Making internal assignments
You have to make the following assignments:
1) Assign the QE1 contactor control to the relay output which controls the coil
of the network contactor (right).
2) Assign the QE2 contactor control to the relay output which controls the coil
of the network contactor (left).
3) Assign the QE4 contactor control to an arbitrary relay output from which the
"ON input" of the soft starter should be controlled.
4) Assign the QE3 contactor control to the relay output that supplies the 20 ms
acknowledgment signal to the soft starter.
5) Assign the "ON >", "ON <" and "OFF" control commands to the enabled
control commands.
6) Assign the SIMOCODE pro input to which the "Fault" signal output of the soft
starter is connected to the input (socket) of the standard function "External
fault 1".
7) The "Start-up end" signal of the soft starter can also be wired to one of the
inputs and processed by SIMOCODE pro.
Note
An additional digital module may be necessary for this control function.
