Connection hood and degree of protection IP65
Ä Before connecting, mount the connection hood on the BPS device housing.
Ä To ensure degree of protection IP65 is fulfilled, the screws of the connection hood are tight-
ened with a tightening torque of 1.4Nm for connecting to the BPS.

For all connections (connection cable, interconnection cable, etc.), use only the cables listed in
the accessories (see chapter 14 "Order guide and accessories").
7.1 External parameter memory in the connection hood
To enable simple exchange of the BPS, the integrated parameter memory of the MS307 and MK307 con-
nection hoods store a copy of the current parameter set.
Also located in the MS307 and MK307 are switches S1 and S2.
• Slide switch S1 is used to toggle the encoding of the output measurement value between Gray and bi-
nary.
• Rotary switch S2 is used to set the resolution of the position value (in mm) or a speed monitoring func-
tion.
NOTICE
No parameter memory and no configuration switches in connection hood KB307!
Ä No parameter memory is integrated in connection hood KB307.
Ä Connection hood KB307 does not include any switches for configuring the BPS.
