Product Information / Produktinformation A6110
Shaft Vibration Monitor
For trouble−free operation of the RS 485 bus, the lines "A" and "B" must be
i
connected on their references (+5 V, ground) in one monitor. This is only
possible when the bus terminator jumper in this monitor has been closed as
well.
Sensor raw signal
The raw sensor signal (unfiltered, in−phase output signal of the converter with AC and DC
portion) 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. As delivered, the J2 jumpers
are set, that on terminals z14 and z16 the dynamic portion of the sensor signal (scaled to output
range 0 ... 20 Vss) is applied. The controller board must be removed in order to switch the signal
on the connection strip. The following points describe the procedure:
The reference point for the raw sensor signal from channel 1 is the connection
i
strip terminal z6: SENS1+, and for the raw sensor signal from channel 2 the
terminal d6: SENS2+. If these terminals are connected with terminal b10, then
the reference point lies on system ground (GND). In this case the terninals
b22: GND and b24: GND can be used as reference point.
When working at the monitor, ensure that there is adequate protection against
STOP electrostatic discharge. For example, wear an ESD bracelet to prevent
electrostatic discharge via the monitor electronics.
