Instruction Manual C200
A
C200
column gauge that comprises IMBus modules is configured in a fixed order. If one single
C200
is to
be configured, the power supply module ( No. 1 ) always has to be fitted first, followed by the
IMB-mc1
measuring controller module ( No. 2 ) and then subsequently ( starting with No. 3 ) the IMBus measuring
and interface modules in any chosen order. The fitting order of the IMBus measuring and interface modules
as a result determines the address assignment (
P1
to
P8
) of the connected sensors or measuring instru-
ments. The
C200
column gauge can read in a maximum of 8 connected sensors or measuring instruments.
If several
C200
are to be connected, the
IMB-cas
adapter cable ( No. 1 ) has to be fitted first, followed by
the power supply module ( No. 2 ), then the
IMB-mc1
measuring controller and subsequently the IMBus
measuring and interface modules in any chosen order.
One power supply module can supply power to a maximum of 3
C200
column gauges in this way. If more
than 3
C200
are interconnected, an additional power supply module has to be fitted to the fourth
C200
at
the latest.
Extension cables can be used to place the particular IMBus modules nearby the measuring places, if nec-
essary. Sensitive signal leads from inductive probes, for instance, or long pneumatic hoses for pneumatic
measuring configurations can be avoided in this way. The total maximum length of all IMBus extension ca-
bles must not exceed 1200 m.
2.3.2 Connecting the IMBus modules
(1)
Push both red levers of the first module against the stop and rotate to the stop
( set up )
.
(2)
Connect modules.
(3)
Rotate back both red levers to lock the modules while pressing them together.
Follow steps
(1)
,
(2)
and
(3)
to connect the IMBus modules one after the other.
The following table indicates the installation sequence of the IMBus modules.
Position 1 is the bottom position later on, and is screwed to the base of the C200 column gauge.
!!! Important : The bottom IMBus module must be equipped with bolts to do so.
