Significance for Power LED

System voltage (>12V) available

System connection in the

Cube20 system is interrupted, no. of flashing pulses corresponds to the position of the faulty expansion module

(1…15), with several modules the closest one

Example:

Remedy

Replacement of the affected module and power reset at terminal UB of the Cube20

BN module off No system power (<12V) Increase voltage

4.1.2 (In the corresponding product manual!) Meaning of the "Bus Run"

LED and the "Cfg F" LED states

They are described in the Cube20 product manuals. For an overview please refer to

the beginning of this manual, chapter "About the User Manual and its Structure".

4.1.3 Displays for Supply Voltage at the Terminals of All Modules

4.1.3.1 Module Supply

There is no LED at terminal "UB". The state of system voltage is signalized by the

Power LED.

See chapter: Significance of the states of the "Power" LED

Indicators „UI“ show the state of the supply voltage for the internal supply.

Indicators „UA“ show the state of the supply voltage for actuators.

4.1.4 Signal Logic State and LED Behavior

4.1.4.1 Digital modules

A separate status indicator is assigned for each input and output. It is labeled with "00…03" or

"00…07". Furthermore, the labeling corresponds to channel number and bit position. It is situated under the corresponding terminal and allows easy mapping to the state of the peripheral components, sensors and actuators.

When inductive loads are switched off, the diagnostic LED on the output channel of modules 56118 and 56168 may light up briefly. This does not represent a module malfunction. The module does not sustain any damage.
