Bearing Vibration Monitor
i
For trouble−free operation of the RS 485 bus, the lines "A" and "B" in one
monitor must be connected on their references (+5 V, ground), this is only
possible if the bus terminator jumper is also set in this monitor.
Sensor raw−signal
The raw sensor signal (in−phase output signal of the converter without Bias−voltage) applied
to the front panel SMB sockets, can be switched over with the J2 jumpers on terminals z14:
channel 1 and z16: channel 2 of the connection strip. The controller board must be removed in
order to switch the signal on the connection strip. The following points describe the procedure:
i
The reference point for the raw sensor signal from channel 1 is the connection
strip terminal b22: GND, and for the raw sensor from channel 2 the terminal
b24: GND.
When working at the monitor, ensure that there is adequate protection against
STOP
electrostatic discharge. For examle, wear an ESD bracelet to prevent
electrostatic discharge via the monitor electronics.
3. Use a cross−head screwdriver to remove the four cross−headed screws, identified with the
arrows, in the following figure.
4. Carefully pull the controller board off the main board without tilting it. The position of the J2
jumpers on the main bard is identified with a white frame in the following figure.
