection and order information table.�
