Caution
Malfunctions due to exceeding of the maximum permissible current consumption.
– Make sure that the current consumption from U
EL/SEN
does not exceed the maxim­
um permissible value of 1.6 A per I-Port.
– Make sure that the current consumption from U
VAL
does not exceed the maximum
permissible value of 1.6 A per I-Port.
– Make sure that the total current consumption of the CTEL system does not exceed
the maximum permissible 9 A (with deduction of the other consumers within the
voltage zone).
Note
The supply of the actuators via the load voltage supply U
VAL
can occur in an isolated
manner compared to U
EL/SEN
.
3.6 Connection with the host system
For the required connection between the CTEL master module in the CPX terminal and the higher-order
host system, it is required that the configuration file entry that corresponds to the current I/O configur­
ation presetting of the CTEL master module is selected in the host system.
Only in this case is the CTEL master module correctly recognised when the system is run up.
Otherwise, communication cannot be established and no diagnostic/error message is issued.
