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 (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:
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 elec-
trostatic discharge via the monitor electronics.
