Description
A selected sensor supplied an
unknown signal to the
sc1000 network.
Channel 1 of the RTC module
started the substitutional strategy.
Channel 2 of the RTC module
started the substitutional strategy.
RTC analogue input signal is
defective.
A user-defined parameter sets a
limit for the RTC operation.
RTC module receives less
measurement values than
necessary. This warning likely
occurs with the SENSOR MISSING
warning.
Description
There is no communication
between RTC module and
RTC communication card.
The communication between
RTC module and RTC
communication card was
cancelled.
The sensor selection of the
RTC module was removed by
removal or selection of a new
sc1000 controller.
Too many sensors selected in
the SELECT SENSOR menu.
The probes selected in the
SELECT SENSOR have too
many measurements to be
operates by the RTC
communication card.
Contact technical support.
Channel 1 of the RTC module started the
substitutional strategy (e.g., missing
measurement values).
Channel 2 of the RTC module started the
substitutional strategy (e.g., missing
measurement values).
Fix the analogue signal supply to RTC module.
If necessary, make sure that the limiting
parameters are correctly set. Make necessary
adjustments.
Make sure that all necessary instruments are
selected in the SELECT SENSOR menu.
Solution
Supply RTC module with voltage.
Examine the connection cable.
Set the power of the sc1000 and the RTC module to
off. Wait until the system is completely voltage free. Set
the power of the sc1000 controller and the RTC module
to on.
Make sure that the +/- connections of the connector
cable between RTC and RTC communication card in
the sc1000 are installed correctly. Make the necessary
changes.
