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. The dip-switches 6-7-8 allow users to couple the single devices to
the 2 muting channels available on the SG-BWS-T4-MT control unit. Following table reports all the available combinations.

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.”
Note: When only 1 muting lamp is used, please connect
on the clamps of the other one a 150 ohm > 5W resistor!
