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
connection 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
binary
.
• Rotary switch S2 is used to set the resolution of the position value (in mm) or a speed monitoring
function.
CAUTION
Safety notices!
Before connecting the device, be sure that the supply voltage agrees with the value printed on the
name plate.
Only allow competent persons to perform the electrical connection.
Ensure that the functional earth (FE) is connected correctly.
Fault-free operation is only guaranteed if the functional earth is connected properly.
If faults cannot be rectified, take the device out of operation. Protect the device from accidentally being
started.
CAUTION
UL applications!
For UL applications, use is only permitted in Class 2 circuits in accordance with the NEC (National
Electric Code).
NOTICE
Protective Extra Low Voltage (PELV)
The BPS is designed in accordance with protection class III for supply with PELV (protective extra-low
voltage).
NOTICE
Connection hood and degree of protection IP 65
Before connecting, mount the connection hood on the BPS device housing.
To ensure degree of protection IP 65 is fulfilled, the screws of the connection hood are tightened with
a tightening torque of 1.4 Nm for connecting to the BPS.
Degree of protection IP 65 is not fulfilled until connectors or cable bushings are screwed on and caps
are installed.
For all connections (connection cable, interconnection cable, etc.), use only the cables listed in
the accessories (see chapter 14).
NOTICE
No parameter memory and no configuration switches in connection hood KB 307!
No parameter memory is integrated in connection hood KB 307.
Connection hood KB 307 does not include any switches for configuring the BPS.
