Instruction Manual C200
Important
:
Should an IMBus module already be equipped with bolts
( e.g.
IMB-ps2
when using an
IMB-cas
adapter cable )
, please replace the bolts with 2 cross-recessed screws SH-UNC / 4-40*9.5
( included in shipment )
in order to enable connecting of modules.
2.3.3 Fitting of bus terminator
Prior to inserting the modules into the column profile, the bus terminator connector is attached to
the vacant port of the last module and screwed to it.
If the last module has not been fitted with bolts to fix the terminator connector, both cross-recessed
screws will have to be removed and replaced with bolts.
The bolts are included in the shipment !!!
About the bus terminator :
The purpose of the bus terminator is to terminate the bus lines electrically, to seal the open port,
and to provide information on the function and the power supply of the column gauge.
The
“VCC”
LED lights up when the power supply to the column gauge is secured. The
“VCC”
LED
will be extinguished, if the power supply module has been overloaded due to external consumers,
such as digital probes with high current consumption, or as a result of voltage drops due to long
IMBus extension cables. The IMBus design, however, allows adding power supply modules
between any IMBus gauging and interface modules at will, to compensate voltage drops.
The
“RUN”
LED lights up, when the self-test of all IMBus modules has finished successfully.
The
“RUN”
LED will not light up and will thus signal that the IMBus could not be completely
checked, if more IMBus modules have been fitted than can be addressed by the column gauge.
Note
:
The
“RUN”
LED will not issue an error message in this case, but instead signalises the
incomplete self-test of modules that cannot be addressed.
