Operative malfunctions due to insufficient power supply.
Supply of the load voltage supply V
•
ciently dimensioned to be able to supply the connected
actuators.
Observe that, dependent on the respective length of the
•
I-port connecting cable and current consumption of the
connected I-port device, a voltage drop results between
the CTEL master module and the device.
Therefore, when I-port connecting cables >5 m are used,
the operating voltage supply V
fallen below by more than 10 %.
The total current requirement of the CPX terminal and
•
the CTEL system as well as the limit values for the max-
imum current intensities must be taken into account in
the design of the voltage supply (see section 2.5.2
and 2.5.3).
